Hi Anne,
In the aspects method “initial map” (the instance tab of your class holding
the interface) you can add conditions
So you could have a initialMap value ifTrue:[“change the default value of
the other parameters]
Don’t forget the “value” method because initialMap is a valueHolder and not
the value itself.
Then you might have the problem that the value of the crop cover parameters
will not refresh automatically.
I personally never found a very nice method to refresh a window.
I use tricks such as:
(self dependents detect: [:d | d label = 'Water Result'])
refresh.
or for images self class anImage displayOn: ((self dependents detect: [:d
| d label = ' Water Result ']) graphicsContext) at: (Point x:30 y:30) ]
Another way is of course to have your crop cover parameters in another
window. In such case you just need to add a button in the same interface as
initialMap, that opens the crop cover parameters interface.
Hope that helps
Nicolas

Subject: [cormas] User-interface update
Hi all,
I'm building an input interface (with GUI Painter Tool) that displays all
the parameters of the model with their default values that end-users can
possibly modify. Attached is the bit I'm struggling with.
If the user selects "map_1986" in the "Initial Map" list, then it's fine,
the default parameters for "crop cover" are correct (30 and 50%).
However, if the user chooses "map_2005", then I'd like the interface to
instantly display another set of default parameters (50 and 70% for
example).
Any suggestion on how to do it?
Many thanks for your help
cheers
anne
