示例
下面的代码示例演示如何使用 Pushed 、和 PartialPush 属性。The following code example demonstrates how to use the Pushed, and PartialPush properties. 若要运行该示例,请将以下代码粘贴到包含名为的控件的窗体中 RichTextBox RichTextBox1
。 InitializeToolBar
在窗体的构造函数或方法中调用方法 Load
。To run the example, paste the following code in a form containing a RichTextBox control called RichTextBox1
.Call the InitializeToolBar
method in the form's constructor or Load
method.

注解
当 PartialPush 设置为时 true
,工具栏按钮将显示为灰色。When PartialPush is set to true
, the toolbar button appears to have its face grayed. 当属性设置为时,此外观不同于灰显外观, Enabled false
因为部分推送外观为整个按钮表面提供了推移。This appearance is different from the dimmed appearance when the Enabled property is set to false
since the partial-push appearance gives a haze to the entire button face. 除非将设置为,否则此属性不起作用 ToolBarButtonStyle ToggleButton
。This property has no effect unless the ToolBarButtonStyle is set to ToggleButton
.
