MWAPI - POS

Draft MDC Standard

POS specifies the position of the origin of the window frame, expressed in the unit of measure defined by the unitspec component of the pos value, if present, or by the window’s UNITS wattribute otherwise.

If the window’s TIED wattribute is TRUE, the position is relative to the origin of the viewport of the window’s parent. If the unit of measure is CHAR, the basis font is the font specified by the parent’s FFACE, FSIZE and FSTYLE wattributes. If the unit of measure is REL, the basis size is the size of the parent’s viewport when the parent is created.

If the window’s TIED wattribute is FALSE, the position is relative to the origin of the display. If the unit of measure is CHAR, the basis font is the font specified by the FFACE, FSIZE, and FSTYLE dattributes for the display on which the window appears. If the unit of measure is REL, the basis size is the size of the display.

When an application assigns a value to the POS wattribute of an existing window, if hpos or vpos is not specified then the horizontal or vertical position of the window, respectively, is not altered.

For a window that is iconic, the effect of assigning a value to POS is platform dependent.
