Date: Sat, 15 Jan 2005 02:01:51 +0000 (UTC) From: jimrandomh Subject: [SDL] Re: Modifier keys pressed during initialization stick I wrote a simple test program which initializes SDL, prints the SDL version number, then prints any keydown and keyup events with their modifiers. (Source code below). Compilation was done using Visual Studio 6, release mode. My test sequence was: Start a command prompt. Type the name of the test program. shift down enter down (program starts) Wait for window to appear enter up shift up spacebar down spacebar up Under Windows 98, the output was correct: SDL 1.2.8 left shift down shift-return down shift-return up left shift up space down space up Under Windows 2000 and under Windows XP, the output was: SDL 1.2.8 shift-space down shift-space up Since shift was not held at the time space was pressed, this is incorrect. Similar results were observed with launching in different ways (including double-clicking in Windows Explorer), so it does not depend on the launching terminal.

.SH "NAME"
SDL_PumpEvents\- Pumps the event loop, gathering events from the input devices\&.
.SH "SYNOPSIS"

\fBvoid \fBSDL_PumpEvents\fP\fR(\fBvoid\fR);
.SH "DESCRIPTION"
.PP
Pumps the event loop, gathering events from the input devices\&.
.PP
\fBSDL_PumpEvents\fP gathers all the pending input information from devices and places it on the event queue\&. Without calls to \fBSDL_PumpEvents\fP no events would ever be placed on the queue\&. Often calls the need for \fBSDL_PumpEvents\fP is hidden from the user since \fI\fBSDL_PollEvent\fP\fR and \fI\fBSDL_WaitEvent\fP\fR implicitly call \fBSDL_PumpEvents\fP\&. However, if you are not polling or waiting for events (e\&.g\&. your filtering them), then you must call \fBSDL_PumpEvents\fP to force an event queue update\&.

\fBNote:

You can only call this function in the thread that set the video mode\&.
