Brainstorm

OK, I got it figured out. As @JoeCFD suggested, I needed anchors instead of Layout.*. Someday, I'll commit this to memory -- @fcarney will probably only have to remind me another 100 times... Thanks for the help.

Since @JKSH answered my original question, I'm marking this as solved. I'll bring up my other questions in a new topic with a more accurate title.

so no group feedback on this question but I did manage to locate (by accident) a utility that accomplishes the task. xdotool windowmove {windowid} {x} {y} uses XTEST extension which insers emulated mouse and keyboard events to the X server.

Yes, that would the the correct sub-forum.

You've got Qt in the title and qt-creator in the command. Qt 4.12.4 in the title and /qt6-build in the command What are you actually trying to build? Qt or Qt Creator? Which version and if creator then against which Qt? On what platform?

Hi and welcome to devnet, That's a bit too vast of a topic to have a simpler answer. What element of Cyber Security do you have in mind ? At what level ? Cyber Security starts from giving people access to certain hardware / applications to the boot process of your machines/devices, the kernel/OS they are running, the applications you are using on them, the libraries that composes these applications, the devices you plug in the machines, etc.

@NutKey Please post in correct forum. Please translate Chinese to English, so people not speaking Chinese can actually understand the messages you posted.

The broader argument is that pausing a thread is a misuse of them. Also, you need to consider that the qt thread abstraction may not be a true system level thread, but instead a pseudo-thread that supports the common threading api and behaviour (to some extent). As for pause/yield/etc as in coroutines...seems like it's a 20 year full circle back to the era of cooperative multi-tasking, when the favored model has clearly become preemptive MT. Seems to me that the hint about how qt threads exist would be whether std::this_thread::sleep_for() works as expected, or does it introduce side-effects?

Hi and welcome to devnet, Any chances that you are working on Windows ? In any case, you should read this page of the documentation.

@phreed said in Distribution of Qt via `conda-forge`: What I am looking for is advice on legally distributing Qt. If you plan to use Qt under the (L)GPL license, then you just need to comply with the rules of the (L)GPL license. The git repo git://code.qt.io/qt/qt5.git only goes back to v5.3 The old branches are gone, but the tags are definitely still there. https://code.qt.io/cgit/qt/qt5.git/tree/?h=v5.2.1

Actually, my last remark reminded me that Windows has kiosk mode! https://docs.microsoft.com/en-us/windows/configuration/kiosk-single-app @Qt-embedded-developer - with this approach you don't need to worry, assuming your POS is a sole function of the host.

That's why setModel accepts a base class (usually abstract) so you can use several different models as they have a standard interface. Since you have a model that is used in several other objects, you would create the model in the class that manages all these objects. Model/View does not lock you to the Qt classes. It's a pattern that you can implement in different ways. From your description, it seems to be a good plan.

@Jiri-Rohlicek So it looks like the package manager put it somewhere where your user doesn't have to sufficient permissions. Sadly, I don't know how to fix it.

@SGaist and @Kent-Dorfman Thanks for your inputs.

@Mani_kandan As @jsulm and I have been saying. If you have data in a file you want to encrypt you have to read the file to get the data to encrypt, so there is no point keep asking whether you can do it without reading the file content. If you want to save the encrypted data back to a file you can do that. If you want the encrypted data to end up back in the same file as you read the encrypted data from: either read all the file content into memory, encrypt it, and write it back to the file you originally read from; or, read it a chunk at a time from the original file, write it encrypted a chunk at a time to a new, temporary file, and rename the new file to the original file right at the end.

@Mani_kandan said in in qt using openssl how to encrypt and decrypt the file: So can you help me out how to encrypt the file OpenSSL is not Qt. This is Qt forum. Why don't you read OpenSSL documentation (https://www.openssl.org/docs/)?

Ok, I think that these are the modules under the LGPL. I'm reading right now. If I find some troubles I will write here. Edit: I found this that maybe could be of help to someone.

@Violet-Booth and how is this related to the Qt framework?

If I may, there's no need for the loop, you should be able to directly stream the list object and not go manually with that loop.
