[SOLVED]QPushButton Signal connection

[dreamerindia]

Hi all,

Is there is any method to connect the all QPushbuttons used in the project to same slot. instead of writing connect statement for individual QpushButtons?

Instead of,
@ connect(ui->continuousBut,SIGNAL(pressed()),this,SLOT(Beep()));
connect(ui->continuousBut,SIGNAL(released()),this,SLOT(Mute()));

connect(ui->GateBut,SIGNAL(pressed()),this,SLOT(Beep()));
connect(ui->GateBut,SIGNAL(released()),this,SLOT(Mute()));

connect(ui->singleBut,SIGNAL(pressed()),this,SLOT(Beep()));
connect(ui->singleBut,SIGNAL(released()),this,SLOT(Mute()));

connect(ui->burstBut,SIGNAL(pressed()),this,SLOT(Beep()));
connect(ui->burstBut,SIGNAL(released()),this,SLOT(Mute()));

connect(ui->MANBut,SIGNAL(pressed()),this,SLOT(Beep()));
connect(ui->MANBut,SIGNAL(released()),this,SLOT(Mute()));

connect(ui->INTBut,SIGNAL(pressed()),this,SLOT(Beep()));
connect(ui->INTBut,SIGNAL(released()),this,SLOT(Mute()));

connect(ui->EXTBut,SIGNAL(pressed()),this,SLOT(Beep()));
connect(ui->EXTBut,SIGNAL(released()),this,SLOT(Mute()));@

something like,

@connect(ui->QPushButton,SIGNAL(pressed()),this,SLOT(Beep()));
connect(ui->QPushButton,SIGNAL(released()),this,SLOT(Mute()));@

there is an "auto connect feature":http://qt-project.org/doc/qt-4.8/qmetaobject.html#connectSlotsByName in Qt, which connects objects with a slot automatically.
But i requires to set the "object name":http://qt-project.org/doc/qt-4.8/qobject.html#objectName-prop. But i don't know if this is possible when using ui-Files (never used them yet)... If it's possible to set a different QObject-objectname than the object name in the ui file to identify the object then you can try using this method.

... or create "QButtonGroup":http://qt-project.org/doc/qt-5.0/qtwidgets/qbuttongroup.html, add all buttons in it and connect one of the QButtonGroup::buttonClicked signal to your slot

Hi,

There's also findChildren and you loop over the button list to connect them. That is unless you have other push buttons on the same UI. In this case you should give a name to these buttons to use findChildren

You can do this aslo:
@void ButtonGroup1Slot()
{
if(sender()->objectName().contains("Button1"))
{
//do this and so on for other buttons
}
//perform similar operations here
}@
