Menu shortcuts, also known as menu accelerators and command key equivalents, rarely accelerate anything. Nonetheless users often mistakenly think they do, and so a salable application needs them.
The java.awt.MenuShortcut
class represents such a
keyboard accelerator. This class has two constructors:
public MenuShortcut(int key)
public MenuShortcut(int key, boolean useShiftModifier)
In both cases the key
argument is the raw keycode that
will be used to invoke this menu item.
If useShiftModifier
is true
, then the
shift key must be held down for this shortcut to be activated.
useShiftModifier
is false
by default.
To add an accelerator key to a menu item, pass a
MenuShortcut
to the item's setShortcut()
method. For example,
MenuShortcut pShortcut = new MenuShortcut(KeyEvent.VK_P);
MenuItem mi = new MenuItem("Print...");
mi.setShortcut(pShortcut);
You can also just pass the shortcut to the MenuItem()
constructor like this:
MenuShortcut pShortcut = new MenuShortcut(KeyEvent.VK_P);
MenuItem mi = new MenuItem("Print...", pShortcut);
