Exchange images at the same position
in earlier days (VCL, C# Windows Forms) when I had to toggle between two images at the same location in a window I placed those two images at the very same location and toggled their visibility.
How would I achieve such behaviour with Qt?
I just started programming with Qt and I cannot find any simple way :-( When I have a label with a pixmap, I cannot put two of them to the same position. At least the layout system in Qt Designer doesn't seem to allow this.
Even if I would think about resetting the pixmap (what would be the best way then?) I wonder how one can use overlapping elements.
Have a look at QStackedWidget
You could use
And just use one label, no overlapping
If you want overlapping, a QGridLayout let you to have element on top of another.
Just insert them in the same row, column and toggle visibility of the one you need
For "overlapping" rather than the QGridLayout, a QStackedLayout or as suggested by by @matze42 a QStackedWidget it the way to go.
Thank you all - QStackedWidget helps!
