define PRE_PROCESSOR - best location?

[ustk]

Is there a prefered place where to define a new preproc constant?
Is the header of the component/class in question a good place to put it as we can see sometimes?
Does it depend on the scope?

I want it to be consistent in order to contribute to Hise properly...

Also, it would be great to have all the preproc listed in the doc

If you add them at the .h file of the module (so hi_tools.h in /hi_tools) and prepend a

/** Config: HISE_MY_PREPROCESSOR

Describes what the preprocessor does
*/
#ifndef HISE_MY_PREPROCESSOR
#define HISE_MY_PREPROCESSOR 0
#endif

it can be selected in the Projucer, which is quite handy (take a look at how the other preprocessors are defined there). I would also prepend HISE_, so that it won't clash with other preprocessors.

@Christoph-Hart Cool thanks :)
In this case it's for a value -> HISE_PANEL_MOUSE_DRAG_THRESHOLD or something like this... Currently set to 4px, but I always use 0.
Or, a bool, like HISE_DISABLE_PANEL_MOUSE_DRAG_THRESHOLD might be good enough, I can't imagine one wants to set it at 50px
