void Wt::WPopupMenuItem::load | ( | ) | [virtual] |
Loads content just before the widget is used.
When the widget is inserted in the widget hierarchy, this method is called. Widgets that get inserted in the widget hierarchy will be rendered. Visible widgets are rendered immediately, and invisible widgets in the back-ground (or not for a plain HTML session). This method is called when the widget is directly or indirectly inserted into the widget tree.
The default implementation simply propagates the load signal to its children. You may want to override this method to delay loading of resource-intensive contents.
Reimplemented from Wt::WCompositeWidget.
