页面设计需求,做了一个气泡形状的弹出框,效果如下:
设计思路如下:
1. 使用Path绘制气泡的尖尖,将这个放到顶层;
2. 在用border绘制长方形框,将这个放到底层,并且设置Margin值,使得Path图层和border看起来衔接在一起。
代码如下:

后台代码,很简单,就是控制pupup显示或隐藏
private void btnTestPopup1_Click(object sender, RoutedEventArgs e) { pop1.IsOpen = true; } private void btnOK1_Click(object sender, RoutedEventArgs e) { pop1.IsOpen = false; } private void btnCancel1_Click(object sender, RoutedEventArgs e) { pop1.IsOpen = false; } private void btnTestPopup2_Click(object sender, RoutedEventArgs e) { pop2.IsOpen = true; } private void btnOK2_Click(object sender, RoutedEventArgs e) { pop2.IsOpen = false; } private void btnCancel2_Click(object sender, RoutedEventArgs e) { pop2.IsOpen = false; } private void btnTestPopup3_Click(object sender, RoutedEventArgs e) { pop3.IsOpen = true; } private void btnOK3_Click(object sender, RoutedEventArgs e) { pop3.IsOpen = false; } private void btnCancel3_Click(object sender, RoutedEventArgs e) { pop3.IsOpen = false; } private void btnTestPopup4_Click(object sender, RoutedEventArgs e) { pop4.IsOpen = true; } private void btnOK4_Click(object sender, RoutedEventArgs e) { pop4.IsOpen = false; } private void btnCancel4_Click(object sender, RoutedEventArgs e) { pop4.IsOpen = false; }

RTX 5090要首发 性能要翻倍!三星展示GDDR7显存
三星在GTC上展示了专为下一代游戏GPU设计的GDDR7内存。
首次推出的GDDR7内存模块密度为16GB,每个模块容量为2GB。其速度预设为32 Gbps(PAM3),但也可以降至28 Gbps,以提高产量和初始阶段的整体性能和成本效益。
据三星表示,GDDR7内存的能效将提高20%,同时工作电压仅为1.1V,低于标准的1.2V。通过采用更新的封装材料和优化的电路设计,使得在高速运行时的发热量降低,GDDR7的热阻比GDDR6降低了70%。
