I haven't added an option for that, but you could hack the introjucer itself and change the L+F - it'd be a one-line change.

Hi Jules,

thanks for the quick answer, but i already had tried it before posting.

It give me an error when running in the following:

void IntrojucerLookAndFeel::fillWithBackgroundTexture (Component& c, Graphics& g)

{

&nbsp;&nbsp;&nbsp; dynamic\_cast\<IntrojucerLookAndFeel&\> (c.getLookAndFeel()).fillWithBackgroundTexture (g);

}

Gives this error:

libc++abi.dylib: terminating with uncaught exception of type std::bad\_cast: std::bad\_cast

Where should i put the declaration: "LookAndFeel::setDefaultLookAndFeel(&lookAndFeelV3);" ?

I put it on MainWindow.cpp.

No, that's the wrong thing to change - look at&nbsp;EditingPanelBase::lookAndFeel instead.
