Mouse events.
|
|
|
|
|
|
How it works
|
|
------------
|
|
|
|
The renderer has a 2 dimensional grid of mouse event handlers.
|
|
(`prompt_toolkit.layout.MouseHandlers`.) When the layout is rendered, the
|
|
`Window` class will make sure that this grid will also be filled with
|
|
callbacks. For vt100 terminals, mouse events are received through stdin, just
|
|
like any other key press. There is a handler among the key bindings that
|
|
catches these events and forwards them to such a mouse event handler. It passes
|
|
through the `Window` class where the coordinates are translated from absolute
|
|
coordinates to coordinates relative to the user control, and there
|
|
`UIControl.mouse_handler` is called.
