Description Dinu Jacob 2010-10-27 10:42:07 PDT
1. Open a launcher window
2. Type in google.com
3. Select Develop->QGraphicsView-> Toggle use of QGraphicsView

Result: View changed but 'google.com' is removed from the url text box.

Related use case: After loading a page, and the user enters a new url and then changes to graphicsview, old page is reloaded and not the new url entered by the user.

First off, this behavior sounds a bit strange behavior to me, shouldn't we load what's currently loaded, and simply preserve the text in the location edit?

Extra space after =

Name should be "addressUrl"

As the page was being loaded when the view is toggled, I used the user input rather than the page to avoid having to request the page to be loaded again. If the current page is loaded and the user input is preserved, it would be confusing as there is indication of a page being loaded but that doesn't match the user input.

In your code below (impl of addressUrl) you return a string, which you convert into an QUrl here.

Here you convert it into a string again!

This is what I mean!

load is an overloaded function. I want the one that takes in a string so that the appropriate scheme is added which is done by the version that takes in a string. I convert it into QUrl to check whether it is valid before actually loading it. What can I do differently?

We have a method that handles this QUrl::fromUserInput(). I'm pretty sure we are already using this in the test browser. At the end, WebKit expects a QUrl.

I can not reproduce it on trunk. Are you running 2.1 branch?

Yes, that is what MainWindow::load(const QString& url) is using too but in addition to that it it also converts relative file path to absolute file path and I am just continuing to use that.

So to use the overloaded load method that takes in a QString and to check whether the url is valid before calling load, I need the conversion from Url to String again.

Patch with review comment changes

Changed logic to avoid converting to QString->QUrl->QString. Also, caling MainWindow::load instead of page()->mainFrame()->load to set the input field value that would otherwise be removed when toggling view (and set only later)

Before reviewing, with this patch we would end up with the following behavior:

1) load qttestbrowser
2) type 'google.com' in the urlbar
(do NOT press ENTER or any other action that triggers loading)
3) switch to graphicsview mode.
result: google.com is loaded.

do we want this, or we want to keep the loaded current URL (about:blank in this case) and keep the current entered content in the urlbar ('google.com' in this case)?

I used the entered url to avoid doing another load (if a page has already been loaded, it will re-load the page and then the user has to press ENTER key to load the new page again). Also, the url displayed will not be consistent with the page loaded.
