## Styling and Data Binding
|
||||
|
||||
OpenMaui supports the full MAUI styling and data binding infrastructure:
|
||||
|
||||
### XAML Styles
|
||||
```xml
|
||||
<ContentPage.Resources>
|
||||
<ResourceDictionary>
|
||||
<Color x:Key="PrimaryColor">#5C6BC0</Color>
|
||||
<Style TargetType="Button">
|
||||
<Setter Property="BackgroundColor" Value="{StaticResource PrimaryColor}" />
|
||||
<Setter Property="TextColor" Value="White" />
|
||||
</Style>
|
||||
</ResourceDictionary>
|
||||
</ContentPage.Resources>
|
||||
```
|
||||
|
||||
### Data Binding
|
||||
```xml
|
||||
<Label Text="{Binding Title}" />
|
||||
<Entry Text="{Binding Username, Mode=TwoWay}" />
|
||||
<Button Command="{Binding SaveCommand}" IsEnabled="{Binding CanSave}" />
|
||||
```
|
||||
|
||||
### Visual State Manager
|
||||
All interactive controls support VSM states: Normal, PointerOver, Pressed, Focused, Disabled.
|
||||
|
||||
```xml
|
||||
<Button Text="Hover Me">
|
||||
<VisualStateManager.VisualStateGroups>
|
||||
<VisualStateGroup x:Name="CommonStates">
|
||||
<VisualState x:Name="Normal">

# Frequently Asked Questions
|
||||
|
||||
## Visual Studio Integration
|
||||
|
||||
### How do I add Linux support to my existing MAUI project?
|
||||
|
||||
Unlike Android, iOS, and Windows which appear in Visual Studio's platform dropdown, Linux requires manual configuration since it's a community platform.
|
||||
|
||||
**Step 1: Add the NuGet Package**
|
||||
|
||||
```bash
|
||||
dotnet add package OpenMaui.Controls.Linux --prerelease
|
||||
```
|
||||
|
||||
Or in Visual Studio: Right-click project → Manage NuGet Packages → Search "OpenMaui.Controls.Linux"
|
||||
|
||||
**Step 2: Create a Linux Startup Project**
|
||||
|
||||
Create a new folder called `Platforms/Linux` in your project and add a `Program.cs`:
|
||||
|
||||
```csharp
|
||||
using OpenMaui.Platform.Linux;
|
||||
|
||||
namespace MyApp.Platforms.Linux;
|
||||
|
||||
public class Program
|
||||
{
|
||||
public static void Main(string[] args)
|
||||
{
|
||||
var app = new LinuxApplication();
|
||||
app.MainPage = new MainPage(); // Your existing MainPage
|
||||
app.Run();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Step 3: Add a Linux Build Configuration**
|
||||
|
||||
Add to your `.csproj`:
|
||||
|
||||
```xml
|
||||
<PropertyGroup Condition="'$(Configuration)|$(TargetFramework)'=='Debug|net9.0'">
|
||||
<RuntimeIdentifier>linux-x64</RuntimeIdentifier>
|
||||
</PropertyGroup>
|
||||
```
|
||||
|
||||
Or create a separate `MyApp.Linux.csproj` that references your shared code.
|
||||
|
||||
---
|
||||
|
||||
### Why doesn't Linux appear in Visual Studio's platform dropdown?
|
||||
|
||||
Visual Studio's MAUI tooling only shows platforms officially supported by Microsoft (.NET MAUI team). Linux is a community-supported platform through OpenMaui.
