[Laszlo-user] DHTML

Thu Dec 13 14:41:07 PST 2007

The DHTML runtime is pretty reliable, yes -- but video won't work in  
DHTML, because video uses Flash APIs, which just aren't available in  
DHTML. The way to support this is to use the <html> tag to embed  
arbitrary html, including a video player, but I don't think we've  
figured out exactly how to make inter-application communication work  
in that setup.

DHTML support is better in the nightly builds of trunk than in 4.0.7.  
You're at the evaluation stage, so I recommend you use a recent  
nightly of trunk:
http://download.openlaszlo.org/nightly/trunk/7530

For working with SOLO, I recommend downloading the zip file, then  
unzipping it onto your server. The lps directory is definitely  
necessary -- it contains all the laszlo framework code. Without the  
lps directory, you've just got your source compiled to object code,  
but no support libraries to link to (if I can use an old-school  
compiler analogy).

You are figuring stuff out well, and making good progress. You are  
also asking good questions. Keep going!
