Title: The Broadway windowing system

|
|
Slug: broadway
|

|
## Using GTK with Broadway
|
||
|
|
|
||
|
|
The GDK Broadway backend provides support for displaying GTK applications in
|
||
|
|
a web browser, using HTML5 and web sockets.
|
||
|
|
|
||
|
|
To run your application in this way, first run the broadway server,
|
||
|
|
`gtk-broadwayd`, that ships with GTK:
|
||
|
|
|
||
|
|
```
|
||
|
|
gtk4-broadwayd :5
|
||
|
|
```
|
||
|
|
|
||
|
|
The server expects the colon-prefixed display number as a commandline argument.
|
||
|
|
|
||
|
|
Then point your web browser at `http://127.0.0.1:8085`.
|
||
|
|
|
||
|
|
Once the Broadway server is running, you can start your applications like
|
||
|
|
this:
|
||
|
|
|
||
|
|
```
|
||
|
|
GDK_BACKEND=broadway BROADWAY_DISPLAY=:5 gtk4-demo
|
||
|
|
```
|
||
|
|
|
||
|
|
Multiple applications can be presented in the same web browser window.
|
||
|
|
|
||
|
|
## Broadway-specific environment variables
|
||
|
|
|
||
|
|
### `BROADWAY_DISPLAY`
|
||
|
|
|
||
|
|
Specifies the Broadway display number. The default display is 0.
|
||
|
|
|
||
|
|
The display number determines the port to use when connecting to a Broadway
|
||
|
|
application via the following formula:
|
||
|
|
|
||
|
|
```
|
||
|
|
port = 8080 + display
|
||
|
|
```
