Mouse provider implementation¶
On linux systems, the mouse provider can be annoying when used with another multitouch provider (hidinput or mtdev). The Mouse can conflict with them: a single touch can generate one event from the mouse provider and another from the multitouch provider.
To avoid this behavior, you can activate the “disable_on_activity” token in the mouse configuration. Then, if any touches are created by another provider, the mouse event will be discarded. Add this to your configuration:
[input]
mouse = mouse,disable_on_activity
Using multitouch interaction with the mouse¶
バージョン 1.3.0 で追加.
By default, the middle and right mouse buttons, as well as a combination of ctrl + left mouse button are used for multitouch emulation. If you want to use them for other purposes, you can disable this behavior by activating the “disable_multitouch” token:
[input]
mouse = mouse,disable_multitouch
バージョン 1.9.0 で変更.
You can now selectively control whether a click initiated as described above will emulate multi-touch. If the touch has been initiated in the above manner (e.g. right mouse button), a multitouch_sim value will be added to the touch’s profile, and a multitouch_sim property will be added to the touch. By default, multitouch_sim is True and multitouch will be emulated for that touch. If, however, multitouch_on_demand is added to the config:
[input]
mouse = mouse,multitouch_on_demand
then multitouch_sim defaults to False. In that case, if multitouch_sim is set to True before the mouse is released (e.g. in on_touch_down/move), the touch will simulate a multi-touch event. For example:
if 'multitouch_sim' in touch.profile:
touch.multitouch_sim = True
Following is a list of the supported values for the
profile property list.
| Profile value | Description |
| button | Mouse button (one of left, right, middle, scrollup or scrolldown). Accessed via the ‘button’ property. |
| pos | 2D position. Also reflected in the
x,
y
and pos
properties. |
| multitouch_sim | Specifies whether multitouch is simulated or not. Accessed via the ‘multitouch_sim’ property. |
