今天重新尝试构建了部分流程，看了一集海昏侯，挺好看

今天我们来看一下也是UI中非常常用的List

一、List

列表，以及下拉列表

我们来看一下UI效果

UI_效果

来直接看一下代码

    lyt.SetBorder("Border1", FBBorderStyle.kFBStandardBorder, True, True, 1, 0, 90, 0)

    lyt.OnInput.Add(OnInputCb)
    lyt.OnResize.Add(OnResizeCb)
    lyt.OnShow.Add(OnShowCb)
    # This is commented out because these callbacks run all the time
    # lyt.OnPaint.Add(OnPaintCb)
    # lyt.OnIdle.Add(OnIdleCb)

    mainLyt.AddRegion("Reg", "Reg", x, y, w, h)
    mainLyt.SetControl("Reg", lyt)


def CreateTool():
    # Tool creation will serve as the hub for all other controls
    t = FBCreateUniqueTool("Tool Layout")

    PopulateLayout(t)
    ShowTool(t)


CreateTool()

大家仔细研究一下代码上方的几个函数，敲一敲，decomposition and refactor!
