--- Comment #12 from Andi Sardina <andysardin...@gmail.com> --- Postix, I notice it, but the problem is that the function to open the file is in the part (KParts::ReadWritePart), which is created and added to the tab widget before know if the file will be opened successfully or not. Maybe there is a way to do update the UI after. I am trying to write an autotest right now, and it will take me a bit because I haven't written a test in Qt before. But after I finish this, I will try to solve it! -- You are receiving this mail because: You are the assignee for the bug.
