[PyQt] How to customize link click behavier of QWebEngine?

[Jones, Bryan]

Here's what I do -- override the acceptNavigationRequest method in a
derived class.

class QWebEnginePageExtLink(QWebEnginePage):

def acceptNavigationRequest(self, url, navigationType, isMainFrame):

# Only open a link externally if the user clicked on it.

#

# The following HTML produces navigationType == 0 (link clicked) and

# isMainFrame == False. (This makes no sense to me). So, only open main
frame clicks in an external browser.

## <a class="reference external image-reference" href="
https://pypi.python.org/pypi/PyInstaller"><object data="
https://img.shields.io/pypi/v/PyInstaller.svg" type="image/svg+xml">
https://img.shields.io/pypi/v/PyInstaller.svg</object></a>

if (navigationType == QWebEnginePage.NavigationTypeLinkClicked and
isMainFrame):

res = QDesktopServices.openUrl(url)

if res:

core.mainWindow().statusBar().showMessage("{} opened in a
browser".format(url.toString()), 2000)

else:

core.mainWindow().statusBar().showMessage("Failed to open
{}".format(url.toString()), 2000)


# Tell the built-in browser not to handle this.

return False

else:

# Handle this in the built-in browser.

return True
