@class wxCursor
|
|
|
|
A cursor is a small bitmap usually used for denoting where the mouse
|
|
pointer is, with a picture that might indicate the interpretation of a
|
|
mouse click. As with icons, cursors in X and MS Windows are created in a
|
|
different manner. Therefore, separate cursors will be created for the
|
|
different environments. Platform-specific methods for creating a wxCursor
|
|
object are catered for, and this is an occasion where conditional
|
|
compilation will probably be required (see wxIcon for an example).
|
|
|
|
A single cursor object may be used in many windows (any subwindow type).
|
|
The wxWidgets convention is to set the cursor for a window, as in X, rather
|
|
than to set it globally as in MS Windows, although a global wxSetCursor()
|
|
function is also available for MS Windows use.

@section cursor_custom Creating a Custom Cursor
|
|
|
|
The following is an example of creating a cursor from 32x32 bitmap data
|
|
(down_bits) and a mask (down_mask) where 1 is black and 0 is white for the
|
|
bits, and 1 is opaque and 0 is transparent for the mask.
|
|
It works on Windows and GTK+.

- under Windows, it defaults to @c wxBITMAP_TYPE_CUR_RESOURCE.

Other permitted types under Windows are @c wxBITMAP_TYPE_CUR

(to load a cursor from a .cur cursor file) and @c wxBITMAP_TYPE_ICO
|
|
(to load a cursor from a .ico icon file).
|

- under MacOS, it defaults to @c wxBITMAP_TYPE_MACCURSOR_RESOURCE;

when specifying a string resource name, first the color cursors 'crsr'

and then the black/white cursors 'CURS' in the resource chain are scanned

through. Note that resource forks are deprecated on OS X so this
|
|
is only available for legacy reasons and should not be used in

new code.
|
|
- under GTK, it defaults to @c wxBITMAP_TYPE_XPM.
|
|
See the wxCursor(const wxImage& image) ctor for more info.

- under X11, it defaults to @c wxBITMAP_TYPE_XPM.

- under Motif, it defaults to @c wxBITMAP_TYPE_XBM.
