I have a toolBar with two toolItems (1 and 2), both with radio-style and
SelectionListener(SelectionAdapter)
If I press toolItem1 the code inside the SelectionListener will be executed,
ok.
But if I press toolItem2 the code inside toolItem1s SelectionListener will
also be executed again.
I've tried to remove the SelectionListener of toolItem1 when the end of the
code is reached, but without success. Nothing changes.
Thanks For Your Help.

Radiobuttons are by default grouped. Just check to see which button has the
selection to determine what was clicked, like:
public static void main(String args []) {
Display display = new Display();
Shell shell = new Shell(display, SWT.SHELL_TRIM);
shell.setLayout(new FillLayout());
shell.setSize(150, 150);
// two buttons
final Button a = new Button(shell, SWT.RADIO);
a.setText("A");
a.setData("Button A");
final Button b = new Button(shell, SWT.RADIO);
b.setText("B");
b.setData("Button B");
a.addListener(SWT.Selection, new Listener() {
public void handleEvent(Event event) {
System.err.println("I pressed " + (a.getSelection() ? "a" :
"b"));
}
});
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) display.sleep();
}
display.dispose();
}

Thanks Emil. I added an if(tool_Item.getSelection) to each toolItem Code.
Now it works. Thank You
