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

[Darryl Hunter]

Thanks for the suggestion.  I had deleted the “Release” directory, re-generated from QMake, and even built again from a fresh checkout (in another area), still with no success.

 

I have since managed to find out that the deleting the content didn’t make an impact – the re-opening of the vcproj file did????  So now from a fresh checkout, I can open my SUBDIRS .pro file, do a build, close the solution, open the .sln file, delete the generated .exe, and do a Make, and it’s OK.  Weird….

I'm betting you just didn't do a "rebuild all". I get burned by it sometimes. 

Remember "make" isn't perfect - it just uses timestamps, not hashes.

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
