Detailed Description
Tableau to blend two images.
To use this tableau make a vgui_image_tableau containing one of the images to blend and a vgui_blender_tableau containing the other. Put them both in a vgui_composite_tableau. Set alpha to be less than one to see the blended image.

| bool vgui_tableau::add_child | ( | vgui_tableau_sptr const & | ) | [virtual, inherited] |
Add the given tableau to the list of child tableaux.
Virtual overridden by consenting parents.
Reimplemented in vgui_composite_tableau, vgui_selector_tableau, vgui_deck_tableau, and vgui_wrapper_tableau.

| void vgui_tableau::add_popup | ( | vgui_menu & | ) | [virtual, inherited] |
Add the given menu to the popup menu for the tableau.
Add given menu to the tableau popup menu.
This method is for tableaux to implement if they want to _add_ some items to the popup menu. They can assign to or clear 'menu', but that is not recommended as it would remove what other tableaux put there. The recommended usage is to .add() items or to .include() another menu.
** This is an interface method. it abstracts a behaviour. **

Called whenever a child of this tableau is about to be forcibly replaced.
Called when a child of this tableau is 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 302 of file vgui_tableau.cxx.
| void vgui_tableau::post_idle_request | ( | void | ) | [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.
