Well, here's some good news about font loading and some not particularly good news about image asset loading.
I modified the LPS import compiler to add fonts into the loadable library, and added an ImportAssets tag to it, and the main app can now load fonts dynamically, just as in Sebastian's example. I guess ImportAssets, in addition to importing individual definitions, also just imports all the fonts from a swf file. However, I also modified the compiler to add all library image resources to the loadable library swf, and put all of their exported names into the ImportAssets tag, and they were not visible at the top level like the definitions that are compiled into the main app, I couldn't attach them to views or display them. So there seems to still be an issue here, I am going to try experimenting with swfmill some more and see if I can get some loadable resources from one of it's files.

Hmm, the library file produced by swfmill seems to just have put a "importAssets" swf instruction at the end of it, which references the library file itself (by it's URL). I don't think I ever tried that when I was experimenting with the importAssets tag in the LPS; I tried putting it in the main app, which did sort of work but forced the library to get loaded at the same time as the main app was being loaded. I never thought to put the importAssets tag in the library, because I guess I figured it would load the assets into the child movieclip, and they still wouldn't be usable from the root movieclip. I'll play with this and see if I can get dynamically loaded resources to be attachable to views in the main app. On 1/29/07, Henry Minsky <[EMAIL PROTECTED]> wrote: > > OK I will take a look at integrating this, and try to figure out what > swf byte code is being used in the library. > > > On 1/28/07, Sebastian Wagner < [EMAIL PROTECTED]> wrote: > > > > hi, > > > > I have added some methods to LzFontManager but I would suggest to > > include such librarys in a more general way sothat other sharedLibrary's > > with images can be included and attached to loaded Library too. > > > > see attached i have tested it with legals: > > Files changed: > > $LPS_HOME/WEB-INF/lps/lfc/kernel/swf/Library.lzs > > $LPS_HOME/WEB-INF/lps/lfc/kernel/swf/LzFontManager.as > > $LPS_HOME/WEB-INF/lps/lfc/kernel/swf/LzDynamicLibraryLoader.as > > > > Test-Files: > > $LPS_HOME/test/dynamiclibrary/* > > $LPS_HOME/test/dynamiclibrary/fonts/* > > > > in the test-file (http://localhost:8080/legals/test/dynamiclibrary/loadfontslibrary.lzx ) > > it includes one font by native font control and the second one has to be > > loaded at runtime before creation of an textbox otherwise Debugger throws a > > *WARNING: Undefined font 'KentuckyFriedChickenFont'* > > > > note: > > 1.)
