Qt Creator and other tools

https://bugreports.qt.io/browse/QTCREATORBUG-31805

Right now I just don't have the time to consider that

@Nadia220 said in QApplication: Yes, I am from Russia The Qt Company decided to block Russian IP addresses in 2022... :( So the official online Installer currently doesn't work in Russia anymore. It's sad, but we can't do anything about it. Some day they will unbann it again, but until then you have to find other ways to install Qt... as you said, for example, via GitHub and build from source. There is a file in the Msys/mingw/include file, like a QAplication document, but there is no folder, I do not understand what is wrong 🤨 Your "File or directory not found" is a generic message when something wasn't found. Since you probably #include <QApplication> in your main.cpp it is looking for a qapplication.h header file... and can not find / locate it... Either your Qt installation isn't 100% right and/or some paths are not set. @Nadia220 said in QApplication: What is QT_DIR? I have not seen this QT_DIR is an environment variable which helps to locate your Qt installation "home" dir... Something like "C:\Qt\6.8.0\" Can't help you with Msys, but when using QtCreator, you should find your Qt installation. Check if your JSon config files for your VSCode workspace are really configured correctly (compare with the video and change your paths accordingly so it matches your Qt installation on your computer)

@xiaomizhou said in Creator: Cannot write file c:\Users\AppData\Roaming\QtProject\gtcreator\debuggers.xml: Insufficient disk space: @ankou29666 Thank you for your reply, but I don't know whether I need to delete some files in c:\Users\AppData\Roaming\QtProject\gtcreator？ check disk occupation on C:\ drive, and if it's full, you can delete any file you don't need anywhere on C:\ drive.

Yes I used Q_OBJECT and yes the class is initialised. In the end I gave up and use QCoreApplication::translate("QLinearGradientCtrl", "text") as tr("text") wasn't working. QLinearGradientCtrl::QLinearGradientCtrl(QWidget * parent, QColor start, QColor end) : QWidget(parent), m_Gradient(0, 0, 1, 0), m_Width(GCW_AUTO), selectedPeg(NONE), lastSelectedPeg(NONE), m_LastPos(0), m_showToolTips(true), m_Orientation(Orientation::Auto), startPegStop(0), m_LeftDownSide(true), m_RightUpSide(false) { m_ToolTipFormat = "&SELPOS\nPosition: &SELPOS Colour: R &R G &G B &B\nColour: R &R G &G B &B\nColour: R &R G &G B &B\nDouble Click to Add a New Peg"; //m_Impl = new QLinearGradientCtrlImpl(this); m_Gradient.setColorAt(0, start); m_Gradient.setColorAt(0.001, start); m_Gradient.setColorAt(0.999, end); m_Gradient.setColorAt(1, end); setFocusPolicy(Qt::StrongFocus); // Make sure we get key events. stops = m_Gradient.stops(); // Grab the gradient stops endPegStop = stops.size() - 1; setToolTip(QCoreApplication::translate("QLinearGradientCtrl", "You can use the Up-Arrow, Right-Arrow, Left-Arrow, Down-Arrow;\n" "Page-Up and Page-Down keys to move a slider after you have selected it\n" "with the mouse.")); } Is how it now reads...

which one is correct, the complete blue or the one with the red number? Can you share you proejct?

@cristian-adam I know about the Beautifier and have used is as a backup solution. I would prefer to get the ClangFormat plugin working, though, as I'd like to be able to "format as I type" or "format on tab". I never noticed that a clang-format executable was included with Qt Creator. I actually have a different one from an LLVM package, too - maybe that's the problem? Like, perhaps the plugin picks the "wrong" version of the program and doesn't like it somehow? I imagined that the plugin(s) would use a library rather than the actual clang-format command, but perhaps that's not the case.

@hy1011 How do you debug your plugin? Do you run a self compiled Qt Creator inside the debugger? Or what do you do?

If you want to contribute to Qt you should start here: https://wiki.qt.io/Qt_Contribution_Guidelines

unfortunately it does not seem to be an option, because I also liked the old more :(

Oops sorry too little sleep ..

@Prabhakaran said in build process has failed: ld: error: undefined symbol: events::parser::ParsedEvent::argumentValueInt(int) const So fix this - check where this function is defined and make sure the source gets compiled. Since it's from QGroundControl you should ask there if this problem is already known. Nothing Qt can do here.

The problem is the Set "HOME" option here: [image: e97c867f-8c53-4933-b04f-679651e76716.png] (from Version Control in Preferences dialog.) The tooltip for this option suggests that it will set HOME to the location I want, but it seems like it doesn't really. Instead it changes HOME from the desired location to something else. If I uncheck, everything works a lot better. Perhaps part of the issue is that I didn't update everything fully when I tried to change my home directory earlier. Not sure what to do, there, really...

I am using an offline installer, but not for Windows - for Linux. I'm not sure that bug report applies.

Hi, Start it with the debugger so you should get the point of crash.

Then you can close the bug.

i solved the issue Clear Qt Creator Cache: Sometimes, cached data causes Qt Creator to not detect updates or changes correctly. You can try clearing the cache by: Deleting the .config/QtProject and .local/share/QtProject directories under your home directory.

Hi @QtSurfer , Please help-out for this issue
