i have a Qt project.i used Qt creator as IDE.so in Qt creator i written several ui files. The project is so big and i had used cmake in that project.
now i have switched to KDevelop. but my ui files are shown as XML file.is there a Qt Designer plugin for KDevelop?or if not what can i do to edit my ui files.i want to define signals slots for buttons and ....[what ever i can do with qt creator!]
thank you so much and i apologize for my English.

There is no plugin, but you can simply open your .ui files with the stand-alone "designer" application, which is exactly the same widget you have in QtCreator as well. Right-click -> Open WIth -> Designer should do it, or "designer foo.ui" from console.