|
||||
|
||||
**Workarounds:**
|
||||
|
||||
1. **Use a separate Linux project** - Create a dedicated `MyApp.Linux` console project
|
||||
2. **Use VS Code** - Better cross-platform support with command-line builds
|
||||
3. **Use JetBrains Rider** - Excellent Linux and cross-platform support
|
||||
4. **Command line** - `dotnet build -r linux-x64` works from any IDE
|
||||
|
||||
---
|
||||
|
||||
### How do I build for Linux from Visual Studio on Windows?
|
||||
|
||||
**Option A: Command Line (Recommended)**
|
||||
|
||||
Open Terminal in VS and run:
|
||||
```bash
|
||||
dotnet build -c Release -r linux-x64
|
||||
dotnet publish -c Release -r linux-x64 --self-contained
|
||||
```
|
||||
|
||||
**Option B: Custom Build Profile**
|
||||
|
||||
1. Right-click solution → Properties → Configuration Manager
|
||||
2. Create a new configuration called "Linux"
|
||||
3. Edit project properties to set RuntimeIdentifier for this configuration
|
||||
|
||||
**Option C: WSL Integration**
|
||||
|
||||
If you have WSL (Windows Subsystem for Linux) installed:
|
||||
```bash
|
||||
wsl dotnet build
|
||||
wsl dotnet run
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
### How do I debug Linux apps from Windows?
|
||||
|
||||
**Option 1: Remote Debugging**
|
||||
|
||||
1. Install `vsdbg` on your Linux machine
|
||||
2. Configure remote debugging in VS/VS Code
|
||||
3. Attach to the running process
|
||||
|
||||
**Option 2: WSL (Recommended for development)**
|
||||
|
||||
1. Install WSL 2 with Ubuntu
|
||||
2. Install .NET SDK in WSL
|
||||
3. Run your app in WSL with X11 forwarding:
|
||||
```bash
|
||||
export DISPLAY=:0
|
||||
dotnet run
|
||||
```
|
||||
4. Use WSLg (Windows 11) for native GUI support
|
||||
|
||||
**Option 3: Virtual Machine**
|
||||
|
||||
1. Set up a Linux VM (VMware, VirtualBox, Hyper-V)
|
||||
2. Share your project folder
|
||||
3. Build and run inside the VM
|
||||
|
||||

|
||||
|
||||
## Project Structure
|
||||
|
||||
### What's the recommended project structure for cross-platform MAUI with Linux?
|
||||
|
||||
```
|
||||
MyApp/
|
||||
├── MyApp.sln
|
||||
├── MyApp/ # Shared MAUI project
|
||||
│ ├── MyApp.csproj
|
||||
│ ├── App.xaml
|
||||
│ ├── MainPage.xaml
|
||||
│ ├── Platforms/
|
||||
│ │ ├── Android/
|
||||
│ │ ├── iOS/
|
||||
│ │ ├── Windows/
|
||||
│ │ └── Linux/ # Add this folder
|
||||
│ │ └── Program.cs
|
||||
│ └── ...
|
||||
└── MyApp.Linux/ # Optional: Separate Linux project
|
||||
├── MyApp.Linux.csproj
|
||||
└── Program.cs
|
||||
```
|
||||
|
||||
### Should I use a separate project or add Linux to my existing project?
|
||||
|
||||
**Add to existing project** if:
|
||||
- You want a single codebase
|
||||
- Your MAUI code is mostly XAML-based
|
||||
- You're comfortable with conditional compilation
|
||||
|
||||
**Use a separate project** if:
|
||||
- You want cleaner separation
|
||||
- You need Linux-specific features
|
||||
- You want independent build/deploy cycles
|
||||
- Your team includes Linux specialists
|
||||
|
||||
---
|
||||
|
||||
## Build & Deploy
|
||||
|
||||
### How do I create a Linux executable?
|
||||
|
||||
```bash
|
||||
# Self-contained (includes .NET runtime)
|
||||
dotnet publish -c Release -r linux-x64 --self-contained -o ./publish
|
||||
|
||||
# Framework-dependent (smaller, requires .NET on target)
|
||||
dotnet publish -c Release -r linux-x64 --no-self-contained -o ./publish
|
||||
```
|
||||
|
||||
For ARM64 (Raspberry Pi, etc.):
|
||||
```bash
|
||||
dotnet publish -c Release -r linux-arm64 --self-contained -o ./publish
|
||||
```
|
||||
|
||||
### How do I create a .deb or .rpm package?
|
||||
|
||||
We recommend using packaging tools:
|
||||
|
||||
**For .deb (Debian/Ubuntu):**
|
||||
```bash
|
||||
dotnet tool install -g dotnet-deb
|
||||
dotnet deb -c Release -r linux-x64
|
||||
```
|
||||
|
||||
**For .rpm (Fedora/RHEL):**
|
||||
```bash
|
||||
dotnet tool install -g dotnet-rpm
|
||||
dotnet rpm -c Release -r linux-x64
|
||||
```
|
||||
|
||||
**For AppImage (Universal):**
|
||||
Use [AppImageKit](https://appimage.org/) with your published output.
