+    \qmltype CustomTouchHandle
+    \inqmlmodule QtWebEngine
+    \since QtWebEngine 6.4
+
+    \brief Data class for representing the touch handle QML delegate.
+
+    The handle's position, opacity, and visibility are updated automatically.
+    The delegate should be a QML Item or any QML type which inherits it.
+
+    The following code uses a custom touch handle delegate:
+
+    \code
+    WebEngineView {
+    // ...
+        touchHandleDelegate: Rectangle {
+            color: "red"
+        }
+        // ...
+    }
+    \endcode
+
+    \note The bounding box which propagates the touch event is provided by
+    Chromium and the text selection can be moved even if there is no handle drawn.
