Problems connecting PushButtons

[Randulf]

I im, as you probably will understand, really new to qt.

Im trying to connec a couple of pushbuttons but cant get it to work.
Lets say I have three buttons, now i them with setCheckabel(true), if I click one of the it shuld be checked but when I click another one the that was checked should uncheck and the new one should be checked.
I have tried a couple of diffrent ways but I mostly get the message that slot doesnt exist.
How do I do this?

Have a look at QButtonGroup. It solves your problem.

Thanks!!
Works like a charm : )

This might be also useful for you (complete app attached):



myApp::myApp()
{

setupUi(this);

int count;
QWidget *widget;
QPushButton *button;

count = splitter->count(); // number of buttons in splitter
// splitter is filled with buttons in designer


// connect them all
for(int i=0;i<count;i++)
{
widget = splitter->widget(i);
button = (QPushButton*) widget;
connect( button, SIGNAL( toggled(bool) ), this, SLOT( checkUncheck() ) );
}

}


void myApp::checkUncheck() // slot
{
int count, index;
QObject *obj;
QPushButton *button, *tmpButton;
QWidget *widget;

count = splitter->count();

obj = sender();
button = qobject_cast<QPushButton *>(obj);

index = splitter->indexOf(button);


// if state not checked - return (we just unchecked button)
if (button->isChecked() == false) return;


for(int i=0;i<count;i++)
{
if ( i == index ) continue; // we skip current button

widget = splitter->widget(i);
tmpButton = (QPushButton*) widget;

if (tmpButton->isChecked() == true) tmpButton->setChecked ( false );
}

}


Note: I don't see QButtonGroup in designer (4.2.0-tp1)
