[Qt-interest] Generating application icons with Windows, Qt 4.7.1 and Visual Studio Addin 1.1.7

[Darryl Hunter]

Hi all,

 

I spent most of yesterday going round in circles trying to fix a problem, so
thought I'd share it (and the solution) with you all.

 

I recently ported my application from building on Windows XP, Qt 4.6.3, to
Windows 7, Qt 4.7.1.  I noticed recently that the application icon no longer
appears in Explorer, or while the application is running.

 

I tried *many* things, of which I won't go in to, but I finally decided to
compare my vcproj file for the two versions.  And there was a very subtle
difference.

 

In the qrc file, the *new* version had the following extra lines:

 
<FileConfiguration

 
Name="Debug|Win32"

 
>

 
<Tool

 
Name="VCCLCompilerTool"

 
UsePrecompiledHeader="0"

 
/>

 
</FileConfiguration>

 
<FileConfiguration

 
Name="Release|Win32"

 
>

 
<Tool

 
Name="VCCLCompilerTool"

 
UsePrecompiledHeader="0"

 
/>

 
</FileConfiguration>

 

When I removed these, delete the .exe, and re-generate the .exe.  The icon
was there!

 

To make things even more confusing, if I put the lines back in, delete the
.exe and re-generate, the icon is still there!  But at least it fixes my
problem (albeit annoyingly).

 

Luckily I don't have to re-generate too frequently.  But if anybody has seen
a similar problem and has a better solution, that'd be great to see!

 

Darryl
