From what I understand, a delegate is a function that gets called whenever it's action occurs. I have my function, but it's not being called. Here's what I have:
class myclass():
ig=ui.load_view('myview')
tv=ig['textview1']
def textview_did_change(self, textview):
print'hi'
How would I properly implement my delegate?
@Brian, delegate is not a function, but a class.
Check this:
import ui, console
class Delegate:
def textview_did_change(self, textview):
console.hud_alert("textview_did_change!")
view = ui.View()
textview = ui.TextView()
textview.delegate = Delegate() # This is the line you are looking for
textview.flex = "WH"
view.add_subview(textview)
view.present("fullscreen")
@ShadowSlayer
Could you provide an example of how to do this while using ui.load_view()?
I can't seem to get it working.
In your example, you would use
tv.delegate=Delegate()
Where you implemented Shadow's Delegate class example.
@Brian, read the docs :)
When you use ui.load_view(), it returns a ui.View object. In the UI editor you can select your textview element and set it's name to something like "mytextview". Then you can use textview = view["mytextview"].
Check this:
import ui
...
view = ui.load_view("uifile")
textview = view["mytextview"]
textview.delegate = Delegate()
...
When I append text to the text box, the delegate is not called even when I have it properly configured. Is this intentional or is it a bug? Also thanks for the help, much was learned.
@Brian, do you mean my example? If you are talking about your code, could you please post it so I can take a look and maybe find out the problem?
