This introduces a much more consistent set of events within the editor for whenever a element is added, removed or modified. The events emited on the `RED.events` event system. The event names take the form: `"<thing>:<action>"`. `<thing>` can be one of: - nodes - flows - subflows - groups - links `<action>` can be one of: - add - remove - change The payload of the events is the object in question. There is also: - flows:reorder - when tabs are reordered. Payload is array of flow ids. - workspace:clear - when the workspace is emptied - part of switching projects The `nodes:change` event was already used by RED.nodes.dirty() to cause the Deploy button to become active. This renames that event to: - workspace:dirty - Payload is boolean flag for the dirty state This commit also updates the Palette to use the subflows:change event to only redraw subflows that have actually changed rather than refresh them all whenever one of them *might* have changed. This removes a noticable flicker of the icon which was needlessly being redrawn. |
