I’m actually doing this in Photon 1.14 but thought that the same might apply
in Photon 2.0
I’m attempting to create a widget and then change it’s size programatically.
Problem is when I send a PtSetResources(…) Nothing seems to happen.
Actually when I click in the area which is supposed to be the new window
size, the window is selected. But graphically it’s not shown. Can anyone
give me some help? Here is what I’m doing:
