### Programmatic Setup

Because of that, tool windows are normally disabled while building indexes unless the `ToolWindowFactory` implements [`DumbAware`](upsource:///platform/core-api/src/com/intellij/openapi/project/DumbAware.java).
For programmatic setup, parameter `canWorkInDumbMode` must be set to `true` in calls to `registerToolWindow()`.
As mentioned previously, tool windows can contain multiple tabs, or contents.
As mentioned previously, tool windows can contain multiple contents (tabs).
To manage the contents of a tool window, call [`ToolWindow.getContentManager()`](upsource:///platform/ide-core/src/com/intellij/openapi/wm/ToolWindow.java).
To add a tab (content), first create it by calling [`ContentManager.getFactory().createContent()`](upsource:///platform/ide-core/src/com/intellij/ui/content/ContentManager.java), and then to add it to the tool window using [`ContentManager.addContent()`](upsource:///platform/ide-core/src/com/intellij/ui/content/ContentManager.java).

Use `Content.setDisposer()` to register associated `Disposable` (see [](disposers.md)).
### Closing Tabs
A plugin can control whether the user is allowed to close tabs either globally or on a per-tab basis.
A plugin can control whether the user is allowed to close tabs either globally or on a per-content basis.
The former is done by passing the `canCloseContents` parameter to the `registerToolWindow()` function, or by specifying `canCloseContents="true"` in <path>plugin.xml</path>.
The default value is `false`; calling `setClosable(true)` on `ContentManager` content will be ignored unless `canCloseContents` is explicitly set.
If closing tabs is enabled in general, a plugin can disable closing of specific tabs by calling [`Content.setCloseable(false)`](upsource:///platform/ide-core/src/com/intellij/ui/content/Content.java).
