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.
