TreeView

Widget that displays any object that implements the #GtkTreeModel interface.

Please refer to the [tree widget conceptual overview]TreeWidget for an overview of all the objects and data types related to the tree widget and how they work together.

Several different coordinate systems are exposed in the GtkTreeView API. These are:

Coordinate systems in GtkTreeView API:

- Widget coordinates: Coordinates relative to the widget (usually widget->window).

- Bin window coordinates: Coordinates relative to the window that GtkTreeView renders to.

- Tree coordinates: Coordinates relative to the entire scrollable area of GtkTreeView. These coordinates start at (0, 0) for row 0 of the tree.

Several functions are available for converting between the different coordinate systems. The most common translations are between widget and bin window coordinates and between bin window and tree coordinates. For the former you can use gtk_tree_view_convert_widget_to_bin_window_coords() (and vice versa), for the latter gtk_tree_view_convert_bin_window_to_tree_coords() (and vice versa).

GtkTreeView as GtkBuildable

The GtkTreeView implementation of the GtkBuildable interface accepts #GtkTreeViewColumn objects as <child> elements and exposes the internal #GtkTreeSelection in UI definitions.

An example of a UI definition fragment with GtkTreeView: |[ <object class="GtkTreeView" id="treeview"> <property name="model">liststore1</property> <child> <object class="GtkTreeViewColumn" id="test-column"> <property name="title">Test</property> <child> <object class="GtkCellRendererText" id="test-renderer"/> <attributes> <attribute name="text">1</attribute> </attributes> </child> </object> </child> <child internal-child="selection"> <object class="GtkTreeSelection" id="selection"> <signal name="changed" handler="on_treeview_selection_changed"/> </object> </child> </object> ]|

CSS nodes

|[<!-- language="plain" --> treeview.view ├── header │ ├── <column header> ┊ ┊ │ ╰── <column header> │ ╰── rubberband ]|

GtkTreeView has a main CSS node with name treeview and style class .view. It has a subnode with name header, which is the parent for all the column header widgets' CSS nodes. For rubberband selection, a subnode with name rubberband is used.

class TreeView : Container , ScrollableIF {}

int expandRow(TreeIter iter, TreeModelIF model, bool openAll)

Expands the row of the iter.

expandRow
bool expandRow(TreePath path, bool openAll)

Opens the row so its children are visible.

Expands the row at @path. This will also expand all parent rows of @path as necessary.

getActivateOnSingleClick
bool getActivateOnSingleClick()

Gets the setting set by gtk_tree_view_set_activate_on_single_click().

getBackgroundArea
void getBackgroundArea(TreePath path, TreeViewColumn column, GdkRectangle rect)

Fills the bounding rectangle in bin_window coordinates for the cell at the row specified by @path and the column specified by @column. If @path is %NULL, or points to a node not found in the tree, the @y and @height fields of the rectangle will be filled with 0. If @column is %NULL, the @x and @width fields will be filled with 0. The returned rectangle is equivalent to the @background_area passed to gtk_cell_renderer_render(). These background areas tile to cover the entire bin window. Contrast with the @cell_area, returned by gtk_tree_view_get_cell_area(), which returns only the cell itself, excluding surrounding borders and the tree expander area.

getBinWindow
Window getBinWindow()

Returns the window that @tree_view renders to. This is used primarily to compare to event->window to confirm that the event on @tree_view is on the right window.

getCellArea
void getCellArea(TreePath path, TreeViewColumn column, GdkRectangle rect)

Fills the bounding rectangle in bin_window coordinates for the cell at the row specified by @path and the column specified by @column. If @path is %NULL, or points to a path not currently displayed, the @y and @height fields of the rectangle will be filled with 0. If @column is %NULL, the @x and @width fields will be filled with 0. The sum of all cell rects does not cover the entire tree; there are extra pixels in between rows, for example. The returned rectangle is equivalent to the @cell_area passed to gtk_cell_renderer_render(). This function is only valid if @tree_view is realized.

getColumn
TreeViewColumn getColumn(int n)

Gets the #GtkTreeViewColumn at the given position in the #tree_view.

getColumns
ListG getColumns()

Returns a #GList of all the #GtkTreeViewColumn s currently in @tree_view. The returned list must be freed with g_list_free ().

getCursor
void getCursor(TreePath path, TreeViewColumn focusColumn)

Fills in @path and @focus_column with the current path and focus column. If the cursor isn’t currently set, then *@path will be %NULL. If no column currently has focus, then *@focus_column will be %NULL.

