Text input reset focus

[Kurt Dally]

I'm working with a TextInput widget and can't figure out why all the below works, except the last line.  I am using the Enter Key on the keyboard and I lose focus every time I hit "Enter", read about this a bit in the docs, yet the last line I thought would bring the focus back.


def on_text_validate(self):

        self.ids.lbl0.text = self.prog.takeTest02(self.ids.inpt0.text)
        self.ids.inpt0.text = ""
        self.ids.inpt0.focus = True

The focus for the TextInput hasn't yet been lost by the time you set it again.

You should reset the focus in a function delayed till next frame so the focus is reset after you loose it.

Clock.schedule_once(self._refocus_ti)

def refocus_ti(self,*args):

   self.ids.inpt0.focus = True

Best Regards

Hello ZenCode,

issue is: I am able clear the testInput, but cursor is not focusing in the TextInput.

if you copy mode code and execute, it is allowing to enter the TextInput, after pressing RELOAD button, text in textInput is clearing but cusor is not focusing in the textInput.

could you pls help me by correcting my code to make sure refocus in TextInput after RELOAD.

thanks
