How to set the Exec and Icon in *.desktop file with help of installer?

Yash001

I am using Ubuntu 18.04 and Qt 5.13.1.

I created package of my application and *.desktop file.
*.desktop file I am setting Exec and Icon manually.

Is it any way to set the Exec and Icon value with help of installer? similar like Qt does in DigiaQt-qtcreator-Community.desktop?

Here my *.desktop file

[Desktop Entry]
Type=Application
Exec=***APP_PACKAGE_PATH***/SquidStat.sh
Name=Squidstat
GenericName=The IDE of choice for Squidstat handle.
Icon=***APP_PACKAGE_PATH***/Squidstat.png
StartupWMClass=qtcreator
Terminal=false
Categories=IDE;Qt;

In general, How can I set the APP_PACKAGE_PATH inside the installer?

It may save other time.

Call below function from installer.qs for creating *.desktop file

you can call prototype by this. desktopFileCreateOnLinux() from any function in side component script.

Below script will create the two place *.desktop file.

inside the @TargetDir@/
inside ~/.local/share/applications/ (it will help while searching from Show application).

prototype definition:

Component.prototype.desktopFileCreateOnLinux = function() 
{
    if ((systemInfo.kernelType === "linux") ||(systemInfo.kernelType === "Linux")) {
    var dir = installer.value("TargetDir");
    component.addOperation("CreateDesktopEntry", "Squidstat.desktop",
                           "Type=Application\nName=Squidstat\nExec=\'"+dir+"/SquidStat.sh\'\nGenericName=The IDE of choice for Squidstat handle.\nIcon="+dir+"/Squidstat.png\nTerminal=false\nCategories=IDE;Qt;");
    component.addOperation("CreateDesktopEntry", "@TargetDir@/Squidstat.desktop",
                           "Type=Application\nName=Squidstat\nExec=\'"+dir+"/SquidStat.sh\'\nGenericName=The IDE of choice for Squidstat handle.\nIcon="+dir+"/Squidstat.png\nTerminal=false\nCategories=IDE;Qt;");
    }
}
