QLabel not resize in setPixmap()

Is there a way to not modify the size of QLabel when a QPixmap is loaded in it? And the contents were shrinked

Thanks

you can use QPixmap::scaled(int height, int width) to resize your pixmap and then set it to the QLabel.

It works, but now the widget dont resize. I want to strecht it with the dialog

The label must be inside a layout which you would then set as dialogs layout. In designer, you can select the top level layout for the dialog from the context menu of the dialogs background.
