幾何管理方法place中anchor的含義

關(guān)于place的用法，重點在于理解anchor的用法。

在一個大矩形中準(zhǔn)確地定義一個小矩形（有面積，不是點）的位置，需要知道三個信息：一是坐標(biāo)系定義，二是坐標(biāo)數(shù)據(jù)，三是要在小矩形上指定一個定位點。原點和坐標(biāo)系完全是系統(tǒng)默認的定義方式，即原點在master控件的左上角，向右向下為正。

坐標(biāo)數(shù)據(jù)以相對形式給出，取0到1之間的浮點數(shù)。如果取0，則參考點橫坐標(biāo)為0（在最左側(cè)），如果取1，則參考點橫坐標(biāo)為master控件的最右側(cè)，縱坐標(biāo)也是如此。

定位點anchor的定義，這個是最終定位的關(guān)鍵。如圖：
