TreeViewColumn

The GtkTreeViewColumn object represents a visible column in a #GtkTreeView widget. It allows to set properties of the column header, and functions as a holding pen for the cell renderers which determine how the data in the column is displayed.

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.

Members

Functions

addOnClicked
gulong addOnClicked(void delegate(TreeViewColumn) dlg, ConnectFlags connectFlags)
cellGetPosition
bool cellGetPosition(CellRenderer cellRenderer, int xOffset, int width)

Obtains the horizontal position and size of a cell in a column. If the cell is not found in the column, @start_pos and @width are not changed and %FALSE is returned.

cellGetSize
void cellGetSize(GdkRectangle* cellArea, int xOffset, int yOffset, int width, int height)

Obtains the width and height needed to render the column. This is used primarily by the #GtkTreeView.

cellIsVisible
bool cellIsVisible()

Returns %TRUE if any of the cells packed into the @tree_column are visible. For this to be meaningful, you must first initialize the cells with gtk_tree_view_column_cell_set_cell_data()

cellSetCellData
void cellSetCellData(TreeModelIF treeModel, TreeIter iter, bool isExpander, bool isExpanded)

Sets the cell renderer based on the @tree_model and @iter. That is, for every attribute mapping in @tree_column, it will get a value from the set column on the @iter, and use that value to set the attribute on the cell renderer. This is used primarily by the #GtkTreeView.

clicked
void clicked()

Emits the “clicked” signal on the column. This function will only work if @tree_column is clickable.

focusCell
void focusCell(CellRenderer cell)

Sets the current keyboard focus to be at @cell, if the column contains 2 or more editable and activatable cells.

getAlignment
float getAlignment()

Returns the current x alignment of @tree_column. This value can range between 0.0 and 1.0.

getButton
Button getButton()

Returns the button used in the treeview column header

getClickable
bool getClickable()

Returns %TRUE if the user can click on the header for the column.

getExpand
bool getExpand()

Returns %TRUE if the column expands to fill available space.

getFixedWidth
int getFixedWidth()

Gets the fixed width of the column. This may not be the actual displayed width of the column; for that, use gtk_tree_view_column_get_width().

getMaxWidth
int getMaxWidth()

Returns the maximum width in pixels of the @tree_column, or -1 if no maximum width is set.

getMinWidth
int getMinWidth()

Returns the minimum width in pixels of the @tree_column, or -1 if no minimum width is set.

getReorderable
bool getReorderable()

Returns %TRUE if the @tree_column can be reordered by the user.

getResizable
bool getResizable()

Returns %TRUE if the @tree_column can be resized by the end user.

getSizing
GtkTreeViewColumnSizing getSizing()

Returns the current type of @tree_column.

getSortColumnId
int getSortColumnId()

Gets the logical @sort_column_id that the model sorts on when this column is selected for sorting. See gtk_tree_view_column_set_sort_column_id().

getSortIndicator
bool getSortIndicator()

Gets the value set by gtk_tree_view_column_set_sort_indicator().

getSortOrder
GtkSortType getSortOrder()

Gets the value set by gtk_tree_view_column_set_sort_order().

getSpacing
int getSpacing()

Returns the spacing of @tree_column.

getStruct
void* getStruct()

the main Gtk struct as a void*

getTitle
string getTitle()

Returns the title of the widget.

getTreeView
TreeView getTreeView()

Returns the GtkTreeView wherein tree_column has been inserted. If column is currently not inserted in any tree view, NULL is returned. Since 2.12

getTreeViewColumnStruct
GtkTreeViewColumn* getTreeViewColumnStruct(bool transferOwnership)

Get the main Gtk struct

getVisible
bool getVisible()

Returns %TRUE if @tree_column is visible.

getWidget
Widget getWidget()

Returns the #GtkWidget in the button on the column header. If a custom widget has not been set then %NULL is returned.

getWidth
int getWidth()

Returns the current size of @tree_column in pixels.

getXOffset
int getXOffset()

Returns the current X offset of @tree_column in pixels.

queueResize
void queueResize()

Flags the column, and the cell renderers added to this column, to have their sizes renegotiated.

