在 Windows 窗体上将按钮添加到窗口的一侧 [英] Adding Buttons To Side Of Window On Windows Form

问题描述

我想在 C# (在外面) 上向我的窗口窗体的一侧添加按钮.当窗口移动时，按钮应该一起移动.

I would like to add buttons to side of my windows form on C# (in outside). The buttons should move together as soon as when the window was moved.

例如:

推荐答案

我看到两个选项:

• 或者将按钮放在一个单独的表单中，并通过编写 Move 和 Resize 事件使两个表单粘在一起.

• Either put the buttons in a separate form and make both forms stick together by coding the Move and maybe Resize events.

或者，更简单的是，使表单 透明 并删除 Border 和 Title 区域.我会选择这个选项.

Or, simpler, make the Form transparent and remove Border and Title area. I would go for this option.

给你:

首先您通过以下方式设置表单样式:

First you style the Form by:

• 设置 this.ControlBox = false;
• 设置 this.MaximizeBox = false;
• 设置this.MinimizeBox = false;
• 设置this.Text="";
• 设置 this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;
• 设置this.BackColor = System.Drawing.Color.Fuchsia;
• 设置 this.TransparencyKey = this.BackColor;

现在添加到Form

• 一个Panel，它填充Form
的右侧、主要部分
• 你想要附加的Button
• 在主 Panel 中添加一个 Label (label1)，填充顶部并保持表单的标题文本
• 一个 Tab 控件等.

• a Panel that fills the right, main portion of the Form
• the Button you want attached
• a Label (label1) inside the main Panel, filling the top and holding the form's title text
• a Tab control etc..

最后我们要添加代码使表单可移动:

Finally we want to add code to make the form moveable:

using System.Runtime.InteropServices;
..

public const int WM_NCLBUTTONDOWN = 0xA1;
public const int HT_CAPTION = 0x2;

[DllImportAttribute("user32.dll")]
public static extern int SendMessage(IntPtr hWnd, int Msg, int wParam, int lParam);
[DllImportAttribute("user32.dll")]
public static extern bool ReleaseCapture();

private void label1_MouseDown(object sender, MouseEventArgs e)
{
    if (e.Button == MouseButtons.Left)
    {
        ReleaseCapture();
        SendMessage(Handle, WM_NCLBUTTONDOWN, HT_CAPTION, 0);
    }
}

您也可以查找代码以使窗口变大..

You can look up code to make the window sizeable, too..

您可以查找代码以使用区域为按钮提供非矩形形状.请注意，您需要在此处避免使用抗锯齿像素，否则紫红色会透过.

You can look up code to give the button a non-rectangular shape using a region. Note that you need to avoid anti-aliased pixels here or else the Fuchsia will shine through.
