I don't get it why you create two windows with duplicate callbacks which in fact
share same window procedure...what is the point in all this
there is no need for that at all...

[kryton9]

Well for example in a game:
The one windows could be the main game action screen.
The second window a map of the world you are in and your location.

[Charles Pegge]

I have never seen that before Frank. Intriguing idea, 2 main windows operating at the same time.

You only need one loop to service both windows at the same time, but to get them to quit independently, a little extra logic is required:

 sys bRet,bRet2,xit
  '
  do
    bRet = GetMessage (@wm, 0, 0, 0)
    if not bRet
     xit++
      if xit=2 then exit do
    elseif bRet = -1
      print "message loop error"
    else
      TranslateMessage @wm
      DispatchMessage @wm
    end if
  end do

[Frankolinox]

more to come with my idea and a project next weeks and month if there's time enough..

one example could be to use "drag'n'drop" feature for folder's, material, maps (game as kent said), images or even appliacation (depending or not from the main window where you're working) and so on from one sdk window to another and much more.

I've not tested my idea yet, but there should be interaction between this two (you can create four, five windows more if you like) sdk windows in future.

[Frankolinox]

can anybody test this "three sdk windows" similar if the winmain() message loops are correct?

[Frankolinox]

no answer does that means, a) you don't know it or b) it's ok my three sdk window oxygen example? or c) no fun to answer ?

[Charles Pegge]

Try removing the second and third message loops.

sorry Frank...
this is not good solution as i said before
