It exists two kind of methods, corresponding to different needs : | |||

Let us explain it with the following example where we will have a File Menu with sub items to Load or Save a file. | |||
Using <font color=#4169E1>setShortcut()</font> will allow to replace the mouse clicks as is: | |||
* '''ALT+F''' to access to the File Menu | |||
* '''ALT+L''' to access to the Load item | |||
* '''ALT+S''' to access to the Save item | |||
So, to load a file, you will have to type '''ALT+F''' then '''ALT+L''' (as you would have been to click two times using the mouse). | |||
Using <font color=#4169E1>setAccelerator()</font> will allow to access directly to a functionnality (it is actually a shortcut): | |||

It exists two kind of methods, corresponding to different needs :
- setShortcut(), useful to replace a mouse click
- setAccelerator(), used to directly go to a functionnality
Let us explain it with the following example where we will have a File Menu with sub items to Load or Save a file.
Using setShortcut() will allow to replace the mouse clicks as is:
- ALT+F to access to the File Menu
- ALT+L to access to the Load item
- ALT+S to access to the Save item
So, to load a file, you will have to type ALT+F then ALT+L (as you would have been to click two times using the mouse).
Using setAccelerator() will allow to access directly to a functionnality (it is actually a shortcut):
- CTRL+L to access directly to the Load item
- CTRL+S to access directly to the Save item
Here is how to proceed ...
// FileMenu initialization
fileMenu = new GMenu("File");
fileMenu.getJMenu().setMnemonic(KeyEvent.VK_F); // ALT+F to access to this menu
// Moad Item initialization
itemLoad = new GMenuItem("Load ...");
// ALT+L to access to it when File menu is active
itemLoad.setShortcut(KeyEvent.VK_L);
// CTRL+L to access directly to it
itemLoad.setAccelerator(KeyEvent.VK_L, ActionEvent.CTRL_MASK);
fileMenu.add(itemLoad);
itemSave = new GMenuItem("Save ...");
// ALT+S to access to it when File menu is active
itemSave.setShortCut(KeyEvent.VK_S);
// CTRL+S to access directly to it
itemSave.setAccelerator(KeyEvent.VK_S, ActionEvent.CTRL_MASK);
fileMenu.add(itemSave);
