[x] 总结Blender面板布局

总结

Blender面板中界面组件是通过UILayout进行组织的. 其主要属性如下:

row() 定义横向子布局.
column() 定义竖向子布局.
split() 按比例拆分行
column_flow() 定义多列的竖向子布局(根据列,计算行数, 然后按逐列摆放组件)
box() 定义有外框的竖向子布局
menu_pie() 饼状菜单
operator() 放置调用操作器的按钮
prop() 展示RNA,并把它放在布局中
label() 显示标签
separator() 分隔元素

代码示例

class SimplePanel(bpy.types.Panel):

    bl_space_type = 'VIEW_3D'

    bl_region_type = "TOOLS"

    bl_category = "Test"

    bl_label = "测试工具"

    bl_context = "objectmode"

    def draw(self, context):

        # Store reference to context.scene

        scn = context.scene

        # Store reference to self.layout

        lay = self.layout

        # Create box

        box = lay.column_flow(2)

        box.operator("object.simple_operator", text="Print #1")

        box.prop(scn, 'encouraging_message')

        box.operator("object.simple_operator", text="Print #1")

        box.prop(scn, 'encouraging_message')

        box.operator("object.simple_operator", text="Print #1")

        # Create another box

        box = lay.box()

        # Create a row within it

        row = box.row()

        # We can jam a few things on the same row

        row.operator("object.simple_operator", text="Print #2")

        row.prop(scn, 'encouraging_message')

        # Create yet another box

        box = lay.box()

        # Create a row just for a label

        row = box.row()

        row.label('There is a split row below me!')

        # Create a split row within it

        row = box.row()

        splitrow = row.split(percentage=0.2)

        # Store references to each column of the split row

        left_col = splitrow.column()

        right_col = splitrow.column()

        left_col.operator("object.simple_operator", text="Print #3")

        right_col.prop(scn, 'encouraging_message')

        # Throw a separator in for white space...

        lay.separator()

        # We can create columns within rows...

        row = lay.row()

        col = row.column()

        col.prop(scn, 'my_int_prop')

        col.prop(scn, 'my_int_prop')

        col.prop(scn, 'my_int_prop')

        col = row.column()

        col.prop(scn, 'my_float_prop')

        col.label("I'm in the middle of a column")

        col.prop(scn, 'my_float_prop')

        # Throw a few separators in...

        lay.separator()

        lay.separator()

        lay.separator()

        # Same as above but with boxes...

        row = lay.row()

        box = row.box()

        box.prop(scn, 'my_int_prop')

        box.label("I'm in the box, bottom left.")

        box = row.box()

        box.prop(scn, 'my_bool_prop')

        box.operator("object.simple_operator", text="Print #4")

    @classmethod

    def register(cls):

        print("Register class: %s" % cls.bl_label)

    @classmethod

    def unregister(cls):

        print('Unregister class: %s' % cls.bl_label)
