Quick Start

1. Install the NuGet package

Install-Package WinUI.Dock

2. Add the DockManager control in MainWindow.xaml

<Window xmlns:dock="using:WinUI.Dock"
        x:Name="Main">
    <dock:DockManager CreateNewDocument="OnCreateNewDocument"
                      CreateNewGroup="OnCreateNewGroup"
                      CreateNewWindow="OnCreateNewWindow"
                      ParentWindow="{Binding ElementName=Main}">
        <dock:LayoutPanel Orientation="Vertical">
            <dock:LayoutPanel DockHeight="2" Orientation="Horizontal">
                <dock:DocumentGroup DockWidth="2">
                    <dock:Document Title="Document" CanClose="False" CanPin="False" />
                </dock:DocumentGroup>

                <dock:DocumentGroup DockWidth="1">
                    <dock:Document Title="Solution Explorer" />
                </dock:DocumentGroup>
            </dock:LayoutPanel>

            <dock:LayoutPanel DockHeight="1" Orientation="Horizontal">
                <dock:DocumentGroup IsTabWidthBasedOnContent="True" TabPosition="Bottom">
                    <dock:Document Title="Side##Error List" />
                </dock:DocumentGroup>
                <dock:DocumentGroup IsTabWidthBasedOnContent="True" TabPosition="Bottom">
                    <dock:Document Title="Side##Output" />
                </dock:DocumentGroup>
            </dock:LayoutPanel>
        </dock:LayoutPanel>
    </dock:DockManager>
</Window>

3. Add the following code in MainWindow.xaml.cs

// This event is triggered when restoring the layout, you can add content to the Document in this event.
private void OnCreateNewDocument(object _, CreateNewDocumentEventArgs e)
{
    e.Document.Content = new TextBlock()
    {
        HorizontalAlignment = HorizontalAlignment.Center,
        VerticalAlignment = VerticalAlignment.Center,
        Text = $"New Document {e.Title}"
    };
}

// A special character "##" is added in the Title, and only the content after "##" will be displayed in the final interface.
// When dragging a Document to a specified target, a new DocumentGroup will be created, and this event will be triggered, allowing you to customize the properties of the DocumentGroup.
private void OnCreateNewGroup(object _, CreateNewGroupEventArgs e)
{
    if (e.Title.Contains("Side"))
    {
        e.Group.TabPosition = TabPosition.Bottom;
        e.Group.IsTabWidthBasedOnContent = true;
    }
}

// When dragging a Document out, a new window will be created, and this event will be triggered, allowing you to customize the title bar of the window.
private void OnCreateNewWindow(object _, CreateNewWindowEventArgs e)
{
    e.TitleBar.Child = new TextBlock()
    {
        HorizontalAlignment = HorizontalAlignment.Center,
        VerticalAlignment = VerticalAlignment.Center,
        Text = "Custom Title"
    };
}

4. Run the program to see the effect.

Notes

• The project is currently in an early stage and may have many issues. Please do not use it in production environments.
• The Uno Platform has only been tested on the Skia platform and does not support cross-window dragging. It works properly if used within a single window.
