Execute qml->build execute file from Another qml gui

Joshika_Namani

Hi everyone,
I'm trying to figure out, how to qml build run file from another qml gui button, when onclicked event happened, it should execute another qml build exe file, I have tried with QProcess, but I'm unable to figure out QProcessEnvironment for qml build.

QString filepath="/QML TYPES/build-Task-Desktop_Qt_5_15_0_GCC_64bit-Debug/Task";
QProcess process;
QProcessEnvironment env = QProcessEnvironment::systemEnvironment();
env.insert("TMPDIR", "/home/ubuntu/Qt/5.15.0/gcc_64/bin/qml"); // Add an environment variable
env.insert("COMPILER", env.value("Compiler") + "/usr/lib/ccache/x86_64-linux-gnu-g++");
process.setProcessEnvironment(env);
process.start(filepath);

But, Unfortunately above code is not working, so, please help to get out of this issue.
Thanks in advance.

@Joshika_Namani hi
can you see any messages or errors in your 'application output' tab in QtCreator ?
also you can connect a slot to void QProcess::errorOccurred signal

No, After adding below line.
process.waitForFinished(-1).
but nothing happening. no error , no output.
And, my doubt is that process environment is correct or not.
