如何从最大化FormBorderStyle.FixedToolWindow的窗口中停止双击窗口标题栏？

Question

我很生气,我答应了一个用户无法调整大小的固定窗口,但当然他们可以双击标题栏以最大化这个"不可调整的"窗口.我该怎么办呢？我可以使用winforms代码执行此操作,还是必须转到Win32？

谢谢!

Answer 1

您可以将MaximizeBox表单的属性设置为false

Answer 2

您可以禁用标题栏上的双击消息(或更改最大化窗口的默认行为).它适用于任何FormBorderStyle:

private const int WM_NCLBUTTONDBLCLK = 0x00A3; //double click on a title bar a.k.a. non-client area of the form

        protected override void WndProc(ref Message m)
        {
            if (m.Msg == WM_NCLBUTTONDBLCLK)
            {
                m.Result = IntPtr.Zero;
                return;
            }
            base.WndProc(ref m);
        }

/// ///这是我们重写基本WIN32窗口过程,以防止鼠标移动窗体以及鼠标双击调整大小./// ///

    protected override void WndProc(ref Message m)
    {
        const int WM_SYSCOMMAND = 0x0112;
        const int SC_MOVE = 0xF010;
        const int WM_NCLBUTTONDBLCLK = 0x00A3; //double click on a title bar a.k.a. non-client area of the form

        switch (m.Msg)
        {
            case WM_SYSCOMMAND:             //preventing the form from being moved by the mouse.
                int command = m.WParam.ToInt32() & 0xfff0;
                if (command == SC_MOVE)
                    return;
                break;
        }

       if(m.Msg== WM_NCLBUTTONDBLCLK)       //preventing the form being resized by the mouse double click on the title bar.
        {
            m.Result = IntPtr.Zero;                   
            return;                   
        }

        base.WndProc(ref m);
    }
