onmouseover and onmouseclick

ok, and what do i have to do?

I think nothing. It have to be work as is.
Just use internal parser in file layer type

Yes, I tried that, but none of the settings worked.
Which setting exactly do I have to make?

Hello,
there is no setting for this in the program.
I need the code for:
Tooltip content for Placemark.
But there is only
Popup content for placemark

I do not create tooltips for placemarks, created by KML/GPX files.

This property is Title. It set for placemarks and placemarks, created by internal parser for KML/GPX files.

Yes, for simple placemarks (created by placemark menu), you can assign hover content, which creates tooltip. But this feature is not implemented for placemarks from KML/GPX file

But what amazes me, why you can read it with Popup but not with Tooltip.
