[Qt-interest] Problem with MFC to Qt migration using qt-vs-addin-1.0.2 in VisualStudio2005

[Vanbrabant Martin]

Thanks Oliver,

Now we're getting close...
The only thing is that the QtGuiClass wizard shows some red text in the
dialog box where I would normally fill out the Class name etc., saying:

"It is impossible to add a QtGuiClass to the current project, as it was not
created using QtVSAddin".

That must be the reason why the "Qt Project Settings" menu item is grayed
out as well (see my original posting).

So basically the question is: how do I make the addin believe that it
created the project...
I already tried by comparing the .vcproj files of a simple project created
with the addin with a simple project created by the MFC app wizard.
I noticed additional include paths, library paths, libs.
I also noticed the VisualStudioProject attribate named "Keyword", which
changes from "Qt4VSv1.0" to "MFCProj"'.
No succes so far...

Martin.

Hi Martin,

as the Add-In is not the same as the Visual Studio Integration there are
a few differences in how things are handled.

In order to easily include a new dialog into your project you can use
Project->Add Class->Qt4GuiClass and edit the given properties as needed
(e.g. QDialog as base class). The Add-In then creates the needed cpp, h
and ui files and sets up the custom build steps. So I think this is the
easiest way to introduce a new dialog :)

Regards
Olli
