Bug? - Moving QFrame - not working when setVisible(false)

maximus · wrote on 20 Aug 2014, 15:18

I have this code that move a QFrame and show it (working) :

@ frameAchievement->setVisible(true);
QPoint currentPoint = frameAchievement->pos();
frameAchievement->setProperty("pos", QPoint(currentPoint.x()-250, currentPoint.y()));
qDebug() << "FRAME IS NOW AT " << frameAchievement->pos();@

This one doesn't work (widget position is not moved on screen, allthought it printed the correct coordinate on the log) :

@ QPoint currentPoint = frameAchievement->pos();
frameAchievement->setProperty("pos", QPoint(currentPoint.x()-250, currentPoint.y()));
frameAchievement->setVisible(true);
qDebug() << "FRAME IS NOW AT " << frameAchievement->pos();@

I need to set visible my Widget after moving it, or it cause a flashing widget on screen for a brief moment, and I don't want that effect.

So the bug would be, changing the "pos" property is not working when QWidget is not visible.

Thank you

Here is the full code for anyone interested, still haven't figured why I can't move my QFrame...

@void WorkoutDialog::animateAchievement() {

achievementCurrentlyPlaying = true;

///Take achievement from top of queue
Achievement *achievement = queueAchievement.head();
/// change name and icon (64x64)
labelAchievementName->setText(achievement->getName());
labelIcon->setStyleSheet("image: url(" + achievement->getIconPath() + ")");


if (firstTimePlayAchievement) {
    ///TOFIX: widget flash for a second when first appearing
    frameAchievement->setVisible(true);
    QPoint currentPoint = frameAchievement->pos();
    frameAchievement->setProperty("pos", QPoint(currentPoint.x()-250, currentPoint.y()));
}

qDebug() << "FRAME IS NOW AT " <&lt; frameAchievement-&gt;pos();


QPoint currentPoint = frameAchievement->pos();
QPoint bottomRightBeforeAnim = QPoint(currentPoint.x(), currentPoint.y());
QPoint bottomRightAftereAnim = QPoint(bottomRightBeforeAnim.x()+250, bottomRightBeforeAnim.y());

QPropertyAnimation *animationShow = new QPropertyAnimation(frameAchievement, "pos");
animationShow->setDuration(1500);
animationShow->setStartValue(bottomRightBeforeAnim) ;
animationShow->setEndValue(bottomRightAftereAnim) ;
animationShow->start(QAbstractAnimation::DeleteWhenStopped);


firstTimePlayAchievement = false;
timerRemoveAnimation->start(5000);

}@

How my QFrame is created :

@ //// ---------------------- Test Achievement Window --------------------------
frameAchievement = new QFrame(ui->widget_allSpeedo);
frameAchievement->setAttribute(Qt::WA_TransparentForMouseEvents,true);
frameAchievement->setFocusPolicy(Qt::NoFocus);
frameAchievement->setSizePolicy(QSizePolicy::Fixed, QSizePolicy::Fixed);
frameAchievement->setFixedSize(250, 150);
frameAchievement->setObjectName("frameAchievement");
frameAchievement->setStyleSheet("QFrame#frameAchievement { background-color : rgba(1,1,1,240); "
"border: 4px solid gray; }"
"QLabel { color: white; }");

QGridLayout *gridAchievement = new QGridLayout(frameAchievement);

QFont fontBold;
fontBold.setPointSize(10);
fontBold.setBold(true);

labelIcon = new QLabel(frameAchievement);
labelIcon->setMinimumHeight(64);
labelIcon->setMaximumHeight(64);
labelIcon->setSizePolicy(QSizePolicy::Minimum, QSizePolicy::Minimum);
labelIcon->setObjectName("labelIcon");
labelIcon->setStyleSheet("image: url(:/image/icon/trophy)");

QLabel *labelAchievementReceived = new QLabel(frameAchievement);
labelAchievementReceived->setMinimumHeight(20);
labelAchievementReceived->setMaximumHeight(20);
labelAchievementReceived->setSizePolicy(QSizePolicy::Minimum, QSizePolicy::Minimum);
labelAchievementReceived->setAlignment(Qt::AlignBottom | Qt::AlignRight);
labelAchievementReceived->setAttribute(Qt::WA_TransparentForMouseEvents,true);
labelAchievementReceived->setText(tr("New Achievement!"));
labelAchievementReceived->setFont(fontBold);

labelAchievementName = new QLabel(frameAchievement);
labelAchievementName->setMinimumHeight(20);
labelAchievementName->setMaximumHeight(20);
labelAchievementName->setMaximumWidth(400);
labelAchievementName->setSizePolicy(QSizePolicy::Minimum, QSizePolicy::Minimum);
labelAchievementName->setAlignment(Qt::AlignBottom | Qt::AlignRight);
labelAchievementName->setAttribute(Qt::WA_TransparentForMouseEvents,true);
labelAchievementName->setText(tr("Name here!"));
labelAchievementName->setFont(fontBold);


gridAchievement->addWidget(labelIcon, 0, 0, 2, 1);
gridAchievement->addWidget(labelAchievementReceived, 0, 1);
gridAchievement->addWidget(labelAchievementName, 1, 1);


QGridLayout *glayout = static_cast<QGridLayout*>( ui->widget_allSpeedo->layout()  );
glayout->addWidget(frameAchievement, 0, 0, 0, 0);

frameAchievement->setAttribute(Qt::WA_TransparentForMouseEvents,true);


timerRemoveAnimation = new QTimer(this);
timerAnimationCompleted = new QTimer(this);
connect (timerRemoveAnimation, SIGNAL(timeout()), this, SLOT(removeAchievementAnimation()) );
connect (timerAnimationCompleted, SIGNAL(timeout()), this, SLOT(lastAchievementAnimationDone()) );
achievementCurrentlyPlaying = false;
firstTimePlayAchievement = true;
/// Hide achievement window /// Not working to move position manually here..
//    frameAchievement->setVisible(true);
//    QPoint currentPoint = frameAchievement->pos();
//    frameAchievement->setProperty("pos", QPoint(currentPoint.x()-250, currentPoint.y()));
frameAchievement->setVisible(false);
