Control.MouseClick 事件

定義

發生於使用滑鼠按一下控制項時。Occurs when the control is clicked by the mouse.

public:
 event System::Windows::Forms::MouseEventHandler ^ MouseClick;
public event System.Windows.Forms.MouseEventHandler MouseClick;
member this.MouseClick : System.Windows.Forms.MouseEventHandler 
Public Custom Event MouseClick As MouseEventHandler 

範例

下列程式碼範例示範如何使用這個成員。The following code example demonstrates the use of this member. 在此範例中,事件處理常式會報告 MouseClick 事件的發生次數。In the example, an event handler reports on the occurrence of the MouseClick event. 此報表可協助您瞭解事件發生的時間,並可協助您進行調試。This report helps you to learn when the event occurs and can assist you in debugging. 若要報告多個事件或經常發生的事件,請考慮以 Console.WriteLine 取代 MessageBox.Show,或將訊息附加到多行 TextBoxTo report on multiple events or on events that occur frequently, consider replacing MessageBox.Show with Console.WriteLine or appending the message to a multiline TextBox.

若要執行範例程式碼,請將它貼到專案中,其中包含繼承自 Control 的類型實例,例如 ButtonComboBoxTo run the example code, paste it into a project that contains an instance of a type that inherits from Control, such as a Button or ComboBox. 然後將實例命名為 Control1,並確定事件處理常式與 MouseClick 事件相關聯。Then name the instance Control1 and ensure that the event handler is associated with the MouseClick event.

private void Control1_MouseClick(Object sender, MouseEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "Button", e.Button );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Clicks", e.Clicks );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "X", e.X );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Y", e.Y );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Delta", e.Delta );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Location", e.Location );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "MouseClick Event" );
}
Private Sub Control1_MouseClick(sender as Object, e as MouseEventArgs) _ 
     Handles Control1.MouseClick

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "Button", e.Button)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Clicks", e.Clicks)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "X", e.X)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Y", e.Y)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Delta", e.Delta)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Location", e.Location)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"MouseClick Event")

End Sub

備註

當游標停留在控制項上時按下滑鼠按鍵,通常會從控制項引發下列一連串的事件:Depressing a mouse button when the cursor is over a control typically raises the following series of events from the control:

  1. MouseDown 事件。MouseDown event.

  2. Click 事件。Click event.

  3. MouseClick 事件。MouseClick event.

  4. MouseUp 事件。MouseUp event.

若要進行這項工作,則無法在控制項的類別中停用各種事件。For this to occur, the various events cannot be disabled in the control's class.

只要按下使用者作業系統的滑鼠設定所決定的兩次按鍵,就會產生 MouseDoubleClick 事件,而不是第二個 MouseClick 事件。Two single clicks that occur close enough in time, as determined by the mouse settings of the user's operating system, will generate a MouseDoubleClick event instead of the second MouseClick event.

重要

Click 事件在邏輯上是控制項的較高層級事件。Click events are logically higher-level events of a control. 這些通常是由其他動作引發,例如當控制項有焦點時按 ENTER 鍵。They are often raised by other actions, such as pressing the ENTER key when the control has focus.
