General and Desktop

Agree: put this good idea in a wiki page and notify to us. Remember to add the tags to simplify search finding.

yes, it work well after copied the *.dylib to Myapp.app/Context/MacOS

Any other clever ways of scaling all of the widgets in an Application. We've gotten comments from our users that some of the widgets are hard to read on their monitors and they'd like a zoom feature. I don't think converting our entire application to use QGraphicsScene is viable at this point. I could override the font size in the stylesheet but that only scales the font and only the widgets that have text will increase in size. Thanks for the feedback!

That's a great idea and is working wonderfully. I opted for this approach in the end, however I did manage to get it working the other way as well, silly me did not notice the isSliderDown() call for QScrollBar's. One caveat to your approach is that I had to set a flag to determine if this was the first time I am appending text in which case I move the scroll bar to the maximum position. Thanks!

Thanks, this is the piece of information I was seeking for!

We do not support showing pdf files inside Assistant, we basically dump them out of the compressed help file and use the corresponding desktop application to show it. [/quote] Ah, yes, that's what I thought. I was a bit confused by posts like this, though: http://stackoverflow.com/questions/6947172/how-to-link-to-a-pdf-file-in-qt-assistant [quote author="Lukas Geyer" date="1316504075"] [quote author="toralf" date="1316443967"]I've actually packaged a couple of PDFs and one of my collections, and seem to remember having been able to view them in the past, but I could be wrong...[/quote] Looks like you aren't. If it has worked for you but it doesn't anymore you should file a bug-report.[/quote] https://bugreports.qt.nokia.com/browse/QTBUG-21559 ;-) I've found that as a workaround, PDFs may be packaged with a non-standard filename suffix - I've used ".pdf_". Qt Assistant will then fail to understand that the files have PDF format and will thus not assume they may be viewed internally. The desktop support routine that is called as a consequence, to open the files with an external application, will on the other hand still recognise them (based on content, I suppose) - at least on my setup.

May be you can get "Pie chart example":http://doc.qt.nokia.com/4.7/itemviews-chart.html and remake it for bar.

Well, answering myself, but the making a html from generateDocumentation().toStdString() was useful. It works partially. I can call functions, but can't get results back from them. I can get results back from int&, but can't get any values back from QString&. I've also used both flavors of dynamicCall().

I use debian with gnome.

There was a bug, and I introduced it. Qt is alright ;) . Consider this solved.

Hi Lukas I have added those resource files while creating GUI in QtDesigner. I am not adding those through code. How to check wether they are part of application or not?

dcortesi: You're correct. I didn't think about \1s in the replacement string.

Just in case you're interested, I've gotten a bit further. New thread posted here: http://developer.qt.nokia.com/forums/viewthread/9957/

You can use this: @ typedef QVector< short > SubContainer; const int size = 100; QVector< SubContainer > vv( size, SubContainer( size ) ); @ As you said you can access elements with @vv.at( x ).at( y )@ or with @vv[ x ][ y ]@

@Volker: Thanks you, very very useful. I am just working with a multilanguage aplication including Turkis.

No problem, just happy to be able to help out!

Thanks, I ended up doing something similar. I'm surprised there are not direct api calls to help with this.

[quote author="fluca1978" date="1316606616"] I believe it is a bad idea to hard code '/' anyway, you should use Qdir::separator instead.[/quote] No, hard coding '/' is indeed the proper way. From the QDir::separator() documentation: bq. You do not need to use this function to build file paths. If you always use "/", Qt will translate your paths to conform to the underlying operating system. If you want to display paths to the user using their operating system's separator use toNativeSeparators().

Many thanks, this is really useful. I have a lot of book on C++ but this maybe a idea. I am approaching to develop some GUI stuff in a multiplatform environment :) Cheers, Enrico
