关于font.go

[52LY]

你好，我看了tk/font.go,

func NewUserFont(family string, size int, attributes ...*FontAttr) *UserFont
func NewUserFontFromClone(font Font) *UserFont

这两个函数返回*UserFont，我大概明白

下面几个设置*UserFont属性的函数：

func (w *UserFont) SetFamily(family string) *UserFont 
func (w *UserFont) SetSize(size int) *UserFont
func (w *UserFont) SetBold(bold bool) *UserFont 
func (w *UserFont) SetItalic(italic bool) *UserFont 
func (w *UserFont) SetUnderline(underline bool) *UserFont
func (w *UserFont) SetOverstrike(overstrike bool) *UserFont 

都返回了*UserFont，设置字体属性完毕后我感觉应该不需要返回*UserFont 如有错误，请见谅

我看了下font的demo，这里面： https://github.com/visualfc/atk_demo/blob/master/font/font.go, 第三十八行

是这样写的，w.font.SetFamily(cmbFamily.CurrentText()) 而不是 w.font = w.font.SetFamily(cmbFamily.CurrentText())

https://github.com/visualfc/atk/blob/master/tk/layout.go， 51行至81行的几个Set函数也是这样

func (w *LayoutSpacer) SetSpace(space int) *LayoutSpacer
func (w *LayoutSpacer) SetExpand(expand bool) *LayoutSpacer
func (w *LayoutSpacer) SetWidth(width int) *LayoutSpacer
func (w *LayoutSpacer) SetHeight(height int) *LayoutSpacer

谢谢指正，这块返回 error 比较适合。
