MGUI is a UI framework for MonoGame (Src) that features a powerful layout engine and data binding engine similar to WPF, and a robust set of controls to build your UI with.
All control names are prefixed with 'MG' and many controls have similar names and properties to what you might find in WPF. Currently supported controls:
- 'Container'-like Controls that define their own logic for arranging their children:
- MGDockPanel
- MGGrid
- MGOverlayPanel
- MGStackPanel
- MGUniformGrid
- Controls that can have child Content:
- MGBorder
- MGButton
- MGCheckBox
- MGComboBox
- MGContextMenu
- MGContextMenuItem
- MGXAMLDesigner
- MGExpander
- MGGroupBox
- MGListBox
- MGListView
- MGProgressButton
- MGRadioButton
- MGScrollViewer
- MGTabControl
- MGTabItem
- MGToggleButton
- MGToolTip
- MGWindow
- Controls that cannot have child Content:
- MGGridSplitter
- MGImage
- MGPasswordBox
- MGProgressBar
- MGRatingControl
- MGResizeGrip
- MGSeparator
- MGSlider
- MGStopwatch
- MGTextBlock
- MGTextBox
- MGTimer
Wiki is under construction. More documentation coming soon... maybe...

</Window>MGUI can also parse and render your XAML markup at runtime using the MGXAMLDesigner control:
- Clone this repo
- Use Visual Studio 2022 or later (since this project targets .NET 6.0, and makes use of some new-ish C# language features such as record structs (which may be unavailable in c# language version 8.0 or earlier))
- In your MonoGame project:
- In the Solution Explorer:
- Right-click your Solution, Add -> Existing Project. Browse for
MGUI.Shared.csproj, andMGUI.Core.csproj. - Right-click your Project, Add -> Project Reference. Add references to
MGUI.SharedandMGUI.Core. - You may need to:
- Right-click your game's Content folder, Add -> Existing Item. Browse for
MGUI\MGUI.Shared\Content\MGUI.Shared.Content.mgcbandMGUI\MGUI.Core\Content\MGUI.Core.Content.mgcband add them both as links (in the file browser dialog, click the dropdown arrow next to the Add button and choose Add as link). This step will ensure that MGUI's content .xnb files are copied to your project's bin\Content folder. This step might not be necessary.
- Right-click your game's Content folder, Add -> Existing Item. Browse for
- Right-click your Solution, Add -> Existing Project. Browse for
- In your Game class:
- In the Initialize method:
- Instantiate
MGUI.Shared.Rendering.MainRenderer - Instantiate
MGUI.Core.UI.MGDesktop
- Instantiate
- Anywhere in your code, instantiate 1 or more
MGWindowand add them to yourMGDesktopinstance viaMGDesktop.Windows - In the Update method: Call
MGDesktop.Update() - In the Draw method: Call
MGDesktop.Draw()
- In the Initialize method:
- In the Solution Explorer:
Example code for your Game class:
public class Game1 : Game, IObservableUpdate
{
private GraphicsDeviceManager _graphics;
private SpriteBatch _spriteBatch;
private MainRenderer MGUIRenderer { get; set; }
private MGDesktop Desktop { get; set; }
public event EventHandler<TimeSpan> PreviewUpdate;
public event EventHandler<EventArgs> EndUpdate;
public Game1()
{
_graphics = new GraphicsDeviceManager(this);
Content.RootDirectory = "Content";
IsMouseVisible = true;
}
protected override void Initialize()
{
this.MGUIRenderer = new(new GameRenderHost<Game1>(this));
this.Desktop = new(MGUIRenderer);
MGWindow Window1 = new(Desktop, 50, 50, 500, 200);
Window1.TitleText = "Sample Window with a single [b]Button[/b]: [color=yellow]Click it![/color]";
Window1.BackgroundBrush.NormalValue = new MGSolidFillBrush(Color.Orange);
Window1.Padding = new(15);
MGButton Button1 = new(Window1, button => { button.SetContent("I've been clicked!"); });
Button1.SetContent("Click me!");
Window1.SetContent(Button1);
this.Desktop.Windows.Add(Window1);
base.Initialize();
}
protected override void LoadContent()
{
_spriteBatch = new SpriteBatch(GraphicsDevice);
}
protected override void Update(GameTime gameTime)
{
PreviewUpdate?.Invoke(this, gameTime.TotalGameTime);
// Call Desktop.Update() at start of your update loop, so that the UI has the 1st-chance to receive and handle user-inputs
Desktop.Update();
// TODO: Add your game update logic here
base.Update(gameTime);
EndUpdate?.Invoke(this, EventArgs.Empty);
}
protected override void Draw(GameTime gameTime)
{
GraphicsDevice.Clear(Color.CornflowerBlue);
// TODO: Add your drawing code here
// Call Desktop.Draw() at the end of your draw loop, so that the UI is rendered overtop of everything else
Desktop.Draw();
base.Draw(gameTime);
}
}
MGUI.Core targets net6.0-windows by default. If you wish to use MGUI on another OS, open MGUI\MGUI.Core\MGUI.Core.csproj and change <TargetFramework>net6.0-windows</TargetFramework> to <TargetFramework>net6.0</TargetFramework>. Some features have better implementations when targeting net6.0-windows, but everything probably™ works fine when targeting net6.0. In particular, targeting net6.0 breaks some intellisense related to MarkupExtensions (such as MGBinding) when using the Visual Studio Xaml designer (but it still works at runtime, don't ask me why).
MGUI uses its own framework to detect and respond to inputs.
