Virtual Keyboard & Text Input Focus

Quest 3D WebView features an automated text focus bridge that makes integrating 3D VR keyboards seamless.

1. Automatic Text Input Focus Detection

Whenever a user clicks or focuses an interactive HTML element on the webpage:

• <input type="text">, <input type="password">, <input type="search">
• <textarea>
• Elements with contenteditable="true"

The plugin automatically fires the OnTextInputFocusChanged event delegate:

[ QuestWebViewComponent ] ──► ( Event OnTextInputFocusChanged )
                                       ├── WebView: UQuestWebViewComponent*
                                       └── bFocused: Boolean (True/False)

You can use bFocused to automatically show, hide, or dock your 3D VR Keyboard (e.g. WBP_VirtualKeyboard) in front of the active screen!

2. Inserting Text & Dispatching Keystrokes

SendText(Text)

Inserts the provided string directly at the current cursor position in the focused HTML input.

• Best used for: Character typing buttons ('A', 'B', '1', '@'), voice-to-text dictation strings, or pasting URLs.
