Fix compilation error

[Ansa89]

Environment:

• linux 32 bit
• QT 5.2.0
• gcc 4.6.3

On given environment, that piece of code fails building: g++ -c -pipe -O2 -std=c++0x -Wall -W -D_REENTRANT -fPIE -DQT_NO_DEBUG -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -I/opt/Qt5.2.0/5.2.0/gcc/mkspecs/linux-g++ -I../projectfiles/QtCreator -I../src -I../submodules/ProjectTox-Core/toxcore -I/opt/Qt5.2.0/5.2.0/gcc/include -I/opt/Qt5.2.0/5.2.0/gcc/include/QtWidgets -I/opt/Qt5.2.0/5.2.0/gcc/include/QtGui -I/opt/Qt5.2.0/5.2.0/gcc/include/QtCore -I. -I. -o main.o ../src/main.cpp In file included from ../src/ouruseritemwidget.hpp:20:0, from ../src/mainwindow.hpp:22, from ../src/starter.hpp:20, from ../src/main.cpp:17: ../src/editablelabelwidget.hpp:33:29: error: expected ‘;’ at end of member declaration ../src/editablelabelwidget.hpp:33:31: error: ‘override’ does not name a type make: *\ [main.o] Error 1

override is a valid C++11, g++ 4.6.3 just doesn't support it, update to either 4.7 or 4.8.

I can't update gcc. I will close the pull request as it's more my fault than your, and keep remove the "override" on my local clone.

@Ansa89 That's strange that your compiler doesn't bark on the other overrides that are in the code, like here, or here, or even here.

The time of your issue matched the time when I updated that exact file that you had issues with, the editablelabelwidget.hpp, so I assume you already had other source files compiled into object files by a compiler that supports C++11 overrides, then you pulled my updates, changed the compiler on the one that doesn't support C++11 overrides, and the compiler, being smart enough, tried to compile only modified source files, that's why it barked only on that single override and no others.

Did the C++11-compliant compiler not suit your needs that you have changed it? : )

[Ansa89]

That's not exact: I always do a "make clean" and start from the ground with the new compilation. This issue was here since the beginning (from the first clone, I always removed that "override" in order to compile).

Checking the other files ("src/elidelabel.hpp" and "src/esclineedit.hpp"), I noticed I had modified those as well (my fault not reporting that).

For these reasons I think I never had a C++11-compliant compiler (and ATM I'm unable to update the current compiler).

[nurupo]

I see, than that means that gcc 4.6 already implements some of C++11 features, because there are a lot more of those than four overrides used in the code; good that you didn't have to change all of them : )

[Ansa89]

Yes, I was lucky.