getDestRowAtPos
bool getDestRowAtPos(int dragX, int dragY, TreePath path, GtkTreeViewDropPosition pos)

Determines the destination row for a given position. @drag_x and @drag_y are expected to be in widget coordinates. This function is only meaningful if @tree_view is realized. Therefore this function will always return %FALSE if @tree_view is not realized or does not have a model.

getDragDestRow
void getDragDestRow(TreePath path, GtkTreeViewDropPosition pos)

Gets information about the row that is highlighted for feedback.

getEnableSearch
bool getEnableSearch()

Returns whether or not the tree allows to start interactive searching by typing in text.

getEnableTreeLines
bool getEnableTreeLines()

Returns whether or not tree lines are drawn in @tree_view.

getExpanderColumn
TreeViewColumn getExpanderColumn()

Returns the column that is the current expander column. This column has the expander arrow drawn next to it.

getFixedHeightMode
bool getFixedHeightMode()

Returns whether fixed height mode is turned on for @tree_view.

getGridLines
GtkTreeViewGridLines getGridLines()

Returns which grid lines are enabled in @tree_view.

getHeadersClickable
bool getHeadersClickable()

Returns whether all header columns are clickable.

Returns the model the #GtkTreeView is based on. Returns %NULL if the model is unset.

getNColumns
uint getNColumns()

Queries the number of columns in the given @tree_view.

getPathAtPos
bool getPathAtPos(int x, int y, TreePath path, TreeViewColumn column, int cellX, int cellY)

Finds the path at the point (@x, @y), relative to bin_window coordinates (please see gtk_tree_view_get_bin_window()). That is, @x and @y are relative to an events coordinates. @x and @y must come from an event on the @tree_view only where `event->window == gtk_tree_view_get_bin_window ()`. It is primarily for things like popup menus. If @path is non-%NULL, then it will be filled with the #GtkTreePath at that point. This path should be freed with gtk_tree_path_free(). If @column is non-%NULL, then it will be filled with the column at that point. @cell_x and @cell_y return the coordinates relative to the cell background (i.e. the @background_area passed to gtk_cell_renderer_render()). This function is only meaningful if @tree_view is realized. Therefore this function will always return %FALSE if @tree_view is not realized or does not have a model.

getReorderable
bool getReorderable()

Retrieves whether the user can reorder the tree via drag-and-drop. See gtk_tree_view_set_reorderable().

getRowSeparatorFunc
GtkTreeViewRowSeparatorFunc getRowSeparatorFunc()

Returns the current row separator function.

getRubberBanding

Gets the setting set by gtk_tree_view_set_rules_hint().

getSearchColumn
int getSearchColumn()

Gets the column searched on by the interactive search code.

getSearchEntry

Returns whether or not expanders are drawn in @tree_view.

getStruct
void* getStruct()

the main Gtk struct as a void*

getTooltipColumn
int getTooltipColumn()

Returns the column of @tree_view’s model which is being used for displaying tooltips on @tree_view’s rows.

getTooltipContext
bool getTooltipContext(int x, int y, bool keyboardTip, TreeModelIF model, TreePath path, TreeIter iter)

This function is supposed to be used in a #GtkWidget::query-tooltip signal handler for #GtkTreeView. The @x, @y and @keyboard_tip values which are received in the signal handler, should be passed to this function without modification.

getTreeViewStruct
GtkTreeView* getTreeViewStruct(bool transferOwnership)

Get the main Gtk struct

getVisibleRange
bool getVisibleRange(TreePath startPath, TreePath endPath)

Sets @start_path and @end_path to be the first and last visible path. Note that there may be invisible paths in between.

getVisibleRect
void getVisibleRect(GdkRectangle visibleRect)

Fills @visible_rect with the currently-visible region of the buffer, in tree coordinates. Convert to bin_window coordinates with gtk_tree_view_convert_tree_to_bin_window_coords(). Tree coordinates start at 0,0 for row 0 of the tree, and cover the entire scrollable area of the tree.

insertColumn
int insertColumn(TreeViewColumn column, int position)

This inserts the @column into the @tree_view at @position. If @position is -1, then the column is inserted at the end. If @tree_view has “fixed_height” mode enabled, then @column must have its “sizing” property set to be GTK_TREE_VIEW_COLUMN_FIXED.

insertColumnWithDataFunc
int insertColumnWithDataFunc(int position, string title, CellRenderer cell, GtkTreeCellDataFunc func, void* data, GDestroyNotify dnotify)

