# Terminal.Gui - Terminal UI toolkit for .NET
|
|
|
|
A simple UI toolkit for .NET, .NET Core, and Mono that works on Windows, the Mac, and Linux/Unix.
|
|
|
|
|
|
|
|
A presentation of this was part of the [Retro.NET](https://channel9.msdn.com/Events/dotnetConf/2018/S313) talk at .NET Conf 2018 [Slides](https://tirania.org/Retro.pdf)
|
|
|
|
## Controls
|
|
The toolkit contains various controls for building text user interfaces:
|
|
|
|
* [Buttons](https://migueldeicaza.github.io/gui.cs/api/Terminal.Gui/Terminal.Gui.Button.html)
|
|

|
|
|
|
In addition, a complete Xterm/Vt100 terminal emulator that you can embed is now part of [XtermSharp](https://github.com/migueldeicaza/XtermSharp/blob/master/GuiCsHost/TerminalView.cs) - you just need to pull the `TerminalView` linked here into your project.
|
|
|
|
## Features
|
|
|
|
* **Cross Platform** - Terminal drivers for Curses, [Windows Console](https://github.com/migueldeicaza/gui.cs/issues/27), and the .NET Console mean **Terminal.Gui** works well on both color and monochrome terminals and has mouse support on terminal emulators that support it.
|
|
* **Keyboard and Mouse Input** - Both keyboard and mouse input are supported, including limited support for drag & drop.
|
|
* **[Flexible Layout](https://migueldeicaza.github.io/gui.cs/articles/overview.html#layout)** - **Terminal.Gui** supports both *Absolute layout* and an innovative UI layout system referred to as *Computed Layout*. *Computed Layout* makes it easy to layout controls relative to each other and enables dynamic console GUIs.
|
|
* **Clipboard support** - Cut, Copy, and Paste of text provided through the `[Clipboard](https://migueldeicaza.github.io/gui.cs/api/Terminal.Gui/Terminal.Gui.Clipboard.html)` class.
|
|
* **[Arbitrary Views](https://migueldeicaza.github.io/gui.cs/api/Terminal.Gui/Terminal.Gui.View.html)** - All visible UI elements are subclasses of the `View` class, and these in turn can contain an arbitrary number of sub-views.
|
|
* **Advanced App Features** - The [Mainloop](https://migueldeicaza.github.io/gui.cs/api/Mono.Terminal/Mono.Terminal.MainLoop.html) supports processing events, idle handlers, timers, and monitoring file
|
|
descriptors.
|
|
|
|
### Keyboard Input Handling
|
|
|
|
The input handling of **Terminal.Gui** is similar in some ways to Emacs and the Midnight Commander, so you can expect some of the special key combinations to be active.
|
|
|
|
The key `ESC` can act as an Alt modifier (or Meta in Emacs parlance), to allow input on terminals that do not have an alt key. So to produce the sequence `Alt-F`, you can press either `Alt-F`, or `ESC` followed by the key `F`.
|
|
|
|
To enter the key `ESC`, you can either press `ESC` and wait 100 milliseconds, or you can press `ESC` twice.
|
|
|
|
`ESC-0`, and `ESC-1` through `ESC-9` have a special meaning, they map to `F10`, and `F1` to `F9` respectively.
|
|
|
|
**Terminal.Gui** respects common Mac and Windows keyboard idoms as well. For example, clipboard operations use the familiar `Control/Command-C, X, V` model.
|
|
|
|
`CTRL-Q` is used for exiting views (and apps).
|
|
|
|
### Driver model
|
|
|
|
Currently **Terminal.Gui** has support for `[ncurses](https://github.com/migueldeicaza/gui.cs/blob/master/Terminal.Gui/Drivers/CursesDriver.cs)`, [`System.Console`](https://github.com/migueldeicaza/gui.cs/blob/master/Terminal.Gui/Drivers/NetDriver.cs), and a full [Win32 Console](https://github.com/migueldeicaza/gui.cs/blob/master/Terminal.Gui/Drivers/WindowsDriver.cs) front-end.
|
|
|
|
`ncurses` is used on Mac/Linux/Unix with color support based on what your library is compiled with; the Windows driver supports full color and mouse, and an easy-to-debug `System.Console` can be used on Windows and Unix, but lacks mouse support.
|
|
|
|
You can force the use of `System.Console` on Unix as well; see `Core.cs`.
|
|
|
|
## Showcase
|
|
|
|
The [UI Catalog project](https://github.com/migueldeicaza/gui.cs/tree/master/UICatalog) provides an easy to use and extend sample illustrating the capabilities of **Terminal.Gui**.
|
|
|
|
## Documentation
|
|
|
|
* [API documentation](https://migueldeicaza.github.io/gui.cs/api/Terminal.Gui.html)
|
|
|
|
* [Overview](https://migueldeicaza.github.io/gui.cs/articles/overview.html) contains the conceptual documentation and a walkthrough of the core concepts of **Terminal.Gui**.
|
|

