HGDial Open Source

This new control will revolutionize UX forever!

HGDIAL is more than just a simple dial control. It is rich in features and designed to achieve maximum usage scenarios.

This Dial Features:

1 The ability to record the direction of rotation.

2 Allows precision rotation settings causing the dial to rotate at a different rate than the gesture (including the ability to rotate in the opposite direction of the gesture).

3 It records the number of gesture rotations.

4 It records the number of image rotations.

5 It has a cumulative dial setting. When enabled the rotation will occur relative to the touch; and disabled the rotation will start from the point where the gesture starts.

6 It has an advanced angle snap feature with an angle snap tolerance setting. The tolerance causes the dial to rotate freely until the snap tolerance is met.

7 The dial can operate in single or dual finger mode.

8 With this dial it is possible to set a minimum/maximum rotation constraint.

9 It has a variable dial behaviour causing the rotation rate to change depending on how close the gesture is the centre of the dial.

10 This library comes with a 'fling-to-spin' behaviour; having configurable fling tolerance, spin start/end speed and spin animation duration.

11 A key feature is that the dial controls are designed to interact with each other and any other widgets/layouts that implement touch listeners.

12 All of the above features play together in perfect harmony.

13 It has an array of convenience methods that greatly enhances usage scenarios.

This library supports API 9+ and uses Canvas/Extended Views. There is a OpenGLES 2.0 version of this library which has a distorted dial feature and handles dials acting upon other dials better than this library.
