Hi there. I'm modifying an old API-Style program and want to compile it with the new OpenGL-Haskell-API. In the past one defined a subwindow in the following way: uniW<- createSubWindow mainW (WindowPosition space space) (WindowSize 600 400) Now the parameters are away. You define a normal window by setting the statevars and create one. initialWindowSize $= Size 100 100 initialWindowPosition $= Position 100 100 createWindow progName Whats about subwindows? What have to be done if you want to create a subwindow at position 50,50 relatively to mainwindow with a specific size? And how does the reshaping of subwindows work? If you resize your mainwindow, the mainreshape is called with the new size. When and with what size is the subwindow reshapecallback-func called by OpenGL? Or am I forced to call it by myself in the mainreshape? Greetings Patrick
