Hi nozkan,

What is error in my code ?

1. Your program starts with focus on self.my_button.
2. You bind the 'my_choice'-widget with with the 'my_choice_on_focus'-
method.
3. By clicking on 'my_choice' the focus change from 'my_button' to
'my_choice'. Thereby the 'my_choice_on_focus'-method was entered.
4. Remember: The focus is on 'my_choice'.
5. After 'my_choice_on_focus'-method is processed, the focus is yet on
'my_choice' and you skip to 4.

If you set focus back on 'my_button', after the 'my_choice_on_focus'-
method is processed, the program is doing what you want.

I'm sorry for my English. I know it isn't good.

if my_choice to be focus first program starts with error message
This code is part of my orginal code for show error in my orginal code
I want to insert my_choice items when my_choice is selected.
Because items not same always.
I take items on a database with a query in my orginal code.

Hi nozkan,

What is error in my code ?

  1. Your program starts with focus on self.my_button.

  2. You bind the ‘my_choice’-widget with with the ‘my_choice_on_focus’-

method.

  1. By clicking on ‘my_choice’ the focus change from ‘my_button’ to

‘my_choice’. Thereby the ‘my_choice_on_focus’-method was entered.

  1. Remember: The focus is on ‘my_choice’.

  2. After ‘my_choice_on_focus’-method is processed, the focus is yet on

‘my_choice’ and you skip to 4.

If you set focus back on ‘my_button’, after the ‘my_choice_on_focus’-

method is processed, the program is doing what you want.

I’m sorry for my English. I know it isn’t good.
