[Viewer Plugin] Get selected text on right click.

jverrone3 · 03-27-2015, 12:37 PM

The Calibre ebook viewer has some functionality built into it that I would like to implement with a plugin.

The goal is to have something similar to the "Search Google for [selected text]" when you right click. Instead of the action opening an internet browser, I would like to create a modal pop up that contains more information based on the given text.

Ideally I would also like to create a button in the toolbar that would hold the same functionality.

I see the customize_ui(ui) and customize_context_menu(menu, event, hit_test_result) methods in the ViewerPlugin, but I am stuck on how to actually get the selected text from these parameters and connect a click event to these items.

hit_test_result is a QWebHitTestResult. You can use the enclosingFrame().page() method to get a QWebPage and then use selectedText() on the QWebPage.

Alternately, in customize_ui() store a reference to the ui object in your plugin. The do self.ui_ref.document to get a reference to the QWebView.
