# Falkon QML Tutorial - 9. Falkon windows

Hello, in this chapter I will show you how to work with windows.

## Access windows api
The windows API can be accessed through code.
```qml
Falkon.Windows
```
More information can be found in the
[documentation](http://falkon.sgorava.xyz/docs/class_qml_windows.html).

### Get windows
To get to the windows we can use three methods `get(windowId)`,
`getCurrent()` and `getAll()`. These methods return a window or array of
windows of type `Window` (see
[documentation](http://falkon.sgorava.xyz/docs/class_qml_window.html)
) which van be manipulated further.

Example:
```qml
/* Get a specific window with known ID */
var window = Falkon.Windows.get(0)

/* Get current window */
var currentWindow = Falkon.Windows.getCurrent()

/* Get all windows */
var allWindows = Falkon.Windows.getAll()
```

### Create a new window
To create a new window we have to supply it with URL and window type.  
The `type` is optional and by default the `NewWindow` will be used.

```qml
Falkon.Windows.create({
    url: 'https://falkon.org/'
    type: Falkon.Enums.WindowType.NewWindow
})
```

### Remove an existing window
To remove an existing window we need to first know its ID in current
session and than we can use the `remove` method.

```qml
Falkon.Windows.remove(WINDOW_ID)
```

### Available signals
#### created(Window)
Triggered when new window was created with the new window in parameter.

#### removed(Window)
Triggered when window was removed (closed) with the window as a
parameter.  
The `Window.id` property provided by this signal is `-1` and because of
this I recommend to use `window` itself as a backup identifier.

## Window properties
Each window has some properties which can be read, we can also get to
all tabs which belong to that window.

```qml
window.id
window.incognito
window.title
window.state
window.type
window.tabs
window.focussed
window.height
window.width
```

More detailed information can be found in the
[documentation](http://falkon.sgorava.xyz/docs/class_qml_window.html).

## Example
The example will create a sidebar in which will be a list of currently
open Falkon windows with information and buttons to create and remove
windows.
