General Changes

Widget Filter Box

1. Displaying only icons in the Widget Box: It is now possible for the Widget Box to display icons only. Simply select Icon View from the context menu.
2. Filter for Widget Box: A filter is now provided to quickly locate the widget you need. If you use a particular widget frequently, you can always add it to the scratch pad.
3. Support for QButtonGroup: It is available via the context menu of a selection of QAbstractButton objects.
4. Improved support for item widgets: The item widgets' (e.g., QListWidget, QTableWidget, and QTreeWidget) contents dialogs have been improved. You can now add translation comments and also modify the header properties.

Support for Embedded Design

Comboboxes to Select a Device Profile

It is now possible to specify embedded device profiles, e.g., Style, Font, Screen DPI, resolution, default font, etc., in Preferences. These settings will affect the Form Editor. The profiles will also be visible with Preview.

• QUiLoader -- forms loaded with this class will now react to QEvent::LanguageChange if QUiLoader::setLanguageChangeEnabled() or QUiLoader::isLanguageChangeEnabled() is set to true.
• QDesignerCustomWidgetInterface -- the domXml() function now has new attributes for its <ui> element. These attributes are language and displayname. The language element can be one of the following "", "c++", "jambi". If this element is specified, it must match the language in which Designer is running. Otherwise, this element will not be available. The displayname element represents the name that will be displayed in the Widget Box. Previously this ward hardcoded to be the class name.
• QWizard -- QWizard's page now has a string id attribute that can be used to fill in enumeration values to be used by the uic. However, this attribute has no effect on QUiLoader.
