Parameters: handle The handle that represents a pointer to a native resource.

getType

Parameters: listener The object that is to no longer receive menuitem events.

setLeftJustified

public void setLeftJustified()

MenuItem's are left justified by default. Use this method to change a MenuItem from right justified back to left justified.

Sets whether the menu item appears to the right side of the menu bar. This was traditionally done for the Help menu, but is now considered a bad idea. (If the widget layout is reversed for a right to left language like Hebrew or Arabic, right-justified menu items appear at the left).

Sets the submenu, or changes it.

Parameters: submenu The submenu.
