Westwind.Wpf.Statusbar 0.2.6

WPF Statusbar Helper and Control

This is a small WPF library that provides Statusbar functionality in a couple of different ways.

• A basic statusbar control
• A Statusbar Helper you can apply against your own status bars

Here's an in-app example of the StatusHelper in a live application in Markdown Monster.

Features

• Simple Status Bar Control
  A basic status bar control that has an icon plus 3 status panels that can be individually accessed and managed. Control wraps a Statusbar instance that you can optionally customize with additional panels and custom panel content. Various ShowStatusXXX() methods update the main panel's icon and text.

• A Status Bar Helper
  If you prefer to use your own layout for the Statusbar, you can instead use the StatusbarHelper to add the status bar update functionality to your own instances. Requires that your Statusbar has an icon Image control and a main TextBlock area to update which is handled via the helper's ShowStausXXX() methods.

Both of these tools provide the following features:

• Easy to use, single method status updates from anywhere in your app
• Modes: Success, Error, Warning, Progress
• Status relevant icons change based on display mode
• Icons are animated for attention
• Spinning icon support typically for progress operations
• Status messages and icons can be timed out, to revert
  back to a default status message and icon.
• Status updates immediately update UI even in synchronous code
• Stock icons provided
• Icon customization available for overriding either globally, per instance or per method using ImageSource

Installation

You can install this library from NuGet:

> dotnet add package Westwind.Wpf.Statusbar

or you can include the source code from this repository into your project.

Statusbar Control

The status bar control can just be dropped onto a form by adding the following namespace:

<Window x:Class="SampleApp.MainWindow" ...
        xmlns:statusbar="clr-namespace:Westwind.Wpf.Statusbar;assembly=Westwind.Wpf.Statusbar"
>

and the actual control:

<statusbar:StatusbarControl Grid.Row="1" x:Name="Statusbar" />

In a window it looks like this:

<Window x:Class="SampleApp.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        
        xmlns:statusbar="clr-namespace:Westwind.Wpf.Statusbar;assembly=Westwind.Wpf.Statusbar"
        
        Title="MainWindow" 
        Height="400" Width="450">


    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="*"/>
            <RowDefinition Height ="Auto"/>
        </Grid.RowDefinitions>

        <StackPanel Width="200" Margin="20">
        ... Content here
        </StackPanel>

        <statusbar:StatusbarControl Grid.Row="1" Name="Statusbar" />
    </Grid>
</Window>

Showing Status Messages

Once the control is on the page you can simply call the single line display methods to manipulate the status behavior.

The following are examples that demonstrate individual status operations:

// shows status and resets to default after default timeout
Statusbar.ShowStatusSuccess("Yay. The operation was successful!");

// shows status and resets to default  after 2 secs
Statusbar.ShowStatusError("Ooops. Something went wrong!",2000);

// *** Access the embedded StatusbarHelper directly (Statusbar.Status)
// shows status and resets to default  after 2 secs
Statusbar.Status.ShowStatusWarning("Careful... this might go sideways.", 2000);

// shows spinning icon indefinitely
Statusbar.Status.ShowStatusProgress("This may take a minute...");

Note that you can either use the control's methods directly (first two examples) or you can use the Status property (last two) which uses the StatusbarHelper instance which is the core component.

Updating Non-Primary Panels

The various status methods can be used to update the status bar's primary text panel and icon, but you can also set the optional center and right panels and assign text or content.

// set with plain text
Statusbar.SetStatusCenter("Center Panel Text");

// set with control content
var sp = new StackPanel() { Orientation = Orientation.Horizontal };
sp.Children.Add(new TextBlock() { Text = "Right Panel Text" });
sp.Children.Add(new Image { Source = StatusIcons.Default.SuccessIcon, Height=15, Margin = new Thickness(3, 0 ,0, 0)});

Statusbar.SetStatusRight(sp);

// Update the primary panel's text only
Statusbar.StatusText.Text = "Pull it!";

Modifying the Statusbar Layout

The status bar control is a UserControl with an embedded StatusBar control which is named - StatusbarInstance that you can directly access and manipulate. This means you can optionally customize the layout by adding or removing panels and adding custom content beyond the base layout.

Need a custom StatusBar Layout? Use StatusbarHelper

If you plan on a custom Statusbar layout, my recommendation is to skip the control and use the StatusbarHelper on your own custom layout in your host Window or control instead. As long as you have an icon Image and main panel TextBlock you can use the StatusbarHelper to get all feature benefits plus full control over your StatusBar layout in your own XAML code.