setAlignment
void setAlignment(float xalign)

Sets the alignment of the title or custom widget inside the column header. The alignment determines its location inside the button -- 0.0 for left, 0.5 for center, 1.0 for right.

setCellDataFunc
void setCellDataFunc(CellRenderer cellRenderer, GtkTreeCellDataFunc func, void* funcData, GDestroyNotify destroy)

Sets the #GtkTreeCellDataFunc to use for the column. This function is used instead of the standard attributes mapping for setting the column value, and should set the value of @tree_column's cell renderer as appropriate. @func may be %NULL to remove an older one.

setClickable
void setClickable(bool clickable)

Sets the header to be active if @clickable is %TRUE. When the header is active, then it can take keyboard focus, and can be clicked.

setExpand
void setExpand(bool expand)

Sets the column to take available extra space. This space is shared equally amongst all columns that have the expand set to %TRUE. If no column has this option set, then the last column gets all extra space. By default, every column is created with this %FALSE.

setFixedWidth
void setFixedWidth(int fixedWidth)

If @fixed_width is not -1, sets the fixed width of @tree_column; otherwise unsets it. The effective value of @fixed_width is clamped between the minimum and maximum width of the column; however, the value stored in the “fixed-width” property is not clamped. If the column sizing is #GTK_TREE_VIEW_COLUMN_GROW_ONLY or #GTK_TREE_VIEW_COLUMN_AUTOSIZE, setting a fixed width overrides the automatically calculated width. Note that @fixed_width is only a hint to GTK+; the width actually allocated to the column may be greater or less than requested.

setMaxWidth
void setMaxWidth(int maxWidth)

Sets the maximum width of the @tree_column. If @max_width is -1, then the maximum width is unset. Note, the column can actually be wider than max width if it’s the last column in a view. In this case, the column expands to fill any extra space.

setMinWidth
void setMinWidth(int minWidth)

Sets the minimum width of the @tree_column. If @min_width is -1, then the minimum width is unset.

setReorderable
void setReorderable(bool reorderable)

If @reorderable is %TRUE, then the column can be reordered by the end user dragging the header.

setResizable
void setResizable(bool resizable)

If @resizable is %TRUE, then the user can explicitly resize the column by grabbing the outer edge of the column button. If resizable is %TRUE and sizing mode of the column is #GTK_TREE_VIEW_COLUMN_AUTOSIZE, then the sizing mode is changed to #GTK_TREE_VIEW_COLUMN_GROW_ONLY.

setSizing
void setSizing(GtkTreeViewColumnSizing type)

Sets the growth behavior of @tree_column to @type.

setSortColumnId
void setSortColumnId(int sortColumnId)

Sets the logical @sort_column_id that this column sorts on when this column is selected for sorting. Doing so makes the column header clickable.

setSortIndicator
void setSortIndicator(bool setting)

Call this function with a @setting of %TRUE to display an arrow in the header button indicating the column is sorted. Call gtk_tree_view_column_set_sort_order() to change the direction of the arrow.

setSortOrder
void setSortOrder(GtkSortType order)

Changes the appearance of the sort indicator.

setSpacing
void setSpacing(int spacing)

Sets the spacing field of @tree_column, which is the number of pixels to place between cell renderers packed into it.

setTitle
void setTitle(string title)

Sets the title of the @tree_column. If a custom widget has been set, then this value is ignored.

setVisible
void setVisible(bool visible)

Sets the visibility of @tree_column.

setWidget
void setWidget(Widget widget)

Sets the widget in the header to be @widget. If widget is %NULL, then the header button is set with a #GtkLabel set to the title of @tree_column.

addOnNotify
gulong addOnNotify(void delegate(ParamSpec, ObjectG) dlg, string property, ConnectFlags connectFlags)

The notify signal is emitted on an object when one of its properties has been changed. Note that getting this signal doesn't guarantee that the value of the property has actually changed, it may also be emitted when the setter for the property is called to reinstate the previous value.

getType
GType getType()
compatControl
size_t compatControl(size_t what, void* data)
interfaceFindProperty
ParamSpec interfaceFindProperty(TypeInterface gIface, string propertyName)

