General mechanics

Interaction#

These are interaction events widgets are likely to respond to:

Mouse Touch Description
Mousedown Tap Handled at pressing time, not releasing.
Click Click Handled at release time.
Double Click Double Tap Some widgets handle double click / double tap events. 
Drag Drag  The widgets respond to mouse and touch drag gestures with a 1:1 precision ratio.

Widgets sensibility can be tuned with the sensibility property. Single-touch widgets (i.e. all widgets except mutlixy and range) also accept an alternate interaction event for fine control.

Mouse Touch Description
Ctrl + Drag / Holding the Ctrl key while dragging with the mouse increases the gesture's precision by 10.
/ Two-fingers drag  Using two fingers on a single-touch target increases the gesture's precision by 10.

Sending messages#

When interacted with, widgets with at least one target (including the server's defaults) send osc messages of the following form:

/address ...preArgs ...value

If they have MIDI targets, the server will try to convert the osc messages into a MIDI messages (see MIDI messages).

Receiving messages#

When an osc message is received, it updates every widgets that meets the following conditions

  • same address
  • same preArgs (no distinction between integers and round floats )

The remaining arguments after preArgs are passed to the widget.

When a MIDI message is received, it's converted into an osc message (see MIDI messages) and follows the same rules, except that only the widgets that include the emitting MIDI device in their targets will be able to receive it.

Widget synchronization#

Within a single client's scope, there are multiple ways to synchronize widgets:

  • If they share the same id: in this case, the synchronized widget doesn't send any osc/midi message. This case is mostly used for widget cloning.
  • If they share a linkId: in this case, the synchronized widget sends its osc/midi message normally.
  • If their value properties depend on each other using the advanced syntaxes
  • Using scripting

Client synchronization#

From a client to another, widgets are automatically synchronized if they share the following properties:

  • address
  • preArgs
  • targets
