WATCHING MYSELF
好快一个周过去了，这个周又学了不少东西，之后可能会多开几个板块来介绍MoBu。在Help & Document中提到了Motionbuilder的文档比较稀少，而最新的一版也是2009年的版本，百度谷歌都很难找到相应的个人文档，于是我便去MotionBuilder SDK Help中翻了一翻，发现相应的例子库还是比较丰富的，我就整理了一下，这几天会优先向大家分享Motionbuilder里面的UI模块！顺便补一下之前PyQt的坑

一、ArrowButton

ArrowButton is Arrow with Button

来看一下UI效果！

UI效果

由此可以实现部分的下拉菜单的功能，官方文档代码如下：

def PopulateLayout(mainLyt):
    anchor = FBAttachType.kFBAttachTop
    anchorRegion = ""
    for i in range(3):
        lytName = "Border" + str(i)
        lyt = FBLayout()
        x = FBAddRegionParam(10, FBAttachType.kFBAttachLeft, "")
        y = FBAddRegionParam(10, FBAttachType.kFBAttachTop, "")
        w = FBAddRegionParam(200, FBAttachType.kFBAttachNone, "")
        h = FBAddRegionParam(200, FBAttachType.kFBAttachNone, "")
        lyt.AddRegion(lytName, lytName, x, y, w, h)
        lyt.SetBorder(lytName, FBBorderStyle.kFBStandardBorder, True, True, 1, 0, 90, 0)

        arrowName = "ButtonArrow" + str(i)
        x = FBAddRegionParam(10, FBAttachType.kFBAttachLeft, "")
        y = FBAddRegionParam(10, anchor, anchorRegion)
        w = FBAddRegionParam(0, FBAttachType.kFBAttachNone, "")
        h = FBAddRegionParam(0, FBAttachType.kFBAttachNone, "")
        mainLyt.AddRegion(arrowName, arrowName, x, y, w, h)

        b = FBArrowButton()
        mainLyt.SetControl(arrowName, b)

        # important : we set the content AFTER having added the button arrow
        # to its parent layout
        b.SetContent("A layout border" + str(i), lyt, 250, 250)
        anchor = FBAttachType.kFBAttachBottom
        anchorRegion = arrowName

    # dummy label to show the layout moves
    x = FBAddRegionParam(10, FBAttachType.kFBAttachLeft, "")
    y = FBAddRegionParam(10, FBAttachType.kFBAttachBottom, arrowName)
    w = FBAddRegionParam(100, FBAttachType.kFBAttachNone, "")
    h = FBAddRegionParam(25, FBAttachType.kFBAttachNone, "")

    l = FBLabel()
    l.Caption = "Dummy label!"
    mainLyt.AddRegion("DummyLabel", "DummyLabel", x, y, w, h)
    mainLyt.SetControl("DummyLabel", l)


def CreateTool():
    # Tool creation will serve as the hub for all other controls
    t = FBCreateUniqueTool("Arrow Button Example")
    PopulateLayout(t)
    ShowTool(t)


CreateTool()

其中有部分注释，就不需要我解释了，拿到编辑器，执行一下试一试，再decomposition and refactor，理解其中函数的意义！

二、结语

这里展示了其中的一个例子

之后我会把整理好的例子集发出来

同时尽量更新完这个板块

做到体系化和模块化

同时同步更新其他板块的内容

共勉！
