[英]How do I make a WinUI 3 GUI in code without XAML?
I'm porting a programming language to Windows that has commands like "create a window" and "create a pushbutton in that window".我正在将一种编程语言移植到 Windows,它具有“创建窗口”和“在该窗口中创建按钮”等命令。 The programming language itself is implemented in C++.
编程语言本身在 C++ 中实现。
I hear the newest, recommended UI API on Windows going forward is WinUI 3, but I couldn't really find any good information on how to define a GUI in code instead of loading it from XAML files.我听说 Windows 上最新的推荐 UI API 是 WinUI 3,但我真的找不到任何关于如何在代码中定义 GUI 而不是从 Z8CBFD56579569C46DDED1B21D83F1BDZ3 文件加载它的好信息。

This example is in C#, but it should also work in C++.这个例子在 C# 中,但它也应该在 C++ 中工作。
Perform the folling steps:执行以下步骤:
OnLaunched
method. OnLaunched
方法的代码。 See the example belowThe example code creates an instance of type Window with a StackPanel
as content.示例代码创建了一个类型为Window的实例,其中
StackPanel
作为内容。 The StackPanel
contains a TextBlock
and a Button
. StackPanel
包含一个TextBlock
和一个Button
。 If you click on the Button, the event handling code will write someting using Debug.WriteLine
.如果单击按钮,事件处理代码将使用
Debug.WriteLine
编写一些东西。
/// <summary>
/// Invoked when the application is launched normally by the end user. Other entry points
/// will be used such as when the application is launched to open a specific file.
/// </summary>
/// <param name="args">Details about the launch request and process.</param>
protected override void OnLaunched(Microsoft.UI.Xaml.LaunchActivatedEventArgs args)
{
// The original version of the method just contained these two lines:
//m_window = new MainWindow();
//m_window.Activate();
m_window = new Window();
StackPanel stackPanel = new StackPanel();
TextBlock textBlock = new TextBlock();
textBlock.Text = "Text of the TextBlock";
Button button = new Button();
button.Content = "Click Me";
button.Click += (object sender, RoutedEventArgs e) => { Debug.WriteLine("Button clicked"); };
stackPanel.Children.Add(textBlock);
stackPanel.Children.Add(button);
m_window.Content = stackPanel;
m_window.Activate();
}
