Overview

Proxy for org.eclipse.swt.graphics.Font

This class can be optionally used with WidgetProxy to manipulate an SWT widget font (reusing its FontData but building a new Font)

Otherwise, if no WidgetProxy is passed to constructor, it builds new FontData

Invoking ‘#swt_font` returns the SWT Font object wrapped by this proxy

Follows the Proxy Design Pattern

Constructor Details

#initialize(widget_proxy = nil, font_properties) ⇒ FontProxy

Builds a new font proxy from passed in widget_proxy and font_properties hash,

It begins with existing SWT widget font and amends it with font properties.

Font properties consist of: :name, :height, and :style (one needed minimum)

Style (:style value) can only be one of FontProxy::FONT_STYLES values: that is :normal, :bold, or :italic
