remove of all QwtPlotCurves

[gyre]

Hi I was trying to remove all curves from QwtPLot...I did not succed (otherwise I wouldnt write here )
I thought this would do that for me:

trendPlot->detachItems(QwtPlotItem::Rtti_PlotCurve, true);

trendPlot->detachItems(QwtPlotItem::Rtti_PlotCurve, true);

To copy to clipboard, switch view to plain text mode 

I was wrong...so I tried to reimplement detachItems method...but did not succed ...
Anyone help pls ?
Thanks

Guess you simply forgot to call replot() to make your changes happen. You can also enable the autoReplot flag, but this might lead to too many updates.

Thanks a lot man...that replot() thing helped...
Can I ask you another question about that QwtPlotZoomer ?
I have reimplemented it as you advised me to:

connect(zoomToolButton, SIGNAL(toggled(bool)), SLOT(enableZoomMode(bool)));
 
void MainWindow::enableZoomMode(bool on)
{
	dataPanner->setEnabled(on);
 
	dataZoomer[0]->setEnabled(on);
	dataZoomer[0]->setZoomBase();
 
	dataZoomer[1]->setEnabled(on);
	dataZoomer[1]->setZoomBase();
 
	dataPicker->setEnabled(!on);
}

connect(zoomToolButton, SIGNAL(toggled(bool)), SLOT(enableZoomMode(bool)));

void MainWindow::enableZoomMode(bool on)
{
	dataPanner->setEnabled(on);

	dataZoomer[0]->setEnabled(on);
	dataZoomer[0]->setZoomBase();

	dataZoomer[1]->setEnabled(on);
	dataZoomer[1]->setZoomBase();

	dataPicker->setEnabled(!on);
}

To copy to clipboard, switch view to plain text mode 

It works just fine...the only SIMPLE problem I suppose is that now when I do some zooming...and then when I toggle the button to "get out/cancel" the zooming the plot does not return to the original state as it was displayed before zooming...
Have any ideas ?
Thanks

void MainWindow::enableZoomMode(bool on)
{
        ...
        if ( on ) {
             dataZoomer[0]->setEnabled(on)
             dataZoomer[0]->setZoomBase();
        }
        else {
            dataZoomer[0]->zoom(0); // zoom out
            dataZoomer[0]->setEnabled(on);
        }
        ...
}

void MainWindow::enableZoomMode(bool on)
{
        ...
        if ( on ) {
             dataZoomer[0]->setEnabled(on)
             dataZoomer[0]->setZoomBase();
        }
        else {
            dataZoomer[0]->zoom(0); // zoom out
            dataZoomer[0]->setEnabled(on);
        }
        ...
}