|
### Sample Usage
|
|
|
|
```csharp
|
|
using Terminal.Gui;
|
|
|
|
class Demo {
|
|
static void Main ()
|
|
{
|
|
Application.Init ();
|
|
var top = Application.Top;
|
|
|
|
// Creates the top-level window to show
|
|
var win = new Window ("MyApp") {
|
|
X = 0,
|
|
Y = 1, // Leave one row for the toplevel menu
|
|
|
|
// By using Dim.Fill(), it will automatically resize without manual intervention
|
|
Width = Dim.Fill (),
|
|
Height = Dim.Fill ()
|
|
};
|
|
top.Add (win);
|
|
|
|
// Creates a menubar, the item "New" has a help menu.
|
|
var menu = new MenuBar (new MenuBarItem [] {
|
|
new MenuBarItem ("_File", new MenuItem [] {
|
|
new MenuItem ("_New", "Creates new file", NewFile),
|
|
new MenuItem ("_Close", "", () => Close ()),
|
|
new MenuItem ("_Quit", "", () => { if (Quit ()) top.Running = false; })
|
|
}),
|
|
new MenuBarItem ("_Edit", new MenuItem [] {
|
|
new MenuItem ("_Copy", "", null),
|
|
new MenuItem ("C_ut", "", null),
|
|
new MenuItem ("_Paste", "", null)
|
|
})
|
|
});
|
|
top.Add (menu);
|
|
|
|
var login = new Label ("Login: ") { X = 3, Y = 2 };
|
|
var password = new Label ("Password: ") {
|
|
X = Pos.Left (login),
|
|
Y = Pos.Top (login) + 1
|
|
};
|
|
var loginText = new TextField ("") {
|
|
X = Pos.Right (password),
|
|
Y = Pos.Top (login),
|
|
Width = 40
|
|
};
|
|
var passText = new TextField ("") {
|
|
Secret = true,
|
|
X = Pos.Left (loginText),
|
|
Y = Pos.Top (password),
|
|
Width = Dim.Width (loginText)
|
|
};
|
|
|
|
// Add some controls,
|
|
win.Add (
|
|
// The ones with my favorite layout system
|
|
login, password, loginText, passText,
|
|
|
|
// The ones laid out like an australopithecus, with absolute positions:
|
|
new CheckBox (3, 6, "Remember me"),
|
|
new RadioGroup (3, 8, new [] { "_Personal", "_Company" }),
|
|
new Button (3, 14, "Ok"),
|
|
new Button (10, 14, "Cancel"),
|
|
new Label (3, 18, "Press F9 or ESC plus 9 to activate the menubar"));
|
|
|
|
Application.Run ();
|
|
}
|
|
}
|
|
```
|
|
|
|
Alternatively, you can encapsulate the app behavior in a new `Window`-derived class, say `App.cs` containing the code above, and simplify your `Main` method to:
|
|
|
|
```csharp
|
|
using Terminal.Gui;
|
|
|
|
class Demo {
|
|
static void Main ()
|
|
{
|
|
Application.Run<App> ();
|
|
}
|
|
}
|
|
```
|
|
|
|
The example above shows how to add views using both styles of layout supported by **Terminal.Gui**: **Absolute layout** and **[Computed layout](https://migueldeicaza.github.io/gui.cs/articles/overview.html#layout)**.
|
|
|

## History
|
|
|
|
This is an updated version of [gui.cs](http://tirania.org/blog/archive/2007/Apr-16.html) that Miguel wrote for [mono-curses](https://github.com/mono/mono-curses) in 2007.
|
|
|
|
The original **gui.cs** was a UI toolkit in a single file and tied to curses. This version tries to be console-agnostic and instead of having a container/widget model, only uses Views (which can contain subviews) and changes the rendering model to rely on damage regions instead of burdening each view with the details.
|
|
|
|
Release history can be found in the [Terminal.Gui.csproj](https://github.com/migueldeicaza/gui.cs/blob/master/Terminal.Gui/Terminal.Gui.csproj) file.
