I got stuck while trying to implement Drag and Drop in gwidgets.
I hoped the following code would call the handler function and thus
print something to the console.
But it does not. ISo suppose I do not understand some basic
properties of the handler mechanism.
Can someone explain?
w <- gwindow()
lab = glabel("drag me",container=w)
ed = gedit("drop here",container = w)
adddropsource(lab)
adddroptarget(ed, handler=function(h,...) print("arrived"))
Thanks,
Mark
