Remove widget

[Sergey Utkin]

Hi,
I want to add / remove a widget, depending on the MultiSelect, add I got, but how to remove it?

class Form1(npyscreen.ActionFormV2):

    btn = None
   
    def create(self):
        self.keypress_timeout = 1
        self.Name = self.add(npyscreen.TitleText, name = u'Test:')
        self.Check = self.add(npyscreen.MultiSelect,  max_height=2, values = ["Пульт"], scroll_exit=True, width=20)
       
       
    def beforeEditing(self):
        if self.HostID == 0:
            self.Name.value = ""
           
    def while_waiting(self):
        if self.btn is None:
            if len(self.Check.value) != 0:
                self.btn = self.add(btn, name = u"Add",color='STANDOUT')
            else:

???

P.S. sorry for my english.

Hi Sergey,

The usual way to do this is not to keep adding and removing the
widget, but to use the the .hidden attribute.

Also, have a look at FormControlCheckbox - which you can use to
control which widgets appear or not.
