MenuItem的颜色更改 [英] Color change for MenuItem
问题描述
我正在编写备份工具.在我的工具之上，我有一个菜单条，其中包含两个工具条菜单.我改变了颜色，使颜色达到了我的期望.不集中菜单看起来很棒:
I am programming a Backup Tool. On top of my tool I have a menustrip containing two toolstripmenuitems. I changed the colors a little bit to my expectations. Not focused the menu looks great:
当我现在单击菜单项文件"以打开上下文菜单时，颜色变为白色，并且我不再能够阅读文本:
When I now click on the menu item "File" to open the context menu, the color changes to white and I am not able to read the text anymore:
谁能告诉我在哪里可以改变这种行为?我使用Visual Studio 2013 Ultimate，Windows窗体应用程序，代码在C#中.
Can anyone please tell me where I can change that behavior? I use Visual Studio 2013 Ultimate, Windows Forms Application, Code is in C#.
这是代码:
//
// initializing menuStrip1
//
this.menuStrip1.BackColor = System.Drawing.Color.MediumBlue;
this.menuStrip1.BackgroundImageLayout =
System.Windows.Forms.ImageLayout.Center;
this.menuStrip1.Font = new System.Drawing.Font("Segoe UI Semilight",
15.75F, System.Drawing.FontStyle.Regular,//
System.Drawing.GraphicsUnit.Point, ((byte)(0)));
this.menuStrip1.Items.AddRange(new System.Windows.Forms.ToolStripItem[] {
this.fileToolStripMenuItem,
this.helpToolStripMenuItem});
this.menuStrip1.Location = new System.Drawing.Point(0, 0);
this.menuStrip1.MinimumSize = new System.Drawing.Size(0, 40);
this.menuStrip1.Name = "menuStrip1";
this.menuStrip1.Size = new System.Drawing.Size(1056, 40);
this.menuStrip1.TabIndex = 77;
this.menuStrip1.Text = "menuStrip1";
//

//
this.fileToolStripMenuItem.DropDownItems.AddRange(new

推荐答案
默认情况下，此功能开箱即用.您需要为工具栏创建一个自定义Renderer来实现此目的.
By default this feature is not available out of the box. You need to create a custom Renderer for you tool strip to achieve this.
创建一个从ToolStripProfessionalRenderer-
private class BlueRenderer : ToolStripProfessionalRenderer
{
protected override void OnRenderMenuItemBackground(ToolStripItemRenderEventArgs e)
{
Rectangle rc = new Rectangle(Point.Empty, e.Item.Size);
Color c = Color.MediumBlue;
using (SolidBrush brush = new SolidBrush(c))
e.Graphics.FillRectangle(brush, rc);
}
}
并将此渲染器附加到表单构造器中的菜单栏上-
And attach this renderer to your menu strip in your form constructor -
public Form1()
{
InitializeComponent();
menuStrip1.Renderer = new BlueRenderer();
}
