(Make sure 'QTextCharFormat' is registered using qRegisterMetaType().)

when I enter Tcl source command on QTextBrowser , then I get this error any idea why we get this error

The error message tells you what you can do to solve the error: Make sure 'QTextCharFormat' is registered using qRegisterMetaType()
If you're using Queued Connections you have to make sure all types are registered with qRegisterMetaType.

@Qt-Enthusiast
Hi
try to register QTextCursor and QTextCharFormat
with qRegisterMetaType
qRegisterMetaType<QTextCursor >("QTextCursor ");
qRegisterMetaType<QTextCharFormat>("QTextCharFormat");

BEFORE you try to use it.
so like in main.cpp

Qt Enthusiast

I did

I am still getting the error

i did

Q_DECLARE_METATYPE(QTextCursor)
Q_DECLARE_METATYPE(QTextFormat)

I am still getting the error

mrjj

@Qt-Enthusiast
and you did use
qRegisterMetaType
too ?

Qt Enthusiast

No I did not use that

mrjj

@Qt-Enthusiast
But that is the one you must use.
Q_DECLARE_METATYPE is not the same.

No I did not use that

And then you wonder why it does not work... really strange. The error message exactly tells you what to do and you're ignoring it even two people telling you to do so...

Qt Enthusiast

after that also it is crashing
