some problems with qpushbutton->setdisable

gfxx

I use setdisable true/false for "close" mouse event over a button after the User pressed action. I use a delay for renew the condition aver qpushbutton .... my simple code:


void MainWindow::sendPause(bool paGen)
{
        ui->GRun->setDisabled(true);
        if (paGen && (StIsOn1 && StIsRunning1)) {
            qDebug() << "xxxxx1";
            ui->Grun->setChecked(false);
            emit sendInOut(k::cm_pause_gen, true, 0);
        }
        else{
            qDebug() << "xxxxx2";
            ui->GPause->setChecked(false);
        }
        PauseResumeAutocheck();

}

void MainWindow::sendRun(bool paRun)
{
        ui->Grun->setDisabled(true);
        if (paRun && (StIsOn1x && StIsRunning1x)) {
            qDebug() << "xxxxx3";
            ui->GPause->setChecked(false);
            emit sendInOut(k::cm_pause_gen, false, 0);
        }
        else{
            qDebug() << "xxxxx4";
            ui->GRun->setChecked(false);
        }
        PauseResumeAutocheck();

}

void MainWindow::PauseResumeAutocheck()
{
    QTimer::singleShot(1200, [=]{ ui->Grun->setDisabled(false); ui->Gpause->setDisabled(false); qDebug() << "reset Pause Resume";});
}

The two qpushbutton is insert in a qgrouobox, and I set it as Autoexclusive.

The code work not so good (some time the delay is not see) ... any how the event is equally propagated ... for example:

I press GPause -> emit signal is ok
qDebug messages is print
the delay is ok ...
I press GRun -> emit signal is ok
qDebug messages is print
for test I try to press GPause immediately after press GRun -> GPause not change BUT
qDebug messages is print ... ????? Why these?????

I hope someone can suggest my the right process to do these, because this obviuslly is not perfect working.

You use QTimer::singleShot - it is executed every time and you can't stop it from executing. Just use a QTimer object to have more control over it.
