Support for touch devices

Reported by: jri Owned by: jri
Priority: Major Milestone: Release 4.7
Component: DeepaMehta Standard Distribution Version: 4.6.1
Keywords: Cc: dgf, Malte, JuergeN
Complexity: 5 Area: GUI / Usability
Module: deepamehta-webclient


The Webclient should also work on touch devices like Android and iOS tablets and phones.

Currently only tapping and double-tapping works. That is topic/assoc selection and editing and menu selection work already. However what does NOT work is all the drag operations.

Optimize canvas resizing (#803).

The canvas element is not recreated several times while resizing.
The hope was better rendering performance on mobile Firefox. But no luck.
Mobile Firefox still crashes while resizing.
Mobile Chrome works much better.

See #803.

Mobile: improve page panel resize handling (#803).

The width of the resize-handle is increased from 7px to 16px to make it easier to grasp.

When tapped the resize-handle appears visually to provide a hint where to grasp it.

Still, resizing remains very frustrating. Most resize attempts fail.
The various mobile browsers seem to be governed by subtle and opaque rules.

See #803.
See #676.

The first round is regarded complete.

Please test with various touch devices.

Currently only tested with an Android 4.1 tablet and mobile Firefox and Chrome browsers.
Chrome works best.
