get undoZoom-event

[Juergen]

Hi,
is it possible to cath an undoZoom-event, maybe as adding a listener? Or must i switch off TChart-zoom and create my own zomm by Mouseevents of the Window?
Baground of my Question is if user use undoZoom via mouse the view shoud show 110% instead of 100%.

Hi juergen,

Yes, the following code seems to work fine for me here:

Code: Select all

        tChart1.addChartMotionListener(new ChartMotionListener() {
            
            @Override
            public void scrolled(ChartEvent e) {
                tChart1.getHeader().setText("Scrooled");
            }

            @Override
            public void zoomed(ChartEvent e) {
                tChart1.getHeader().setText("Zoomed");
            }

            @Override
            public void unzoomed(ChartEvent e) {
                tChart1.getHeader().setText("UnZoomed");
            }
        });

That's it.

Hello Yeray,

We are trying to get unzoom event as your example by adding a ChartMotionListener.
But the listener was never triggered.

Do you have an any idea?

We are using TeeChart SWT version 0722fg.

Thanks!
Ishan.

Hi,

You are right. It was broken. I've just corrected for the next maintenance release.
