一、Border

Border是指UI布局的分割线，即边界

来看一下UI效果

会看到有在Motionbuilder中有比较全或的border

这样在设置UI布局的时候有比较清晰的边界线，官方代码如下：

# Create a tool that shows how to specify attach in a FBLayout

# Tool creation will serve as the hub for all other controls
t = FBCreateUniqueTool("Attach Example")

b = FBButton()
b.Caption = "But"

# Create a button that is left justify
x = FBAddRegionParam(0,FBAttachType.kFBAttachLeft,"")

b2 = FBButton()

b3 = FBButton()
b3.Caption = "But3"

# Create a button that Right justify in the FBLayout.
# since the x Region param sets the left corner of the controls
# we need to offset the attach by -45 pixels so the button is shown.

b4 = FBButton()
b4.Caption = "But4"

# create a button that is situated at the left of region "Btn3".
# we need to offset it by -45 pixels so it doesn't overlap Btn3

y4 = FBAddRegionParam(0,FBAttachType.kFBAttachTop,"")

ShowTool(t)

大家执行一下试一试，decomposition and Restructure！
