◆ createFont()

core::style::Font * dw::fltk::FltkPlatform::createFont	(	core::style::FontAttrs *	attrs,
		bool	tryEverything
	)

virtual

Create a (platform dependent) font.

Typically, within a platform, a sub class of dw::core::style::Font is defined, which holds more platform dependent data.

Also, this method must fill the attributes "font" (when needed), "ascent", "descent", "spaceSidth" and "xHeight". If "tryEverything" is true, several methods should be used to use another font, when the requested font is not available. Passing false is typically done, if the caller wants to test different variations.
