OmniWeb is a proprietary Internet web browser developed and marketed by The Omni Group, available exclusively for Apple Inc.'s Mac OS X operating system. It is available as a free download. ==History== OmniWeb was originally developed by Omni Group for the NeXTSTEP platform, and was released by Lighthouse Design on 17 March 1995 after only one month's development time. As NextStep evolved into OpenStep and then Mac OS X, OmniWeb was updated to run on these platforms. OmniWeb also was able to run on Microsoft Windows through the Yellow Box or the OpenStep frameworks. After Lighthouse Design was bought by Sun Microsystems, the Omni Group released the product themselves, from version 2.5 onwards. From version 4.0 onwards, OmniWeb has been developed solely for the OS X platform. OmniWeb is developed using the Cocoa API which allows it to take full advantage of OS X features. It uses Quartz to render images and smooth text. it will use multiple processors if available, and features an interface that makes use of Aqua UI features such as drawers, sheets and customizable toolbars. OmniWeb originally employed its own proprietary HTML layout engine that used standard API NSText components.〔(【引用サイトリンク】title=OmniWeb Release Notes )〕 However, this engine was very slow, particularly when scrolling, and was not fully compatible with the most recent web standards, such as Cascading Style Sheets. In OmniWeb version 4.5, the Omni Group adopted Apple's KHTML-based WebCore rendering engine, which was created by Apple for its Safari browser. On August 11, 2004, the Omni Group released version 5.0 of OmniWeb which included a number of new features. The most notable feature was an unusual implementation of tabbed browsing, in which the tabs were displayed vertically in a drawer on the side of the window (including optional thumbnail pictures of the pages.) Despite a certain amount of controversy over the merits of a tab drawer over a tab toolbar, the feature has persisted through the current version. On September 6, 2006, version 5.5 was released. Major new features include the use of a custom version of WebKit instead of WebCore, universal binary support, saving to web archive, support for user defined style sheets, a "Select Next Link" feature, FTP folder display, ad-blocking improvements, updated localizations, many other small changes and bug fixes.〔(The Omni Group - OmniWeb - Historical Release Notes )〕 OmniWeb was Omni Group's flagship app but as OS X web browsers improved—Apple eventually bundled Safari— and Omni successfully introduced other products such as OmniGraffle and OmniOutliner, OmniWeb's importance diminished. OmniWeb's price was successively lowered, first to $39.95, then on February 24, 2009, Omni Group announced that OmniWeb would be made available for free, a change from its previous price of $14.95. Despite assurances from Omni Group that the browser is still under development, there has not been a final release since 2012. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「OmniWeb」の詳細全文を読む スポンサード リンク
