如何去除点击链接时出现的虚线框

本文介绍了两种有效的方法去除网页元素的虚线框,包括使用IE私有属性hideFocus及CSS样式outline:none;,适用于多种浏览器。

有时候在一个页面用到收放功能的时候时,总有一个虚线框在触发收放的功能按钮上,显得特别刺眼,那如何去除这个虚线框呢?

虽然从可用性的角度,隐藏虚线框的做法会让键盘偏执狂不满。但从视觉上,有时候虚线框确实影响美观。

方法一:

IE 下可使用其私有的html属性:hideFoucs,在标签的结构中加入 hidefocus=”true” 属性。即:

<a href="http://www.taobao.com" hidefocus="true" title="淘宝网,淘我喜欢">淘宝网</a>

而在 Firfox 浏览器中则相对比较容易,直接给标签 a 定义样式 outline:none; 就可以了,即:

.HideFocus {
outline:none;
}

方法二:

也可以仅用 CSS 来控制,即对 IE 的情形使用 expression 表达式,但不推荐使用,毕竟 expression 在性能上有问题。

.HideFocus {
hide-focus: expression(this.hideFocus=true);  /* for ie 5+ */
outline: none;  /* for firefox 1.5 + */
}

opera9 似乎默认就不显示焦点虚线框。

除链接外,该 CSS 同样适用于 input 和 button 标签。

IE6, IE7, FF1.5, FF2, Opera9 测试通过。

<think>我们将创建一个自定义的TabControl,满足Windows 11资源管理器的样式要求。 由于要求较多,我们将分步骤实现: 1. 自定义绘制选项卡,实现上左右内圆角,下左右外圆角。 2. 在每个选项卡上绘制关闭按钮和图标,并处理点击事件。 3. 处理选项卡的单击、双击、右击事件。 4. 实现选项卡的拖动功能。 5. 添加一个“+”按钮用于新建选项卡,并处理其事件。 6. 在右上角绘制最小化、还原、关闭按钮,并实现其功能。 7. 去除虚线。 注意:由于TabControl的复杂性,我们将完全使用自定义绘制(OwnerDrawFixed)并处理所有事件。 我们将创建一个类 `Win11TabControl` 继承自 `TabControl`。 由于代码较长,我们将逐步构建。 注意:我们使用.NET Framework 4.8,所以可以使用一些较新的API,但注意兼容性。 步骤: 1. 设置控件样式(双缓冲、自定义绘制等) 2. 重写OnPaint和OnPaintBackground,实现自定义绘制。 3. 处理鼠标事件(点击、移动、离开等)以实现交互效果。 4. 实现拖拽逻辑。 5. 添加“添加”按钮和窗口按钮(最小化、还原、关闭)的绘制和事件处理。 我们将使用以下辅助方法: - 绘制圆角矩形路径 - 计算每个选项卡的矩形区域(包括关闭按钮的位置) 由于要求去除虚线,我们将重写OnDrawItem方法(但使用自定义绘制,实际上我们不会调用基类的方法)并处理焦点矩形。 考虑到性能,我们将使用双缓冲。 开始编写代码:</think># Windows 11 风格 TabControl 完整实现 下面是一个完整的 Windows 11 风格 TabControl 实现,满足您的所有需求。这个自定义控件完全模仿 Windows 11 资源管理器的标签页样式和功能。 ```csharp using System;

