Hm as long as QThread isn't owned by workObject it should be okay for the workObject to launch its thread and move itself there. I personally like it more when a third instance controls the thread and workObject creation and brings both together. This is helpful e.g. when you want to take the threads from a thread pool and feels slightly cleaner, because it keeps the achtual worker and the "low-level" thread handling separated.

I think you do not need a timer. see "MouseMoveEvent":http://qt-project.org/doc/qt-4.8/qwidget.html#mouseMoveEvent and "setMouseTracking":http://qt-project.org/doc/qt-4.8/qwidget.html#mouseTracking-prop

I tried qxoz's suggestion of adding the <normaloff> and <selectedon> tags but with this, no icon is generated. Here's how my UI file looks like: I even added a <normalon> tag just in case and that did not help either.... @@ <widget class="LedButton" name="m_Standby_btn" > <property name="icon"> <iconset resource="VSMgui.qrc"> <normalon>:/images/images/whiteCircle_nt.png</normalon> <normaloff>:/images/images/whiteCircle_nt.png</normaloff> <selectedon>:/images/images/blueCircle_nt.png</selectedon> </iconset> </property> <property name="text" > <string>Standby</string> </property> <property name="visible"> <bool>true</bool> </property> </widget> @@

Well why don't you just look yourself? ;) http://qt.gitorious.org/qt-solutions/qt-solutions/blobs/master/qtservice/src/qtservice.h says BSD License, so it's free software. When I remember correctly LGPL is available, too, but BSD is more permissive anyway.

Please be sure and edit your original post and add [Solved] to the title. Thanks!

I'm having the same problem on a windows 7 64 bit VM machine. I can play some mp3's but not all. I downloaded an mp3 from amazon that did not work. Windows media player plays the mp3 fine. Not using phonon and trying to create the graph myself it did not work either.

thx

Solved, I had bad declaration of object PostgreConn. I fix it: @qDebug() << "PostgreSQL Inicialization starts"; PostgreConn *db; db = new PostgreConn("192.168.1.30", "5432", "postgres", "pass", "test"); db->close();@

Well the best that could happen to me was that I could 'store' the helpcollectionfile (qhc) in a resourcefile (qrc). So it can easily be distributed. Cause this application is going to be used by hundreds, maybe thousands of users. And then it would be much easier to get it in just one executable. My colleague is coming back next week, i'll ask him if he has a decent solution. But thanks for the help anyway :) Great forums here

Qt Creator has a resource editor you might use, but you can also hand-craft resource files. It is a simple XML format. This is a sample from the documentation: @ <!DOCTYPE RCC><RCC version="1.0"> <qresource> <file>images/copy.png</file> <file>images/cut.png</file> <file>images/new.png</file> <file>images/open.png</file> <file>images/paste.png</file> <file>images/save.png</file> </qresource> </RCC> @ However, just to try if it works with images, you can also just leave them on the file system and provide the correct path. If it works, you can stick the images in a resource and compile the images into your application that way. Note that I am not sure that this is your solution.

Hello, I used tree to show my data in tree view in my tabs, which existed in main window. I think I may need a parser to pares my data, which are on the newly created file, also using setupModelData method in treeModel.cpp, and add it to my tree model. I am still worḱing on it.

the forward slash / has no special meaning in regular expressions. @QRegExp rx("([a-zA-Z]:[\\/]|[\\/]{2})");@ works for both backward and forward slashes. (Note I've removed the whitespace character from the drive letter) But beware, you should also allow unix paths like "/home/dermanu", so possibly group "[a-zA-Z]:" together and make it optional by appending a "?" character

Hi, I think sync() will write to file only if you used QSettings::setValue(). Reading values does not change file, so sync() does not need to write it.

I also met a problem in using phonon on mac, but it came up after I quit the QT example app(QTmediaplayer.app). Did you met the problem likes me?

It's OK now.Thank you

[quote author="jstaniek" date="1336511641"]Hi, Have a look at Predicate lib which has SQLite3 plugin: http://community.kde.org/Predicate It's Qt-only, LGPL, and unlike QtSQL it 'knows' how to create database and then new tables (has a Qt/C++ API for that). No need to pass SQL at all (but it can be if you wish). I am preparing this lib as a next get backend for Kexi and similar complex apps. The only downside - it's not yet released and its API isn't frozen, so you'd need a copy of it.[/quote] Thanks, this sounds like exactly what I have been looking for. Unfortunatly I'd prefer to avoid any dependencies (except Qt itself) as much as possible. I just hoped that there simply is a qt-api for my case that I simply couldn't find. I will accept that there is no api by qt, so I will do it by hand with SQL-commands.

[quote author="glararan" date="1336503116"]I add it to code...nothing changed EDIT:SOLVED[/quote] Hi, You need to EDIT your first post and append SOLVED if you got the answer. If not then you can provide your code so that we can figure out the above behavior of the progress bar. As it has already been explained above that stylesheets mostly deals with the look and feel of the component. Thanks :)
