@Joel-Bodenmann To elaborate on your answer: The boundingRect() must include every pixel that you intend to paint to in your own item's paint method. That includes e.g. pixels that are outside your item proper, but painted to due to a wide pen. (Calculating the correct boundingRect for items with wide cosmetic pens can be a real pain.)

Hi, Do you also have that with a default application ?

Hi, sorry for the late response. Had a lot on my plate lately. For now, the tables are still truncated but modifying the html, i've made it so that the new pages (where the tables get truncated) show the table headers using the css suggested by @CKurdu .

Now issue is resolved, you can move the issue to SOLVED state. Enjoy Qt Programming.

Hi, That's nothing Qt, you should check your project for something related to that folder.

@Robinsondesbois can you share your result? thanks

@filipdns I don't see you adopting it in your last code snippet...

@AaronKelsey said in How to set current widget from QWidget class: Unfortunately I have little experience with signals and slots I suggest to learn this core concept of Qt, see: http://doc.qt.io/qt-5/signalsandslots.html

@mrjj said in Zero as null pointer: C++11 is needed to have nullptr C++11 is also needed for Qt 5.12, so that requirement is guaranteed in this case :)

Did you try to use the QScrollArea ? If you can give more details with some code example or image will help the team to help.

I tried with some experiments to handle such huge data, A SQL stored procedure is implemented which accepts XML as input reads it and stores in a table variable and insert in a single shot of e.g 7000 inserts in 1 to 1.5 seconds. My Qt application bundles the data in xml format of required amount of entries controlled in application. The stats i can compare here the sequential query call takes around 15-20 seconds to store 7000 records, The same 7000 records takes only 1 to 1.5 seconds to store via XML-stored proc implementation.

to get macdeployqt to find the libs at a different place, add -libpath=<path> to the end of the command. i have NOT figured out how to get it to place the libs in to the SharedSupport folder, but they DO work inside the Frameworks folder, even though they're NOT frameworks. huh.

Hi adding to jonB the text() returns a QString and you can access each char with the at() function http://doc.qt.io/qt-5/qstring.html#at Make sure you check string length before using this functions as it will crash the app if you do not handle it with care.

Personally I just needed to link to CoreServices and SystemConfiguration. # Static builds require direct linking to macOS services QMAKE_LFLAGS += -F /System/Library/Frameworks/CoreServices.framework/ QMAKE_LFLAGS += -F /System/Library/Frameworks/SystemConfiguration.framework/ LIBS += -framework CoreServices LIBS += -framework SystemConfiguration Cheers.

@juaniyoalm Well good work then. :) Please mark as solved. You can always make new posts for new problems. and happy programming.

@mzimmers Ok super. Normally any updates do not include extra Qt versions. it only updates those already installed. in any case, good you got rid of them.

On *nix systems, you drop the lib prefix when linking to a library. Like for example libz -> it's -lz.

You should interleave the audio data as required by the number of channels.

@SGaist As usual from you, a very interesting link! I'm not sure it does the same sort of thing as I had mind (visualizing layouts & widgets [EDIT hang on, https://doc.qt.io/GammaRay/gammaray-widget-inspector.html might be closest to what I had in mind]), and I won't get code navigation because Python, but I must give it a look. When I have a minute --- it looks quite complex/impressive!
