I’m writing a “custom makefile” project using QtCreator and I want to delete a file of my project, so, I select the file in the tree view, press the right click and the “delete” option is disabled and I did not find any way of enable it.
My environment: QtCreator 1.2.1 on SnowLeopard:

Thanks in advance,
Ernesto
By the way, I downloaded and installed Qt creator 1.3 beta for Mac OS X and deleting files is working properly.
