I'm doing the migration of a Swing application. It was a JFrame with a JMenuBar
and panels.
Actually, I've created a Shell, with an embedded Frame containing all the Swing
panels.
I'm going to migrate the JMenuBar in SWT, in order to set it to the Shell. The
problem I have is the use of Actions. In my panels, I have components which use
Swing Action. And in my future SWT MenuBar, I'll have MenuItems which should use
similar actions. For example, the MenuItem "Save" and the JButton "Save" have
the same action.
Do SWT components support Swing actions? Or am I forced to migrate all in SWT?
I hope you'll be able to help me.
Thank you in advance.
Fabrice

Hi Fabrice,
you can easily write a generic SWT SelectionListener which triggers the
actionPerformed() method of your Swing action and attach it to the menu.
The easiest is probably to write an helper method creating the menu item
from the action:
public static MenuItem createMenuItem(Menu parent, int style, final Action
action)
{
MenuItem item = new MenuItem(parent, style);
String name = action.getValue(Action.NAME);
if (name!=null) item.setText(name);
// ...
// do the same to assign mnemonic, icons, etc...
item.addSelectionListener(new SelectionAdapter()
{
public void widgetSelected(SelectionEvent e)
{
action.actionPerformed(null);
}
});
}
Then use this helper method to create the menu items, instead of using the
constructor.
I hope it helps...

Merci pour ton aide Yannick!
Je vais essayer de mettre en place ce système.
