| Methods
|
|
| cursorNewFromPixmap |
| :: 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.
|
|
|
| cursorNewFromPixbuf |
| :: 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 |
| :: 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 |
| :: 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 |
|
|
| cursorGetImage |
| :: 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.
