I have made a user script to integrate http://code.woboq.org/qt5/ with gerrit.

With that script, you can just click on a function in the code on gerrit and 
it will lookup in the code.woboq.org database and show the signature in a 
tooltip and links to code.woboq.org. (It shows a disambiguation popup if there 
are several possibilities.)
It also makes the filename in the header of the diff clickable to the 
corresponding file on code.woboq.org

Look at this screenshot: http://i.imgur.com/Q3a2ixz.png 
When you see the signature you can see the return type. And had 'auto' been 
used there, we would have known it's a QUrl. 

This does not work for all functions, but should already be of a great help 
when reviewing.

The user script is there: 
   https://code.woboq.org/qt-gerrit.user.js
You can use it with the Greasmonkey extension on Firefox or the Tampermonkey 
extension on Chrome, or whatever equivalent extension for your browser.

If qt-project's admins think it's a good idea they could enable it by default.

Hi,

I can see how people keep trying to integrate changes into qtdeclarative's 5.6 
branch. Until https://codereview.qt-project.org/#/c/143824/ lands, all those 
attempts of integrating changes are going to fail, unfortunately :)

[Development] QML Memory leak.

[Polepalli, Ravikiran]

Hi All,

I'm working on a project and I'm affected by Memory leak in QML.
https://bugreports.qt.io/browse/QTBUG-42055
https://bugreports.qt.io/browse/QTBUG-28712

I tried to run the test application(qml available in ticket) on a target board.
In the application QML Object is created and destroyed for every 100ms. 
Application ran for 2 days.

Here are observations:

-Overall memory increased 1MB for every ~90mins.

-Captured memory usage for every 10 mins(through pmap -x $pid).

-Memory map is not changing except number of "[anon]" allocated memory 
blocks was growing constantly for every ~90mins.

-At end of test run approximately 82 blocks were seen.

-
Could anyone help me understand where memory leak could possibly be?
I would like to know if the memory leak is fixed. Any patch/solution available 
to fix this issue?
Any help would be great.

Thanks and regards,
Ravikiran.

Thanks, didn't realise. Thought it was a random failure.

Cheers,

True. You can use Qt Designer's 'Widget Promotion' though:

Re: [Development] New Qt5.6 Beta snapshot available

[anton]

So if I understand right,
in a Qt Widgets Application I can no more embed 
a Html/Browser component anymore.

I have to use QML instaed since WebView seems to be
QML only (if I understood the docs).

Anton

PS: By the way: where can I see the roadmap of Qt?

You can use QtWebEngine instead which is the successor of QtWebKit,
and based on Chromium:
