Program does not appear in TaskBar

[Arsenic]

I have a program that seems to (both in XP and Vista) not show on the taskbar when it is launched.

I launch the program but it never shows up on my task bar.

Here's how I initiate my program:


int main(int argc, char *argv[]){
QApplication app(argc, argv);
QString stylesheet("");
app.setStyleSheet(stylesheet);
PMain pm(0);
return app.exec();
}

PMain::PMain(QWidget *parent) : QWidget(parent) {
qmw = new QMainWindow(this);
Log("P system started.");
pui.setupUi(qmw);
rows = 10;
qmw->show();
connect(pui.actionSave, SIGNAL(triggered()), this, SLOT(s_Save()));
connect(pui.actionSave_As, SIGNAL(triggered()), this, SLOT(s_SaveAs()));
connect(pui.actionOpen, SIGNAL(triggered()), this, SLOT(s_Open()));
}


I used Designer to make my GUI which is what pui is.
I compile using qmake, make...

I don't know if it is related but there is also an error where when I click on the "X" of the program, it closes but the process doesn't disappear from task manager.

I'm using Qt 4.4 with mingw.

Presumably you wanted something like this:


int main(int argc, char *argv[]){
QApplication app(argc, argv);
QString stylesheet("");
app.setStyleSheet(stylesheet);
PMain pm(0);
pm.show(); // <--
return app.exec();
}

class PMain : public QMainWindow // <--
{
...
};

PMain::PMain(QWidget *parent) : QMainWindow(parent) {
Log("P system started.");
pui.setupUi(this); // <--
rows = 10;
connect(pui.actionSave, SIGNAL(triggered()), this, SLOT(s_Save()));
connect(pui.actionSave_As, SIGNAL(triggered()), this, SLOT(s_SaveAs()));
connect(pui.actionOpen, SIGNAL(triggered()), this, SLOT(s_Open()));
}

Thanks a lot Honorable Sir.
