-# Layout Specifications
-
-## overview
-This document is the specification of layout system.
-
-The layout system imitates WPF and Android layout system.
-
-## rules
-
-### about `width` and `height` in `LayoutParams`
-There is three mode in measure: `Content`, `Exactly`, `Stretch`.
-
-- `Exactly` means the control should be of an exact size.
-
-- `Content` means the control has the size that contains the children.
-
-- `Stretch` means the control stretch to the max size that it can fill. If parent is `Content`, it occupies all available room parent provides, which means its parent will stretch as well.
-
-### about `max_size`, `min_size`
-
-`max_size` specifies the max size and `min_size` specifies the min size. They are of higher priority of `width` and `height`. Calculated size should be adjusted according to the four properties.
-
-## structure
-
-### enum `MeasureMode`
-``` c++
-enum class MeasureMode
-{
-    Content,
-    Stretch,
-    Exactly
-};
-```
-
-### struct `MeasureLength`
-``` c++
-struct MeaureLength
-{
-    float length;
-    MeasureMode mode;
-};
-```
-
-### struct `MeaureSize`
-``` c++
-struct MeasureSize
-{
-    MeasureLength width;
-    MeasureLength height;
-};
-```
-
-### struct `OptionalSize`
-``` c++
-struct OptionalSize
-{
-    optional<float> width;
-    optional<float> height;
-}
-```
-
-### struct `BasicLayoutParams`
-``` c++
-struct BasicLayoutParams
-{
-    MeasureSize size;
-    OptionalSize max_size;
-    OptionalSize min_size;
-}
-```
-
-### interface `ILayoutable`
-``` c++
-struct ILayoutable : virtual Interface
-{
-    virtual void Measure(const Size&) = 0;
-    virtual void Layout(const Rect&) = 0;
-
-    virtual BasicLayoutParams* GetLayoutParams() = 0;
-    virtual void SetLayoutParams(BasicLayoutParams* params) = 0;
-
-    virtual Size GetDesiredSize() = 0;
-    virtual void SetDesiredSize(const Size& size) = 0;
-
-/*
-protected:
-    virtual Size OnMeasure(const Size& size);
-    virtual void OnLayout(const Rect& rect);
-*/
-};
-```
