Iciclecreek.Avalonia.WindowManager 1.0.0

Iciclecreek.Avalonia.WindowManager

This library implements a window manager for Avalonia with windows defined using Avalonia instead of native windows. This gives you the ability to create MDI style user interfaces in Avalonia, even in environments which don't support windowing like Android and iOS.

Installation

To install you need to add a reference to the nuget package Iciclecreek.Avalonia.WindowManager

dotnet add package Iciclecreek.Avalonia.WindowManager

The window manager comes with a Light and Dark theme which you need to install into your app.xaml. To do that you need to:

• Add Iciclecreek.Avalonia.WindowManager namespace xmlns:wm="using:Iciclecreek.Avalonia.WindowManager"
• Add WindowManagerTheme

App.axaml

<Application xmlns="https://github.com/avaloniaui"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:wm="using:Iciclecreek.Avalonia.WindowManager"
             x:Class="Demo.App"
             RequestedThemeVariant="Default">
  <Application.Styles>
    <FluentTheme />
    <wm:WindowManagerTheme/>
  </Application.Styles>
</Application>

Usage

This library defines 2 classes:

• WindowManagerPanel - panel which hosts any content you want and also manages overlapping ManagedWindow instances
• ManagedWindow - a Window implementation which isn't native but instead 100% avalonia

WindowManagerPanel control

The WindowManagerPanel is a Canvas control which manages overlapping windows.

It has the following properties:

• Children - which is any children you want to have in the background of the window.
• Windows - which is enumeration of all of the windows the WindowManagerPanel owns.

And the following window oriented methods:

• ShowWindow(window) - Adds a window to the panel
• ShowAllWindows() - restores all windows
• MinimizeAllWindows() - Minimizes all windows.

ManagedWindow control

The ManagedWindow control is a clone of the Window control. It has standard Window properties like Title, WindowState, WindowStartupLocation, Position, etc. Instead of being hosted using Native windows, a ManagedWindow control is hosted by the WindowManagerPanel

Showing a window

To show a window you need to get an instance of the WindowManagerPanel and call ShowWindow().

For example:

  <wm:WindowMangerPanel Name="WindowManager"/>

And code behind

   var window = new ManagedWindow()
   {
       Title = "My window",
       WindowStartupLocation=WindowStartupLocation.CenterScreen,
       Width=300, Height=300
   };
    WindowManager.ShowWindow(window);

To close a window you simple call Close().

Showing a Dialog

To show a dialog is exactly the same as Avalonia, you instantiate a ManagedWindow and call **.ShowDialog() **passing in the parent window.

   var dialogWindow = new ManagedWindow()
   {
       Title = "My window",
       WindowStartupLocation=WindowStartupLocation.CenterScreen,
       Width=300, Height=300
   };
    var result = await dialogWindow.ShowDialog<string>(this);

To close a dialog you call Close(result);
