NAME
XRecolorCursor, XFreeCursor, XQueryBestCursor - manipulate cursors
SYNTAX
int XRecolorCursor(Display *display, Cursor cursor, XColor *fore-
ground_color, XColor *background_color);
int XFreeCursor(Display *display, Cursor cursor);
Status XQueryBestCursor(Display *display, Drawable d, unsigned int
width, unsigned int height, unsigned int *width_return, unsigned
int *height_return);
ARGUMENTS
background_color
Specifies the RGB values for the background of the source.
cursor Specifies the cursor.
d Specifies the drawable, which indicates the screen.
display Specifies the connection to the X server.
foreground_color
Specifies the RGB values for the foreground of the source.
width
height Specify the width and height of the cursor that you want the
size information for.
width_return
height_return
Return the best width and height that is closest to the spec-
ified width and height.
DESCRIPTION
The XRecolorCursor function changes the color of the specified cursor,
and if the cursor is being displayed on a screen, the change is visible
immediately. The pixel members of the XColor structures are ignored;
only the RGB values are used.
XRecolorCursor can generate a BadCursor error.
The XFreeCursor function deletes the association between the cursor
resource ID and the specified cursor. The cursor storage is freed when
no other resource references it. The specified cursor ID should not be
referred to again.
XFreeCursor can generate a BadCursor error.
Some displays allow larger cursors than other displays. The
XQueryBestCursor function provides a way to find out what size cursors
are actually possible on the display. It returns the largest size that
can be displayed. Applications should be prepared to use smaller cur-
sors on displays that cannot support large ones.
XQueryBestCursor can generate a BadDrawable error.
DIAGNOSTICS
BadCursor A value for a Cursor argument does not name a defined Cursor.
BadDrawable
A value for a Drawable argument does not name a defined Win-
dow or Pixmap.
