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 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 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.
