# Read only mode: disable annotations, editing & user interactions

Enable or disable various PDF editing features with ease using this comprehensive guide. Learn how to selectively enable or disable annotation creation, form filling, signing, and more. Optimize your

Actions such as annotation creation, editing, form filling, signing, and link following etc. are enabled by default. It is possible to selectively enable parts of such functionality as well as completely disable all interactive features.

## Disable PDF editing

To disable PDF editing, such as adding annotations, filling form fields or signing, use [`ToolManager.setReadOnly(boolean)`](https://sdk.apryse.com/api/android/javadoc/reference/com/pdftron/pdf/tools/ToolManager.html#setReadOnly\(boolean\)).

{% tabs %}
{% tab title="Java" %}
{% code lineNumbers="true" %}

```java
toolManager.setReadOnly(true);
```

{% endcode %}
{% endtab %}

{% tab title="Kotlin" %}
{% code lineNumbers="true" %}

```kotlin
toolManager.isReadOnly = true
```

{% endcode %}
{% endtab %}
{% endtabs %}

where `toolManager` is the instance of `ToolManager`.

## Disable all user interaction

To disable all user interaction on `PDFViewCtrl`, such as selecting text, selecting annotations, do not associate a `ToolManager` with a `PDFViewCtrl`. For example, do not use `ToolManagerBuilder` to create a `ToolManager` object.

## Disable annotation creation and editing

To hide all UI widgets that are associated with creation and editing of a particular annotation type, see: [Disable annotation creation and editing ](/android/annotation/disable-annot-create-edit.md).

## Disable other functionality

To disable functionality that is not directly tied to annotations, see: [Disable functionality ](/android/annotation/disable-annot-create-edit.md#disable-functionality).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.apryse.com/android/annotation/pdf-read-only.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
