implementing tr() results in exception?
-
Today I've been through a project replacing instances of "some text" with tr("some text"), the project builds with no warnings and no errors, however when I launch in the debugger I get an exception instantly:
Debugger encountered an exception: Exception at 0x6a432132, code: 0xc0000005: read access at 0x0, flags0x0 (first chance)Execution is halted on Q_OBJECT below:
class SendRDF : public QMainWindow { Q_OBJECTNo other changes have been performed.

@jsulm , Yes, that was the first thing I tried, I'm reading through:
https://doc.qt.io/qt-5/i18n-source-translation.htmlNot sure if I have jumped the gun in building before the implementation is complete? I just tried to include:
Q_DECLARE_TR_FUNCTIONS(SendRDF)It has a red underline, not sure if its available in Qt 5.9.2 ?
In the class where the exception is raised there two statics initialisated:
QString SendRDF::msstrAbort(tr("&Abort")); QString SendRDF::msstrTransferComplete(tr("&Transfer Complete"));Could this be the cause?
@SPlatten said in implementing tr() results in exception?:
In the class where the exception is raised there two statics initialisated:
Could this be the cause?Yes, this is probably the error source.
This is will done before Q(Core|Gui)Application has been initialized, so there is not translator available.
You cannot do this like this, you have to initialize the static members after QApplication has been initialized.It is an old maxim of mine that when you have excluded the impossible, whatever remains, however improbable, must be the truth. (Sherlock Holmes)

@SPlatten Did you try complete clean rebuild?

The compiler would break with an error if the macro would not be defined.

Why do you use this?
SendRDF::tr()should be enough. -
