Auto-close canvas
Been trying this for 2 hours now. Have a slideshow, and am replacing a messagedialog over each slide with an image canvas to make it look better. If you leave the info-canvas open it conflicts with the screensaver in that pressing a button to end the screensaver doesnt clear the screensaver, and shows the info-canvas - ugly. I tried closing the canvas in the screensaver function with a .Close() and with a separate function but it didnt seem to want to do that. So - i figure I'll put a close on the canvas with a sleep() timer. But i cant figure out where to put it where it doesnt stop something else from working. Have tried in the loop, out of the loop before and after, in its own loop, in a while inside the other while. Perhaps someone could point out where it ought to go. i'd sure appreciate it.
Function InfoCanvas(slideshow, infotype As Integer, curr_photo As Object, icanvas)
icanvas = CreateObject( "roImageCanvas" )
icanvas.setmessageport(createobject("romessageport"))
...........(canvas content)
icanvas.SetLayer( 1, [ url, text2, text3, text ] )
icanvas.Show()
slideshow.Pause() '' important function
GetURL_Image(curr_photo) '' important function
while true
msg = wait(0,icanvas.getmessageport())
if msg.isbuttonpressed()
button = msg.getindex()
print "Info Button ";button;" pressed"
if button = 4
slideshow.Resume()
return button
end if
end if
..........(other buttons)
if msg.isRemoteKeyPressed()
if msg.GetIndex() = 2
return 0
end if
end if
end while
End function

Re: Auto-close canvas
Why not just implement the whole slideshow in imagecanvas instead of trying to using image canvas on top of the slideshow? That way, you can just use SetLayer to put your dialog on the topmost layer.

Re: Auto-close canvas
Thanks for replying Joel, the short answer is that I've been developing for all of two months now and the idea of building a slideshow from scratch is a little beyond me and considering you all have provided us with slideshow component and I'm not unhappy with it, it doesn't seem necessary.
If you'd like to take a stab a how i can close that canvas layer after some minutes without screwing up the other functions, or even better why i cant close it from the screensaver functions even though the right variable is present i'd be grateful.
