Re: [Qt-creator] Editing widget rendering problems
It sounds like you have some video buffer corruption, try restarting your windowing system. I haven't used Linux in a while, but it used to be that you could just log out and log back in to do this. Is that still true?

[Qt-creator] Wrong path when using external editor
Qt Creator 1.3.0 under Windows XP Funny things happen if I try to open a file in the configured external editor: If the editor is the default Notepad, the expected code appears in Notepad, but if I select save-as, I immediately get Common Dialog error (0x3002). This does not happen if Notepad is run outside of Qt Creator. If the editor is emacs, the path emacs sees is .../Qt/2009.05/qt/projects/projectname/sourcefilename. I don't even have a projects directory under the Qt install tree; projects are on a different partition. Notepad is probably not getting the right path either. Open is defaulting to .../Qt/2009.05/qt. I have no desire to use Notepad as a code editor, but sometimes I do want to do something that the Qt Creator doesn't support. ___ Qt-creator mailing list Qt-creator@trolltech.com http://lists.trolltech.com/mailman/listinfo/qt-creator

It's a plugin system.

[Qt-creator] other languages syntax highlight support
Hi, is there a obvious way to add syntax highlight to qt-creator, for other languages? In my case, I would like to use qt-creator to edit my glsl files. Is it possible to do this through a config/rules file? Thanks Paulo ___ Qt-creator mailing list Qt-creator@trolltech.com http://lists.trolltech.com/mailman/listinfo/qt-creator
[Qt-creator] gcov support?
Today I discovered there is a code-coverage tool for gcc called gcov.

Re: [Qt-creator] Add new project templates
i do agree too! i also think of class templates and stuff like that. from time to time i'd really like to add an extra class template besides from QObject or QWidget. it can help speed up your workflow if you're deriving classes from abstract ones. so all the pure virtual functions could be preimplementet in the template. 2009/12/18 Porfírio Ribeiro > I agree with you, i also use QtCreator for some non Qt projects! > > 2009/12/16 Tiago Correia > >> Hi, >> >> I'd like to add new templates for projects, when creating a new project. >> How can i do this? >> >> A project that is very useful for me is, for creating a simple C or C++ >> program, that doesn't use Qt. >> I've always to edit the pro file.
