@rtavakko I'm so pleased to hear the working solution! Thanks for sharing the good news :)

@Paulus_rin Hi QDir is just a helper class to work with files and folders. But it cant make a local folder public to others or things like that.

No, you have to find another non-Qt way.

@Christian-Ehrlicher said in Debug or assert in Popup requires machine hard reboot!!: It's an OS thing and can't be handled by the debugger (which has nothing to do with the QtCreator IDE btw). You will have exactly the same situation with the MSVC ide. And no a simple popup will not create such a situation as long as you don't set the breakpoint in the show or focusIn event of the popup. This shouldn't be the case. I've never hit such a limitation while debugging. I think this is simply some kind of bug/idiosyncrasy between gdb and the window manager/GUI. @JonB said in Debug or assert in Popup requires machine hard reboot!!: But... what is going on here?? Ctrl + Alt + Fn switches between the different terminals you have attached (ttys, or - and you're going to love this - teletypewriters). You usually have multiple of them running, as far as I can tell F1 to F7 are pretty much standard, and n in Fn is obviously the identifying ordinal. I'm afraid I come from the days of UNIX and vt100 terminals, the days when Programmers were Programmers, and nobody was vegetarian ;-) Yeah, we know you're old. ;P There were no windows or function keys. This has nothing to do with windows or function keys. Where is this documented so I can read up? Honestly, I have no idea. I've picked it up somewhere along the way, but I imagine linux/your distro's docs/wiki should have an explanation. What is the relationship between the 5/3 runlevels you mention and which keys? There's no keys for that one. init is a command line utility (I believe a shell script) that switches between the runlevels. For me on Debian there are 3 (formally 4) runlevels that are available: 0 is shutdown 1 is maintenance mode (single user, single terminal, bare bones functionality), call it the linux version of "Safe mode" 3 is multiuser no GUI mode, I get all the TTYs attached in it, but the GUI related stuff doesn't get started. Basically what one'd get if one were to be running a server/no-GUI machine 5 is multiuser + GUI, same as 3 but the window manager and all its associated daemons and such get started. So if I want to restart the window manager: $> su - $> ****** $> init 3 $> init 5

Hi In a network, there is a router with a firewall in front and it blocks incoming connections. So when your app tried to talk to another app over internet it wont be allowed in. One can tell the firewall that its ok for a given port and if traffic comes, then tell it where to send the traffic (the ip of the pc running the app) This is called port forwarding. However, if your app is to be used by other people this is really not an option to ask them to open ports. Can you tell us what the app does and what you wish to do ?

Hi This worked pretty well https://github.com/Bringer-of-Light/Qt-Nice-Frameless-Window

Since you cloned using git, did you install Perl ?

@SGaist , thank you, its now on my list of things to do.

I have the same problem. Windows 10, Dos-Command: pip install cx_freeze My Setup-File: from cx_Freeze import setup, Executable setup(name = "PQTTexteditor" , version = "1.0" , description = "Barrierefreier Texteditor" , author='Markus Lemcke', author_email='info@marlem-software.de', url='https://www.marlem-software.de', executables = [Executable("PQTTexteditor.py")]) Build exe-File: python setupwin.py build Try to start Programm: PQTTexteditor.exe following error message comes: This application failed to start because it could not find or load the Qt platform plugin "windows" in "". Reinstalling the application may fix this problem. Question: What can I do?

i got its solution : "query->seek(0)" added before int st = query->value(0).toInt(); and it happened

Problem solved using if(d.open(QFile::WriteOnly | QFile::Append)) to open th file

Solved. I think this was happned because of beautifier plugin - after I install it I've got this problem. To solve it you just need to reset Qt settings. To do that just delete two QtProject folders from: %SystemDrive%\Users%USERNAME%\AppData\Roaming\QtProject and %SystemDrive%\Users%USERNAME%\AppData\Local\QtProject. That's it. I hope it will help someone.

Thanks for the help, I'll look into it more. Closing this thread

@JonB said in MingW: A lot of warnings + too slow compiling: switch any anti-virus off on Windows? In this Windows machine, I don't have anti-virus or firewall... @JonB said in MingW: A lot of warnings + too slow compiling: vary by factor of 100x !! Incredible!

Of course, I'm not talking about all the controls in the program. I don't need it. This is purely for the case where there are few lineEdit. To erase the text in them all, or write something the same. Or to change the color of all the buttons for example. Then I'm going to need a separate array of pointers on the buttons. Of course, I'm not going to collect in one array of pointers for the controls of different purposes. There will be no practical benefit to this.

@jsulm said in Storing QTextCharFormat and QColor to text file?: QTextStream & operator<<(const QTextCharFormat&) Hi, I have searched around how to write overloaded function for the operator, but I have not seen any example on the syntax you're using. I have declared QTextStream & operator<<(const QTextCharFormat&) in the class' header file, and in the source file, it should be something like this? QTextStream &SettingsDialog::operator<<(const QTextCharFormat &b) { stream << "font: " << b.font().toString() << " font-family: " << b.fontFamily(); return stream; } But I don't know where do I pass in the stream in the implementation.

okay, i have to ask in a python forum !?

Thanks for your feedback @jsulm @JonB @J-Hilk