InputTracker- The base-class for input-related logic
- Uusually only 1 instance per program, automatically created when you create an instance of
MGUI.Shared.Rendering.MainRenderer - Contains 2 child objects:
MouseTrackerandKeyboardTracker
MouseTracker- Detects changes to the
MouseStateand stores information about those changes inEventArgobjects, most of which have anIsHandledproperty. - Manages 0 to many
MouseHandlers MouseHandler- Exposes several events that your code can subscribe to, to react to mouse events. Such as:
Scrolled,MovedInside,MovedOutside,Entered,Exited,PressedInside,PressedOutside,ReleasedInside,ReleasedOutside,DragStart,Dragged,DragEnd
- Prevents the same event from being invoked to several subscribers after one of the subscribers handles it (by setting
IsHandledtotrue)
- Exposes several events that your code can subscribe to, to react to mouse events. Such as:
- Detects changes to the
KeyboardTracker- Just like
MouseTrackerexcept for managing Keyboard-related inputs.
- Just like
If you'd like to utilize this framework in your own code, get the MouseTracker and/or KeyboardTracker instance from the InputTracker. Call MouseTracker.CreateHandler(...)/KeyboardTracker.CreateHandler(...), and subscribe to the events in the returned handler instance.
EX: Creates a MouseHandler instance in Game1.Initialize and subscribes to an event
public class Game1 : Game, IObservableUpdate, IMouseHandlerHost
{
private MainRenderer MGUIRenderer { get; set; }
private MGDesktop Desktop { get; set; }
// IObservableUpdate implementation
public event EventHandler<TimeSpan> PreviewUpdate;
public event EventHandler<EventArgs> EndUpdate;
// IMouseHandlerHost implementation
bool IMouseViewport.IsInside(Vector2 Position) => Window.ClientBounds.Contains(Position);
Vector2 IMouseViewport.GetOffset() => Vector2.Zero;
private MouseHandler MH { get; set; }
protected override void Initialize()
{
this.MGUIRenderer = new MainRenderer(new GameRenderHost<Game1>(this));
this.Desktop = new MGDesktop(MGUIRenderer);
// Create a MouseHandler
this.MH = MGUIRenderer.Input.Mouse.CreateHandler(this, null);
// Subscribe to 1 or more mouse-related events
MH.MovedInside += (sender, e) =>
{
// TODO: Do something in response to the mouse moving
};
base.Initialize();
}
protected override void Update(GameTime gameTime)
{
PreviewUpdate?.Invoke(this, gameTime.TotalGameTime);
Desktop.Update();
MH.ManualUpdate();
// TODO: Add your update logic here
base.Update(gameTime);
EndUpdate?.Invoke(this, EventArgs.Empty);
}
// constructor and other functions ommitted for brevity...
}Full example code:
Suppose you want to react to WASD keys to move your player, but you don't want to move the player if the WASD was handled by an MGTextBox on the UI:
public class Game1 : Game, IObservableUpdate, IKeyboardHandlerHost
{
private GraphicsDeviceManager _graphics;
private SpriteBatch _spriteBatch;
private MainRenderer MGUIRenderer { get; set; }
private MGDesktop Desktop { get; set; }
public event EventHandler<TimeSpan> PreviewUpdate;
public event EventHandler<EventArgs> EndUpdate;
public Game1()
{
_graphics = new GraphicsDeviceManager(this);
Content.RootDirectory = "Content";
IsMouseVisible = true;
}
private KeyboardHandler PlayerMovementHandler;
protected override void Initialize()
{
_graphics.PreferredBackBufferWidth = 400;
_graphics.PreferredBackBufferHeight = 300;
_graphics.ApplyChanges();
this.MGUIRenderer = new(new GameRenderHost<Game1>(this));
this.Desktop = new(MGUIRenderer);
// Create a simple UI that may need to handle keyboard events
MGWindow Window1 = new(Desktop, 20, 20, 200, 100);

}If you don't want to use MGUI's input framework, then you can just check if the EventArgs in MouseTracker/KeyboardTracker have already been handled before your code attempts to handle them:
BaseKeyPressedEventArgs W_PressEvent = MGUIRenderer.Input.Keyboard.CurrentKeyPressedEvents[Keys.W];
if (Keyboard.GetState().IsKeyDown(Keys.W) && (W_PressEvent == null || !W_PressEvent.IsHandled))
{
//TODO do something
}MGUI has its own DataBinding engine to allow you to bind UI data to data in your DataContext. Set MGWindow.WindowDataContext or MGElement.DataContextOverride. Then you can use the MGBinding markup extension in XAML to configure your bindings.
<Window xmlns="clr-namespace:MGUI.Core.UI.XAML;assembly=MGUI.Core"
SizeToContent="WidthAndHeight" TitleText="DataBindings" Padding="10">
<TextBlock Text="{MGBinding Path=SomeSampleString, Mode=OneWay}" />
</Window>{MGBinding Path=SomeSampleString, Mode=OneWay} creates a DataBinding that will automatically set TextBlock.Text = TextBlock.DataContext.SomeSampleString;
MGUI's DataBinding engine supports several features such as:
- Binding Modes (
OneTime,OneWay,OneWayToSource,TwoWay) - Binding to nested properties (
{MGBinding Path=Foo.Bar}) - Binding to specific named elements (
{MGBinding ElementName=SomeNamedCheckBox, Path=IsChecked}) - Binding with a
Converter({MGBinding Path=SomeValue, Converter={local:BoolToVisibilityConverter}}) - Binding with a
StringFormat({MGBinding Path=SomeFloatValue, StringFormat={}{0:0.0}}) - and more. Check the DataBinding window in the Samples project for detailed documentation:
Because MGUI uses its own DataBinding engine, DataBindings will work even on non-Windows platforms. (Though you will need to change MGUI.Core to target net6.0 instead of net6.0-windows, and some intellisense won't work in the Visual Studio Xaml designer.)