Convenience function that inserts a new column into the #GtkTreeView with the given cell renderer and a #GtkTreeCellDataFunc to set cell renderer attributes (normally using data from the model). See also gtk_tree_view_column_set_cell_data_func(), gtk_tree_view_column_pack_start(). If @tree_view has “fixed_height” mode enabled, then the new column will have its “sizing” property set to be GTK_TREE_VIEW_COLUMN_FIXED.

insertEditableColumn
int insertEditableColumn(int position, string title, CellRenderer renderer, bool editable)

Inserts a column and sets it's attributes

isBlankAtPos
bool isBlankAtPos(int x, int y, TreePath path, TreeViewColumn column, int cellX, int cellY)

Determine whether the point (@x, @y) in @tree_view is blank, that is no cell content nor an expander arrow is drawn at the location. If so, the location can be considered as the background. You might wish to take special action on clicks on the background, such as clearing a current selection, having a custom context menu or starting rubber banding.

isRubberBandingActive
bool isRubberBandingActive()

Returns whether a rubber banding operation is currently being done in @tree_view.

mapExpandedRows
void mapExpandedRows(GtkTreeViewMappingFunc func, void* data)

Calls @func on all expanded rows.

moveColumnAfter
void moveColumnAfter(TreeViewColumn column, TreeViewColumn baseColumn)

Moves @column to be after to @base_column. If @base_column is %NULL, then @column is placed in the first position.

removeColumn
int removeColumn(TreeViewColumn column)

Removes @column from @tree_view.

rowActivated
void rowActivated(TreePath path, TreeViewColumn column)

Activates the cell determined by @path and @column.

rowExpanded
bool rowExpanded(TreePath path)

Returns %TRUE if the node pointed to by @path is expanded in @tree_view.

scrollToCell
void scrollToCell(TreePath path, TreeViewColumn column, bool useAlign, float rowAlign, float colAlign)

Moves the alignments of @tree_view to the position specified by @column and @path. If @column is %NULL, then no horizontal scrolling occurs. Likewise, if @path is %NULL no vertical scrolling occurs. At a minimum, one of @column or @path need to be non-%NULL. @row_align determines where the row is placed, and @col_align determines where @column is placed. Both are expected to be between 0.0 and 1.0. 0.0 means left/top alignment, 1.0 means right/bottom alignment, 0.5 means center.

scrollToPoint
void scrollToPoint(int treeX, int treeY)

Scrolls the tree view such that the top-left corner of the visible area is @tree_x, @tree_y, where @tree_x and @tree_y are specified in tree coordinates. The @tree_view must be realized before this function is called. If it isn't, you probably want to be using gtk_tree_view_scroll_to_cell().

setActivateOnSingleClick
void setActivateOnSingleClick(bool single)

Cause the #GtkTreeView::row-activated signal to be emitted on a single click instead of a double click.

setColumnDragFunction
void setColumnDragFunction(GtkTreeViewColumnDropFunc func, void* userData, GDestroyNotify destroy)

Sets a user function for determining where a column may be dropped when dragged. This function is called on every column pair in turn at the beginning of a column drag to determine where a drop can take place. The arguments passed to @func are: the @tree_view, the #GtkTreeViewColumn being dragged, the two #GtkTreeViewColumn s determining the drop spot, and @user_data. If either of the #GtkTreeViewColumn arguments for the drop spot are %NULL, then they indicate an edge. If @func is set to be %NULL, then @tree_view reverts to the default behavior of allowing all columns to be dropped everywhere.

setCursor
void setCursor(TreePath path, TreeViewColumn focusColumn, bool startEditing)

Sets the current keyboard focus to be at @path, and selects it. This is useful when you want to focus the user’s attention on a particular row. If @focus_column is not %NULL, then focus is given to the column specified by it. Additionally, if @focus_column is specified, and @start_editing is %TRUE, then editing should be started in the specified cell. This function is often followed by @gtk_widget_grab_focus (@tree_view) in order to give keyboard focus to the widget. Please note that editing can only happen when the widget is realized.

setCursorOnCell
void setCursorOnCell(TreePath path, TreeViewColumn focusColumn, CellRenderer focusCell, bool startEditing)

