Simple code description
请随手创建一个 WPF 项目（.NET Framework、.NET 5\6\7 皆可），使用tree /f命令看看最终的文件结构，和上面的截图一致：
C:.
│ ModernLoginPage.xaml
│ ModernLoginPage.xaml.cs
│
└─Images
close.png
email.png
github.png
google.png
lock.png
wechat.png
简单吧，一个图片目录存放前面下载的图标，一个xaml文件做登录界面设计，xaml.cs做界面按钮响应事件处理（实际项目建议使用 Mvvm)。
Look at the screenshot above and focus on these two points:
- Graphical controls on the left
公司有设计师，做这种图片是很简单的，没有的时候，可以使用Polygon、Ellipse等实现一些简单的效果，让界面不要那么单调：
<Canvas>
<Polygon Points="0, 20 230,140 0,270" Fill="#4EB1B6" />
<Polygon Points="100, 400 200,370 180,470" Fill="#4EB1B6" />
<Ellipse Margin="250 450 0 0" Width="40" Height="40" Fill="#4EB1B6" />
<Ellipse Margin="50 400 0 0" Width="20" Height="20" Fill="#4EB1B6" />
</Canvas>
- The account text box and password box on the right
作者为了演示效果，账号文本框使用的 一张图片 + 一个标签控件 + 一个文本框 控件组合实现：
<Border Padding="10" BorderThickness="1" BorderBrush="#acb0af" Margin="70 7" CornerRadius="5">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Image Source="/TerminalMACS.TestDemo;component/Views/ModernLogin/Images/email.png" Height="20" />
<TextBlock x:Name="textEmail" MouseDown="textEmail_MouseDown" Text="邮箱"
Style="{StaticResource textHint}" />
<TextBox x:Name="txtEmail" TextChanged="txtEmail_TextChanged" Style="{StaticResource textBox}" />
</Grid>
</Border>
private void textEmail_MouseDown(object sender, MouseButtonEventArgs e)
{
txtEmail.Focus();
}
private void txtEmail_TextChanged(object sender, TextChangedEventArgs e)
{
if (!string.IsNullOrEmpty(txtEmail.Text) && txtEmail.Text.Length > 0)
{
textEmail.Visibility = Visibility.Collapsed;
}
else
{
textEmail.Visibility = Visibility.Visible;
}
}
The code is relatively simple, the.cs file code:
- When the mouse clicks on a tab, set the account text box as a focus control to improve the user experience
- Display when entering account information in the text box| hidden tag
The password box logic is the same as the account text box:
<Border Padding="10" BorderThickness="1" BorderBrush="#acb0af" Margin="70 7" CornerRadius="5">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="auto" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Image Source="/TerminalMACS.TestDemo;component/Views/ModernLogin/Images/lock.png" Height="20" />
<TextBlock x:Name="textPassword" MouseDown="textPassword_MouseDown" Text="密码"
Style="{StaticResource textHint}" />
<PasswordBox x:Name="txtPassword" PasswordChanged="txtPassword_TextChanged"
Style="{StaticResource textBox}" />
</Grid>
</Border>
private void textPassword_MouseDown(object sender, MouseButtonEventArgs e)
{
txtPassword.Focus();
}
private void txtPassword_TextChanged(object sender, RoutedEventArgs e)
{
if (!string.IsNullOrEmpty(txtPassword.Password) && txtPassword.Password.Length > 0)
{
textPassword.Visibility = Visibility.Collapsed;
}
else
{
textPassword.Visibility = Visibility.Visible;
}
}
