I am now busy making the GUI for my camera calibration tool. I have chosen to use wx for the GUI. So far it has been nice to use. the documentation is quite good and the development is going nicely. It does have some weird things. I had a problem creating things at time if i try to set them to a variable, but work fine when i just declare them. My biggest problem has been creating a window with a scroll bar. that should be that hard, but for some reason I cant get it to work. My ScrolledWindow just refuses to show up. So i had settled for scaling down the images to fit the display panel. Seeing as the GUI is not the main issue for the unversity it will have to do for now
