我使用PanelSet
类创建一个由两个面板组成的设置屏幕:
panelA
显示整体设置选项列表panelB
显示在右侧,包含panelA
上每个项目的不同选项列表当用户更改Panel
上的焦点项目时,如何替换右侧显示的panelA
?
Roku's documentation声明您必须使用方法replaceChild
,但我无法弄清楚它应该如何工作,或者任何示例。这就是我的尝试,但它不起作用:
function showPanelInfo()
if m.panelA.list.itemFocused = 0
m.panelset.replaceChild(m.panelB, 3)
else
m.panelset.replaceChild(m.panelC, 3)
end if
end function
Function init()
m.panelset = createObject("roSGNode", "PanelSet")
' Left-hand side panel with two items list
m.panelA = m.panelset.createChild("OptionsListPanel")
' Right-hand side panels with different lists for each item on left-hand side panel
m.panelB = m.panelset.createChild("OptionsBPanel")
m.panelC = createObject("roSGNode", "OptionsCPanel")
m.panelA.list.observeField("itemFocused", "showPanelInfo")
...
end function
答案 0 :(得分:0)
面板集没有nextPanel
。仅列表面板和网格面板具有m.panelA.nextPanel = m.panelB
。因此,
Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button2.Click
Dim My_Thread as Threading.Thread
My_Thread = New Threading.Thread(AddressOf Module1.MyTest)
My_Thread.Start()
End Sub