Sets the current keyboard focus to be at @path, and selects it. This is useful when you want to focus the user’s attention on a particular row. If @focus_column is not %NULL, then focus is given to the column specified by it. If @focus_column and @focus_cell are not %NULL, and @focus_column contains 2 or more editable or activatable cells, then focus is given to the cell specified by @focus_cell. Additionally, if @focus_column is specified, and @start_editing is %TRUE, then editing should be started in the specified cell. This function is often followed by @gtk_widget_grab_focus (@tree_view) in order to give keyboard focus to the widget. Please note that editing can only happen when the widget is realized.

setDestroyCountFunc
void setDestroyCountFunc(GtkTreeDestroyCountFunc func, void* data, GDestroyNotify destroy)

This function should almost never be used. It is meant for private use by ATK for determining the number of visible children that are removed when the user collapses a row, or a row is deleted.

setDragDestRow
void setDragDestRow(TreePath path, GtkTreeViewDropPosition pos)

Sets the row that is highlighted for feedback. If @path is %NULL, an existing highlight is removed.

setEnableSearch
void setEnableSearch(bool enableSearch)

If @enable_search is set, then the user can type in text to search through the tree interactively (this is sometimes called "typeahead find").

setEnableTreeLines
void setEnableTreeLines(bool enabled)

Sets whether to draw lines interconnecting the expanders in @tree_view. This does not have any visible effects for lists.

setExpanderColumn
void setExpanderColumn(TreeViewColumn column)

Sets the column to draw the expander arrow at. It must be in @tree_view. If @column is %NULL, then the expander arrow is always at the first visible column.

setFixedHeightMode
void setFixedHeightMode(bool enable)

Enables or disables the fixed height mode of @tree_view. Fixed height mode speeds up #GtkTreeView by assuming that all rows have the same height. Only enable this option if all rows are the same height and all columns are of type %GTK_TREE_VIEW_COLUMN_FIXED.

setGridLines
void setGridLines(GtkTreeViewGridLines gridLines)

Sets which grid lines to draw in @tree_view.

setHeadersClickable
void setHeadersClickable(bool setting)

Allow the column title buttons to be clicked.

setHeadersVisible
void setHeadersVisible(bool headersVisible)

Sets the visibility state of the headers.

setHoverExpand
void setHoverExpand(bool expand)

Enables or disables the hover expansion mode of @tree_view. Hover expansion makes rows expand or collapse if the pointer moves over them.

setHoverSelection
void setHoverSelection(bool hover)

Enables or disables the hover selection mode of @tree_view. Hover selection makes the selected row follow the pointer. Currently, this works only for the selection modes %GTK_SELECTION_SINGLE and %GTK_SELECTION_BROWSE.

setLevelIndentation
void setLevelIndentation(int indentation)

Sets the amount of extra indentation for child levels to use in @tree_view in addition to the default indentation. The value should be specified in pixels, a value of 0 disables this feature and in this case only the default indentation will be used. This does not have any visible effects for lists.

setModel
void setModel(TreeModelIF model)

Sets the model for a #GtkTreeView. If the @tree_view already has a model set, it will remove it before setting the new model. If @model is %NULL, then it will unset the old model.

setReorderable
void setReorderable(bool reorderable)

This function is a convenience function to allow you to reorder models that support the #GtkTreeDragSourceIface and the #GtkTreeDragDestIface. Both #GtkTreeStore and #GtkListStore support these. If @reorderable is %TRUE, then the user can reorder the model by dragging and dropping rows. The developer can listen to these changes by connecting to the model’s #GtkTreeModel::row-inserted and #GtkTreeModel::row-deleted signals. The reordering is implemented by setting up the tree view as a drag source and destination. Therefore, drag and drop can not be used in a reorderable view for any other purpose.

setRowSeparatorFunc
void setRowSeparatorFunc(GtkTreeViewRowSeparatorFunc func, void* data, GDestroyNotify destroy)

Sets the row separator function, which is used to determine whether a row should be drawn as a separator. If the row separator function is %NULL, no separators are drawn. This is the default value.

setRubberBanding
void setRubberBanding(bool enable)

Enables or disables rubber banding in @tree_view. If the selection mode is #GTK_SELECTION_MULTIPLE, rubber banding will allow the user to select multiple rows by dragging the mouse.

setRulesHint
void setRulesHint(bool setting)

Sets a hint for the theme to draw even/odd rows in the @tree_view with different colors, also known as "zebra striping".

setSearchColumn
void setSearchColumn(int column)

Sets @column as the column where the interactive search code should search in for the current model.

setSearchEntry
void setSearchEntry(Entry entry)