Statusbar Helper

The StatusbarControl is a quick way to drop a basic status bar on a page, but if you want more control over your status bar layout you can also create and manage your own Status bar XAML layout. You can then attach the StatusbarHelper to take over the status message display.

Configuration

In order to use the StatusbarHelper class a few things are needed:

• A status bar with an icon Image control and a TextBlock main Status text control
• If you add a default icon from the default icon collection make sure to add the icons.xaml resources to the Window or App resources.
• Create a property to hold the StatusbarHelper instance
• Initialize and assign property after InitializeComponents()

Custom StatusBar XAML Configuration

For example you can embed a status bar control like this into your own Xaml with a default icon taken from the icons.xaml resources embedded in the library.

<Window x:Class="SampleApp.MainWindow" ...
        xmlns:statusbar="clr-namespace:Westwind.Wpf.Statusbar;assembly=Westwind.Wpf.Statusbar"
>
<Window.Resources>
 
 <ResourceDictionary Source="pack://application:,,,/Westwind.Wpf.Statusbar;component/Assets/icons.xaml" />
</Window.Resources>
...
   
<StatusBar  
    Height="30"  
    VerticalAlignment="Bottom" HorizontalAlignment="Stretch">
    <StatusBar.ItemsPanel>
        <ItemsPanelTemplate>
            <Grid>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="Auto" />
                    <ColumnDefinition Width="*" />
                    <ColumnDefinition Width="Auto" />
                    <ColumnDefinition Width="Auto"  />
                </Grid.ColumnDefinitions>
            </Grid>
        </ItemsPanelTemplate>
    </StatusBar.ItemsPanel>
 
    
    <StatusBarItem Grid.Column="0" Margin="2,1,0,0">
        <Image x:Name="StatusIcon" Source="{StaticResource circle_greenDrawingImage}" Height="14" />
    </StatusBarItem>
    
    
    <StatusBarItem Grid.Column="1">
        <TextBlock Name="StatusText">Ready</TextBlock>
    </StatusBarItem>
    
    
    <StatusBarItem Grid.Column="2">
        <ContentControl Name="StatusCenter" 
                   Margin="10 0"
                   x:FieldModifier="public" HorizontalAlignment="Left" />
    </StatusBarItem>
    <StatusBarItem Grid.Column="3">
        <ContentControl x:Name="StatusRight" x:FieldModifier="public" HorizontalAlignment="Right" Margin="0 0 5 0" />
    </StatusBarItem>
</StatusBar>

Status Bar Recommendations

For best effect, there are a couple of recommendations for any custom status bars you use with StatusbarHelper:

• Make the StatusBar a fixed height to avoid resizing on Flashing
• Make the icon a fixed height (13-15 is good)

Add the StatusbarHelper Instance Property

In the constructor of Window or Control that hosts this control you can then assign the StatusbarHelper as a property like this:

 public partial class MyWindow : Window
 {
    public StatusbarHelper Status { get;  }

    public MyWindow()
    {
        InitializeComponent();
          
        // Create the helper with text and icon passed in    
        Status = new StatusbarHelper(StatusText, StatusIcon);
        
        ...
    } 
 }        

Use the Status instance

To use, you can now call the helper's methods to update the status bar:

private void BtnSuccess_OnClick(object sender, RoutedEventArgs e)
{
    // use the controls methods - uses Default Timeout
    Status.ShowStatusSuccess("Yay. The operation was successful! ");
    
    // shows status and resets to default  after 2 secs
    Status.ShowStatusWarning("Careful... this might go sideways.", 2000);

    // shows spinning icon indefinitely
    Status.ShowStatusProgress("This may take a minute...");
}

Class Interface

The following provides more detail on the interfaces for the StatusbarControl and StatusHelper classes.

StatusbarControl

The StatusbarControl is a UserControl that contains a 3 panel StatusBar control. The

Properties

• StatusbarInstance
  the 4 panel WPF StatusBar instance you can optionally manipulate

• Status
  The StatusbarHelper instance that does all the work for updating the status bar (see below).

Methods

The control has several methods that forward the StatusbarHelper methods to the control (more info below).

• ShowStatusSuccess()
• ShowStatusError()
• ShowStatusWarning()
• ShowStatusProgress()

In addition it has two methods to set the 2 non-primary status bar panels, with content or text:

• SetStatusCenter()
• SetStatusRight()

StatusBarHelper

The helper provides easy to use methods to update the icon and main status text of the statusbar that it's bound to. You pass in a TextBlock and Image that map to these panel items and that are updated as needed.

