WtPointer Function
The pointer utility function.
Usage
status = WtPointer(function, widget[, parameters])
Parameters
function:
'GetLocation' — Get the current location of the pointer.'GetControl' — (Motif only) Get the control attributes of the pointer.'GetMapping' — (Motif only) Get the current mapping of the pointer.'SetLocation' — (Motif only) Set the location of the pointer.'SetControl' — (Motif only) Set the control attributes of the pointer.'SetMapping' — (Motif only) Set the mapping of the pointer.widget — The current widget.
parameters:
'GetLocation' — A seven-element array of long integers:0 — Root window1 — Child window where the pointer is located2 — X coordinate in root3 — Y coordinate in root4 — X coordinate in current window5 — Y coordinate in current window6 — Modifier keys and buttons state mask'GetControl' — A three-element array of long integers:0 — accel_numerator1 — accel_denominator2 — threshold'GetMapping' — An array of up to ten long integers:0–9 — Pointer button mapping'SetLocation' — A two element array of long integers: 0 — X coordinate in current window1 — Y coordinate in current window'SetControl' — A three-element array of long integers: 0 — accel_numerator1 — accel_denominator2 — threshold'SetMapping' — An array of up to ten long integers:0–9 — Pointer button mappingReturned Value
status — One (1) indicates success; zero (0) indicates failure.
Discussion
See the Xlib Reference Manual (O'Reilly & Associates, Inc., 1989) for details on XQueryPointer, XGetPointerControl, XGetPointerMapping, XWarpPointer, XChangePointerControl, and XSetPointerMapping.
note | Rogue Wave has ported a subset of the Widget Toolbox (Wt) functionality that is available for Motif to Microsoft Windows. Because the Widget Toolbox under Windows is not a complete implementation, we recommend that Windows developers use the PV‑WAVE Widgets (Ww) layer or the VDA Tools when developing GUI applications. |
Example
.
.
status=WtPointer("GetLocation", wid, state).
