QWebView disables text selection when right-clicking

Question

Right-clicking on any text on a web page viewed with QWebView on Windows selects the word under the cursor. I want to disable this behavior, but cannot find the link in the docs.

Answer 1

This preference looks deep in Webkit (an engine that includes QWebView and Google Chrome among many others). There is a QtWebkitRelease20 error (version released with Qt 4.7.x ) - I think that’s why the behavior you want is visible in Chrome , but not Qt . There is another upcoming QtWebkitRelease22 branch that will be included as part of Qt 4.8 . I think that the change you will then be implemented in this version.

So, your options, as I see them, are as follows:

• To bite a bullet and upgrade to Qt 4.8.0 RC
• To wait for a stable version of Qt 4.8 and come up with a workaround:
  • Will this work for you to completely disable the context menu? QWidget::setContextMenuPolicy(Qt::NoContextMenu) will do the job, if so.
  • You can connect to QWebView::selectionChanged() signal , and then use findText("") to deselect.

We can use the JavaScript function to disable text selection in several browsers, following

 <script type="text/javascript"> function disableSelection(target){ if (typeof target.onselectstart!="undefined") //For IE target.onselectstart=function(){return false} else if (typeof target.style.MozUserSelect!="undefined") //For Firefox target.style.MozUserSelect="none" else //All other route (For Opera) target.onmousedown=function(){return false} target.style.cursor = "default" } </script> 

Call this function

 <script type="text/javascript"> disableSelection(document.body) </script>
