seesaw.cursor — seesaw 1.5.0

Functions for creating Swing cursors.

cursor clj

(cursor type & args)

Create a built-in or custom cursor. Take one of two forms:

(cursor :name-of-built-in-cursor)

Creates a built-in cursor of the given type. Valid types are:

:crosshair :custom :default :hand :move :text :wait :e-resize :n-resize :ne-resize :nw-resize :s-resize :se-resize :sw-resize :w-resize

To create custom cursor:

(cursor image-or-icon optional-hotspot)

where image-or-icon is a java.awt.Image (see seesaw.graphics/buffered-image) or javax.swing.ImageIcon (see seesaw.icon/icon). The hotspot is an optional [x y] point indicating the click point for the cursor. Defaults to [0 0].

Examples:

; The hand cursor (cursor :hand)

; Create a custom cursor from a URL: (cursor (icon "http://path/to/my/cursor.png") [5 5])

Notes: This function is used implicitly by the :cursor option on most widget constructor functions. So

  (label :cursor (cursor :hand))

is equivalent to:

  (label :cursor :hand)

Same for setting the cursor with (seesaw.core/config!).

Also, the size of a cursor is platform dependent, so some experimentation will be required with creating custom cursors from images.
