TGroupBox中的透明背景色-DELPHI [英] Transparent background color in TGroupBox - DELPHI

问题描述

如何在TGroupBox中设置透明背景颜色？

How can i set transparent background color in TGroupBox?

以Delphi的形式，我有一个GroupBox和一个Panel（图形覆盖）。

我编写了一个使用Rect在面板上绘制渐变填充的过程。

现在，我还有另一个问题：GroupBox背景色来自Form，但我希望它与Panel相同。我不能将GroupBox放到Panel中，因为绘制过程会填满整个Panel区域（也是GroupBox）。
有没有一种方法（通过代码）来设置GroupBox的透明背景颜色？

In my Delphi's form I have a GroupBox and a Panel (graphically overlaid).
I wrote a procedure to draw a gradient fill on the Panel using Rect. It works!
Now I have another problem: GroupBox backgound color descends from the Form but I wish it was the same of Panel. I can't put GroupBox into Panel because draw procedure fill the entire Panel area (also GroupBox).
Is there a way (by code) to set trasparent background color of GroupBox?

推荐答案

我在运行时解决了设置GroupBox的Parent属性的问题。

I solved setting at runtime the Parent property of the GroupBox.
