pushbutton action

Hi, I have linked a button to this SLOT;it's a toggled button in a exclusive toolbar button;
If my button is down and if I click again on it, the putton is down again (OK), but start SLOT and it executes "emit (setEdit(0));" I don't want this; my button is down still; sould it executes the first part of 'if'? Thanks

Code:

---

void MainForm::zoomingIn( bool pressed )
{
	if (pressed) {
		printf("zoomIN\n");
		emit (setEdit(3));
	}
	else {
		emit (setEdit(0));
	}
}

What signal did you connect it to?

the signal connected to this SLOT is toggled(bool).

You should probably try with stateChanged(int) signal. This will not trigger the slot if you click on an already depressed button. I guess toggled() shouldn't be emitted too, but looks like it is...

sorry, but this signal is from Designer; and the possiblity are: toggled(bool) and activated()....??

I have a stateChanged(int) signal in Designer. You're trying to connect to a slot taking a bool parameter, so Designer hid signals which don't match the signature. Change the slot signature and Designer will show you the stateChanged(int) signal.

sorry, I have deleted the SLOT from desinger, but when I choose action zoomIn, in the signal appears only two above; I remember that toggleAction on this action is 'true';
don't I undestand?

The signal surely is there. It's present since Qt 3.0 so it's not the matter of version... You can take a look at the docs: QButton::stateChanged(int). Try some other way of connecting the signal or attach the ui file here and I will make that connection for you.

EDIT: What do you mean "action ZoomIn"? You said you were connecting a button, not an action... I am talking about connecting the button's stateChanged signal to some signal/slot (whatever it is, be it even the action's activated() signal).

sorry, it isn't a button; is an ACTION!!! (changeState(int) signal there is; but ie for spinBox.....)

So maybe it's better to connect to the action group directly?

You could use the selected(QAction*) signal then and act upon the action which was chosen.
