Creates a new #GtkLayout. Unless you have a specific adjustment you’d like the layout to use for scrolling, pass null for hadjustment and vadjustment.
Retrieve the bin window of the layout used for drawing operations.
This function should only be called after the layout has been placed in a #GtkScrolledWindow or otherwise configured for scrolling. It returns the #GtkAdjustment used for communication between the horizontal scrollbar and layout.
Gets the size that has been set on the layout, and that determines the total extents of the layout’s scrollbar area. See gtk_layout_set_size ().
This function should only be called after the layout has been placed in a #GtkScrolledWindow or otherwise configured for scrolling. It returns the #GtkAdjustment used for communication between the vertical scrollbar and layout.
Moves a current child of layout to a new position.
Adds child_widget to layout, at position (x,y). layout becomes the new parent container of child_widget.
Returns this, for use in with statements.
Sets the horizontal scroll adjustment for the layout.
Sets the size of the scrollable area of the layout.
Sets the vertical scroll adjustment for the layout.

Get hadjustment property.
Set hadjustment property.
Get hscrollPolicy property.
Set hscrollPolicy property.
Get vadjustment property.
Set vadjustment property.
Get vscrollPolicy property.
Set vscrollPolicy property.
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.
Retrieves the #GtkAdjustment used for horizontal scrolling.
Gets the horizontal #GtkScrollablePolicy.
Retrieves the #GtkAdjustment used for vertical scrolling.
Gets the vertical #GtkScrollablePolicy.
Sets the horizontal adjustment of the #GtkScrollable.
Sets the #GtkScrollablePolicy to determine whether horizontal scrolling should start below the minimum width or below the natural width.
Sets the vertical adjustment of the #GtkScrollable.
Sets the #GtkScrollablePolicy to determine whether vertical scrolling should start below the minimum height or below the natural height.
Returns this, for use in with statements.
Get builder for gtk.container.Container
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.Box.packStart and gtk.grid.Grid.attach as an alternative to gtk.container.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.
Gets the value of a child property for child and container.
Emits a #GtkWidget::child-notify signal for the [child property][child-properties] child_property on the child.
Emits a #GtkWidget::child-notify signal for the [child property][child-properties] specified by pspec on the child.
Sets a child property for child and container.
Returns the type of the children supported by the container.
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.
Invokes callback on each non-internal child of container. See gtk.container.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.Container.setBorderWidth.
Returns the container’s non-internal children. See gtk.container.Container.forall for details on what constitutes an "internal" child.
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.
Returns the current focus child widget inside container. This is not the currently focused widget. That can be obtained by calling gtk.window.Window.getFocus.
Retrieves the horizontal focus adjustment for the container. See gtk_container_set_focus_hadjustment ().
Retrieves the vertical focus adjustment for the container. See gtk.container.Container.setFocusVadjustment.
Returns a newly created widget path representing all the widget hierarchy from the toplevel down to and including child.
Returns the resize mode for the container. See gtk_container_set_resize_mode ().
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.Container.propagateDraw once for each child, passing in the cr the container received.
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 gobject.object.ObjectWrap.ref_. If you don’t want to use widget again it’s usually more efficient to simply destroy it directly using gtk.widget.Widget.destroy since this will remove it from the container and help break any circular reference count cycles.
Sets the border width of the container.
Sets a focus chain, overriding the one computed automatically by GTK+.
Sets, or unsets if child is null, the focused child of container.
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.ScrolledWindow.getHadjustment for a typical way of obtaining the adjustment and gtk.container.Container.setFocusVadjustment for setting the vertical adjustment.

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

Removes a focus chain explicitly set with gtk.container.Container.setFocusChain.

Retrieves the #GtkAdjustment used for vertical scrolling.
Gets the vertical #GtkScrollablePolicy.
Sets the horizontal adjustment of the #GtkScrollable.
Sets the #GtkScrollablePolicy to determine whether horizontal scrolling should start below the minimum width or below the natural width.
Sets the vertical adjustment of the #GtkScrollable.
Sets the #GtkScrollablePolicy to determine whether vertical scrolling should start below the minimum height or below the natural height.
#GtkLayout is similar to #GtkDrawingArea in that it’s a “blank slate” and doesn’t do anything except paint a blank background by default. It’s different in that it supports scrolling natively due to implementing #GtkScrollable, and can contain child widgets since it’s a #GtkContainer.
If you just want to draw, a #GtkDrawingArea is a better choice since it has lower overhead. If you just need to position child widgets at specific points, then #GtkFixed provides that functionality on its own.
When handling expose events on a #GtkLayout, you must draw to the #GdkWindow returned by gtk.layout.Layout.getBinWindow, rather than to the one returned by gtk.widget.Widget.getWindow as you would for a #GtkDrawingArea.
