[Insight-users] Silly FLTK/ITK Question

[Zein Salah]

> Hello everybody,
> 
> I have an ITK application that has an FLTK main windows as user interface. A "Load Image" buttom 
> on this main window should pop up a new window for loading a MetaImage file (choose file name, 
> preview, etc.). 
> 
> The problen is: The main window does not wait for the file-loading-window to finish, and continues
> before a file has been loaded. I would like that the main window suspend until the file-loading-window
> is closed, i.e. until I am sure that a valid image has been loaded.
> 
> Please, what is the trick for doing this?
> 
> Much thanks,
> Zein
