[SOLVED] Qt 5 Code Editor Example



  • I made a new project and copied and pasted the code present in this: http://qt-project.org/doc/qt-5/qtwidgets-widgets-codeeditor-example.html

    However when I try to compile it says:

    mainwindow.obj:-1: error: LNK2019: unresolved external symbol "public: __thiscall CodeEditor::CodeEditor(class QWidget *)" (??0CodeEditor@@QAE@PAVQWidget@@@Z) referenced in function "public: __thiscall MainWindow::MainWindow(class QWidget *)" (??0MainWindow@@QAE@PAVQWidget@@@Z)

    The code should work but it doesn't :S



  • Do you have an implementation of CodeEditor::CodeEditor(QWidget *parent) in codeeditor.cpp?

    If you installed Qt using an installer from qt-project.org then you can find this example in Qt/Examples/Qt-5.3/widgets/widgets/codeeditor
    Try the project from that directory. Does it work ?



  • Fixed it, it must have just been a weird bug in that project file. Copying everything over and running it worked fine.
