Boolean

如果部分壓下切換式工具列按鈕，則為 true，否則為 false。預設為 false。

範例

下列程式碼範例示範如何使用 Pushed 、和 PartialPush 屬性。若要執行此範例，請將下列程式碼貼到包含 RichTextBox 名為的 RichTextBox1 控制項的表單中。 InitializeToolBar 在表單的建構函式或 Load 方法中呼叫方法。

備註

當設定為 true 時 PartialPush ，工具列按鈕看起來會呈現灰色。當屬性設定 false 為時， Enabled 這個外觀與暗灰色外觀不同，因為部分推播外觀會讓整個按鈕臉部變得模糊。除非設定為 ToggleButton ， ToolBarButtonStyle 否則這個屬性沒有作用。
