 TGridPanelLayout

 GridPanelLayout1、GridPanelLayout

.Layouts.TGridPanelLayout

行高设为指定的值或按比例缩放。

九宫格

TGridPanelLayout.TCellItem.SizeStyle，​​Absolute，​​​​Percent​​

选中控件，ColumnCollection，RowCollection添加列行

GridPanel1.ControlCollection.BeginUpdate;
   while GridPanel1.ControlCollection.Count > 0 do
   GridPanel1.ControlCollection.Items[0].Control.DisposeOf;
1.
2.
3.

 

 TFlowLayout
控件大小可不相同。

TFlowPanel的效果图，里边是panel，左侧是TCategoryButtons，搜索框是TButtonedEdit

panel作为卡片。设置每个子panel属性即可。pnl.AlignWithMargins:=true，panel.Margins.Top:=20; 左右上下的边距设定就可以了。

 TGridLayou:表格，自动排列容器里的控件，控件大小相同可自定义大小，设定后全部控件大小相同且不变，x行y列，行数列列数根据控件大小变动。

TButtonGroup

TRectangle 好用，有填充颜色

 堆栈Panel，一行只有一个控件(不能多列），或一列只有一个控件（不能多行）

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:

RelativePanel
Seattle就有了
