Hi,
I'm using Qt Creator 1.3.0 on Windows XP.
I'm developing custom widgets in Creator, but as many other people have found, these widgets don't get imported into the integrated Designer. However, my widgets do work when Designer is run independently of Creator.
The initial problem was due to Creator being shipped as a Visual Studio build, so I hunted on Google for a solution, and found this stackoverflow article. I have now built Qt Creator using MinGW, as mentioned in StackOverflow question 1751107.
I've made progress, as now when I navigate in Qt Creator to Tools->Form Editor->About QT Designer plugins, I can see my plugin at
C:/Qt/2009.05/qt/plugins/designer/iconeditorplugin.dll
but it is followed by this error:
The plugin 'C:/Qt/ ... /iconeditorplugin.dll' uses incompatible Qt library. (Cannot mix debug and release libraries.)
I have tried building my widget in both debug and release modes, setting the build configuration both through Creator's Build->Set build configuration menu, and in the project properties page in Creator. I'm now at a loss as to what to do. I hope someone can help.
Thank you for reading,
Jamie.
