Porting from v1 to v2

To make the framework toolkit agnostic to support QtQuick and even non-Qt toolkits such as Flutter some API changes were required.
Each component was split into 2, one part lives in core/ and is gui agnostic, while the other part lives in a frontend specific folder, such as qtwidgets/ (or qtquick/).

For example, TitleBar was split into KDDockWidgets::Core::TitleBar and KDDockWidgets::QtWidgets::TitleBar. The former we call it a Controller, while the latter is the View. In the QtWidgets case, a view is a QWidget, while in QtQuick it's a QQuickItem.

The main public API didn't change much, but if you're using private API heavily to achieve advanced customizations then take note of these renamings:

(Assume ::QtQuick:: namespace instead of ::QtWidgets:: if you're on QtQuick).

• Frame was renamed to Group as it represents a tab group
• TabWidget was renamed to Stack
• KDDockWidgets::DefaultWidgetFactory was renamed to KDDockWidgets::QtWidgets::ViewFactory
• The *Widget and *Quick classes dropped the suffix and are namespaced instead:
  • KDDockWidgets::TitleBarWidget -> KDDockWidgets::QtWidgets::TitleBar
  • KDDockWidgets::TitleBarQuick -> KDDockWidgets::QtQuick::TitleBar
  • Same for DropArea, FloatingWindow, TabBar, Group, Stack, MainWindow, DockWidget
• You can include the views for example with #include <kddockwidgets/qtwidgets/views/TitleBar.h>. This is only required if you're customizing the default visuals.
• KDDockWidgets::DefaultWidgetFactory::s_dropIndicatorType is now KDDockWidgets::Core::ViewFactory::s_dropIndicatorType

If some API is missing in the View, try looking in the controller, so, for example, look in KDDockWidgets::Core::TitleBar instead of KDDockWidgets::QtWidgets::TitleBar.

Headers

Views are in kddockwidgets/FRONTEND/views/. Replace FRONTEND with qtwidgets or qtquick.

So for example, if you had:

#include <kddockwidgets/private/widgets/TitleBarWidget_p.h>
#include <kddockwidgets/private/TabWidget_p.h>
#include <kddockwidgets/private/widgets/TabBarWidget_p.h>

You should now have:

#include <kddockwidgets/qtwidgets/views/TitleBar.h>
#include <kddockwidgets/qtwidgets/Stack.h>
#include <kddockwidgets/qtwidgets/views/TabBar.h>
