Throughout: assorted docs
* gdk/gdkwindow.h: deprecate gdk_window_set_hints(), it's broken,
gdk_window_set_geometry_hints() should be used instead.
* gdk/gdkimage.h: deprecate gdk_image_ref, gdk_image_unref, and
document them
* gdk/x11/gdkx.h: remove gdk_get_client_window() since it doesn't
seem to exist in any .c files
* gdk/x11/gdkcolor-x11.c (gdk_colormap_query_color): docs,
g_return_if_fail (pixel < colormap->size).

/**
|
|
* gdk_cursor_new:
|
|
* @cursor_type: cursor to create
|
|
*
|
|
* Creates a new cursor from the set of builtin cursors.
|
|
* Some useful ones are: #GDK_RIGHT_PTR (right-facing arrow),
|
|
* #GDK_CROSSHAIR (crosshair), #GDK_IBEAM (I-beam), #GDK_WATCH (busy),
|
|
* #GDK_FLEUR (for moving objects), #GDK_HAND (a pointing hand),
|
|
* #GDK_LEFT_SIDE (resize left side), #GDK_RIGHT_SIDE (resize right side),
|
|
* #GDK_TOP_LEFT_CORNER (resize northwest corner), #GDK_TOP_RIGHT_CORNER (resize
|
|
* northeast corner), #GDK_BOTTOM_LEFT_CORNER (resize southwest corner),
|
|
* #GDK_BOTTOM_RIGHT_CORNER (resize southeast corner),
|
|
* #GDK_TOP_SIDE (resize top side), #GDK_BOTTOM (resize bottom side),
|
|
* #GDK_SB_H_DOUBLE_ARROW (move vertical splitter),
|
|
* #GDK_SB_V_DOUBLE_ARROW (move horizontal splitter).
|
|
*
|
|
* To make the cursor invisible, use gdk_cursor_new_from_pixmap() to create
|
|
* a cursor with no pixels in it.
|
|
*
|
|
* Return value: a new #GdkCursor
