/** \page dw-changes Changes to the GTK+-based Release Version
|
|
|
|
<h2>Changes in Dw</h2>
|
|
|
|
Related to the FLTK port, there have been many changes, this is a
|
|
(hopefully complete) list:
|
|
|
|
<ul>
|
|
<li> Rendering abstraction, read \ref dw-overview and \ref dw-layout-views
|
|
for details. Some important changes:
|
|
|
|
<ul>
|
|
<li> The underlying platform (e.g. the UI toolkit) is fully abstract,
|
|
there are several platform independent structures replacing
|
|
GTK+ structures, e.g. dw::core::Event.
|
|
|
|
<li> The central class managing the widget tree is not anymore
|
|
GtkDwViewport, but dw::core::Layout.
|
|
|
|
<li> Drawing is done via dw::core::View, a pointer is passed to
|
|
dw::core::Widget::draw.
|
|
|
|
<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
|
|
\ref dw-layout-views).
|
|
</ul>
|
|
|
|
<li> Cursors have been moved to dw::core::style, see
|
|
dw::core::style::Style::cursor. dw::core::Widget::setCursor is now
|
|
protected (and so only called by widget implementations).
|
|
|
|
<li> World coordinates are now called canvas coordinates.
|
|
|
|
<li> There is now a distinction between dw::core::style::StyleAttrs and
|
|
dw::core::style::Style.
|
|
|
|
<li> 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 (dw::core::Widget::iterator,
|
|
dw::core::Iterator).
|
|
|
|
<li> DwPage is now called dw::Textblock, and DwAlignedPage
|
|
dw::AlignedTextblock.
|
|
|
|
<li> dw::Textblock, all sub classes of it, and dw::Table do not read
|
|
"limit_text_width" from the preferences, but get it as an argument.
|
|
(May change again.)
|
|
|
|
<li> dw::Table has been rewritten.
|
|
|
|
<li> Instead of border_spacing in the old DwStyle, there are two attributes,
|
|
dw::core::style::Style::hBorderSpacing and
|
|
dw::core::style::Style::vBorderSpacing, since CSS allows to specify
|
|
two values. Without CSS, both attributes should have the same value.
|
|
|
|
<li> Images are handled differently, see \ref dw-images-and-backgrounds.
|
|
|
|
<li> Embedded UI widgets (formerly GtkWidget's) are handled differently,
|
|
see dw::core::ui.
|
|
|
|
<li> DwButton has been removed, instead, embedded UI widgets are used. See
|
|
dw::core::ui and dw::core::ui::ComplexButtonResource.
|
|
</ul>
|
|
|
|
Dw is now written C++, the transition should be obvious. All "Dw"
|
|
prefixes have been removed, instead, namespaces are used now:
|
|
|
|
<ul>
|
|
<li>dw::core contains the core,
|
|
<li>dw::core::style styles,
|
|
<li>dw::core::ui embedded UI resources,
|
|
<li>dw::fltk classes related to FLTK, and
|
|
<li>::dw the widgets.
|
|
</ul>
