Re: [Lazarus] For QtLCL users - new feature, need testers

I'm working on project based on pure Qt 5.1, I needed to use C++ instead of FPC :/ . Those libs are amazing, not only GUI but for example QMultimedia, QNetwork and websockets. I'm wondering if exists any tool which can automatically convert Qt API headers into FPC. For example gtk3 headers for FPC are generated by some tool (don't remember the name). Was current Qt4Pas unit written manually line by line? My dream is to write pure Qt application (I'm not interested in LCL) using FPC for all platforms as I'm doing now with C++ Yes, there is actually tool which can create modular Qt libs, but it needs a lot of time to create C bindings. Feel free to create it using doxygen. From times of Kylix 3 Andreas Hausladen created QtC bindings by using doxygen (which creates classes in xml) ,and then via small console program he created libqtc and QtLibrary.pas. Of course that was all in one library binding, but it can be separated into various C bindings. I support your idea too, but Den Jean created current bindings and he is working on that part, so maybe you should ask him , or maybe we can provide to him some bounty to create separated qtc bindings (libQt4Core - libQt4PasCore,libQt4Gui - libQt4PasGui, libQt4Network - libQt4PasNetwork etc etc). zeljko 2013/10/12 zeljko zel...@holobit.net mailto:zel...@holobit.net On 10/12/2013 04:38 PM, zeljko wrote: Hi all, Today I've commited new feature of qt widgetset (r43218) - scrollable forms.

[Lazarus] Lookup field
Hi guys! i am trying to make a lookup field and i found that i can't use a dataset that's not on the same form/datamodule. is there a way to bypass this? Regards Chris -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Students tend to overfocus on embellishing forms etc, and not spending their time on the more problem-solving oriented assignment. What's a form worth without a task and event handlers? (essentially to all replyers) The course changed from TP to Delphi (as tool) and suddenly a lot more time was spend on non-programming. Not everything vaguely related (to IT) is part of a /programmer's/ course. We knew students could click around in GUIs just fine. That was not what the course was about. Btw, the course abandonned TP because too many students were unfamiliar with the concept of console apps. Explaining it took a too large part of the course, and due to its (101) nature it had to be early in the curriculum. Probably because dolling up the UI is easier and gives instant-gratification. Modern (portable) devices are GUI based I hope they use it in the Mobile development class then. This was not the mobile development class. This was introduction to programming (not UI design, not Mobile, not, not, ...) :-) So the idea is that the students, euh, spend their time programming. Anyway, the whole post was meant more or less as an argument that a good educational tool should 1) be quick to start using (so not TP) 2) not contain parts that are not part of the course and detract too much. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Re: [Lazarus] Graeme would love this, or not, I think
Well, after all if it's basic course, should they use something from Children list of this page? http://en.wikipedia.org/wiki/Educational_programming_languagehttp://en.wikipedia.org/wiki/Educational_programming_language#Historical Surprisingly, pascal is the only in historical section.
