Re: [Lazarus] Widget set definitions

2017-02-13 Thread Kostas Michalopoulos via Lazarus 
The LCL package has this in custom definitions for dependent packages:

-dLCL -dLCL$(LCLWidgetType)

So Lazarus simply defines the LCL and LCL at compile time.
 is one of the subdirectories in lcl/interfaces.

uses InterfaceBase, LCLPlatformDef;

set';


OK, Thanks. So I can see how I can derive the names etc. from that, it 
appears to have been supported since the dawn of time, and linking to it 
is still going to be no more intrusive than some of the other stuff 
that's already in my diagnostic unit.


But out of curiosity, I'd still be very interested to know how the 
compile-time definitions like the ones in my example are generated :-)

uses InterfaceBase, LCLPlatformDef;

widV:='Linked with '+LCLPlatformDisplayNames[WidgetSet.LCLPlatform]+'
widget set';

They are defined in the LCL package. See "package options -> usage -> 
custom" and "Compiler Options -> Custom Options".
