Bin

The #GtkBin widget is a container with just one child. It is not very useful itself, but it is useful for deriving subclasses, since it provides common code needed for handling a single child widget.

Many GTK+ widgets are subclasses of #GtkBin, including #GtkWindow, #GtkButton, #GtkFrame, #GtkHandleBox or #GtkScrolledWindow.

Constructors

this
this(GtkBin* gtkBin, bool ownedRef)

Sets our main struct and passes it to the parent class.

Functions

getBinStruct
GtkBin* getBinStruct(bool transferOwnership)

Get the main Gtk struct

getChild
Widget getChild()

Gets the child of the #GtkBin, or %NULL if the bin contains no child widget. The returned widget does not have a reference added, so you do not need to unref it.

getStruct
void* getStruct()

the main Gtk struct as a void*

getType
GType getType()
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.

checkResize
void checkResize()
childGetProperty
void childGetProperty(Widget child, string propertyName, Value value)

Gets the value of a child property for @child and @container.

childGetValist
void childGetValist(Widget child, string firstPropertyName, void* varArgs)

Gets the values of one or more child properties for @child and @container.

childNotify
void childNotify(Widget child, string childProperty)

Emits a #GtkWidget::child-notify signal for the [child property][child-properties] @child_property on the child.

childNotifyByPspec
void childNotifyByPspec(Widget child, ParamSpec pspec)

Emits a #GtkWidget::child-notify signal for the [child property][child-properties] specified by @pspec on the child.

childSetProperty
void childSetProperty(Widget child, string propertyName, Value value)

Sets a child property for @child and @container.

childSetValist
void childSetValist(Widget child, string firstPropertyName, void* varArgs)

Sets one or more child properties for @child and @container.

childType
GType childType()

Returns the type of the children supported by the container.

forall
void forall(GtkCallback callback, void* callbackData)

Invokes @callback on each direct child of @container, including children that are considered “internal” (implementation details of the container). “Internal” children generally weren’t added by the user of the container, but were added by the container implementation itself.

foreac
alias foreac = foreach_
Undocumented in source.
foreach_
void foreach_(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.

getBorderWidth
uint getBorderWidth()

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().
