vgui_tableau_sptr const & new_child

) [virtual, inherited]

Called whenever a child of this tableau is about to be forcibly replaced.
This method is called when some part of the program (typically the parent_child_link mechanism) is about to forcibly replace a child of this tableau. The canonical reason to override this is in order to invalidate caches.
Definition at line 301 of file vgui_tableau.cxx.

void vgui_tableau::post_idle_request ( ) [virtual, inherited]

Post an idle request event.
The fact that this is virtual does not imply that you should go and override it.
Posting an idle event request means that your tableau has some idle processing that it'd like to do. This means that your tableau will continue to receive vgui_IDLE events until the event handler returns false (i.e. all idle processing is complete). The idle event handler should return false when it has no idle processing, or has completed its idle processing. It may return true if has only partially completed its idle processing; in this case, it will receive more idle event to allow it to complete processing.
Reimplemented in vgui_adaptor_tableau.
Definition at line 234 of file vgui_tableau.cxx.

void vgui_tableau::post_message ( char const * ,

void const *

Post a overlay-redraw event.
The fact that this is virtual does not imply that you should go and override it.
Reimplemented in vgui_adaptor_tableau.
Definition at line 224 of file vgui_tableau.cxx.

void vgui_tableau::post_redraw ( ) [virtual, inherited]
