Duration of a ToolTip

It works

HOW?!

QToolTip * b;
a= QString("%1 , %2").arg(x).arg(y);
b->showText(g, a );

should mercilessly crash

@VRonin Yes it works, I can also write: QToolTip::showText(g, a ); it's the same thing..but it'isn't this the problem

I see, it's static.
try adding setToolTipDuration(30000); in CustomPlotZoom::CustomPlotZoom and change QToolTip::showText(g, a ); to QToolTip::showText(g, a, this);

@VRonin I wrote:

CustomPlotZoom::CustomPlotZoom(QWidget * parent)
: QCustomPlot(parent)
, mZoomMode(false)
, mRubberBand(new QRubberBand(QRubberBand::Rectangle, this))
{
setToolTipDuration(3000);
}

and:

QToolTip::showText(g, a ,this);
but it doesn't work

I'm retarded, sorry. http://doc.qt.io/qt-5/qtooltip.html#showText-2
QToolTip::showText(g, a, this, QRect(), 30000);

It doesn't work..maybe it's because it's connected to mouse event? I don't understand

Define "doesn't work".

• Crashes
• Doesn't show the popup at all
• Shows the popup but not for 30secs

@VRonin the third

Hi
Just as a note.
I tried the code
QToolTip::showText(g, a, this, QRect(), 30000);
from a button's clicked.
It will stay for 30 secs IF you do not move the mouse.
If you mouse the mouse - it vanish a few sec later.
So i think that is what you are seeing.
