gtkWidgetSizeRequest: gtkWidgetSizeRequest
Description
This function is typically used when implementing a GtkContainer
subclass. Obtains the preferred size of a widget. The container
uses this information to arrange its child widgets and decide what
size allocations to give them with gtkWidgetSizeAllocate.Usage
gtkWidgetSizeRequest(object)
Value
A list containing the following elements:
requisition- a
GtkRequisition to be filled in. [ out ]
Details
You can also call this function from an application, with some
caveats. Most notably, getting a size request requires the widget
to be associated with a screen, because font information may be
needed. Multihead-aware applications should keep this in mind.
Also remember that the size request is not necessarily the size
a widget will actually be allocated.
