[Development] New QTextDocument feature: CSS-style table cell border formatting
Hi list, the existing QTextDocument table style options are rather lackluster. It's basically "ugly grid" (resembling ancient 1998's html tables) or "no grid". As we needed some more flexibility we've implemented a subset of the CSS table cell border formatting including a border-collapse mode. This includes correct pagination (border line continuation) and repeated header rows suitable for printing. We've also added support for a subset of the CSS border styles (limited to TD elements) in the HTML importer and exporter so that it's possible to use Qt's TextEdit example for trying the new functionality. I'd like to invite anyone interested to have a look at this change request: https://codereview.qt-project.org/#/c/126950/ Any feedback and hints on how to add reasonable auto tests will be appreciated.

How do we do it with MSVC? What's the equivalent to -fkeep-inline-functions? And if it's that easy for you to create it, I think you should create that yourself in your project. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center ___ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development

When I tracked down the failures, I did find out that it was related to the original QString being reallocated, so the QStringRef had a dangling reference. But I don't remember more details. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center ___ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development

I had that too, but it's a different bug. It happens on the same thread that called exit(). libQt5Sql.so calls plugin code at static dtor time, at which point the plugin was already unloaded.

( plugin calling libQt5Sql is fine, the other way is not). 3) If you have to do 2), then don't call exit() :) Regards, -- Sérgio Martins | sergio.mart...@kdab.com | Software Engineer Klarälvdalens Datakonsult AB, a KDAB Group company Tel: Sweden (HQ) +46-563-540090, USA +1-866-777-KDAB(5322) KDAB - The Qt Experts ___ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
