C# 如何在ToolStrip上渲染图形
我已经创建了一个自定义用户控件,它将显示文本和一个指示灯,以显示我们服务的当前运行状态,如下表所示。它在窗体上工作得很好,但我想将它放在StatusStrip控件上。我创建了一个派生自ToolStripControlHost的类,以支持StatusStrip上的控件,但它根本不呈现。控件的宽度为零,窗体在IDE中打开时闪烁 我已经看过ToolStripRendering类,但在我看来,它是用于现有支持的控件的 实现这一目标的最佳方式是什么?如果可能的话?我的代码如下 我正在使用Visual Studio 2010和.NET 4.0 用户控制代码:C# 如何在ToolStrip上渲染图形,c#,toolstrip,toolstripcontrolhost,C#,Toolstrip,Toolstripcontrolhost,我已经创建了一个自定义用户控件,它将显示文本和一个指示灯,以显示我们服务的当前运行状态,如下表所示。它在窗体上工作得很好,但我想将它放在StatusStrip控件上。我创建了一个派生自ToolStripControlHost的类,以支持StatusStrip上的控件,但它根本不呈现。控件的宽度为零,窗体在IDE中打开时闪烁 我已经看过ToolStripRendering类,但在我看来,它是用于现有支持的控件的 实现这一目标的最佳方式是什么?如果可能的话?我的代码如下 我正在使用Visual St
