Tool Plugins¶
Tool Plugins allow the creation of new editor tools, which give the user new ways to interact with the world by clicking and dragging in the world viewport. Each tool plugin may provide an “options widget” which is shown in the tool options panel while the tool is selected. A tool plugin may implement mouse event handlers, which will recieve 3D coordinates in world space cooresponding to the mouse position.
A tool plugin may also provide a 3D mouse cursor in the form of a SceneNode. Alternately,
a 2D mouse cursor may be implemented by calling QCursor functions in your implementations
of toolActive and toolInactive
Mouse Handlers¶
These mouse handlers are called in response to user actions. A simple tool may only
implement mousePress or mouseRelease, while a tool that also allows dragging or
changes its cursor according to world position may also implement mouseDrag or
mouseMove.
