2、说明

TAlphaColor = type Cardinal;  //整数.    AA RR GG BB(透明度、红、绿、蓝);

 

3、赋值方法

?

1 2 3 4 5

Text1.TextColor::= #FF7E7E7E; Text1.TextColor:= claGray;  // 需要引用 System.UIConsts Text1.TextColor:=TAlphaColors.Gray;     // Text1.TextColor:=TAlphaColorRec.Gray;   // Text1.TextColor := MakeColor(0, 0, 255); // 需要引用 System.UIConsts

 

其他用法示例，有时间再补充
