TFlowPanel的效果圖，里邊是panel，左側是TCategoryButtons，搜索框是TButtonedEdit

panel作為卡片。設置每個子panel屬性即可。pnl.AlignWithMargins:=true，panel.Margins.Top:=20; 左右上下的邊距設定就可以了。

?TGridLayou:表格，自動排列容器里的控件，控件大小相同可自定義大小，設定后全部控件大小相同且不變，x行y列，行數列列數根據控件大小變動。

The stack panel is a panel with a special layout. All controls added to it are placed in a different "row" (or column if you set it horizontally). The controls can be aligned to the left, the right,?the center or use the entire space (fill). You set the default alignment at the stack panel level, and you can override it for each individual control (or use the special default value to pick the parent control setting). Each of the controls hosted by the panel, gets three additional properties "injected" by the container -- at the bottom of the Object Inspector list -- as you can see below:
