Associate my QT application with video/image files in Inno Setup

Question

I have developed QT application to view image/videos. I am deploying the application using windeployqt and have created setup.exe using Inno Setup tool.

I have already implemented code to show up image when opened through my app.

Now I want my application name to show up in "Open with list" whenever I click on image or video.

Has anyone idea how to achieve this?

Based on How to Include an Application in the Open With Dialog Box – you have to create a registry values like these:

[HKEY_CLASSES_ROOT\.cpp\OpenWithProgids]
"VisualStudio.cpp.14.0"=""

[HKEY_CLASSES_ROOT\VisualStudio.cpp.14.0]
@="C++ Source"

[HKEY_CLASSES_ROOT\VisualStudio.cpp.14.0\DefaultIcon]
@="C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\vcpackages\\VCProject.dll,2"

[HKEY_CLASSES_ROOT\VisualStudio.cpp.14.0\shell]

[HKEY_CLASSES_ROOT\VisualStudio.cpp.14.0\shell\Open]

[HKEY_CLASSES_ROOT\VisualStudio.cpp.14.0\shell\Open\Command]
@="\"C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\Common7\\IDE\\devenv.exe\" /dde"
