Ok so suppose I have this:

#define MYDIRECTIVE

#ifdef MYDIRECTIVE
bool myswitch = 1;
#else
bool myswitch = 0;


Eclipse will go ahead and white out the bottom half of that if statement (because MYDIRECTIVE is defined), which is fine, but I'd like to change the color of that highlighting. I initially thought to look here: Windows->Preferences->C/C++->Editor->Syntax Coloring->Preprocessor

However, all I find there is how to change the coloring of the preprocessor text, not the highlighting. Any ideas? I'm using Eclipse 3.7.0 with the eclipse color theme plugin v0.11.0, running on ubuntu.

For CDT, I've found this in Windows > Preferences > C/C++ > Editor. In the list of "Appearance Color Options" you'll find the "Inactive Code Highlight" sets the value for disabled code. In the example you presented above, the last 2 lines would be highlighted by this color.

Exists there a way to just "gray-out" disabled code like VS?

Since this is for C/C++, you might get better help in the Eclipse CDT
forum. Different languages have their own editors in Eclipse.

Thank you for your reply. I am (more or less) new to Eclipse ... Using Mars.1 and C/C++ GCC project.

EDIT:
"Eclipse CDT" is part of the bundle we've installed.
