Package gaphas :: Module tool

Module tool

Tools are used to add interactive behavior to a View.

Tools can either not act on an event (None), just handle the event or grab the event and all successive events until the tool is done (e.g. on a button press/release).

The tools in this module are made to work properly in a ToolChain.

Current tools:

ToolChain - for chaining individual tools together. HoverTool - make the item under the mouse cursor the "hovered item" ItemTool - handle selection and movement of items HandleTool - handle selection and movement of handles RubberbandTool - for Rubber band selection PlacementTool - for placing items on the canvas

Maybe even:

TextEditTool - for editing text on canvas items (that support it)

(context.view = view; context.grab() to grab, context.ungrab() to ungrab)
