General and Desktop

To add to @SGaist: In my company we build the same code in 3 platform Windows / Visual C++ Linux / g++ OSX / clang Usually Visual C++ is the one less conform to the standard

You're welcome ! One thing you could do is create a feature request (but first check if somebody already asked for it) to add an API that allows to change that symbol

Hi, don't know about PyQtX but for a vanilla standalone Qt app on the Mac, the Qt platform plugin usually resides in @executable_path/../PlugIns/platforms/libqcocoa.dylib Also note that the Qt plugins are not loaded using the PATH mechanism (i.e. adding a path to the .dylib isn't needed) instead Qt looks in the @executable_path/../Resources/qt.conf file for where to find libqcocoa.dylib.

Ok, no problem! Happy programming

@mcosta this is exactly what i need ^^ thank you !! ^^

@mcosta yes i also prefer using custom widget , thanks for your help ^^

Hi, try to pass -ExecutionPolicy Unrestricted as parameter.

thank you it is working. it will save me a lot of work

I solved the problem, the working code is: QVariant TreeModel::headerData(int section, Qt::Orientation orientation, int role) const { if (role != Qt::DisplayRole) return QVariant(); return "HeaderData !!!"; } See these topics: QTreeView not displaying data QTreeView not showing header

Good idea, thanks! ...but doesn't work.

@Asperamanca Wow, thank you, sounds great (difficult but great). I'll think about it and try to implement. And if it won't be too complicated, I'll definitely use it, it could be exactly what I'm looking for. Thanks again.

Hi and welcome to devnet, WARNING: I'm not a lawyer AFAIK, the modules you're listing here are part of the Enterprise/Professional editions and not available with the community edition (and in not even provided in sources).

What was the problem ?

@JKSH someone helped me solve the issue, thanks anyway! http://www.riverbankcomputing.com/pipermail/pyqt/2015-March/035717.html

Thanks alot , it solved problems.

Wouldn't it be simpler also for debugging to build both ? In any case, since you have it working now, please mark the thread as solved so other forum users may know a solution has been found :)

yes i have, w.setStyleSheet("background-image:url(:/file/left.png); background-repeat: no-repeat"); It only fills up PC monitor width, thus i add setFixedWidth to set the width i want w.setFixedWidth(1366); On my laptop it work perfectly, but when i cross-compile and test it on the ARM target. The mainwindow is expanded over the whole screen. Is there any workaround?
