How to assign an icon to a file type of a Qt program using the installscript file

[JonB]

I am assuming your statement "But when I make the installer this way, no icon will be set on the file type of the program." you mean that you are not seeing the right icon on a .sp file, not the icons on the 3 shortcuts to your .exe ... right?

If I were trying to solve this, I would go:

• Google for "windows set file types icon". You'll have to read something like https://superuser.com/questions/301226/manually-change-filetype-icons-in-windows-7 or https://www.howtogeek.com/howto/12383/change-a-file-types-icon-in-windows-7/ or there's even a video at https://www.youtube.com/watch?v=tEer0_LjRQY. Looks like you'll either need to download a bit of freeware to do it nicely, or read up on how to do it directly in the Registry.
• Get your .sp associated with your .exe and get its icon assigned to whatever you want.
• Search registry for mentions of your .ico file and see what it put where.

For all I know, it might not be possible to associate a .ico file with a file type. Usually the way this is done is to embed the icon inside your .exe and set the icon by pointing into the .exe correctly. (That is what the example http://doc.qt.io/qtinstallerframework/qt-installer-framework-registerfileextension-example.html I mentioned does; I don't actually see other examples where an external .ico file is used. Actually see https://msdn.microsoft.com/en-us/library/windows/desktop/hh127427(v=vs.85).aspx too, which implies it should work for a .ico.) Like I said, I have never actually done this, I'm just pointing the way for you....

Yes. All three shortcuts have the icon set on themselves. By running them the program shows up.
But on the files having the extension .sp, no icon is set.

Please note that I thinking about the users for whom I will send the file to install it on their Windows machine. Setting the icon should be done in the process of installation.

For all I know, it might not be possible to associate a .ico file with a file type.

Please look at this:

Those two .docx and .xlsx have icons on themselves but the .sp file has no one it itself.

I am not suggesting that your end users will have to Google for or do the file type icon association themselves! I'm suggesting you need to do so, as a "test run", in order to know what you need/does/does not work from the Qt Installer!

I do understand the screenshot you are showing. You could either search the Registry to see how that is done for .xslx file types (btw, I think you'll find the icons are embedded in the WORD.EXE application not an external .ico file, though that may not be relevant), or you could follow the steps I have suggested.

At the end of the day, I suspect your problem is how to do it right under Windows, rather than anything specific to do with Qt Installer. (Though I did suggest you just try using \ instead of / in your CreateShortcut's iconPath specification, that a very quick that's might be worth a try.)

@JNBarchan

is that a typo?
with forward-slash

I read Docs and a thread and modified the script file and tried to install the app many times but no success. This is the last modification:

component.addElevatedOperation("RegisterFileType", "sp",
        "@TargetDir@/Spreadsheet.exe/" %1/"", "Abbasi Files", "application/Abbasi",
        "@DesktopDir@/Spreadsheet.ico", "ProgId=Spreadsheet.sp")

Play with that till it works, bring back any alterations to your Qt Installer Script?

What do you mean?

get it working manually from Windows and see how that compares to what the Installer produces.

I couldn't find a clear and not-difficult way to register a file type on registery to compare it with the path and values the installer makes.
The installer creates a value in the path below:

RegisterFileTypeOperation::performOperation()
Get your .sp associated with your .exe and get its icon assigned to whatever you want.

I couldn't understand these well.

You could either search the Registry to see how that is done for .xslx file types

Here is that which is much more complicated than the one for .sp:

(Though I did suggest you just try using \ instead of / in your CreateShortcut's iconPath specification, that a very quick that's might be worth a try.)

I did it, and test it many times. No success until now.

Did you test it on your system?

Something new happened!
I searched for .sp in the registery and deleted all of them there.
Then installed the program and restarted the Windows. This is the result:

The icon is set on both files 1 & 2.

I ran the app using that shortcut and opened the files using the Open button. They opened. => No changes on files. Good.

Then opened the files (1 & 2) using double clicking and chosing the application to run and "unchecked" the button:
Always use the selected program to open this kind of file.
Again they were opened and no changes on icons. Good.

This time I checked that button and ran the files again. And it's the outcome: :( :(

@tomy You associated now this file type with your app. Does your app have an registered icon?

I'm not sure what you mean by registered icon, but, the shortcut above the files 1 and 2 at the screenshot above has an icon on itself and when double clicked, it runs the application. I put the icon in the folder data of the package directory folder and using it the installer registered that icon for the program I think.

@tomy Is your app shown with an icon in Windows (start menu for example)?
