Module: Vedeu::EscapeSequences::Mouse

Extended by:
Mouse
Included in:
Esc, Mouse
Defined in:
lib/vedeu/esc/mouse.rb

Overview

Provides mouse related escape sequences.

The X10 compatibility mode sends an escape sequence on button press encoding the location and the mouse button pressed. It is enabled by sending ‘e[?9h` and disabled with `e[?9l`.

On button press, xterm(1) sends ‘e[Mbxy` (6 characters). Here b is button-1, and x and y are the x and y coordinates of the mouse when the button was pressed. This is the same code the kernel also produces.

Normal tracking mode (not implemented in Linux 2.0.24) sends an escape sequence on both button press and release. Modifier information is also sent. It is enabled by sending ‘e[?1000h` and disabled with `e[?1000l`. On button press or release, xterm(1) sends `e[Mbxy`. The low two bits of b encode button information: 0=MB1 pressed, 1=MB2 pressed, 2=MB3 pressed, 3=release. The upper bits encode what modifiers were down when the button was pressed and are added together: 4=Shift, 8=Meta, 16=Control. Again x and y are the x and y coordinates of the mouse event. The upper left corner is (1,1).