Sets the entry which the interactive search code will use for this @tree_view. This is useful when you want to provide a search entry in our interface at all time at a fixed position. Passing %NULL for @entry will make the interactive search code use the built-in popup entry again.

setSearchEqualFunc
void setSearchEqualFunc(GtkTreeViewSearchEqualFunc searchEqualFunc, void* searchUserData, GDestroyNotify searchDestroy)

Sets the compare function for the interactive search capabilities; note that somewhat like strcmp() returning 0 for equality #GtkTreeViewSearchEqualFunc returns %FALSE on matches.

setSearchPositionFunc
void setSearchPositionFunc(GtkTreeViewSearchPositionFunc func, void* data, GDestroyNotify destroy)

Sets the function to use when positioning the search dialog.

setShowExpanders
void setShowExpanders(bool enabled)

Sets whether to draw and enable expanders and indent child rows in @tree_view. When disabled there will be no expanders visible in trees and there will be no way to expand and collapse rows by default. Also note that hiding the expanders will disable the default indentation. You can set a custom indentation in this case using gtk_tree_view_set_level_indentation(). This does not have any visible effects for lists.

setTooltipCell
void setTooltipCell(Tooltip tooltip, TreePath path, TreeViewColumn column, CellRenderer cell)

Sets the tip area of @tooltip to the area @path, @column and @cell have in common. For example if @path is %NULL and @column is set, the tip area will be set to the full area covered by @column. See also gtk_tooltip_set_tip_area().

setTooltipColumn
void setTooltipColumn(int column)

If you only plan to have simple (text-only) tooltips on full rows, you can use this function to have #GtkTreeView handle these automatically for you. @column should be set to the column in @tree_view’s model containing the tooltip texts, or -1 to disable this feature.

setTooltipRow
void setTooltipRow(Tooltip tooltip, TreePath path)

Sets the tip area of @tooltip to be the area covered by the row at @path. See also gtk_tree_view_set_tooltip_column() for a simpler alternative. See also gtk_tooltip_set_tip_area().

unsetRowsDragDest
void unsetRowsDragDest()

Undoes the effect of gtk_tree_view_enable_model_drag_dest(). Calling this method sets #GtkTreeView:reorderable to %FALSE.

unsetRowsDragSource
void unsetRowsDragSource()

Undoes the effect of gtk_tree_view_enable_model_drag_source(). Calling this method sets #GtkTreeView:reorderable to %FALSE.

add
void add(Widget widget)

Adds @widget to @container. Typically used for simple containers such as #GtkWindow, #GtkFrame, or #GtkButton; for more complicated layout containers such as #GtkBox or #GtkGrid, this function will pick default packing parameters that may not be correct. So consider functions such as gtk_box_pack_start() and gtk_grid_attach() as an alternative to gtk_container_add() in those cases. A widget may be added to only one container at a time; you can’t place the same widget inside two different containers.

foreac
void foreac(GtkCallback callback, void* callbackData)

Invokes @callback on each non-internal child of @container. See gtk_container_forall() for details on what constitutes an “internal” child. For all practical purposes, this function should iterate over precisely those child widgets that were added to the container by the application with explicit add() calls.

Retrieves the border width of the container. See gtk_container_set_border_width().

getChildren
ListG getChildren()

Returns the container’s non-internal children. See gtk_container_forall() for details on what constitutes an "internal" child.

getFocusChain
bool getFocusChain(ListG focusableWidgets)

Retrieves the focus chain of the container, if one has been set explicitly. If no focus chain has been explicitly set, GTK+ computes the focus chain based on the positions of the children. In that case, GTK+ stores %NULL in @focusable_widgets and returns %FALSE.

getFocusChild
Widget getFocusChild()

Returns the current focus child widget inside @container. This is not the currently focused widget. That can be obtained by calling gtk_window_get_focus().

getFocusHadjustment
Adjustment getFocusHadjustment()

Retrieves the horizontal focus adjustment for the container. See gtk_container_set_focus_hadjustment ().

getFocusVadjustment
Adjustment getFocusVadjustment()

Retrieves the vertical focus adjustment for the container. See gtk_container_set_focus_vadjustment().

getPathForChild
WidgetPath getPathForChild(Widget child)

Returns a newly created widget path representing all the widget hierarchy from the toplevel down to and including @child.

getResizeMode
GtkResizeMode getResizeMode()

Returns the resize mode for the container. See gtk_container_set_resize_mode ().

