Dear OpenMeetings Developers,
From a menu item, we would like to load a PDF file to whiteboard from a
location on OpenMeetings server (say from "uploads" directory).
To do this, is it required to generate "fileHash" first? If yes or no,
then how to do it?
When we study the uploadWindowExplorer and fileUpload classes, all we
want to do is call the following:
canvas._drawarea.parent.parent.clearAreaAndAddImage(this.generateFileLink(tArrayValueObj.fileHash),0,0,
canvas.getUrl() +'DownloadHandler',
tArrayValueObj.fileHash,"videoconf1","/","files",hib.conferencedomain);
Can we call this directly from our Menu button, and how to get a
fileHash for the file we placed in uploads directory. Can we avoid using
"tArrayValueObj" for this task?
What is the role of "onCompleteByRemote", is it irrelevant in this case?
Sincerely,
--
