Constructors

cursorNew

Arguments

:: CursorType

cursorType cursor to create

-> IO Cursor

return a new Cursor

Creates a new cursor from the set of builtin cursors for the default display. See cursorNewForDisplay. To make the cursor invisible, use BlankCursor.

Methods

cursorNewFromPixmap

Arguments

:: Pixmap

source - the pixmap specifying the cursor.

-> Pixmap

mask - the pixmap specifying the mask, which must be the same size as source.

-> Color

fg - the foreground color, used for the bits in the source which are 1. The color does not have to be allocated first.

-> Color

bg - the background color, used for the bits in the source which are 0. The color does not have to be allocated first.

-> Int

x - the horizontal offset of the 'hotspot' of the cursor.

-> Int

y - the vertical offset of the 'hotspot' of the cursor.

-> IO Cursor

Creates a new cursor from a given pixmap and mask. Both the pixmap and mask must have a depth of 1 (i.e. each pixel has only 2 values - on or off). The standard cursor size is 16 by 16 pixels.

Removed in Gtk3.

cursorNewFromPixbuf

Arguments

:: Display

display the Display for which the cursor will be created

-> Pixbuf

pixbuf the Pixbuf containing the cursor image

-> Int

x the horizontal offset of the hotspot of the cursor.

-> Int

y the vertical offset of the hotspot of the cursor.

-> IO Cursor

return a new Cursor.

Creates a new cursor from a pixbuf. Not all GDK backends support RGBA cursors. If they are not supported, a monochrome approximation will be displayed. The functions displaySupportsCursorAlpha and displaySupportsCursorColor can be used to determine whether RGBA cursors are supported; displayGetDefaultCursorSize and displayGetMaximalCursorSize give information about cursor sizes.

On the X backend, support for RGBA cursors requires a sufficently new version of the X Render extension.

cursorNewFromName

Arguments

:: GlibString string

=> Display

display the Display for which the cursor will be created

-> string

name the name of the cursor

-> IO (Maybe Cursor)

return a new Cursor, or Nothing if there is no cursor with the given name

Creates a new cursor by looking up name in the current cursor theme.

cursorNewForDisplay

Arguments

:: Display

display the Display for which the cursor will be created

-> CursorType

cursorType cursor to create

-> IO Cursor

return a new Cursor

Creates a new cursor from the set of builtin cursors.

cursorGetDisplay

Arguments

:: Cursor

cursor Cursor

-> IO Display

return the Display associated to cursor

Returns the display on which the GdkCursor is defined.

cursorGetImage

Arguments

:: Cursor

cursor Cursor

-> IO (Maybe Pixbuf)

a Pixbuf representing cursor, or Nothing

Returns a Pixbuf with the image used to display the cursor. Note that depending on the capabilities of the windowing system and on the cursor, GDK may not be able to obtain the image data. In this case, Nothing is returned.
