@mzimmers said in Terminology for copying sketch and rotating: Since when? You may've not noticed, but I'm very sarcastic (also pretty vulgar). Usually I try to keep it in check around the forum, though. :)

@Chris-Kawa said in Ahhh another move ... I shall post here from now on to save energy: People's time is limited. "Precious" is more like it. If you convert your time with your experience in mind, or mine, or @SGaist's, or whomever's really, in money it's going to be one long, long bill. And even then, nobody's going to give you your time back, so in that sense - it's priceless.

@JoeCFD I have Qt account and dutifully used Maintenance Tool to "update " to 6.2. I am unable to figure out HOW to execute 6.2. I used "options" and cannot change from15.5.2 to 6.2 no matter what I try . Yes, my reply definitely belongs here. It makes for much fun to chase my posts. Too bad I cannot reply directly - as a new user I cannot . O wait ... I got over 600 posts and I am still "new user" limited to wait 600 seconds between posts.

@Shawn-Driscoll It is hard to beat python with a pyqt front-end for proof of concept and rapid prototyping. Id never stop there and consider the project done though. too many ambiguities in python to base a high availaiblity system solely on a python/Qt app.

@Chris-Kawa said in Decision... decision ... rant: In short - world is not binary on a whole. Just in the split seconds when you make every small decision in a never ending series of small decisions. On a whole it's all sorts of shades of gray. Everyone decides who they want to be in every moment of their life and everyone else decides how to react to actions of others. Small decisions can be binary all the same. It's the self-organizing complexity that "generates" the grayness of the big picture I'd argue.

@kshegunov said in Quiz Time! Prepending items to QVector: but what your task sounds like is actually a stack, not a vector Indeed, this was an iper-semplification of my problem to solve the academic dilemma. I agree that a stack or, as @jeremy_k already pointed out, using reverse iterators would achieve the same

April 2021: Since the last time I looked, there appears to be Qt for small business, where businesses making < 250K $US per year can license Qt for $499 per year... Extra distribution fees apply for embedded devices. This is an affordable thing for small businesses.

@Kent-Dorfman It's still alive: in this forum! I can be grumpy at times when answering, and I know of a certain expert here whose replies are very good yet often delivered in a "non-gentle" fashion... ;-)

Hi Everyone and thank you so much for your help. Actually i have solved the Problem of the Linker by adding the Source Code of the libraries to my Ptoject (Add Existing Files .... / Add Existing Directory .... ) to bypass the linker. So thank you so much.

@tham the very first stupid decision was to create QtC........

@Joel414 said in Bluetooth "news": @AnneRanch said in Bluetooth "news": I can turn on bluetooth SETTING n Ubuntu 20.10 Many laptop computers have a hardware switch or key combination to turn Bluetooth on and off. Look for a switch on your computer or a key on your keyboard. The keyboard key is often accessed with the help of the Fn key. AS I said - bluetooth is not, IN MY OPINION, subject to many posts. My comment was directed to MAJOR and undocumented changes implementing / enabling bluetooth in general in Ubuntu 16 and then in Ubuntu 20 . In 20 I could not get out of "airplane mode " to "turn the bluetooh on" . On Ubuntut 20 .10 it works as expected - but it no longer appears as "bluetooth is on" on top status bar. Top status bar had few other indicator icons ALL BY DEFAULT - no setup was necessary. Now on latest Ubuntu they are all gone. Maybe because nobody was using them ? But this is QT forum and OS problems are "off topic ".

@Kent-Dorfman Was he teaching object oriented using modula, or was he confused about what modula was out of the box? I have talked to a few people who use languages without object oriented support, but program them in the object oriented style. open65241 is one such project that programs C in oop style.

My OP was a bit dense, suffice it to say that I wish that Qt was completely free and open source while being mutually beneficial for users and contributors.