propagateDraw
void propagateDraw(Widget child, Context cr)

When a container receives a call to the draw function, it must send synthetic #GtkWidget::draw calls to all children that don’t have their own #GdkWindows. This function provides a convenient way of doing this. A container, when it receives a call to its #GtkWidget::draw function, calls gtk_container_propagate_draw() once for each child, passing in the @cr the container received.

remove
void remove(Widget widget)

Removes @widget from @container. @widget must be inside @container. Note that @container will own a reference to @widget, and that this may be the last reference held; so removing a widget from its container can destroy that widget. If you want to use @widget again, you need to add a reference to it before removing it from a container, using g_object_ref(). If you don’t want to use @widget again it’s usually more efficient to simply destroy it directly using gtk_widget_destroy() since this will remove it from the container and help break any circular reference count cycles.

resizeChildren
void resizeChildren()
setBorderWidth
void setBorderWidth(uint borderWidth)

Sets the border width of the container.

setFocusChain
void setFocusChain(ListG focusableWidgets)

Sets a focus chain, overriding the one computed automatically by GTK+.

setFocusChild
void setFocusChild(Widget child)

Sets, or unsets if @child is %NULL, the focused child of @container.

setFocusHadjustment
void setFocusHadjustment(Adjustment adjustment)

Hooks up an adjustment to focus handling in a container, so when a child of the container is focused, the adjustment is scrolled to show that widget. This function sets the horizontal alignment. See gtk_scrolled_window_get_hadjustment() for a typical way of obtaining the adjustment and gtk_container_set_focus_vadjustment() for setting the vertical adjustment.

setFocusVadjustment
void setFocusVadjustment(Adjustment adjustment)

Hooks up an adjustment to focus handling in a container, so when a child of the container is focused, the adjustment is scrolled to show that widget. This function sets the vertical alignment. See gtk_scrolled_window_get_vadjustment() for a typical way of obtaining the adjustment and gtk_container_set_focus_hadjustment() for setting the horizontal adjustment.

setReallocateRedraws
void setReallocateRedraws(bool needsRedraws)

Sets the @reallocate_redraws flag of the container to the given value.

setResizeMode
void setResizeMode(GtkResizeMode resizeMode)

Sets the resize mode for the container.

unsetFocusChain
void unsetFocusChain()

Removes a focus chain explicitly set with gtk_container_set_focus_chain().

addOnAdd
gulong addOnAdd(void delegate(Widget, Container) dlg, ConnectFlags connectFlags)
addOnCheckResize
gulong addOnCheckResize(void delegate(Container) dlg, ConnectFlags connectFlags)
addOnRemove
gulong addOnRemove(void delegate(Widget, Container) dlg, ConnectFlags connectFlags)
addOnSetFocusChild
gulong addOnSetFocusChild(void delegate(Widget, Container) dlg, ConnectFlags connectFlags)

From ScrollableIF

getScrollableStruct
GtkScrollable* getScrollableStruct(bool transferOwnership)

Get the main Gtk struct

getStruct
void* getStruct()

the main Gtk struct as a void*

getType
GType getType()
getBorder
bool getBorder(Border border)

Returns the size of a non-scrolling border around the outside of the scrollable. An example for this would be treeview headers. GTK+ can use this information to display overlayed graphics, like the overshoot indication, at the right position.

getHadjustment
Adjustment getHadjustment()

Retrieves the #GtkAdjustment used for horizontal scrolling.

getHscrollPolicy
GtkScrollablePolicy getHscrollPolicy()

Gets the horizontal #GtkScrollablePolicy.

getVadjustment
Adjustment getVadjustment()

Retrieves the #GtkAdjustment used for vertical scrolling.

getVscrollPolicy
GtkScrollablePolicy getVscrollPolicy()

Gets the vertical #GtkScrollablePolicy.

setHadjustment
void setHadjustment(Adjustment hadjustment)

Sets the horizontal adjustment of the #GtkScrollable.

setHscrollPolicy
void setHscrollPolicy(GtkScrollablePolicy policy)

Sets the #GtkScrollablePolicy to determine whether horizontal scrolling should start below the minimum width or below the natural width.

setVadjustment
void setVadjustment(Adjustment vadjustment)

Sets the vertical adjustment of the #GtkScrollable.

setVscrollPolicy
void setVscrollPolicy(GtkScrollablePolicy policy)

Sets the #GtkScrollablePolicy to determine whether vertical scrolling should start below the minimum height or below the natural height.
