Re: [Interest] Launch Qt Desktop Application(Windows) by clicking custom file

You just need to make the association in the registry. At a fundamental level, you create a key in the right branch that associates the extension to your exe. 

I used to know it back in the day, HKEY_LOCAL_MACHINE/... (Win95) But Since then they've added protections such that if you are installing for the machine, you need admin privielges to edit that branch of the registry. Nowdays it's in HKEY_CURRENT_USER or something to that effect so that you can install the association on a per-user basis and not need admin. Most installers support adding a simple association. QSettings is capable, IIRC, if your installer doesn't have the capabilty.

Subject: [Interest] Launch Qt Desktop Application(Windows) by clicking custom file

Hello all,

 

I want to ask you that How can I launch my Qt desktop application(Windows) when double click to a custom file that is used by my application?

 

For example, when I double click myFile.x then my application will launch and open this file.

 

Thanks in advance.

 

Best Regards,

 

Berkay Elbir
