Macros in the slot section

[Caius Aérobus]

Hello,
I would like to use a macro in the slot section but the moc preprocessor encapsulates it BEFORE the C++ preprocessor processes it, which leads to an error. How to cope with this issue?

Macro function:

#define SetFloatSlotMacro(name, arg) \
  void Set##name(QString arg) {this->Set##name(arg.toFloat());}; \
  void Set##name(float arg)

#define SetFloatSlotMacro(name, arg) \
  void Set##name(QString arg) {this->Set##name(arg.toFloat());}; \
  void Set##name(float arg)

To copy to clipboard, switch view to plain text mode 

Resulting code in moc generated file:

case 4: { int _r = SetFloatSlotMacro((*reinterpret_cast< IdleToWalk(*)>(_a[1])),(*reinterpret_cast< speed(*)>(_a[2])));
            if (_a[0]) *reinterpret_cast< int*>(_a[0]) = _r; }  break;

case 4: { int _r = SetFloatSlotMacro((*reinterpret_cast< IdleToWalk(*)>(_a[1])),(*reinterpret_cast< speed(*)>(_a[2])));
            if (_a[0]) *reinterpret_cast< int*>(_a[0]) = _r; }  break;

To copy to clipboard, switch view to plain text mode 

Error at compile time:

moc_Avatar.cpp:94:1: error: pasting "Set" and "(" does not give a valid preprocessing token

moc_Avatar.cpp:94:1: error: pasting "Set" and "(" does not give a valid preprocessing token

probably that can be achieved by adding a pre-processing step into the build process with qmake: qmake-environment-reference.html#customizing-makefile-output
Haven't tried myself yet, though.

Hmmm, seems not to be easy, I suspect (hope) there is an easier way to cope with this issue...
