That's right ! These instructions are just added considering the application calling my Qt Dll are not "Qt native" and there is no QApplication instance yet. In the present usage qApp is not NULL (instance on app side) and anyway the following instructions won't be executed on Dll side : @ if (pApp){ pApp->quit(); delete pApp; } @

Thanks to point me to QCustomPlot Code_ReaQtor. It seems very interesting. :) In the meanwhile, I've tried to recompile qwt for my embedded system but still had trouble. However, it seems that the problem is only related to a linking issue with the qwt and the cross-compiling toolchain used is not directly involved. I'll investigate the issue further these days. As a next step, I'm going to give QCustomPlot a try. Thanks again.

Ahh!!!Ok I didn't know it :S. Sorry. I know something new now :)

[quote author="vsthakur1" date="1352770236"] How to deal with ")" character in the URL , so that is is not broken ? [/quote] Have you tried adding backslash ("") before it? e.g. ")". There are instances that we need to add "" when dealing with special characters.

I'm not quite sure what you are trying to do, but QTest can emulate user input (like Mouse).

You seem to be missing something in your typedef. I'll assume this is something like @typedef SomeGiantTypeThatIDontWantToRetypeOrWhatever SmartPointer;@ qRegisterMetaType takes a string name of your class e.g. @qRegisterMetaTypeexample::SmartPointer("SmartPointer")@ You can call it wherever just as long as your typedef is visible there and before you use it for connecting or access its metadata. Also, make sure you use Q_DECLARE_METATYPE outside of your example namespace.

I'm trying to try again, thanks.

I also can not use any QGraphicsEffects on OS X without it crashing. It runs just fine if I don't set the QGraphicsEffect on the QPushButton, but if I do, it crashes as soon as it tries to draw/paint.

Hi, ~CanisMajorWuff! Welcome to Developer Network! Sorry, but it's better to write Qt instead of QT. Because QT is QuickTime, not Qt.

That's a shame. I guess we'll have to stick with the old engine for now. I've dug around trying to figure out how add slot/signal support but that is entirely non-trivial.

100% True... I Will think about it next time.. :-) Thanks & Regards

If I install the MinGW 4.4 I will not need to compile all libs?!

[quote author="Lukas Geyer" date="1352735892"]I would start with setting the Qt:WindowStaysOnBottomHint window flag. I'm not quite sure on how to hide it from the Unity bar, but usually a hidden parent window does the trick.[/quote] Well that did make the window stay in the background, Thanks! Now I just gotta figure out how to do the rest of the things.

Thanks for the info. That's good news.

Aah thank you both.

Hi, Thx for the replies! Will try to implement the QStandardItemModel at first. It seems the most easy way to go. Thx again!

Yes, you can create activex and use it on Qt and vice versa. take a look at examples for ActiveQt to understand how to take QObject drived classes into .Net and other environments. http://qt-project.org/doc/qt-4.8/activeqt-dotnet.html http://qt-project.org/doc/qt-4.8/activeqt-wrapper.html