Properties

• StatusText and StatusImage
  The two controls captured in the constructor that are updated by this helper.

• StatusIcons
  An instance of ItemSource images that describe the icons that are used for display messages. Defaults to StatusIcons.Default but can be overridden with your own instance that replaces any of the default ItemSource Images. If you replace StatusIcons we recommend you create a new instance to avoid overwriting the default icons unless you want to globally replace icons.

• DefaultStatusText
  The default status text that the control reverts back to when the display timeout is expired.
  <small>Related: The default icon is reset to StatusIcons.DefaultIcon.</small>

• StatusMessageTimeoutMs
  Determines the default message timeout in milliseconds for operations that revert to the default message and icon after the timeout (Success, Error, Warning). You can always override this setting in the individual methods.

• OriginalIconHeight and OriginalIconWidth
  Captures the original icon size of the icon so that it can be reset when 'flashing' the icon. If the value is non-zero the value provided is used. If default value of 0, we attempt to capture the size from the Image control, and if that fails - likely because of auto-sizing - we default to 14. Preferrably you set the icon's height in the statusbar or provide at least an explicit height. If width can't be determined we use the same value as the height.

Methods Methods are pretty self-explanatory:

public void ShowStatusSuccess(string message, int timeout = -1, 
    ImageSource imageSource = null, bool flashIcon = true)

public void ShowStatusWarning(string message, int timeout = -1,
    ImageSource imageSource = null,
    bool flashIcon = true)

public void ShowStatusWarning(string message, int timeout = -1,
    ImageSource imageSource = null,
    bool flashIcon = true)

public void ShowStatusProgress(string message, int timeout = -1, 
    ImageSource imageSource = null, bool spin = true, bool flashIcon = false)

public void ShowStatus(string message = null, 
    int timeoutMs = 0,
    ImageSource imageSource = null,
    bool spin = false, 
    bool flashIcon = false, 
    bool noDispatcher = false)

public void SetStatusIcon(ImageSource imageSource, bool spin = false)
public void SetStatusIcon() // resets to default

public void FlashIcon(Image icon = null)

Timeout Parameter Notes

The timeout parameter can be passed as a Milliseconds value, -1 or 0.

• Milliseconds - Explicit timeout in Milliseconds
• -1 - Use the default StatusMessageTimeoutMs
• 0 - No timeout - display the message and leave it up

Using Custom Icons

The status bar uses default icons that are internally provided via a icons.xaml XAML resource, but can be replaced with your own custom icons either globally, per instance or with each method call.

All icons are ImageSource objects, so they can be replaced with any new image source, which can come from other XAML resources, bitmap images or even from other libraries like the FontAwesome6 library - anything that can produce an ImageSource.

Default Icon Configuration - how it works

By default the StatusbarHelper and StatusbarControl are using default icons that are embedded as XAML resources in icons.xaml and that are assigned as DrawingImage instances to the ImageSource typed properties of StatusIcons.

The default resource icons are accessible via the following resource path and resource keys:

via XAML:

<Window.Resources>
 
 <ResourceDictionary Source="pack://application:,,,/Westwind.Wpf.Statusbar;component/Assets/icons.xaml" />
</Window.Resources>

<StatusBarItem Grid.Column="0" Margin="2,1,0,0">
        <Image x:Name="StatusIcon" Source="{StaticResource circle_greenDrawingImage}" Height="14" />
</StatusBarItem>

or via code:

public StatusIcons()
{
    var dict = new ResourceDictionary()
    {
        Source = new Uri("pack://application:,,,/Westwind.Wpf.Statusbar;component/Assets/icons.xaml")
    };
    if (!Application.Current.Resources.Contains("circle_greenDrawingImage"))
        Application.Current.Resources.MergedDictionaries.Add(dict);

    DefaultIcon = dict["circle_greenDrawingImage"] as DrawingImage;
    SuccessIcon = dict["circle_checkDrawingImage"] as DrawingImage;
    ErrorIcon = dict["triangle_exclamationDrawingImage"] as DrawingImage;
    WarningIcon = dict["triangle_warningDrawingImage"] as DrawingImage;
    ProgressIcon = dict["circle_notchDrawingImage"] as DrawingImage;
}

These icons are exposed as the default in:

StatusbarHelper.StatusIcons = StatusbarIcons.Default;

Overriding Default Icons

There are three ways to override the default icons:

• Globally - Overide the StatusIcon.Default icon set
• Per Control - Override the StatusbarHelper.StatusIcons instance
• Per Call - Override the imageSource parameter on the various ShowStatusXXX() calls

Globally override StatusIcon.Default

The StatusIcon.Default static object contains the default icons provided by this library in the icons.xaml resource. The default icons are the default icon set assigned to a new instance of the StatusbarHelper and by extension the StatusbarControl which uses the helper for rendering.

