How to launch my software when the installation is finished? (Qt Installer Framework)

[julia_f]

Hi All,

I would like to execute my application after the installation for Windows throught Qt Framework Installer. My goal is to update my software when an update is available like that https://stackoverflow.com/questions/34318934/qt-installer-framework-auto-update .

There are the steps :

• Click on the shortcut and launch my software
• Check if an update is available
• If no update available, continue
• If an update is available, call "maintenancetool --updater"
• Quit my software
• Install my update (Qt Installer Framework based)
• At the end of my installation and the installation window is closed, I would like to launch my software???

My question is : how to launch my software when the installation is finished??

Apparently, you are using already QProcess for the installer update check.

You can simply use also QProcess and start your application again after update.

I would like that my software does a software update itself. I need to stop my software before to do a software update (with my installer) cuz in Windows, you cannot delete an executed program. And at this point, you must to launch the software in the installer script.

I would like to know how to do that in the installer script (not in my software/c++)

@julia_f Did you solve the problem? Because I have the same problem.

@CKurdu , @julia_f

The answer (I think) is see RunItCheckBox in topic Finished Page on page http://doc.qt.io/qtinstallerframework/noninteractive.html

The source code at https://github.com/qtproject/installer-framework/blob/master/src/libs/installer/packagemanagergui.cpp shows that if it's checked it does:

3202     qDebug() << "starting" << program << args; 
3203     QProcess::startDetached(program, args);

I made it by controller script

function Controller()
{
	 installer.installationFinished.connect(function() {

			 var isUpdate = installer.isUpdater();
			
			 if(isUpdate)
			 {
				 var targetDir = installer.value("TargetDir");
				 console.log("targetDir: " + targetDir);
				 installer.executeDetached(targetDir+"/WebSourceManager.exe");			 
				 
			 }else{
				 		 	 var result = QMessageBox.question("quit.question", "Start Program", "Do you want to start the installed application?",QMessageBox.Yes | QMessageBox.No);
						 if( result == QMessageBox.Yes)
					 {
						 var targetDir = installer.value("TargetDir");
						  console.log("targetDir: " + targetDir);
						  console.log("Is Updater: " + installer.isUpdater());
						  console.log("Is Uninstaller: " + installer.isUninstaller());
						  console.log("Is Package Manager: " + installer.isPackageManager());
						  installer.executeDetached(targetDir+"/WebSourceManager.exe");			 
					 }
				 
			 }
			 
		
    });
	installer.updateFinished.connect(function(){
		var targetDir = installer.value("TargetDir");
		console.log("targetDir: " + targetDir);
		installer.executeDetached(targetDir+"/WebSourceManager.exe");	
	});

}
