slot close widget shows an other empty dialog

mourad_bilog

Porting my Qt 4 application to Qt 5 on Mac OS 10.10, I'm encoutring a strange function. I'm creating a Widget from a mainWindow :

if(workspace->subWindowList().contains((QMdiSubWindow *)frmHisto))
    {
        workspace->setActiveSubWindow(qobject_cast<QMdiSubWindow *>(frmHisto));
        return;
    }

    frmHisto = new frmListeOrdo(this);
    workspace->addSubWindow(frmHisto);/

    connect(frmHisto, SIGNAL(prescrire(int,int,Patient*,Abonne *)), this, SLOT(showPrescription(int,int,Patient*,Abonne *)));
    connect(frmHisto, SIGNAL(showMe()), this, SLOT(showHisto()));

    if(workspace->subWindowList().contains(qobject_cast<QMdiSubWindow *>(frOrdo)))
        connect(frOrdo, SIGNAL(changeOrdo()), frmHisto, SLOT(refreshOrdo()));

    frmHisto->show();
    frmHisto->setWindowState(Qt::WindowMaximized);
    
    workspace->setActiveSubWindow(qobject_cast<QMdiSubWindow *>(frmHisto));
    frmHisto->setFocus();

In the frmHisto, I've a pushButton to close the Widget and I've added the closeEvent method

connect(pbFermer, SIGNAL(clicked()), this, SLOT(fermer()));

void frmListeOrdo::fermer()
{
    close();
}

void frmListeOrdo::closeEvent(QCloseEvent *event)
{
   event->accept();
}

but When I click the pushButton to close the Widget, I've an empty frmHisto Widget !

This problem is not reproduced when I click the "X" close button of the Widget.

Can tell me what's wrong and how to resolve this

does static_assert(std::is_base_of<QMdiSubWindow,frmListeOrdo>::value); complain?

Thanks for replying

I'm encoutring to use static_assert(std::is_base_of<QMdiSubWindow,frmListeOrdo>::value); because of compilation errors

I'll try again and return to you

@mourad_bilog said in slot close widget shows an other empty dialog:

because of compilation errors

Yes, compilation errors is what I'm looking for. If your compiler says that a static assertion failed it's what I wanted to know

And what I must to do to resolve the problem of closing ?

Note that with the dialog button close ("X"), it works fine and it call the closeEvent method and emits event->accept.

Hi,

Out of curiosity, why are you re-implementing closeEvent just to accept the event ? There's no need for that if it's the only thing you do.

Thanks for reply.

Well I'm testing solution I found after searching. You are wright, reimplenting closeEvent don't resolve the problem witch persists.

What I've to modify to close the Widget when I click on the close button et not the Widget close ("X").

close button calls the close() method.

Thanks for your help
