[Qt Installer Framework] Run a batch file during uninstallation

akhi95

Hi, is there a way to run a batch file during uninstallation of an app created using Qt Installer Framework?

Ok, I found the correct file.

seems like I abandoned the shell script on deinstall and went directly to this entry

Component.prototype.createOperations = function() {
...
component.addOperation("Execute","echo", "do nothing","UNDOEXECUTE","rm", "-rf", "@HomeDir@/Desktop/MyApp");
}

@akhi95 sure

listen to the uninstallationStarted signal, and connect a function to it. In that function call the script.

I use it to remove desktop (shortcut) icons on MacOS

function Component()
{
...
    installer.uninstallationStarted.connect(onUninstallationStarted);
}

onUninstallationStarted = function()
{
    var argList = ["@TargetDir@/myApp.app/Contents/MacOS/data/remove-alias.sh"];
    installer.execute("sh",argList);
}

@J-Hilk Thanks for the reply. Since an hour, I have been trying to make your code work for my batch script but I'm unable to do so. I'm doing something like this

function Component()
{
...
    installer.uninstallationStarted.connect(onUninstallationStarted);
}

onUninstallationStarted = function()
{
    var argList = ["@TargetDir@/test.bat"];
    installer.execute("bat",argList);
}

Sorry I'm not a "Qt Installer Framework" person, but what is your installer.execute("bat", ...;? bat is no kind of Windows command. If you need something there I would have thought it would likely be one of the following:

var argList = ["@TargetDir@/test.bat"];
installer.execute("cmd",argList);

var argList = ["/c", "@TargetDir@/test.bat"];
installer.execute("cmd", argList);

var argList = [];
installer.execute("@TargetDir@/test.bat", argList);

? There ought be Google examples somewhere?

@akhi95
@JonB is correct you will probably want to call the commandpropt for that batch file.

That said, I may have given you a faulty example. I copy pasted from one I have still on my PC and I struggle to get it to work.

But I have some google coordinates for you, that may also help:

I'll post again, if I manage my example to work as well, it's been over a year for me 🙈

This worked! Thanks a ton! Initially, I didn't notice the neat little trick you did by doing nothing in the Execute part.