|
||||
|
||||
**For Flatpak:**
|
||||
Create a flatpak manifest and build with `flatpak-builder`.
|
||||
|
||||

|
||||
|
||||
## Common Issues
|
||||
|
||||
### "SkiaSharp native library not found"
|
||||
|
||||
Install the required native libraries:
|
||||
|
||||
**Ubuntu/Debian:**
|
||||
```bash
|
||||
sudo apt-get install libfontconfig1 libfreetype6
|
||||
```
|
||||
|
||||
**Fedora:**
|
||||
```bash
|
||||
sudo dnf install fontconfig freetype
|
||||
```
|
||||
|
||||
### "Cannot open display" or "No display server"
|
||||
|
||||
Ensure X11 or Wayland is running:
|
||||
```bash
|
||||
echo $DISPLAY # Should show :0 or similar
|
||||
echo $WAYLAND_DISPLAY # For Wayland
|
||||
```
|
||||
|
||||
For headless/SSH sessions:
|
||||
```bash
|
||||
export DISPLAY=:0 # If X11 is running
|
||||
```
|
||||
|
||||
### "libX11.so not found"
|
||||
|
||||
Install X11 development libraries:
|
||||
|
||||
**Ubuntu/Debian:**
|
||||
```bash
|
||||
sudo apt-get install libx11-6 libx11-dev
|
||||
```
|
||||
|
||||
### App runs but window doesn't appear
|
||||
|
||||
Check if you're running under Wayland without XWayland:
|
||||
```bash
|
||||
# Force X11 mode
|
||||
export GDK_BACKEND=x11
|
||||
./MyApp
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## IDE Recommendations
|
||||
|
||||
### What's the best IDE for developing MAUI apps with Linux support?
|
||||
|
||||
| IDE | Linux Dev | Windows Dev | Pros | Cons |
|
||||
|-----|-----------|-------------|------|------|
|
||||
| **VS Code** | ⭐⭐⭐ | ⭐⭐⭐ | Cross-platform, lightweight, great C# extension | No visual XAML designer |
|
||||
| **JetBrains Rider** | ⭐⭐⭐ | ⭐⭐⭐ | Excellent cross-platform, powerful refactoring | Paid license |
|
||||
| **Visual Studio** | ⭐ | ⭐⭐⭐ | Best MAUI tooling on Windows | No native Linux support |
|
||||
| **Visual Studio Mac** | ⭐⭐ | N/A | Good MAUI support | macOS only |
|
||||
|
||||
**Our recommendation:**
|
||||
- **Windows developers:** Visual Studio for Android/iOS/Windows, VS Code or command line for Linux builds
|
||||
- **Linux developers:** JetBrains Rider or VS Code
|
||||
- **Cross-platform teams:** VS Code with standardized build scripts
|
||||

# OpenMaui Linux - Architecture Analysis & Implementation Notes
|
||||
|
||||
**Author:** Senior Architect Review
|
||||
**Date:** December 2025
|
||||
**Status:** Internal Document
|
||||
|
||||
---
|
||||
|
||||
## Executive Summary
|
||||
|
||||
OpenMaui Linux implements a custom SkiaSharp-based rendering stack for .NET MAUI on Linux. This document analyzes the architecture, identifies gaps, and tracks implementation of required improvements before 1.0 release.
