Bug 49370 – [Qt] linkDelegationPolicy and linkClicked signal to the declarative WebView

• Component: New Bugs
• Status: RESOLVED INVALID

[Henry Haverinen]

The QML WebView does not support the link delegation policy or linkClicked signal that are supported in QWebView (see http://doc.qt.nokia.com/4.7/qwebview.html#linkClicked). This feature would be useful for Qt Quick developers too.

Closing until you give use cases for this.

In general, this signal is too limited for the conventientional use cases. Users generally end up using QWebPage::acceptNavigationRequest() instead of linkClicked.

Example test app that requires the linkClicked signals and the linkDelegationPolicy to be set

The linkClicked signal is important in cases where the QML programmer wants to have more control on how the WebView behaves. Here's an example:

"I want to create a new WebView with the link URL from link clicked so that I can use a QML Transition to show the user that he/she has navigated away from the application content into a 3rd party website".

Using onUrlChanged and then stopping seems to cause the WebView to start loading, which seems to cause the webView to blank. Also, doing transitions while WebView is loading content can cause choppy transitions.

In my opinion the example attached illustrates my point on why we should not have this. :)

But I don't care that much about the issue so I can reopen this. Feel free to provide a patch for API reviews.

this functionality is valuable in 2 use case:

1 The application does not want to open the link in this instances of webview (that is embedded in the application), but wants to call xdg_open. It cannot do that with the currently supported QML WebView signals.

2. The link is not an http link, but instead some other scheme that WebView or the browser engine does not know about. With link delegation and a linkClicked signal, the application can handle this case easily.
