XQueryBestSize() can generate BadDrawable, BadMatch, and BadValue errors.
BadDrawable | A value for a Drawable argument does not name a defined Window or Pixmap. |
BadMatch | An InputOnly window is used as a Drawable. |
BadMatch | Some argument or pair of arguments has the correct type and range but fails to match in some other way required by the request. |
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. |
