Output Toolbar Contribution

File: custom-ui/src/frontend/output-toolbar-contribution.ts

Overview

Customises Theia's output view to keep it always available and stable:

• Output widget starts in a locked state.
• Output tab is not closeable.
• Toolbar buttons for clear/lock/unlock are removed.

Functions

initOutputContribution

export const initOutputContribution = ({
  bind,
  rebind,
}: {
  bind: interfaces.Bind;
  rebind: interfaces.Rebind;
}): void

InversifyJS wiring entry point.

Bindings

Action	From	To

rebind	TheiaOutputToolbarContribution	OutputToolbarContribution
rebind	TheiaOutputWidget	OutputWidget (singleton)

Classes

OutputWidget

@injectable()
export class OutputWidget extends TheiaOutputWidget

Custom State

protected _state: TheiaOutputWidget.State = { locked: true };

Starts with output locked.

Constructor

Calls super() then sets:

this.title.closable = false;

This prevents users from closing the Output tab.

---

OutputToolbarContribution

@injectable()
export class OutputToolbarContribution extends TheiaOutputToolbarContribution

registerToolbarItems(toolbarRegistry: TabBarToolbarRegistry): void

Calls super.registerToolbarItems(toolbarRegistry) first, then unregisters:

Toolbar item id	Command
OutputCommands.CLEAR__WIDGET.id	Clear output
OutputCommands.LOCK__WIDGET.id	Lock output
OutputCommands.UNLOCK__WIDGET.id	Unlock output

Result: output toolbar is simplified and immutable for end users.
