@JonB I'm on Fedora... In any case I would expect to receive the keys before the OS as I have the focused window with the input...

@Ylvy What would you expect to be any faster than this? It has to search all directory entries recursively on all mounted volumes. That takes a while :) Linux filing systems don't have a magical call for finding things other than you looking at the filename retrieved, and these days I don't think Windows has a faster native call. This is also why OSs offer features like Windows "indexing" or Linux locate, so you can look up previously cached answers quickly!

@SGaist, sorry for the late reply. That is exatcly what I was looking for. Combining the readyRead() signal and buffer size limit allowed me to save data to a temporaray file without using a lot of memory. Thanks.

@GeorgesS said in Qt5Core dll gets overwritten at compilation: Hi, I have a c++ project using qt 5.12.10 and I recently upgraded it so it can work on 64-bits system. When I get my dll from APP\Qt\qt5.12.10... repository, it works fine but when I compile (release or debug), my qt5core.dll in my project gets overwritten ("modified on" compilation time). Then, when I launch my project, every icons in my mainwindow won't show. If I replace the qt5core.dll with the one from the APP\Qt\qt5.12.10... repository, my icons are displayed properly. Does the compilation look for the dll where it shouldnt ? Or is there something in .pro file that overwrites it ? It only does this for qt5core. I am using core, network and gui modules. Compile with QMake, MinGW-64 bits and using windeployqt. It's a project that I inherited from so I'm not so familiar with it. Double-check the environment and build settings in your project to ensure that the correct paths to the Qt DLLs are set. Make sure that the directory containing the DLLs from the APP\Qt\qt5.12.10 repository is listed before any other directories in the system PATH variable.

@JonB I have found that my code has issue due passing value using pointer. so passing by value have resolved the Crash issue. Now my error list is not passed by pointer its passed directly. This issue identified by GDB. As well as valgrind tool also helps.

@voltron I don't read QWizardPage::registerField() as making the widget mandatory to fill out? Only if you choose to make it compulsory.

@SimonSchroeder Good news ...

@serkan_tr I added the variable "PKG_CONFIG_PATH" to the environment variables and the problem was solved

@ChrisW67 Thanks. I don't totally understand how this works. Given that you write QString % QString, why does C++ go off and match that against some QStringBuilder template?

@SimonSchroeder No I only use the screen of my laptop

For Linux deployment we are using AppImages. Besides that there is also Flatpack and Snap, but we settled on AppImage. These will package all dynamic libraries and the executable into a single image that can be executed and launches the actual app. Still, you'll need to use an older Linux distribution (some required tools check for this). We are using a combination of linuxdeploy and linuxdeployqt to create the AppImage. linuxdeployqt is better at fetching the Qt dependencies, but other things work better with linuxdeploy. This would resolve your glib issues as the lib would be included in the AppImage. This is not 100% fool proof. However, we compile on CentOS 7 and it works on CentOS (and most likely also RedHat), openSuSE (and most likely also SuSE Enterprise), and Ubuntu 18 and upwards. We used to have an additional AppImage for Ubuntu 16, however this did not work on Ubuntu 20 anymore. We only have very few clients using the Linux version of our app and they mostly use the most recent Ubuntu version. But so far, we don't have any bigger problems with this approach.

@SGaist I have checked the bug with frozenColumn example on Qt 6.4.3. It is still impossible to select an extended range, that includes cells from two QTableView, with mouse clicks. I suspect that this is a bug that cannon be fixed with additional code from me. Because the addresses of currently selected cells in each table view are the same (as it should be). And also the selection with keyboard is okay. Somehow mouse clicks select extended range just inside single table view (though the table views have the same selection model). Can someone give me an advise about possible workaround for this selection bug?

@mzimmers thank you for your message. Yes i had a look at few examples. But then I get confused because of the terms like Camera, Light, Euler Angles etc. I guess all these terms are important for 3d visualization. Can you or someone suggest me some good tutorial on this or you guys think that Qt documentation is sufficient? Because I couldn't understand these terms and hence will not be able to rotate the 3d Cube.

@Kevin470 Hi, I have exactly the same problem with you and i also have Trend Micro Security on my laptop. I have been searching this issue for a few days. Have you tried to close the antivirus software? Could this solve the issue?

Hi, Which performance are you looking for ? One important note: just throwing threads at your problem is not the solution. You also have to take into account what they do. For example, if you have a disk intensive task and try to run many of them in parallel, you'll quickly see a performance hit because of the speed of the disk.

@mpergand Thank you - that's what I needed!!! I adjusted the layout top and bottom margins to 2 and also the spacing to 2. That worked a treat! Thanks again, David
