Interface DrawingControllerOptions

Where copy and paste move text. Defaults to navigator.clipboard; pass a port to route through a host's own transfer, or null to stay in the process-local clipboard entirely.

Whether a refused or failing clipboard write still lands in the in-process clipboard. Defaults to true, which is what makes copy and paste work between two charts on a page where the browser has denied clipboard permission.

Pass false for a host that would rather a failed copy be a failed copy: with it off, cut leaves the drawing alone when the write does not land, so a shape is never destroyed for a transfer that did not happen.

Style merged under every tool's own defaults.

The pointer gestures a held modifier key starts, each on unless set to false here, for a host whose own chart gestures already use that key. setOptions merges it flag by flag.

Undo depth. Default 50.

Draw the anchor of every study input that declares one (a price input with a timeKey and anchor: true): a handle at the point the pair names that drags both as one settings change and one step of this undo history. Default true; false draws none, and the inputs are still edited in settings and picked with Chart.beginPick('point'). Read when the controller is built: setOptions does not change it.

Snap new anchors to the O/H/L/C of the bar under the cursor. 'strong' always takes the nearest of the four; 'weak' only when one sits within a few pixels of the pointer, so a click on open space stays where it was made. true means 'strong' and false means 'off', which is what the boolean meant before the modes existed. Default 'off'. While a tool is armed the layer paints a ring where the next click will land.

How far a pasted or duplicated copy lands from its original, in bars along time and in screen pixels down the price axis. A copy that lands exactly on top of the original reads as nothing having happened. Defaults: 2 bars, 16 px.

Stay in the active tool after finishing a drawing. Default false.