Find the #GParamSpec with the given name for an interface. Generally, the interface vtable passed in as @g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().

interfaceInstallProperty
void interfaceInstallProperty(TypeInterface gIface, ParamSpec pspec)

Add a property to an interface; this is only useful for interfaces that are added to GObject-derived types. Adding a property to an interface forces all objects classes with that interface to have a compatible property. The compatible property could be a newly created #GParamSpec, but normally g_object_class_override_property() will be used so that the object class only needs to provide an implementation and inherits the property description, default value, bounds, and so forth from the interface property.

interfaceListProperties
ParamSpec[] interfaceListProperties(TypeInterface gIface)

Lists the properties of an interface.Generally, the interface vtable passed in as @g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().

addToggleRef
void addToggleRef(GToggleNotify notify, void* data)

Increases the reference count of the object by one and sets a callback to be called when all other references to the object are dropped, or when this is already the last reference to the object and another reference is established.

addWeakPointer
void addWeakPointer(void* weakPointerLocation)

Adds a weak reference from weak_pointer to @object to indicate that the pointer located at @weak_pointer_location is only valid during the lifetime of @object. When the @object is finalized, @weak_pointer will be set to %NULL.

bindProperty
Binding bindProperty(string sourceProperty, ObjectG target, string targetProperty, GBindingFlags flags)

Creates a binding between @source_property on @source and @target_property on @target. Whenever the @source_property is changed the @target_property is updated using the same value. For instance:

bindPropertyFull
Binding bindPropertyFull(string sourceProperty, ObjectG target, string targetProperty, GBindingFlags flags, GBindingTransformFunc transformTo, GBindingTransformFunc transformFrom, void* userData, GDestroyNotify notify)

Complete version of g_object_bind_property().

bindPropertyWithClosures
Binding bindPropertyWithClosures(string sourceProperty, ObjectG target, string targetProperty, GBindingFlags flags, Closure transformTo, Closure transformFrom)

Creates a binding between @source_property on @source and @target_property on @target, allowing you to set the transformation functions to be used by the binding.

dupData
void* dupData(string key, GDuplicateFunc dupFunc, void* userData)

This is a variant of g_object_get_data() which returns a 'duplicate' of the value. @dup_func defines the meaning of 'duplicate' in this context, it could e.g. take a reference on a ref-counted object.

dupQdata
void* dupQdata(GQuark quark, GDuplicateFunc dupFunc, void* userData)

This is a variant of g_object_get_qdata() which returns a 'duplicate' of the value. @dup_func defines the meaning of 'duplicate' in this context, it could e.g. take a reference on a ref-counted object.

forceFloating
void forceFloating()

This function is intended for #GObject implementations to re-enforce a floating[floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling g_object_ref_sink().

freezeNotify
void freezeNotify()

Increases the freeze count on @object. If the freeze count is non-zero, the emission of "notify" signals on @object is stopped. The signals are queued until the freeze count is decreased to zero. Duplicate notifications are squashed so that at most one #GObject::notify signal is emitted for each property modified while the object is frozen.

getData
void* getData(string key)

Gets a named field from the objects table of associations (see g_object_set_data()).

getProperty
void getProperty(string propertyName, Value value)

Gets a property of an object. @value must have been initialized to the expected type of the property (or a type to which the expected type can be transformed) using g_value_init().

getQdata
void* getQdata(GQuark quark)

This function gets back user data pointers stored via g_object_set_qdata().

getValist
void getValist(string firstPropertyName, void* varArgs)

Gets properties of an object.

getv
void getv(string[] names, Value[] values)

Gets @n_properties properties for an @object. Obtained properties will be set to @values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.

isFloating
bool isFloating()

Checks whether @object has a floating[floating-ref] reference.

notify
void notify(string propertyName)

Emits a "notify" signal for the property @property_name on @object.

notifyByPspec
void notifyByPspec(ParamSpec pspec)

Emits a "notify" signal for the property specified by @pspec on @object.

doref
ObjectG doref()

Increases the reference count of @object.

refSink
ObjectG refSink()

Increase the reference count of @object, and possibly remove the floating[floating-ref] reference, if @object has a floating reference.

