<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"> Hi,</p>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; "> </p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"> Jan Grulich is working on implementing settings support in QtNetworkManager [1]. His code is in the settings branch and he asked me to take a look at the code. I am sending this e-mail to everybody because some of the issues spotted below can be usefull for the other people working on Plasma NM/QtNetworkManager/QtModemManager. Here are my findings/comments:</p>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; "> </p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">. Do not to initialize QString class members with QString(), this saves a QString() contructor call. Also, if you ever need to empty a QString use</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">QString::clear() instead of assigning QString() to it for the same reason.</p>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; "> </p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">. NetworkManager::Device::availableConnections() allocate new objects without parent and without warning the user of that method that they should deallocate the memory used. Preferrably you should use a cache mechanism like the one used by NetworkManager::networkInterfaces() to prevent this memory leak.</p>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; "> </p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">. Use qobject_cast instead of dynamic_cast with QObjects.</p>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; "> </p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">. In examples/createconnection/main.cpp you can use 'result.ToLower() == "yes"' instead of those three comparisons with "yes", "YES" and "Yes". You could also add more comments describing in details what the examples do. I also see that you use Settings::WirelessSetting::setSsid(ssid.toAscii()) there. Is the 'toAscii()' part required for this to work perperly? If so then that should be added to the setSsid() API doc (in settings/802-11-wireless.h). By the way, all class methods in settings directory lack API doc comments, I know, that is not your fault since you copied the classes from Plasma NM. Yet that is one thing we need to fix before the first release.</p>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; "> </p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">. in NetworkManager::Settings::WirelessSecuritySetting::fromMap() I think you should add a 'else { nmDebug() << "Unhandled item comment"; }' for each of the if's in there. That would help us detect when NetworkManager adds new possible values in their API.</p>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; "> </p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">. also in NetworkManager::Settings::WirelessSecuritySetting::fromMap() you insert some QStringList without checking if they are not empty. Usually NetworkManager refuses settings with empty values, which is the case here. You can add some Q_ASSERT() to check for that. This way the check will only be add to the final binary if Qt is compiled with debug enabled. </p>

<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">. Code style:</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"> - use 'foo &bar' instead of 'foo& bar' or 'foo & bar'.</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"> - do not add empty lines without any purpose.</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"> - start comments with capital case and with a period in the end. Also add one space between // and the start of the comment.</p>
<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"> - you can use astyle command to do most of those changes. See</p>

<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">. Commit messages should be "git-formatted": one short summary in the first line, followed by an empty line, and then a longer explanation of why the commit has been made and what it does. Yes, I know, I also need starting doing that myself.</p>

<p style=" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;">. you should also run krazy2 to detect any other possible issueѕ I have not spotted: http://techbase.kde.org/Development/Tutorials/Code_Checking. Some of the issued reported by krazy2 are KDE specific and does not apply to libnm-qt, which is Qt only library.</p>
