LCL Defines
This page documents the defines that can be utilized to recompile the different widgetsets of LCL. It isn´t a compreensive list, but may become one as more defines are added.
Why use defines?
Defines allow to add non-standard functionality to LCL, test experimental features or to add debug output that helps testing the widgetsets.
Recompiling LCL with a define
To recompile LCL with a special define go to the Lazarus menu Tools -> "Configure Build Lazarus"
There add -d<DEFINE_NAME> on the Options box.
So if you wish to add the PassWin32MessagesToLCL define, you will add -dPassWin32MessagesToLCL to this box.
