删除边框winforms和WindowState最大化没有全屏

Question

我遇到以下问题，但我找不到解决方案。

我想实现一个没有顶栏的Winform，如果可能的话，没有边框。我尝试了几件没有成功的事情，以下方法可以完美地完成这个工作：

        this.Text = string.Empty;
        this.ControlBox = false;
        this.FormBorderStyle = FormBorderStyle.SizableToolWindow;

产生以下结果：

小问题是当我或用户触发最大化状态时，因为会使表单进入FULLSCREEN模式！我不知道如何防止这种情况：

请参阅？你看不到windows任务栏！我正在使用

WindowState = FormWindowState.Maximized; // Makes a fullscreen that i dont want !

感谢您的帮助！

Answer 1

尝试动态设置大小，它可能对您有帮助。

不要使用WindowState = FormWindowState.Maximized; 在加载表单时尝试此代码

var rectangle = ScreenRectangle();
Size = new Size(rectangle.Width - 100, rectangle.Height - 100);
Location = new Point(50, 50);
// here 100 is pixel used to reserve from edges, 
// you can set lower value according to your requirements

完整尺寸

var rectangle = ScreenRectangle();
Size = new Size(rectangle.Width, rectangle.Height);
Location = new Point(0, 0);

屏幕矩形方法是：

public Rectangle ScreenRectangle()
{
    return Screen.FromControl(this).Bounds;
}

好吧！感谢您的所有答案，我终于用以下两种方法解决了

    private void MaximizeWindow() 
    {
        var rectangle = Screen.FromControl(this).Bounds;
        this.FormBorderStyle = FormBorderStyle.None;
        Size = new Size(rectangle.Width, rectangle.Height);
        Location = new Point(0, 0);
        Rectangle workingRectangle = Screen.PrimaryScreen.WorkingArea;
        this.Size = new Size(workingRectangle.Width, workingRectangle.Height);
    }

    private void ResizableWindow() 
    {
        this.ControlBox = false;
        this.FormBorderStyle = FormBorderStyle.SizableToolWindow;
    }

感谢X-TECH和Luïs，这已经解决了！

如果您希望控制而不是表单最大化，请执行以下操作：

  public class MyForm {
    protected override void WndProc(ref Message m) {
      const int WM_SYSCOMMAND = 0x0112;
      const int SC_MAXIMIZE = 0xF030;

      // When form is going to be maximized    
      if ((m.Msg == WM_SYSCOMMAND) && (m.WParam.ToInt32() == SC_MAXIMIZE)) {
        m.Msg = 0; // <- we don't want a standard maximization
        //TODO: tell Windows here what to do when user want to maximize the form

        // Just a sample (pseudo maximization)
        Location = new Point(0, 0);
        Size = new Size(Screen.GetWorkingArea(this).Width,
                        Screen.GetWorkingArea(this).Height);
      }

      base.WndProc(ref m);
    } 
    ...
  }

Answer 4

删除边框

this.FormBorderStyle = FormBorderStyle.None;

我认为单击最大化按钮

可以解决这个问题

// Add following namespaces
using System.Windows.Forms;
using System.Drawing;

// Retrieve the working rectangle from the Screen class using the PrimaryScreen and the 
// WorkingArea properties.
Rectangle workingRectangle = Screen.PrimaryScreen.WorkingArea;

// Set the size of the form slightly less than size of working rectangle. 
this.Size = new Size(workingRectangle.Width, workingRectangle.Height);

嗨，你只能用2条指令来做到这一点：        this.MaximumSize = Screen.PrimaryScreen.WorkingArea.Size;             this.WindowState = FormWindowState.Maximized;

Answer 6

group_concat

GetWorkingArea ：获取显示的工作区域。工作区域是显示器的桌面区域，不包括任务栏，停靠窗口和停靠工具栏。MSDN