|
||||
|
||||
---
|
||||
|
||||
## Architecture Overview
|
||||
|
||||
```
|
||||
┌─────────────────────────────────────┐
|
||||
│ .NET MAUI Controls │ ← Standard MAUI API
|
||||
├─────────────────────────────────────┤
|
||||
│ Linux Handlers (40+) │ ← Maps MAUI → Skia
|
||||
├─────────────────────────────────────┤
|
||||
│ SkiaView Controls (35+) │ ← Custom rendering
|
||||
├─────────────────────────────────────┤
|
||||
│ SkiaSharp + HarfBuzz │ ← Graphics/Text
|
||||
├─────────────────────────────────────┤
|
||||
│ X11 / Wayland │ ← Window management
|
||||
└─────────────────────────────────────┘
|
||||
```
|
||||
|
||||
### Design Decisions
|
||||
|
||||
| Decision | Rationale | Trade-off |
|
||||
|----------|-----------|-----------|
|
||||
| Custom rendering vs GTK/Qt wrapper | Pixel-perfect consistency, no toolkit dependencies | More code to maintain, no native look |
|
||||
| SkiaSharp for graphics | Hardware acceleration, cross-platform, mature | Large dependency |
|
||||
| HarfBuzz for text shaping | Industry standard, complex script support | Additional native dependency |
|
||||
| X11 primary, Wayland secondary | X11 more stable, XWayland provides compatibility | Native Wayland features limited |
|
||||
|
||||
---
|
||||
|
||||
## Strengths
|
||||
|
||||
1. **Pixel-perfect consistency** - Controls look identical across all Linux distros
|
||||
2. **No GTK/Qt dependency** - Simpler deployment, no version conflicts
|
||||
3. **Full control over rendering** - Can implement any visual effect
|
||||
4. **HiDPI support** - Proper scaling without toolkit quirks
|
||||
5. **Single codebase** - No platform-specific control implementations
|
||||
6. **BindableProperty support** - Full XAML styling and data binding (RC1)
|
||||
7. **Visual State Manager** - State-based styling for interactive controls (RC1)
|
||||
|
||||

|
||||
|
||||

---
|
||||
|
||||
## Implementation Details
|
||||
|
||||
### 1. Dirty Region Invalidation
|
||||
|
||||
**Current Problem:**
|
||||
```csharp
|
||||
// Current: Redraws entire surface on any change
|
||||
public void InvalidateAll() { /* full redraw */ }
|
||||
```
|
||||
|
||||
**Solution:**
|
||||
```csharp
|
||||
// Track dirty regions per view
|
||||
private List<SKRect> _dirtyRegions = new();
|
||||
|
||||
public void InvalidateRegion(SKRect region)
|
||||
{
|
||||
_dirtyRegions.Add(region);
|
||||
ScheduleRender();
|
||||
}
|
||||
|
||||
public void Render()
|
||||
{
|
||||
if (_dirtyRegions.Count == 0) return;
|
||||
|
||||
// Merge overlapping regions
|
||||
var merged = MergeDirtyRegions(_dirtyRegions);
|
||||
|
||||
// Only redraw dirty areas
|
||||
foreach (var region in merged)
|
||||
{
|
||||
canvas.Save();
|
||||
canvas.ClipRect(region);
|
||||
RenderRegion(region);
|
||||
canvas.Restore();
|
||||
}
|
||||
|
||||
_dirtyRegions.Clear();
|
||||
}
|
||||
```
|
||||
|
||||
**Files to modify:**
|
||||
- `Rendering/SkiaRenderingEngine.cs`
|
||||
- `Views/SkiaView.cs` (add InvalidateRegion)
|
||||
|
||||
---
|
||||
|
||||
### 2. Font Fallback Chain
|
||||
|
||||
**Current Problem:**
|
||||
- Missing glyphs show as boxes
|
||||
- No emoji support
|
||||
- Complex scripts may fail
|
||||
|
||||
**Solution:**
|
||||
```csharp
|
||||
public class FontFallbackManager
