[SOLVED] Calling menu function in another form

sharon_obl82

Hi, I need advice on this issue. Basically I'd like to call Report function in mainwindow.cpp from another form called radiowindow.cpp to display out Report window.

radiowindow.cpp:
@

QString value;

void RadioWindow::on_actionReport_triggered()
{
value = "Radio";
MainWindow report;
report.getvalue(value);
report.on_actionReport_triggered();

}
@

I have a get value from radiowindow.cpp in mainwindow.cpp

mainwindow.cpp:
@

QString gvalue;

void MainWindow::getvalue(QString valuereceived)
{
gvalue =valuereceived;
}

void MainWindow::on_actionReport_triggered()
{

tablevalue = gvalue;
qDebug() << "tablevalue in report is" << tablevalue;

if (tablevalue == "Radio")
    {

        report =new Reportwindow(this);
        report->setWindowIcon(QIcon(":/icons/qt-icon80.ico"));
        report->setWindowTitle("Radio - User Configuration Manager");
         qDebug() << "enter if" << tablevalue;
        report->show();

    }
    else if (tablevalue == "Radio User")
    {
        ruser_report =new radiouser_report(this);
        ruser_report->setWindowIcon(QIcon(":/icons/qt-icon80.ico"));
        ruser_report->setWindowTitle("Radio User - User Configuration Manager");
        ruser_report->show();

    }

}

bq. I can’t seem to be able to display the report form :( what am i missing here?

That is because the MainWindow object gets destroyed as soon as the function exits.
@
void RadioWindow::on_actionReport_triggered()
{
value = "Radio";
MainWindow report;
report.getvalue(value);
report.on_actionReport_triggered();

}

Create the MainWindow object on heap using the new keyword.

Hi,

There's also a flow in your program logic: MainWindow creates a new RadioWindow which creates a MainWindow. These two MainWindow are not the same.

I would recommend first taking a look at the signal and slot chapters and examples
