Unfortunately, the Forum has mangled your code’s indentation, so it’s not clear what’s going on. To prevent that, put
``` python
on a line by itself before your code, and
```
on a line by itself after your code. Then we’ll have more clues to follow.

Edit: also, please be specific about

  1. the steps you’re following,
  2. what you expect to happen, and
  3. what happens (or doesn’t happen) instead.

Hi and welcome!

So, imagine that you open your form with the text box not visible, so perhaps in your init you might have:

self.mytextbox.visible = False

Then you might have a click event on your button, like:

def mybutton_click(self,**args):

   self.mytextbox.visible = True

And that’s it really!

Hello and welcome @Alec.W!

If you would like to have the button set up so, whenever you click it, it changes the text_box’s visibility, then here is an example:

def button_1_click(self, **event_args):
    """This button changes the text_box_1 visibility status"""
    self.text_box_1.visible = False if self.text_box_1.visible else True

If you are still having problems, then please share a clone of your app, so we can have a better understanding.
