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::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.

void vgui_tableau::get_popup ( vgui_popup_params const &  params,

Gets popup menu for this tableau.

If recurse is, true, recursively add the popup menus for children and children's children etc.

** this is a mixin method. it does some work for you. **

Reimplemented in vgui_deck_tableau, vgui_image_tableau, vgui_poly_tableau, vgui_shell_tableau, vgui_tview_launcher_tableau, and vgui_tview_tableau.

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::draw (  )  [virtual, inherited]

Called by default handle when it receives a draw event.

Reimplemented in vgui_function_tableau.

Definition at line 176 of file vgui_tableau.cxx.

bool vgui_tableau::motion ( int  x,
int  y 
) [virtual, inherited]

Called by handle when it receives a mouse motion event.

Called by default handle when it receives a mouse motion event.

Reimplemented in vgui_displaylist2D_tableau, vgui_function_tableau, and vgui_listmanager2D_tableau.

Definition at line 146 of file vgui_tableau.cxx.

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.

Definition at line 185 of file vgui_tableau.cxx.

void vgui_tableau::ref (  )  const [inherited]

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

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

"const" is for convenience, it is cast away internally.

Definition at line 79 of file vgui_tableau.cxx.

void vgui_tableau::unref (  )  const [inherited]

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

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

"const" is for convenience, it is cast away internally. If the reference count reaches zero then delete the object.

If the reference count reaches zero then delete the object.
