# Status Bar Sample
|
|
|
|
This is a sample extension that adds a status bar entry showing the current number of selected lines.
|
|
|
|
It is not intended as a product quality extension.
|
|
|
|
- Open a text editor
|
|
- Select some lines
|
|
- See the number of selected lines in the status bar
|
|
|
|
|
|
|
|
# How it works, what it shows?
|
|
|
|
- The extension implements and registers a [`StatusBarItem`](http://code.visualstudio.com/docs/extensionAPI/vscode-api#StatusBarItem) to show the number of selected lines.
|
|
- The extension listens to [`events`](http://code.visualstudio.com/docs/extensionAPI/vscode-api#_window) when the active text editor changes to keep the number of selected lines up to date.
|
|
- Registers a command via `package.json` that will show the number of selected lines as message
|
