XRecolorCursor, XFreeCursor, XQueryBestCursor - manipulate cursors
SYNOPSIS
XRecolorCursor(display, cursor, foreground_color, background_color)
Display *display;
Cursor cursor;
XColor *foreground_color, *background_color;
XFreeCursor(display, cursor)
Display *display;
Cursor cursor;
Status XQueryBestCursor(display, d, width, height, width_return,
height_return)
Display *display;
Drawable d;
unsigned int width, height;
unsigned int *width_return, *height_return;
ARGUMENTS
Specifies the RGB values for the background of the source. Specifies
the cursor. Specifies the drawable, which indicates the screen. Spec‐
ifies the connection to the X server. Specifies the RGB values for the
foreground of the source. Specify the width and height of the cursor
that you want the size information for. 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 cur‐
sors on displays that cannot support large ones.
XQueryBestCursor can generate a BadDrawable error.
DIAGNOSTICS
A value for a Cursor argument does not name a defined Cursor. A value
for a Drawable argument does not name a defined Window or Pixmap.