|
||||
{
|
||||
private static readonly string[] FallbackFonts = new[]
|
||||
{
|
||||
"Noto Sans", // Primary
|
||||
"Noto Color Emoji", // Emoji
|
||||
"Noto Sans CJK", // CJK characters
|
||||
"Noto Sans Arabic", // RTL scripts
|
||||
"DejaVu Sans", // Fallback
|
||||
"Liberation Sans" // Final fallback
|
||||
};
|
||||
|
||||
public SKTypeface GetTypefaceForCodepoint(int codepoint, SKTypeface preferred)
|
||||
{
|
||||
if (preferred.ContainsGlyph(codepoint))
|
||||
return preferred;
|
||||
|
||||
foreach (var fontName in FallbackFonts)
|
||||
{
|
||||
var fallback = SKTypeface.FromFamilyName(fontName);
|
||||
if (fallback?.ContainsGlyph(codepoint) == true)
|
||||
return fallback;
|
||||
}
|
||||
|
||||
return preferred; // Use tofu box as last resort
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Files to modify:**
|
||||
- `Services/FontFallbackManager.cs` (new)
|
||||
- `Views/SkiaLabel.cs`
|
||||
- `Views/SkiaEntry.cs`
|
||||
- `Views/SkiaEditor.cs`
|
||||
|
||||
---
|
||||
|
||||
### 3. XDG Desktop Portal Integration
|
||||
|
||||
**Current Problem:**
|
||||
- File dialogs use basic X11
|
||||
- Don't match system theme
|
||||
- Missing features (recent files, bookmarks)
|
||||
|
||||
**Solution:**
|
||||
```csharp
|
||||
public class PortalFilePickerService : IFilePicker
|
||||
{
|
||||
private const string PortalBusName = "org.freedesktop.portal.Desktop";
|
||||
private const string FileChooserInterface = "org.freedesktop.portal.FileChooser";
|
||||
|
||||
public async Task<FileResult?> PickAsync(PickOptions options)
|
||||
{
|
||||
// Call portal via D-Bus
|
||||
var connection = Connection.Session;
|
||||
var portal = connection.CreateProxy<IFileChooser>(
|
||||
PortalBusName,
|
||||
"/org/freedesktop/portal/desktop");
|
||||
|
||||
var result = await portal.OpenFileAsync(

### 4. System Theme Detection
|
||||
|
||||
**Current Problem:**
|
||||
- Hard-coded colors
|
||||
- Ignores user's dark/light mode preference
|
||||
- Doesn't match desktop environment
|
||||
|
||||
**Solution:**
|
||||
```csharp
|
||||
public class SystemThemeService
|
||||
{
|
||||
public Theme CurrentTheme { get; private set; }
|
||||
public event EventHandler<ThemeChangedEventArgs>? ThemeChanged;
|
||||
|
||||
public SystemThemeService()
|
||||
{
|
||||
DetectTheme();
|
||||
WatchForChanges();
|
||||
}
|
||||
|
||||
private void DetectTheme()
|
||||
{
|
||||
// Try GNOME settings first
|
||||
var gsettings = TryGetGnomeColorScheme();
|
||||
if (gsettings != null)
|
||||
{
|
||||
CurrentTheme = gsettings.Contains("dark") ? Theme.Dark : Theme.Light;
|
||||
return;
|
||||
}
|
||||
|
||||
// Try KDE settings
|
||||
var kdeConfig = TryGetKdeColorScheme();
|
||||
if (kdeConfig != null)
|
||||
{
|
||||
CurrentTheme = kdeConfig;
|
||||
return;
|
||||
}
|
||||
|
||||
// Fallback to GTK settings
|
||||
CurrentTheme = TryGetGtkTheme() ?? Theme.Light;
|
||||
}
|
||||
|
||||
private string? TryGetGnomeColorScheme()
|
||||
{
|
||||
// gsettings get org.gnome.desktop.interface color-scheme
|
||||
// Returns: 'prefer-dark', 'prefer-light', or 'default'
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Files to modify:**
|
||||
- `Services/SystemThemeService.cs` (new)
|
||||
- `Services/LinuxResourcesProvider.cs` (use theme colors)
