Touchscreen adaptation #401

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
On the Caanoo, the main input device is touchscreen with stylus. A big 
difference with a tablet is that it's impossible to get feedback of mouse 
position before click. The "workflow" of some of Grafx2 tools is not ideal with 
this.

Htdreams reported this with 3-point curve: After clicking and dragging to set 
start and end points, you move somewhere and click. With a mouse or PC Tablet, 
you'd get real-time preview of the curve. On the Caanoo or using a physical 
touchscreen anywhere, you can only see the preview when you click, but then 
it's too late to change.

In this case, the click should start preview - but then you should be allowed 
to drag the cursor to new position, and only when you release the pressure it 
should set the figure.
I don't think we should make this the default behaviour on all platforms, 
because the tool would become prone to moving slightlty after click.

An option (possibly at compile-time, if it's simpler) should alter the way this 
tool works. If we find other tools that require similar change, the same option 
should control them all.
