QToggleButton

[franco.amato]

Hi I need a QTogggleButton but seems QT doesn't has such widget.
In my case I need to load 2 different icons. I would implement a play/pause button so I need to toggle between the > and || images.
How can I do?

Best Regards,
Franco

you can use a tool button and implement something like so:

void MainWindow::playPause()
{
    QIcon icon1;
    QIcon icon2;
    icon1.addFile(QString::fromUtf8(":icons/icons/media_playback_pause"), QSize(),QIcon::Normal, QIcon::On);
    icon2.addFile(QString::fromUtf8(":icons/icons/media_playback_start"), QSize(),QIcon::Normal, QIcon::On);
    if(mediaObject->state() == Phonon::StoppedState){
        mediaObject->play();
    } else {
        if(mediaObject->state() == Phonon::PlayingState){
            mediaObject->pause();
            ui->toolButton_4->setIcon(icon2);
            ui->label_2->setText("Paused");
        } else {
            if(mediaObject->state() == Phonon::PausedState){
                mediaObject->play();
                ui->label_2->setText("Playing");
                ui->toolButton_4->setIcon(icon1);
                }
        }
    }
}
 
void MainWindow::stop()
{
    QIcon icon;
    icon.addFile(QString::fromUtf8(":icons/icons/media_playback_start"), QSize(),QIcon::Normal, QIcon::On);
    mediaObject->stop();
    ui->toolButton_4->setIcon(icon);
    ui->label_2->setText("Stopped");
    ui->label->setText("00:00");
}

void MainWindow::playPause()
{
    QIcon icon1;
    QIcon icon2;
    icon1.addFile(QString::fromUtf8(":icons/icons/media_playback_pause"), QSize(),QIcon::Normal, QIcon::On);
    icon2.addFile(QString::fromUtf8(":icons/icons/media_playback_start"), QSize(),QIcon::Normal, QIcon::On);
    if(mediaObject->state() == Phonon::StoppedState){
        mediaObject->play();
    } else {
        if(mediaObject->state() == Phonon::PlayingState){
            mediaObject->pause();
            ui->toolButton_4->setIcon(icon2);
            ui->label_2->setText("Paused");
        } else {
            if(mediaObject->state() == Phonon::PausedState){
                mediaObject->play();
                ui->label_2->setText("Playing");
                ui->toolButton_4->setIcon(icon1);
                }
        }
    }
}

void MainWindow::stop()
{
    QIcon icon;
    icon.addFile(QString::fromUtf8(":icons/icons/media_playback_start"), QSize(),QIcon::Normal, QIcon::On);
    mediaObject->stop();
    ui->toolButton_4->setIcon(icon);
    ui->label_2->setText("Stopped");
    ui->label->setText("00:00");
}

hope it helps

or you can do it easily in Qt Creator by assigning different bitmaps for the different states

and make the button checkable. The different bitmaps are stored in a qrc file.
