GUI design doesn't update when changed in Qt Creator
I am having exactly the same sort of problem.
I created a gui with a spinbutton with the default properties (maxvalue = 100).
After compiling and running the application, I went back to change the property to maxvalue = 30000. The change appeared correctly in the preview but when I recompiled and ran the application, the old limit still applied.
I tried a clean build, deleting the entire build directory, renaming ui_mainwindow.h-- nothing would get the changed properties to apply to the executable.
Finally I rebuilt the application in VS2017, which fixed the problem and when I went back to Qt creator and rebuilt the executable there the problem was also resolved.
There ought to be a better way to force the mainwindow form to "recompile" in Qt Creator but I can't find it. What am I missing?
make very, very sure that No build files somehow ended up in project folder.
like moc_xx and ui_xxx.
That gives such odd behavior.
And just to add to @mrjj, no Makefiles.
These kind of files should only exist in the build folder. If you have a duplicate in the project folder, it will drive you crazy.
