Help with QButtonBox

ningu

Hi,

I'm new to Qt.

I have a QDialog with a QButtonBox that has a Save, Cancel and Open buttons. I've read the documentation for the QButtonBox, but I just can't figure out how to manage the buttons events. I know I can manage the accepted() and cancelled() events, but since Open and Save buttons are both 'accepting' I don't know where to put the code for each one of them. Any pointers?

I've been searching but I just can't find any answers to this problem. I'm stuck and I would very much appreciate your help.

Thanks.

You can use the signal :
void clicked ( QAbstractButton * button )
to know what button you activate by clicking

Thanks. I tried that, but I had problems figuring out how to know what button sent the signal. I finally found button->text() to be the closest hit, but I'm not sure if that's the best way to do it. Is there a better (correct) way to find out about the sender?

nikoko

Use sender () function which return which object send the signal.
Example :
@
void xxxx:mySlot ()
{
QPushButton * pb = dynamic_cast <QPushButton *>( sender ());

if (pb == buttonOk)
...
}

Hi,

You can use the "clicked signal":http://qt-project.org/doc/qt-4.8/qdialogbuttonbox.html#clicked signal from QDialogButtonBox:
@
void xxxx::onClickedButtonSignal(QAbstractButton * button)
{
QDialogButtonBox::StandardButton stdButton = _dialogButtonBox.standardButton(button);
switch (stdButton) {
case QDialogButtonBox::Ok:
...
break;
// etc...
}
}

_dialogButtonBox was giving me an error because it's not the name of my instance and took me a while to find out that the right code for me:
@QDialogButtonBox::StandardButton stdButton = ui->buttonBox->standardButton(button);@
As I told you, I'm new to Qt. But now I got it running. Thank you very much SGaist!

@Nikoko: Thanks for your suggestion. I think I get what you mean, but SGaist's solution is exactly what I was looking for.
