I have been trying to create an application that responds to actions on the
server PC and pushes graphics to users who view a web interface. The device
hooked to the server machine is a tablet-type device, so I am trying to
generate a display of what a user writes on the tablet to all the connected
users.
So far, I have a paint canvas that I can put points on, but when I call
update() from my extension of WPaintedWidget to draw the active point on the
tablet, it clears the other points. I would like some way of having the
points persist on the user's screen in the browser so that they can see what
is drawn on the tablet. Using something like drawPoints with all the points
would be somewhat cumbersome since there will be lots of points being
painted, and I'm trying to do this in as close to real time as I can.
Any help would be appreciated.