|
||||
|
||||

|
||||
|
||||
### 5. GPU Acceleration
|
||||
|
||||
**Current Problem:**
|
||||
- Software rendering only
|
||||
- CPU-bound for complex UIs
|
||||
- Animations not smooth
|
||||
|
||||
**Solution:**
|
||||
```csharp
|
||||
public class GpuRenderingEngine : IDisposable
|
||||
{
|
||||
private GRContext? _grContext;
|
||||
private GRBackendRenderTarget? _renderTarget;
|
||||
private SKSurface? _surface;
|
||||
|
||||
public void Initialize(IntPtr display, IntPtr window)
|
||||
{
|
||||
// Create OpenGL context
|
||||
var glInterface = GRGlInterface.CreateNativeGlInterface();
|
||||
_grContext = GRContext.CreateGl(glInterface);
|
||||
|
||||
// Create render target from window
|
||||
var framebufferInfo = new GRGlFramebufferInfo(0, SKColorType.Rgba8888.ToGlSizedFormat());
|
||||
_renderTarget = new GRBackendRenderTarget(width, height, 0, 8, framebufferInfo);
|
||||
|
||||
// Create accelerated surface
|
||||
_surface = SKSurface.Create(_grContext, _renderTarget, GRSurfaceOrigin.BottomLeft, SKColorType.Rgba8888);
|
||||
}
|
||||
|
||||
public void Render(SkiaView rootView, IEnumerable<SKRect> dirtyRegions)
|
||||
{
|
||||
var canvas = _surface.Canvas;
|
||||
|
||||
foreach (var region in dirtyRegions)
|
||||
{
|
||||
canvas.Save();
|
||||
canvas.ClipRect(region);
|
||||
rootView.Draw(canvas, region);
|
||||
canvas.Restore();
|
||||
}
|
||||
|
||||
canvas.Flush();
|
||||
_grContext.Submit();
|
||||
|
||||
// Swap buffers
|
||||
SwapBuffers();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Files to modify:**
|
||||
- `Rendering/GpuRenderingEngine.cs` (new)
|
||||
- `Rendering/SkiaRenderingEngine.cs` (refactor as CPU fallback)
|
||||
- `Window/X11Window.cs` (add GL context creation)
|
||||
|
||||
---
|
||||
|
||||
### 6. Virtualized List Recycling
|
||||
|
||||
**Current Problem:**
|
||||
- All items rendered even if off-screen
|
||||
- Memory grows with list size
|
||||
- Poor performance with large datasets
|
||||
|
||||
**Solution:**
|
||||
```csharp
|
||||
public class VirtualizingItemsPanel
|
||||
{
|
||||
private readonly Dictionary<int, SkiaView> _visibleItems = new();
|
||||
private readonly Queue<SkiaView> _recyclePool = new();
|
||||
|
||||
public void UpdateVisibleRange(int firstVisible, int lastVisible)
|
||||
{
|
||||
// Recycle items that scrolled out of view
|
||||
var toRecycle = _visibleItems
|
||||
.Where(kvp => kvp.Key < firstVisible || kvp.Key > lastVisible)
|
||||
.ToList();
|
||||
|
||||
foreach (var item in toRecycle)
|
||||
{
|
||||
_visibleItems.Remove(item.Key);
|
||||
ResetAndRecycle(item.Value);
|
||||
}
|
||||
|
||||
// Create/reuse items for newly visible range
|
||||
for (int i = firstVisible; i <= lastVisible; i++)
|
||||
{
|
||||
if (!_visibleItems.ContainsKey(i))
|
||||
{
|
||||
var view = GetOrCreateItemView();
|
||||
BindItemData(view, i);
|
||||
_visibleItems[i] = view;
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
private SkiaView GetOrCreateItemView()
|
||||
{
|
||||
return _recyclePool.Count > 0
|
||||
? _recyclePool.Dequeue()
|
||||
: CreateNewItemView();
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Files to modify:**
|
||||
- `Views/SkiaItemsView.cs`
|
||||
- `Views/SkiaCollectionView.cs`
|
||||
|
||||
