[Gambas-user] ProgressBar Change Event

[Fabien Bodard]

But There is an ENORMOUS difference between a textbox and a progressbar !!

In the progressbar side the user CAN'T change the value with his
keyboard or mouse. So we know where and when the value is changed.

The change event in the text box is a way to inform the program that
the user do something.

You need really to explain us why you really need this event !!


i think it's not a real need because


Public sub SpinBow_Change()
  Progressbar1.Value = Last.value/100
End


Public sub ProgressBar1_Change()
  If last.Value =1 then message.info("end process")
End


is more complicated (for the same result) than :

Public sub SpinBow_Change()
  Progressbar1.Value = Last.value/100
  If last.Value =100 then message.info("end process")
End


no ?

I really don't understand why you need to test the progressbar ? and
not check on the value that set the progressbar... you need to
learn the data/view way of programming. Datas are one thing , View
another ! ProgressBar is just a view for a state... but does not
store the state.
