Make image bigger, when the mouse is over QLabel

[Globulus]

Hi, everyone!

So, how can I make QLabel widget,that contains image, save its centr,
when I change geometry.(just making image bigger, when the mouse is over QLabel
from 64x64 to 128x128)


Thanks for your help!

This is the code, that I use:

void MainWindow::label_hover()
{
    QPropertyAnimation *animation = new QPropertyAnimation(ui->label, "geometry");
    animation->setDuration(600);
    animation->setStartValue(QRect(390,70, 64, 64));
    animation->setEndValue(QRect(390, 70, 128, 128)); 
    animation->setEasingCurve(QEasingCurve::OutCubic);
    animation->start();   
}

void MainWindow::label_hover()
{
    QPropertyAnimation *animation = new QPropertyAnimation(ui->label, "geometry");
    animation->setDuration(600);
    animation->setStartValue(QRect(390,70, 64, 64));
    animation->setEndValue(QRect(390, 70, 128, 128)); 
    animation->setEasingCurve(QEasingCurve::OutCubic);
    animation->start();   
}

Hi,

I would suggest having a extended class of QLabel and override mouse events (i.e. mouse enter and mouse leave) and override paint event for more advanced effects like gradually increasing or decreasing the size.
