Member Function Documentation

void IlvAbstractMenu::addHighlightCallback ( IlvGraphicCallback  callback,
IlBoolean  submenus = IlTrue 
)

Adds a "Highlight" callback to the menu.

Adds the "Highlight" callback specified by callback to the menu. If submenus is set to IlTrue, the same callback is added to the submenus. When the callback is invoked, its IlAny parameter can be cast in a pointer to an IlShort. This IlShort indicates the position of the currently highlighted menu item or is set to -1 if no menu item is highlighted. See the example in the setHighlightCallback() method above. A "Highlight" callback is invoked when an item of the menu is highlighted.

Parameters
callbackA pointer to the callback.
submenusSpecifies whether the callback should be propagated to the submenus.
See Also
setHighlightCallback().
void IlvAbstractMenu::addHighlightCallback ( const IlSymbol callbackName,
IlBoolean  submenus = IlTrue 
)

Adds a named "Highlight" callback to the menu.

Adds the highlight callback specified by callbackName to the menu. If submenus is set to IlTrue, the same callback name is added to the submenus. When the callback is invoked, its IlAny parameter can be cast in a pointer to an IlShort. This IlShort indicates the position of the currently highlighted menu item or is set to -1 if no menu item is highlighted. See the example in the setHighlightCallback() method above. A "Highlight" callback is invoked when a menu item is highlighted.

Parameters
callbackNameThe name of the callback.
submenusSpecifies whether the callback should be propagated to the submenus.
See Also
setHighlightCallback().
virtual IlvGadgetItem* IlvAbstractMenu::createItem ( const char *  label,
IlvGraphic graphic = 0,
IlvBitmap bitmap = 0,
IlvBitmap selbitmap = 0,
IlBoolean  copy = IlTrue 
) const
virtual

Returns a new gadget item.

You can override this member function in a subclass to create your own items.

Parameters
labelThe item label.
graphicThe IlvGraphic object representing the picture associated with the item.
bitmapThe IlvBitmap object representing the picture associated with the item.
selbitmapThe IlvBitmap object representing the picture of the item when it is selected.
copySpecifies whether a label should be copied. If the value is IlFalse, then you must allocate some memory for the label because in any case the label characters are deleted from the memory by the IlvGadgetItem.
Note
If both the second and third parameters are not 0, only the second parameter is used.
Returns
The created gadget item.
