XRecolorCursor(3)


NAME

   XRecolorCursor, XFreeCursor, XQueryBestCursor - manipulate cursors

SYNTAX

   int XRecolorCursor(Display *display, Cursor cursor, XColor
          *foreground_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 heightof the cursor that you want the
             size information for.

   width_return
   height_return
             Return the best width and height that is closest to the
             specified 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
   cursors 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
             Window or Pixmap.
