• 获取鼠标当前位置的相对坐标、模拟鼠标点击事件

    Dialogs;

    var
    Form1: TForm1;
    
    implementation
    
    {$R *.dfm}
    
    //方法一: 使用 OnMouseDown 事件的参数:
    procedure TForm1.FormMouseDown(Sender: TObject; Button: TMouseButton;
    Shift: TShiftState; X, Y: Integer);
    begin
    //参数中的 X,Y 就是当前鼠标所在位置的坐标
    //譬如显示看看:
    Text := Format('OnMouseDown: x=%d; y=%d', [X,Y]);
    end;
    
    //方法二: 使用 OnMouseMove 事件的参数:
    procedure TForm1.FormMouseMove(Sender: TObject; Shift: TShiftState; X,
    Y: Integer);
    begin
    //参数中的 X,Y 就是当前鼠标所在位置的坐标
    //譬如显示看看:
    Text := Format('OnMouseMove: x=%d; y=%d', [X,Y]);
    end;
    
    //方法三: 使用 OnMouseUp 事件的参数:
    procedure TForm1.FormMouseUp(Sender: TObject; Button: TMouseButton;
    Shift: TShiftState; X, Y: Integer);
    begin
    //参数中的 X,Y 就是当前鼠标所在位置的坐标
    //譬如显示看看:
    ShowMessage(Format('OnMouseUp: x=%d; y=%d', [X,Y]));
    end;
    
    //方法四: 使用 API 函数 GetCursorPos:
    procedure TForm1.FormClick(Sender: TObject);
    var
    pt: TPoint;
    begin
    GetCursorPos(pt); {这是获取的相对于屏幕的坐标}
    pt := ScreenToClient(pt); {转换成本地坐标}
    ShowMessage(Format('API 函数 GetCursorPos: x=%d; y=%d', [pt.X, pt.Y]));
    end;
    
    end.
