@roiredxsoto
How did you fix the ‘open with’ problem? I am facing the same problem (UBLViewer)
I looked into the reply by @phw and I downloaded your package that you made for CudaText, where I see that you made a resource file with the attributes QT:QPA_FLAGS.
I’ve made a rdef-file (and .rsrc file) based on your example, but how do I incorperate this into pascal code (freepascal or lazarus)
I am using libQt5Pas (1.2.9) and Haiku 64bit (and a bit lost)
FOUND IT: Seems I needed to add the attributes using xres