removeToggleRef
void removeToggleRef(GToggleNotify notify, void* data)

Removes a reference added with g_object_add_toggle_ref(). The reference count of the object is decreased by one.

removeWeakPointer
void removeWeakPointer(void* weakPointerLocation)

Removes a weak reference from @object that was previously added using g_object_add_weak_pointer(). The @weak_pointer_location has to match the one used with g_object_add_weak_pointer().

replaceData
bool replaceData(string key, void* oldval, void* newval, GDestroyNotify destroy, GDestroyNotify oldDestroy)

Compares the user data for the key @key on @object with @oldval, and if they are the same, replaces @oldval with @newval.

replaceQdata
bool replaceQdata(GQuark quark, void* oldval, void* newval, GDestroyNotify destroy, GDestroyNotify oldDestroy)

Compares the user data for the key @quark on @object with @oldval, and if they are the same, replaces @oldval with @newval.

runDispose
void runDispose()

Releases all references to other objects. This can be used to break reference cycles.

setData
void setData(string key, void* data)

Each object carries around a table of associations from strings to pointers. This function lets you set an association.

setDataFull
void setDataFull(string key, void* data, GDestroyNotify destroy)

Like g_object_set_data() except it adds notification for when the association is destroyed, either by setting it to a different value or when the object is destroyed.

setProperty
void setProperty(string propertyName, Value value)

Sets a property on an object.

setQdata
void setQdata(GQuark quark, void* data)

This sets an opaque, named pointer on an object. The name is specified through a #GQuark (retrived e.g. via g_quark_from_static_string()), and the pointer can be gotten back from the @object with g_object_get_qdata() until the @object is finalized. Setting a previously set user data pointer, overrides (frees) the old pointer set, using #NULL as pointer essentially removes the data stored.

setQdataFull
void setQdataFull(GQuark quark, void* data, GDestroyNotify destroy)

This function works like g_object_set_qdata(), but in addition, a void (*destroy) (gpointer) function may be specified which is called with @data as argument when the @object is finalized, or the data is being overwritten by a call to g_object_set_qdata() with the same @quark.

setValist
void setValist(string firstPropertyName, void* varArgs)

Sets properties on an object.

setv
void setv(string[] names, Value[] values)

Sets @n_properties properties for an @object. Properties to be set will be taken from @values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.

stealData
void* stealData(string key)

Remove a specified datum from the object's data associations, without invoking the association's destroy handler.

stealQdata
void* stealQdata(GQuark quark)

This function gets back user data pointers stored via g_object_set_qdata() and removes the @data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update user data pointers with a destroy notifier, for example: |[<!-- language="C" --> void object_add_to_user_list (GObject *object, const gchar *new_string) { // the quark, naming the object data GQuark quark_string_list = g_quark_from_static_string ("my-string-list"); // retrive the old string list GList *list = g_object_steal_qdata (object, quark_string_list);

thawNotify
void thawNotify()

Reverts the effect of a previous call to g_object_freeze_notify(). The freeze count is decreased on @object and when it reaches zero, queued "notify" signals are emitted.

unref
void unref()

Decreases the reference count of @object. When its reference count drops to 0, the object is finalized (i.e. its memory is freed).

watchClosure
void watchClosure(Closure closure)

This function essentially limits the life time of the @closure to the life time of the object. That is, when the object is finalized, the @closure is invalidated by calling g_closure_invalidate() on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, g_object_ref() and g_object_unref() are added as marshal guards to the @closure, to ensure that an extra reference count is held on @object during invocation of the @closure. Usually, this function will be called on closures that use this @object as closure data.

weakRef
void weakRef(GWeakNotify notify, void* data)

Adds a weak reference callback to an object. Weak references are used for notification when an object is finalized. They are called "weak references" because they allow you to safely hold a pointer to an object without calling g_object_ref() (g_object_ref() adds a strong reference, that is, forces the object to stay alive).

weakUnref
void weakUnref(GWeakNotify notify, void* data)

Removes a weak reference callback to an object.

clearObject
void clearObject(ObjectG objectPtr)

Clears a reference to a #GObject.