You can assign a new set of icons to the StatusIcon.Default icon ImageSource properties. By overriding these ImageSource properties before any controls or helpers are created you are effectively globally overriding the value all icons that are rendered.

For example, to override the SuccessIcon you could use the following code:

// ImageAwesome creates a DrawingImage control
image = new ImageAwesome()
{
    PrimaryColor = Brushes.ForestGreen,
    Height = 15,
    Icon = EFontAwesomeIcon.Solid_SquareCheck
};

// globally override SuccessIcon for all instance that use the default icons
StatusIcons.Default.SuccessIcon = image.Source;

Override StatusbarHelper Instance

If you want to override behavior of a single StatusbarHelper or StatusbarControl you can do so via the Helper's StatusIcons class. You access it both directly on a StatusbarHelper.StatusIcons instance or on the StatusbarControl.Status.StatusIcons property.

Here's an example using the FontAwesome6 library which among other things can create ImageSources from FontAwesome icons using the ImageAwesome class. Here I'm assigning to a StatusbarControl and it's StatusIcons at the control level.

private void BtnToggleIcons_OnChecked(object sender, RoutedEventArgs e)
{
    ToggleState = !ToggleState;

    if (ToggleState)
    {
        ActiveIconSet = "Custom Images: Font Awesome 6";

        // You can override the control or StatusbarHelper icons

        // Create and assign a NEW icon set so we don't overwrite default icons
        var icons = new StatusIcons();
        Statusbar.Status.StatusIcons = icons;
        
        // if you want to retain existing icons assign them
        // icons.DefaultIcon = StatusIcons.Default.DefaultIcon

        // create new custom icons for the error icon from FontAwesome6 icons
        var image = new ImageAwesome()
        {
            PrimaryColor = Brushes.Green,
            Height = 15,
            Icon = EFontAwesomeIcon.Solid_House
        };
        icons.DefaultIcon = image.Source;

        image = new ImageAwesome()
        {
            PrimaryColor = Brushes.ForestGreen,
            Height = 15,
            Icon = EFontAwesomeIcon.Solid_SquareCheck
        };
        icons.SuccessIcon = image.Source;

        // create a custom icon for the error icon from FontAwesome6 icons
        image = new ImageAwesome()
        {
            PrimaryColor = Brushes.DarkGoldenrod,
            Height = 15,
            Icon = EFontAwesomeIcon.Solid_CircleRadiation
        };
        icons.WarningIcon = image.Source;

        image = new ImageAwesome()
        {
            PrimaryColor = Brushes.Firebrick,
            Height = 15,
            Icon = EFontAwesomeIcon.Solid_CircleExclamation
        };
        icons.ErrorIcon = image.Source;

        image = new ImageAwesome()
        {
            PrimaryColor = Brushes.SteelBlue,
            Height = 15,
            Icon = EFontAwesomeIcon.Solid_Spinner
        };
        icons.ProgressIcon = image.Source;
    }
    else
    {
        ActiveIconSet = "Default Xaml Icons";
        
        // using the Statusbar control
        Statusbar.Status.StatusIcons = StatusIcons.Default;
        
        // using the Statusbar Helper
        // StatusHelper.StatusIcons = icons;
    }

    btnToggleIcons.Content = ActiveIconSet;
    Statusbar.Status.SetStatusIcon();

    // Alternately you can also override the StatusIcon.Default icons 
    // and have them overridden anywhere the default icons are used
    // as a 'global' icon override:
    //
    // StatusbarIcons.DefaultIcon = image.Source;  // overrides anywhere the default is used

}

Per call Icon Overrides

Each of the control and helper ShowStatusXXX() methods have a parameter override that let you specify an imageSource parameter that effectively lets you use any icon you want for just a single call.

private async void BtnRaw_OnClick(object sender, RoutedEventArgs e)
{
    var image = new ImageAwesome()
    {
        PrimaryColor = Brushes.SteelBlue,
        Height = 15,
        Icon = EFontAwesomeIcon.Solid_Spinner
    };
    
    // Use the custom ImageAwesome source 
    Statusbar.Status.ShowStatusProgress("Custom icon spinner (from FontAwesome)",
                                       imageSource: image.Source, spin: true);
}
