RE:FIXED qt3to4(THANKS)
Message 1 in thread
Thanks a million to everyone who helped.
Justin; after following you to step 6 of the 30,000 foot view, i:
1) converted the .ui files to qt4 using uic3 -convert myform3.ui > myform4.ui
2)transfered all converted files to a new folder (minus the .h and .cpp files generated from the original qt3 .ui files) [note: the .ui.h approach was not used to add custom slots to the qt3 project; inheritance of the form class was used]
3)then i created a new project that was saved in the new folder and added the converted files; new ui_myclass.h files were generated4) i then applied multiple inheritance and went on to step nine; and followed through.
thanks again.
