5.14 Window

Emacsy aims to offer the minimal amount of intrusion to acquire big gains in program functionality. Windows is an optional module for Emacsy. If you want to offer windows that behave like Emacs windows, you can, but you aren’t required to.

Class: <window>

The window class contains a renderable window that is associated with a buffer.

Class: <internal-window>

The internal window class contains other windows.

Variable: root-window

Variable: window-configuration-change-hook

Variable: current-window

Scheme Procedure: initialize (obj <internal-window>) initargs

Scheme Procedure: window? o

Scheme Procedure: window-live? o

Scheme Procedure: frame-root-window

Scheme Procedure: edges->bcoords edges

Emacs uses the edges of windows (left top right bottom), but I’m more comfortable using bounded coordinate systems (left bottom width height). So let’s write some converters.

Scheme Procedure: bcoords->edges coords

Scheme Procedure: window-clone (window <window>)

Scheme Procedure: selected-window

Scheme Procedure: update-window (window <internal-window>)

Scheme Procedure: window-tree (w <internal-window>)

Scheme Procedure: window-tree (w <window>)

Scheme Procedure: window-list #:optional (w root-window)

Interactive Procedure: split-window #:optional (window (selected-window)) (size 0.5) (side (quote below))

Be careful with deep-clone. If you deep clone one window that has references to other windows, you will clone entire object graph.

Interactive Procedure: split-window-below #:optional (size 0.5)

Interactive Procedure: split-window-right #:optional (size 0.5)

Interactive Procedure: delete-window #:optional (window (selected-window))

Interactive Procedure: other-window #:optional (count 1)
