gtkWidgetGetChildRequisition: gtkWidgetGetChildRequisition
Description
This function is only for use in widget implementations. Obtains
widget->requisition, unless someone has forced a particular
geometry on the widget (e.g. with gtkWidgetSetSizeRequest),
in which case it returns that geometry instead of the widget's
requisition.Usage
gtkWidgetGetChildRequisition(object)
Value
A list containing the following elements:
requisition- a
GtkRequisition to be filled in. [ out ]
Details
This function differs from gtkWidgetSizeRequest in that
it retrieves the last size request value from widget->requisition,
while gtkWidgetSizeRequest actually calls the "size_request" method
on widget to compute the size request and fill in widget->requisition,
and only then returns widget->requisition.
Because this function does not call the "size_request" method, it
can only be used when you know that widget->requisition is
up-to-date, that is, gtkWidgetSizeRequest has been called
since the last time a resize was queued. In general, only container
implementations have this information; applications should use
gtkWidgetSizeRequest.
