继承父母的背景色prevent按钮 [英] Prevent Button from inheriting BackColor of Parent

问题描述

当我有一个家长控制，有一个背景色比 SystemColors.Control 等，但我有按钮在系统中他们得出我想要的家长控制。然而，当我不改变背景色的按钮，它绘制在母的颜色。当我在背景色按钮更改为 SystemColors.Control ，它不是在Windows主题绘制了。

左版本与 SystemColors.Control 键，右边则是在不改变背景色。的

炸掉了，它看起来像这样。在这里，您可以看到按钮有一个坚实的背景。的

任何建议，我怎么能解决这个问题？

图片中的效果可以通过创建一个新的.NET 2.0的WinForms项目和不断变化的 Form1中的构造函数如下完成的：

 公共Form1中（）
{
    的InitializeComponent（）;

    VAR的textBox =新文本框（）;
    Controls.Add被（的textBox）;

    VAR按钮=新按钮的{text =L，宽度= 23，身高= 18，左= -1，顶= -1};
    textBox.Controls.Add（按钮）;

    //禁止线下获取默认行为
    button.BackColor = SystemColors.Control;
}
 

解决方案

我unforuantely只能访问到Windows 7的时刻，所以我不能在XP等测试，但你叫应用程序。 EnableVisualStyles 在主进入你的WinForms应用程序的呢？

在Windows 7的Aero启用按钮不承担父颜色，如果 Application.EnableVisualStyles 之称。

注：您应该设置 button.UseVisualStyleBackColor = TRUE; 并没有明确地设置背景色按钮的属性。

When I have a parent control which has a BackColor other than SystemColors.Control, but I have buttons on that parent control that I want to be drawn in the system them. However, when I do not change the BackColor of the buttons, it's drawn in the color of the parent. When I change the BackColor of the button to SystemColors.Control, it isn't drawn in the Windows theme anymore.

The left version is with SystemColors.Control and the right is without changing the BackColor.

Blown up, it looks like this. Here you can see that the buttons have a solid background.

Any suggestions how I can fix this?

The effect in the image can be accomplished by creating a new .NET 2.0 WinForms project and changing the constructor of Form1 to the following:

public Form1()
{
    InitializeComponent();

    var textBox = new TextBox();
    Controls.Add(textBox);

    var button = new Button { Text = "L", Width = 23, Height = 18, Left = -1, Top = -1 };
    textBox.Controls.Add(button);

    // Disable the line below to get the default behavior
    button.BackColor = SystemColors.Control;
}

解决方案

I unforuantely only have access to Windows 7 at the moment so I can't test on XP etc. but are you calling Application.EnableVisualStyles in the Main entry point of your WinForms application?

On Windows 7 with Aero enabled the buttons do not assume the parent color if Application.EnableVisualStyles is called.

NB: You should set button.UseVisualStyleBackColor = true; and do not explicitly set the BackColor property of the button.
