Hover Event - 2 windows

[SGaist]

Which hoverLeave method ?

What about QWidget::leaveEvent ?

[TomNow99]

@SGaist hoverLeave method is my method which is execute when there is QHoverEvent. I think in this example QWidget::leaveEvent and QHoverEvent are very simillar.

[SGaist]

Then please show your code.

@SGaist I don't have it on thic pc, so I can only give you some pseudoCode:

bool MainWindow::event(QEvent * e)
{
    switch(e->type())
    {
    case QEvent::HoverEnter:
        hoverEnter(static_cast<QHoverEvent*>(e));
        return true;
        break;
    case QEvent::HoverLeave:
        hoverLeave(static_cast<QHoverEvent*>(e));
        return true;
        break;
    default:
        break;
    }
    return QWidget::event(e);
}

void MainWindow::hoverEnter(QHoverEvent * event) 
{
     if( !label -> isVisible() )
     {
          label->show();
     }
}
void MainWindow::hoverLeave(QHoverEvent * event) 
{
     if( label -> isVisible )
     {
          label->hide();
     }
}

EDIT:
I have while(true) here :) When I have cursor in label I have loop:
hide->show->hide->show->hide->...

[SGaist]

Why a while ? You will only manage to block the event loop.

[TomNow99]

@SGaist Could you give me some snippet - I don't do this before

[SGaist]

A snippet of what ?

[TomNow99]

@SGaist Blocking event loop

[SGaist]

You do not want to block the event loop. That will freeze your GUI.

@SGaist Now in functions hoverEnter and hoverLeave I do:

qInfo()<<"enter"; 
or
qInfo()<<"leave"; 

When my mouse cursor is in place, where label is I see in QT words:
enter, leave, enter, leave, enter, leave, enter, leave, enter, leave, enter, leave, enter, leave, enter, leave, ...

And I see that my label is hidden -> shown ->hidden -> shown ->hidden -> shown ->hidden -> shown ->hidden -> shown ->hidden -> shown ->...

How can I do what I want ( picture ) ?
