Hello,

is there any possibility to perform an action when an user changes the
selected tabitem?

I want to display a message if the user doesn't fill out all fields. If
he doesn't then he should stay on the active tab, otherwise he "is
allowed" to change it!

can anybody help me??

thx

tabFolder.addSelectionListener(new SelectionListener() {
public void widgetSelected(SelectionEvent event) {
switch (tf.getSelectionIndex()) {
case 0:
// first tab was clicked
break;
}
}
}

You get the idea.

thank you emil for your answer,

but i have got the problem that i cannot _stop_ the event.
the idea was that the code should check whether the user filled out the
fields correctly or not. if he doesn't do it correctly then he should
stay on the actual tab. But how can I perform this "stopping action"?

"event.doit = false;" doesn't work!

thx

Can't you just re-select the active tab when they try to click another tab?
