Get size of mainwindow and set width and height of a widget

[Kris Revi]

so what i have made is this

void MainWindow::on_pushButtonMaximize_clicked()
{
    QSize size = this->size();

    if(isMaximized() == false)
    {
        showMaximized();
        ui->quickWidget->setGeometry(0, 0, size.width(), size.height());
    }
    else
    {
        showNormal();
        ui->quickWidget->setGeometry(0, 0, 1280, 720);
    }

    qDebug() << "MainWindow Width : " << this->size().width() << "MainWindow Height : " << this->size().height();
}

what im trying todo is on showMaximized i want to set quickWidget to the size of mainwindow and then hard set it back when showNormal is set

but when i press the Maximize button (to maximize the window) i only get the "current" so 1280x720
and when i press the Maximize button again THEN it gets the 1920x1080

im having a huge brainfart over this.... how to fix this?

Use layouts instead.

@Christian-Ehrlicher i cant that is the problem! AFAIK i cant have a layout the way i have setup this

the quickWidget is QML file with an animation background and then i have the frame (QFrame) onTOP of that! when using layout this is not possible AFAIK!

@Kris-Revi According to the picture quickWidget is child of frame_2 (means quickWidget is INSIDE frame_2). So, why can't you have a layout?

[Kris Revi]

@jsulm if i set a layout on frame_2 , frame wont stack onTOP of quickWidget

[Thank You]

@Kris-Revi

```

QRect mainGm = ui->centralwidget->geometry();
ui->yourWidget->setGeometry(mainGm);

Get geometry and set the geometry of children widget
