\section{\class{wxQueryLayoutInfoEvent}}\label{wxquerylayoutinfoevent}
|
|
|
|
This event is sent when \helpref{wxLayoutAlgorithm}{wxlayoutalgorithm} wishes to get
|
|
the size, orientation and alignment of a window. More precisely, the event is sent
|
|
by the OnCalculateLayout handler which is itself invoked by wxLayoutAlgorithm.
