    Hi,

    Hello is it possible to resize a QPixmap without auto rescale of the height ?

    I tryed many way but nothin seems to work.

    If not i will have to load every single picture modified in paint or something like that...

    Of course i spent time searching on the web but nobody asked this question already.
    I'm pretty new in Qt Framework but i will learn as fast as possible.
    Thanks in advance

      Hi and welcome to devnet,

      Do you mean QPixmap::scaled using Qt::IgnoreAspectRatio ?

        Ho yeah, thanks alot.
        I did not check the scaled method, i was trying something like resize or setGeometry.
        It work fine !

        Here is how look my slot now:

        void MainWindow::resizeRessort(int resizeWidth)
        {
            int newWidth=(int)(((resizeWidth+1)/100.0)*myWidth);
            QSize myRessortSize(newWidth,myHeigth);
        
            QPixmap myNewRessort =myRessort->scaled(myRessortSize,Qt::IgnoreAspectRatio,Qt::SmoothTransformation);
        
        
            myLabel->setPixmap(myNewRessort);
        }
        

        Hope it can help

        Thanks
