72 | ``` 73 | 74 | ### Get instance of VirtualDesktop class 75 | ```csharp 76 | // Get all virtual desktops 77 | var desktops = VirtualDesktop.GetDesktops(); 78 | 79 | // Get Virtual Desktop for specific window 80 | var desktop = VirtualDesktop.FromHwnd(hwnd); 81 | 82 | // Get the left/right desktop 83 | var left = desktop.GetLeft(); 84 | var right = desktop.GetRight(); 85 | ``` 86 | 87 | ### Manage virtual desktops 88 | ```csharp 89 | // Create new 90 | var desktop = VirtualDesktop.Create(); 91 | 92 | // Remove 93 | desktop.Remove(); 94 | 95 | // Switch 96 | desktop.GetLeft().Switch(); 97 | ``` 98 | 99 | ### Subscribe virtual desktop events 100 | ```csharp 101 | // Notification of desktop switching 102 | VirtualDesktop.CurrentChanged += (_, args) => Console.WriteLine($"Switched: {args.NewDesktop.Name}"); 103 | 104 | // Notification of desktop creating 105 | VirtualDesktop.Created += (_, desktop) => desktop.Switch(); 106 | ``` 107 | 108 | ### for WPF window 109 | ```csharp 110 | // Need to install 'VirtualDesktop.WPF' package 111 | 112 | // Check whether a window is on the current desktop. 113 | var isCurrent = window.IsCurrentVirtualDesktop(); 114 | 115 | // Get Virtual Desktop for WPF window 116 | var desktop = window.GetCurrentDesktop(); 117 | 118 | // Move window to specific Virtual Desktop 119 | window.MoveToDesktop(desktop); 120 | 121 | // Pin window 122 | window.Pin() 123 | ``` 124 | 125 | ### See also: 126 | * [samples/README.md](samples/README.md) 127 | 128 | 129 | ## License 130 | 131 | This library is under [the MIT License](https://github.com/Grabacr07/VirtualDesktop/blob/master/LICENSE). 132 | -------------------------------------------------------------------------------- /samples/README.md: -------------------------------------------------------------------------------- 1 | ## Samples 2 | 3 | * [VirtualDesktop.Showcase](VirtualDesktop.Showcase) … A simple application uses the VirtualDesktop library, included in this repository. 4 | * [SylphyHorn](https://github.com/Grabacr07/SylphyHorn) … Utility app for Windows by the same author. 5 | -------------------------------------------------------------------------------- /samples/VirtualDesktop.Showcase/App.xaml: -------------------------------------------------------------------------------- 1 |  5 | 6 | 7 | 8 | 9 | -------------------------------------------------------------------------------- /samples/VirtualDesktop.Showcase/App.xaml.cs: -------------------------------------------------------------------------------- 1 | using System;
