Itp.WpfAppBar

Implementation of an AppBar in WPF based off of Using Application Desktop Toolbars and Extend the Windows 95 Shell with Application Desktop Toolbars.

Goals:

• Allow dock to any side of the screen
• Allow dock to a particular monitor
• Allow resizing of the appbar
• Handle screen layout changes and monitor disconnections
• Handle Win + Shift + Left and attempts to minimize or move the window
• Handle co-operation with other appbars (OneNote et al.)
• Handle per-monitor DPI scaling

Example use

<apb:AppBarWindow x:Class="WpfAppBarDemo.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:apb="clr-namespace:WpfAppBar;assembly=WpfAppBar"
    DataContext="{Binding RelativeSource={RelativeSource Self}}" Title="MainWindow" 
    DockedWidthOrHeight="200" MinWidth="100" MinHeight="100">
    <Grid>
        <Button x:Name="btClose" Content="Close" HorizontalAlignment="Left" VerticalAlignment="Top" Width="75" Height="23" Margin="10,10,0,0" Click="btClose_Click"/>
        <ComboBox x:Name="cbMonitor" SelectedItem="{Binding Path=Monitor, Mode=TwoWay}" HorizontalAlignment="Left" VerticalAlignment="Top" Width="120" Margin="10,38,0,0"/>
        <ComboBox x:Name="cbEdge" SelectedItem="{Binding Path=DockMode, Mode=TwoWay}" HorizontalAlignment="Left" Margin="10,65,0,0" VerticalAlignment="Top" Width="120"/>

        <Thumb Width="5" HorizontalAlignment="Right" Background="Gray" x:Name="rzThumb" Cursor="SizeWE" DragCompleted="rzThumb_DragCompleted" />
    </Grid>
</apb:AppBarWindow>

Codebehind:

public partial class MainWindow
{
    public MainWindow()
    {
        InitializeComponent();

        this.cbEdge.ItemsSource = new[]
        {
            AppBarDockMode.Left,
            AppBarDockMode.Right,
            AppBarDockMode.Top,
            AppBarDockMode.Bottom
        };
        this.cbMonitor.ItemsSource = MonitorInfo.GetAllMonitors();
    }

    private void btClose_Click(object sender, RoutedEventArgs e)
    {
        Close();
    }

    private void rzThumb_DragCompleted(object sender, DragCompletedEventArgs e)
    {
        this.DockedWidthOrHeight += (int)(e.HorizontalChange / VisualTreeHelper.GetDpi(this).PixelsPerDip);
    }
}

Add Nuget or clone from GitHub if you want to use it. The library itself is only three files, and can easily be dropped in a project.

Itp.WinFormsAppBar

A WinForms variant also is available under Itp.WinFormsAppBar. Edit Form1.cs to inherit from AppBarForm instead of Form.
See (Itp.WinFormsAppBar.Demo) for full demo.

public partial class Form1 : AppBarForm
{
    public Form1()
    {
    }
}

Winforms Safe Context

When using Itp.WinFormsAppBar you must update Program.cs to use SystemEventsSafeAppContext to avoid hangs on exit. Change:

Application.Run(new Form1());

to

Application.Run(new SystemEventsSafeAppContext(new Form1()));
