WtMainLoop Function

Handles the dispatching of events.

Usage

status = WtMainLoop( )

Input Parameters

None.

Output Parameters

None.

Returned Value

status — One (1) indicates success; zero (0) indicates failure.

Keywords

Noblock — If specified and nonzero, events are dispatched in the background, and WtMainLoop returns immediately to process PV‑WAVE commands from the command line.

Discussion

The WtLoop function can be called to accomplish the same result as WtMainLoop. WtMainLoop has been retained to provide upward compatibility with an earlier release of PV‑WAVE, but it is recommended that you use WtLoop, instead.

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.
