Gesture navigation style updates (may 2019)

This looks better:

Code: Select all

0(40,605)
0(40,605)
0(40,605)
0(40,605)
0(40,605)
0(40,605)
0(40,605)
Gesture start SoGesturePinchEvent(-338,707)
 -> GestureState
Gesture start SoGesturePinchEvent(-338,707)
Gesture end SoGesturePinchEvent(-338,707)
 -> IdleState

During the 0(40,605) outputs it zooms correctly (or vice versa). If I end zooming The camera position jumps and I get the three "Gesture" outputs.

0(blah,blah) looks like mouse wheel events are coming. It looks like gesture events are not properly generated, so it's probably best to make FreeCAD ignore them altogether on MacOS.

For zooming I use two fingers on the touchpad. Move them up is zooming out, moving down is zooming in. All this happens on the 0(blah,blah) events. Please don't disable them too , the rest can well be ignored, as far as I am concerned.

Does anything happen if you pinch instead, as if the touchpad is a touchscreen?

Yes, the zoomed object moves immediately at the lower right corner out of sight, in the same way as it did before after finishing zooming.

Output:

Code: Select all

Gesture start SoGesturePinchEvent(186,524)
 -> GestureState
Gesture start SoGesturePinchEvent(186,524)
Gesture data SoGesturePinchEvent(186,524)
Gesture data SoGesturePinchEvent(186,524)
Gesture end SoGesturePinchEvent(186,524)
 -> IdleState
Gesture start SoGesturePinchEvent(-378,838)
 -> GestureState
Gesture end SoGesturePinchEvent(-378,838)
 -> IdleState

So I looked at the code, and it's probably the double start event that is causing a problem. I have for some reason commented out the ignoring of extra start events (don't remember why I did, possibly as an attempt to fix some early bug), now I wonder if I can uncomment it and it fixes the problem... I'll experiment later, i'm overloaded right now.

quick question: should we open a ticket to track this ?

Why not?

@chrisb are these 2 separate issues? or all one?

[chrisb]

It's all in one.
