QButtonGroup buttonClicked signal/slot problem

[davidthewatson]

Hello,

I'm connecting a QButtonGroup buttonClicked(int) signal to a slot in my MainWindow class as follows:

QObject::connect( leftButtonGroup, SIGNAL(buttonClicked(int)), this, SLOT(onLeftButtonClicked(int)));

The connect works and I get the event. However, when my slot gets the event, id is always -1, no matter which button I press.

The slot looks like:

void MainWindow::onLeftButtonClicked(int id)
{
switch(id)
...

I have 8 buttons in the group. Any idea why I don't get the proper value?

I'm using Qt 4.3.4 on Windows XP SP2.

Thanks,
David

have u called setId() for every button?

[davidthewatson]

Yes, this solved my problem. Thanks!

I guess what I don't understand is why QButtonGroup doesn't just init the id with a static incremementer automatically such that you'd get the id's in the order they were added without having to call setId.

lets not expect Qt to do everything for us..there has to be a reason we get paid for what we do :)
