class. This constructor creates a menu item that serves as a separator.
|
static |
Returns the symbol of the checked bitmap.
|
protectedvirtual |
Computes the item size.
Computes the size of the item using the member function IlvGadgetItem::computeRects
, which specifies the location of the label and picture parts. If you want to change the item size, you can override this member function in a subclass.
width | The returned item width. |
height | The returned item height. |
Reimplemented from IlvGadgetItem.
|
virtual |
Deselects the item.
The default implementation deselects and redraws the item, then it calls the holder method IlvGadgetItemHolder::itemDeSelected
.
Reimplemented from IlvGadgetItem.
Suppresses the IlvPopupMenu
associated with the menu item.
destroy | A Boolean value specifying whether the suppressed pop-up menu should be destroyed. |
|
virtual |
Is called to draw the item label.
You can override this method to modify the way the item is drawn.

, that should be used in combination with the accelerator key to invoke the menu item callback (see IlvEvent::modifiers
). const char* IlvMenuItem::getAcceleratorText | ( | ) | const |
Returns the text describing the accelerator. This text appears to the right of the menu item.
IlvPopupMenu
.
|
virtual |
Returns the bitmap mask of the item.
The bitmap mask lets you know which bitmap indexes the item is handling. If the ith bit of the return value is set, it means that the item uses the bitmap of index i
. You can get the associated symbol using the static member function GetItemBitmapSymbol
.

if the menu item is checked. In this case, if the menu item is part of an IlvPopupMenu
, a small check mark appears to the left side of the menu item. It returns IlFalse
if the menu item is not checked. IlBoolean IlvMenuItem::isRadioToggle | ( | ) | const |
Returns the radio state of the menu item.
