This message has 2 questions:
First, I have a question about the way that Performer handles events..
We are trying to implement a browser plugin version of our software that
uses an X window created by Netscape to draw into.. I added the
following to the InitPipe() function in perfly:
pw->setWSWindow((pfWSConnection)display, (pfWSWindow)window);
pw->setSize(width, height);
This effectively uses the Netscape window for drawing..
(kind of cool.. see http://www.openworlds.com/images/plugin.jpg)
However we are unable to process any events (Keyboard, Mouse, Expose,
etc), even after calling:
pfuInitInput(ViewState->masterChan->getPWin(), ViewState->input);
So I took a look at the libpfutil code (input.c), and it is using
XEventsQueued() and XNextEvent() to get the events.. It looks like the
events aren't properly queued...
However, I was able to call XtAddRawEventHandler() to register a
callback that prints a message whenever events occur.. All of the normal
events are occuring as expected.. Any ideas why I can register a
callback to receive events, but Performer's XEventsQueued() and
XNextEvent() calls don't work?
Second question: We have been working on a Linux VRML loader..
Currently it is working well, but only handles properly sized rgb
textures... I am looking for examples on how to decode and scale
images.. Our IRIX version uses IFL/IL, but I am looking to move to a
more portable solution... (Anyone interested in the Linux VRML loader,
email me privately)..
Thanks in advance!
Bryan