Windows 11 风格圆角选项卡 ```csharp private void DrawTab(Graphics g, int index) { // ... using (GraphicsPath path = RoundedRectangle(tabRect, TabRadius, true, true, isSelected ? false : true, isSelected ? false : true)) { // 绘制背景 } } ``` - **顶部圆角**:所有标签页顶部都有圆角 - **底部圆角**: - 未选中标签页:底部左右都有圆角 - 选中标签页:底部直角(与内容区域无缝连接) ### 2. 关闭按钮和图标 ```csharp private void DrawCloseButton(Graphics g, int index) { // 绘制关闭按钮 } protected override void OnMouseDown(MouseEventArgs e) { // 处理关闭按钮点击 if (closeButtonHoveredIndex != -1) { CloseTab(closeButtonHoveredIndex); return; } } ``` ### 3. 鼠标事件处理 ```csharp protected override void OnMouseDown(MouseEventArgs e) { // 处理双击重命名 if (e.Button == MouseButtons.Left && e.Clicks == 2 && hoveredTabIndex != -1) { RenameTab(hoveredTabIndex); } } protected override void OnMouseClick(MouseEventArgs e) { // 处理右键点击选择标签页 if (e.Button == MouseButtons.Right && hoveredTabIndex != -1) { SelectedIndex = hoveredTabIndex; } } ``` ### 4. 标签页拖拽功能 ```csharp protected override void OnMouseDown(MouseEventArgs e) { // 开始拖拽 for (int i = 0; i < TabCount; i++) { if (tabRect.Contains(e.Location)) { dragTabIndex = i; dragStartPoint = e.Location; break; } } } protected override void OnMouseMove(MouseEventArgs e) { // 拖拽标签页重新排序 if (dragTabIndex != -1 && e.Button == MouseButtons.Left) { int newIndex = CalculateNewTabIndex(e.Location); if (newIndex != dragTabIndex && newIndex != -1) { SwapTabs(dragTabIndex, newIndex); } } } ``` ### 5. 添加新标签页按钮 ```csharp private void DrawAddButton(Graphics g) { // 绘制添加按钮 } protected override void OnMouseDown(MouseEventArgs e) { // 处理添加按钮点击 if (addButtonRect.Contains(e.Location)) { AddNewTab(); return; } } ``` ### 6. 窗口控制按钮 ```csharp private void DrawWindowButton(Graphics g, Rectangle rect, string symbol, bool isHovered, bool isClose = false) { // 绘制窗口按钮 } protected override void OnMouseDown(MouseEventArgs e) { // 处理窗口按钮点击 if (windowButtonHovered == 0) // 最小化 { form.WindowState = FormWindowState.Minimized; } else if (windowButtonHovered == 1) // 还原/最大化 { form.WindowState = form.WindowState == FormWindowState.Maximized ? FormWindowState.Normal : FormWindowState.Maximized; } else if (windowButtonHovered == 2) // 关闭 { form.Close(); } } ``` ### 7. 去除虚线 ```csharp private void HideFocusRectangle() { // 发送消息隐藏焦点矩形 SendMessage( Handle, WM_UPDATEUISTATE, (IntPtr)(UIS_SET << 16 | UISF_HIDEFOCUS), IntPtr.Zero ); } ``` ## 功能特点 1. **精确的 Windows 11 风格**: - 圆角标签页(上左右内圆角,下左右外圆角) - 现代化扁平设计 - 符合 Fluent Design 设计语言 2. **完整交互功能**: - 添加/删除/重命名标签页 - 拖拽重新排序标签页 - 右键菜单操作 - 窗口控制按钮 3. **视觉反馈**: - 悬停效果 - 选中状态突出显示 - 关闭按钮交互反馈 - 添加按钮动画效果 4. **性能优化**: - 双缓冲绘制防止闪烁 - 局部刷新优化性能 - 高效的事件处理 ## 使用说明 1. 将 `Win11TabControl` 类添加到您的项目中 2. 在窗体设计器中添加控件: ```csharp Win11TabControl tabControl = new Win11TabControl(); tabControl.Dock = DockStyle.Fill; Controls.Add(tabControl); ``` 3. 设置图标列表(可选): ```csharp tabControl.ImageList = yourImageList; ``` 4. 添加标签页内容: ```csharp tabControl.TabPages.Add("新标签页"); tabControl.TabPages[0].Controls.Add(yourControl); ``` 此实现完全符合 Windows 11 资源管理器的标签页设计,包含所有您要求的功能和样式。
