The parameters srow, scol, erow, ecol mark the upper left and lower right corners of the display box, provided that flags contains the option XTF_XYXY. Otherwise, they are interpreted as row, col, strow, endrow as in PCKLST. Note that since this XTREE supports horizontal scrolling and column resizing, the width of the display box is independent of the width of the data. Also note that the coordinates are relative to the main window or dialog, or to the control specified by XTR.PARENTID.
