Detailed Description

Tableau for rendering text.

Each piece of text is associated with an integer handle through which it can be retrieved, moved about, changed or removed.

This tableau will not display any text unless you have compiled with GLUT.

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.

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. **

Reimplemented in vgui_active_tableau, vgui_clear_tableau, and vgui_satellite_tableau_t< object, data >.

Definition at line 316 of file vgui_tableau.cxx.

Definition at line 327 of file vgui_tableau.cxx.

void vgui_tableau::post_message ( char const *  msg,
void const *  data 
) [virtual, inherited]

Post a message 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 205 of file vgui_tableau.cxx.

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

Post a draw 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 215 of file vgui_tableau.cxx.

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

Post a overlay-redraw event.

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 225 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.

Reimplemented in vgui_adaptor_tableau.

Definition at line 235 of file vgui_tableau.cxx.

bool vgui_tableau::get_bounding_box ( float  low[3],
float  high[3] 
) const [virtual, inherited]

Get the bounding box of this tableau.

Return the bounding box of this tableau.

If infinite in extent, or nothing is drawn, or you can't be bothered to implement it, return false. const. if you need to cache, cast away const.

If infinite in extent, or nothing is drawn, or you can't be bothered to implement it, return false.

Reimplemented in vgui_composite_tableau, vgui_image_tableau, vgui_roi_tableau, and vgui_wrapper_tableau.

bool vgui_tableau::idle (  )  [virtual, inherited]

Called when the application is otherwise idle.

Override if you want to do idle processing. Return false once your idle processing is complete, or if you have no need for more idle processing. Return true if you need more idle processing time.

void vgui_tableau::ref (  )  const [inherited]

Increase the reference count by one (for smart pointers).

void vgui_tableau::unref (  )  const [inherited]

Decrease the reference count by one (for smart pointers).

Decrease the reference count by one (for smart-pointers).
