Examples
========

Basic example
-------------

Source code : ::

 import guidata
 _app = guidata.qapplication() # not required if a QApplication has already been created
 
 import guidata.dataset.datatypes as dt
 import guidata.dataset.dataitems as di
  
 class Processing(dt.DataSet):
     """Example"""
     a = di.FloatItem("Parameter #1", default=2.3)
     b = di.IntItem("Parameter #2", min=0, max=10, default=5)
     type = di.ChoiceItem("Processing algorithm",
                          ("type 1", "type 2", "type 3"))
      
 param = Processing()
 param.edit()

Output :

Assigning values to data items or using these values is very easy : ::

 param.a = 5.34
 param.type = "type 3"
 print "a*b =", param.a*param.b


Other examples

A lot of examples are available in the `guidata` test module ::

    from guidata import tests
    tests.run()
