DIAGNOSTICS

BadMatch An InputOnly window is used as a Drawable.

BadDrawable
A value for a Drawable argument does not name a defined Window or Pixmap.

BadMatch The values do not exist for an InputOnly window.

BadValue Some numeric value falls outside the range of values accepted by the request. Unless a specific range is specified for an argument, the full range defined by the argument’s type is accepted. Any argument defined as a set of alternatives can generate this error.
