That's what I will end up having to do, but one should consider the potential size of an object which may or may not be in memory. If the object is memory mapped to disk one could have to parse many gigs to obtain something that is less than twenty bytes in from the end. The proposed solution works ...

I know nothing about Object Pascal. What I can tell you about is C++, at least a bit. inline void copyPWideStringToQString(PWideString ps, QString &qs) { qs.setUtf16((ushort *)unicodeOfPWideString(ps), lengthOfPWideString(ps)); } The first thing you have to do is look at the doc. https://www.cop...

Thank you for your response. We strongly suggest you do use PepperMill and then fix any code you decide should be improved. This will save you a good deal of time and energy. This is OpenSource. Saving time wasn't really the goal. I still have to look at everything. Having one black box magically co...

All, Stumbled into this today. Qt 4.8 had int lastIndexOf(const QRegExp & rx, int from = -1) const int lastIndexOf(QRegExp & rx, int from = -1) const In porting some code I believed the method existed in CopperSpice but now used QRegularExpression. The compiler quickly proved that wrong. The...

I'm having brain spasm porting (someone else's) debugger code to CopperSpice so I can have a debugger that lets me look at a CopperSpice QString. Porting by hand, not using the tool, because I don't want to be riding in that car if it goes off the rails. Well, that and this needs some restructuring,...

The big stinky chunks have officially hit the fan in the Qt world. Commercial customers of Qt 5 have to buy a subscription license for Qt 6. Last time I looked at anything related to the "subscription license" the gist of it was "if you stop paying you have to pull your product from m...

Just stumbled into this and passing along. https://www.theregister.com/2017/05/19/new_version_of_os_2_arca_os_5/ Qt 3.x and Zinc used to be big on OS/2. https://www.arcanoae.com/arcaos/ I haven't dug in to see how current the C++ compiler is nor did I dig in to see if CopperSpice could be built 32-b...

I'm looking at the doc trying to use an animated gif for a busy indicator. This is usually simple. Couldn't figure out why not working on CopperSpice. qDebug() << "supported formats: " << QMovie::supportedFormats(); Ubuntu 20.04 LTS Choosing xcb gl-integration based on following priority (...

Just some things I stumbled on while running valgrind on a fork of Diamond. These appear to be leaks inside of CopperSpice in various places. These aren't all from the same valgrind run. They could be some normal valgrind confusion. It appears QTextDocumentLayout has a small memory leak ==59076== 4 ...

all, I tested this out on Fedora (current) and Ubuntu 20.04. This is what QFileDailog looks like. https://www.logikalsolutions.com/wordpress/wp-content/uploads/2020/09/file-dialog-1.png According to the doc it should be providing the "system file dialog" (or wording something like that). O...
