PinchArea handles pinch. MouseArea can handle drags, but only with a single finger. qtdeclarative/examples/quick/demos/photosurface demonstrates those interactions together; in order for it to work you must put the MouseArea inside the PinchArea. Well, I used PinchArea to zoom each item, but if you want to zoom the whole screen I guess you only need one. Likewise if you want to pan an area with multiple items you can use Flickable, which is also for single-finger flicking. Arbitrary multi-finger interactions are possible with MultiPointTouchArea but it's a little more complex to use. > taps, tap-and-holds, MouseArea is fine. About the old gesture framework, there are some bugs reported, but I don't have as much experience with it so can't say for sure which problems you will currently have. > and maybe some > custom thing to recognize a path when this is drawn inside a > particular widget.

It should be doable, but as you say drawing and recognizing a path will have to be some custom work I think. IMO path drawing is basic enough that we ought to have it in QtQuick some day - no promises of course. ;-) _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
