Hi.
So currently I just want to set focus on item in GridScreen after DetailsScreen was closed. I have two rows in GridScreen with 20 items, when you press OK on items, you will see DetailsScreen, but it is possible to change target item in the DetailsScreen by clicking left/right buttons. So the problem is that when I press "back" in the DetailsScreen, I want my last item i saw in DetailsScreen to be focused on the GridScreen.
I have template HideScreen() method in my HomeScreen
Sub HideScreen(node as Object)
if node = invalid OR (m.screenStack.peek() <> invalid AND m.screenStack.peek().isSameNode(node))
last = m.screenStack.pop()
prev = m.screenStack.peek()
last.wasClosed = true
last.visible = false
if prev <> invalid
prev.focusedChild.jumpToRowItem = [0,m.detailsScreen.itemSelectedPosition]
prev.visible = true
prev.setFocus(true)
end if
end if
End Sub
So when I trying to use prev.focusedChild.jumpToRowItem I get runtime error like this one:
Invalid value for left-side of expression.
Here is prev:
Brightscript Debugger> ?prev
<Component: roSGNode:GridScreen> =
{
childRenderOrder: "last"
clippingRect: <Component: roAssociativeArray>
enableRenderTracking: false
inheritParentOpacity: true
inheritParentTransform: true
muteAudioGuide: false
opacity: 1
renderPass: 0
renderTracking: "disabled"
rotation: 0
scale: <Component: roArray>
scaleRotateCenter: <Component: roArray>
translation: <Component: roArray>
visible: false
change: <Component: roAssociativeArray>
focusable: false
focusedChild: <Component: roInvalid>
id: "GridScreen"
content: <Component: roSGNode:ContentNode>
focusedContent: <Component: roSGNode:ContentNode>
itemFocused: <Component: roArray>
itemFocusedIndex: <Component: roArray>
rowItemSelected: <Component: roArray>
}
I also tried to observe and then use GridScreen field and set it onChange m.rowList.jumpToItem =..., but it is not working at all.
What am I doing wrong here?
