Description

A GtkLayout is a scrollable widget that provides a scrolling-aware backdrop for a child or children having fixed positions. It should be added directly to a GtkScrolledWindow.

Note that the scrolling does not work on win32 unless you program it to do so. There have been no such problems reported on other systems. The workaround under win32 is to connect the GtkScrolledWindow scrollbar adjustments' "value-changed" signals to a function that will force the GtkLayout to be redrawn. This can be queue_draw() in most situations, but the more complex child widgets will not respond to this alone and will need to have hide() and then show() called on the GtkLayout during the callback.

Note that GtkHtml is based on the GtkLayout class, and that similar redraw issues are seen with that widget.
