Qt C++ Eclipse Integration pb with new C++ class wizard
Message 1 in thread
Hi,
I encountered an error when trying to create a new Qt-based class using the "new C++ class" wizard from the CDT (note: not the Qt Gui class wizard). Steps to reproduce (hopefully) :
open the new C++ class wizard, specify a class name, click "Add" to specify a base class, select QAbstractItemModel, the base class appears correctly in the table, then click "Finish". A dialog appears to confirm the addition of new files in the .pro file, but only the HEADERS section appears. After clicking ok an error message pops up in the C++ class wizard, and the class isn't generated. Only an incomplete .h file is created.
The error log entry is pasted below. Note that the wizard completes fine (including adding the new files to the .pro) if I don't specify the base class.
I use Eclipse 3.2.1 and CDT 3.1.1 on Windows XP 32bits.
Best regards,

Hi,
thanks for reporting that, we can reproduce the behavior (with a slightly different stacktrace).
