<div class="textblock"><h2>Changes in Dw</h2>
<p>Related to the FLTK port, there have been many changes, this is a (hopefully complete) list:</p>
<ul>
<li>
<p class="startli">Rendering abstraction, read <a class="el" href="dw-overview.html">Dillo Widget Overview</a> and <a class="el" href="dw-layout-views.html">Layout and Views</a> for details. Some important changes:</p>
<ul>
<li>
<p class="startli">The underlying platform (e.g. the UI toolkit) is fully abstract, there are several platform independent structures replacing GTK+ structures, e.g. <a class="el" href="classdw_1_1core_1_1Event.html" title="Base class for all events. ">dw::core::Event</a>.</p>
<p class="endli"></p>
</li>
<li>
<p class="startli">The central class managing the widget tree is not anymore GtkDwViewport, but <a class="el" href="classdw_1_1core_1_1Layout.html" title="The central class for managing and drawing a widget tree. ">dw::core::Layout</a>.</p>
<p class="endli"></p>
</li>
<li>
<p class="startli">Drawing is done via <a class="el" href="classdw_1_1core_1_1View.html" title="An interface to encapsulate platform dependent drawing. ">dw::core::View</a>, a pointer is passed to <a class="el" href="classdw_1_1core_1_1Widget.html#a2e7d05212aabad32824fd577fb7e3dd7">dw::core::Widget::draw</a>.</p>
<p class="endli"></p>
</li>
<li>
The distinction between viewport coordinates and canvas coordinates (formerly world coordinates) has been mostly removed. (Only for views, it sometimes plays a role, see <a class="el" href="dw-layout-views.html">Layout and Views</a>). </li>
</ul>
<p class="endli"></p>
</li>
<li>
<p class="startli">Cursors have been moved to <a class="el" href="namespacedw_1_1core_1_1style.html" title="Anything related to Dillo Widget styles is defined here. ">dw::core::style</a>, see <a class="el" href="classdw_1_1core_1_1style_1_1StyleAttrs.html#aef2c1921311d44fd060aedf781e2a6b8">dw::core::style::Style::cursor</a>. <a class="el" href="classdw_1_1core_1_1Widget.html#a761535b4f71744668c78a81914002bd1">dw::core::Widget::setCursor</a> is now protected (and so only called by widget implementations).</p>
<p class="endli"></p>
</li>
<li>
<p class="startli">World coordinates are now called canvas coordinates.</p>
<p class="endli"></p>
</li>
<li>
<p class="startli">There is now a distinction between <a class="el" href="classdw_1_1core_1_1style_1_1StyleAttrs.html">dw::core::style::StyleAttrs</a> and <a class="el" href="classdw_1_1core_1_1style_1_1Style.html">dw::core::style::Style</a>.</p>
<p class="endli"></p>
</li>
<li>
<p class="startli">There is no base class for container widgets anymore. The former DwContainer::for_all has been removed, instead this functionality is now done via iterators (<a class="el" href="classdw_1_1core_1_1Widget.html#ab66387121a56322ea6e4168db857e013" title="Return an iterator for this widget. ">dw::core::Widget::iterator</a>, <a class="el" href="classdw_1_1core_1_1Iterator.html" title="Iterators are used to iterate through the contents of a widget. ">dw::core::Iterator</a>).</p>
<p class="endli"></p>
</li>
<li>
<p class="startli">DwPage is now called <a class="el" href="classdw_1_1Textblock.html" title="A Widget for rendering text blocks, i.e. paragraphs or sequences of paragraphs. ">dw::Textblock</a>, and DwAlignedPage <a class="el" href="classdw_1_1AlignedTextblock.html" title="Base widget for all textblocks (sub classes of dw::Textblock), which are positioned vertically and al...">dw::AlignedTextblock</a>.</p>
<p class="endli"></p>
</li>
<li>
<p class="startli"><a class="el" href="classdw_1_1Textblock.html" title="A Widget for rendering text blocks, i.e. paragraphs or sequences of paragraphs. ">dw::Textblock</a>, all sub classes of it, and <a class="el" href="classdw_1_1Table.html" title="A Widget for rendering tables. ">dw::Table</a> do not read "limit_text_width" from the preferences, but get it as an argument. (May change again.)</p>
<p class="endli"></p>
</li>
<li>
<p class="startli"><a class="el" href="classdw_1_1Table.html" title="A Widget for rendering tables. ">dw::Table</a> has been rewritten.</p>
<p class="endli"></p>
</li>
<li>
<p class="startli">Instead of border_spacing in the old DwStyle, there are two attributes, <a class="el" href="classdw_1_1core_1_1style_1_1StyleAttrs.html#a5865194add47d79910d2e2b5191ab0b9">dw::core::style::Style::hBorderSpacing</a> and <a class="el" href="classdw_1_1core_1_1style_1_1StyleAttrs.html#a0b1c442c655fec5e644c83120afa1798">dw::core::style::Style::vBorderSpacing</a>, since CSS allowes to specify two values. Without CSS, both attributes should have the same value.</p>
<p class="endli"></p>
</li>
<li>
<p class="startli">Images are handled differently, see <a class="el" href="dw-images-and-backgrounds.html">Images and Backgrounds in Dw</a>.</p>
<p class="endli"></p>
</li>
<li>
<p class="startli">Embedded UI widgets (formerly GtkWidget's) are handled differently, see <a class="el" href="namespacedw_1_1core_1_1ui.html" title="Anything related to embedded UI widgets is defined here. ">dw::core::ui</a>.</p>
<p class="endli"></p>
</li>
<li>
DwButton has been removed, instead, embedded UI widgets are used. See <a class="el" href="namespacedw_1_1core_1_1ui.html" title="Anything related to embedded UI widgets is defined here. ">dw::core::ui</a> and <a class="el" href="classdw_1_1core_1_1ui_1_1ComplexButtonResource.html">dw::core::ui::ComplexButtonResource</a>. </li>
</ul>
<p>Dw is now written C++, the transition should be obvious. All "Dw" prefixes have been removed, instead, namespaces are used now:</p>
<ul>
<li>
<a class="el" href="namespacedw_1_1core.html" title="The core of Dw is defined in this namespace. ">dw::core</a> contains the core, </li>
<li>
<a class="el" href="namespacedw_1_1core_1_1style.html" title="Anything related to Dillo Widget styles is defined here. ">dw::core::style</a> styles, </li>
<li>
<a class="el" href="namespacedw_1_1core_1_1ui.html" title="Anything related to embedded UI widgets is defined here. ">dw::core::ui</a> embedded UI resources, </li>
<li>
<a class="el" href="namespacedw_1_1fltk.html" title="This namespace contains FLTK implementations of Dw interfaces. ">dw::fltk</a> classes related to FLTK, and </li>
<li>
<a class="el" href="namespacedw.html" title="Dw is in this namespace, or sub namespaces of this one. ">dw</a> the widgets. </li>
</ul>
