How do you change focus out of a grid to another item?

I am learning SceneGraph and I have been modifying the SimpleGridWithDetailsAndVideo. I am now trying to add a search feature.

In case you are not familiar with this sample project, the screen I am working with, GridScreen.xml is just a grid of items. I have added a ButtonGroup with a search icon button at the top left corner of the screen.

How do I change focus from my grid or RowList to the image at the top? :?:

Do I need to put the grid and button in some parent other than the Group component that they are currently in ? :?:

Thank you for taking the time to read this. Any information that you can provide no matter how minor will be very appreciative. :slightly_smiling_face:

I don’t know if there may be other (better? easier?) ways to do this but you can certainly add an “onKeyEvent” function in your GridScreen.brs something like this:

Function OnKeyEvent(key, press) as Boolean
    result = false
    if press then
        if key = "up" and m.button.hasFocus() = false
            m.button.setfocus(true)
            result = true
        else if key = "down" and m.button.hasFocus() = true
            m.rowlist.setfocus(true)
            result = true
        end if
    end if
    return result
End Function

(Note: this assumes you’ve done a findNode on your button to set m.button)

Thank you so much. :grinning_face_with_smiling_eyes:

I tried putting the SetFocus in the init just to test it but it didn’t work. Putting it in the OnKeyEvent did the trick.

I am so grateful for such a helpful community. :slightly_smiling_face:
