Some notes about the things to be careful during the migration of the widgets for qooxdoo 0.8.

• addEventListener() ⇒ addListener()
• HorizontalBoxLayout ⇒ HBox
• VerticalBoxLayout ⇒ VBox
• qx.ui.core.Border ⇒ qx.ui.decoration.Single
• qx.ui.widget.Iframe.getContentDocument() ⇒ qx.ui.widget.Iframe.getDocument()
• createDispatchEvent() ⇒ fireEvent()
• createDispatchDataEvent() ⇒ fireDataEvent()
• qx.event.type.DataEvent ⇒ qx.event.type.Data
• qx.core.Object.dispose() ⇒ qx.core.ObjectRegistry.shutdown()
• getParent() ⇒ getLayoutParent()
• qx.io.Alias ⇒ qx.util.AliasManager
• qx.ui.embed.Iframe.getContentDocument() ⇒ qx.ui.embed.Iframe.getDocument()
• qx.ui.embed.Iframe.getContentWindow() ⇒ qx.ui.embed.Iframe.getWindow()
• qx.ui.basic.Label.setText() ⇒ qx.ui.basic.Label.setContent()
• #embed ⇒ #asset
• qx.application.???._postload() ⇒ qx.application.???.finalize()
• qx.ui.selection.RadioManager ⇒ qx.ui.form.RadioGroup
• beforeAppear ⇒ appear

• border ⇒ decorator
• Layout handling
• edge ⇒ left, top, right, bottom
• User agent handling
  • qx.core.Client.getInstance().getEngine() ⇒ qx.bom.client.Engine.NAME
• Event handling:
  • qx.html.EventRegistration ⇒ qx.event.Manager
  • this.dispatchEvent(new qx.event.type.DataEvent("name", eventData), true) ⇒ this.fireDataEvent("name", eventData)
• mouse capture:
  • setCapture(true) ⇒ capture()
  • setCapture(false) ⇒ releaseCapture()
• getElement ⇒ getContainerElement().getDomElement()
• Layout properties
• _renderRuntimeXXX() ⇒ setUserBounds() or setLayoutProperties({left: 10, top: 10})
• setLeft(12) ⇒ setLayoutProperties({left: 12}) (in Canvas and Basic layouts)
• setTop(12) ⇒ setLayoutProperties({top: 12}) (in Canvas and Basic layouts)
• setRight(12) ⇒ setLayoutProperties({right: 12}) (in Canvas and Basic layouts)
• setBottom(12) ⇒ setLayoutProperties({bottom: 12}) (in Canvas and Basic layouts)
• Tree does not generate a root folder by default anymore
• SplitPane
  • addLeft(), addTop(), addRight(), addBottom() are removed. Use setFirst() and setSecond() to set widgets into the SplitView. The position of first and last is set by the SplitPane's orientation property.
  • getLeftArea(), getTopArea(), getRightArea() and getBottomArea() are removed. Use getFirstArea() and getSecondArea() instead.
• Appearance: Some states were renamed:
  • over ⇒ hovered
  • focus ⇒ focused

• Positions in the appearance
• ClientDocument. Use this.getRoot() in qx.application.Standalone instead.
• qx.util.Mime. Use strings explicitly
• addToDocument(). Use application.getRoot() instead
• qx.ui.SplitPaneKnob: style Splitter and Slider to show a knob
• qx.ui.core.Widget.isMaterialized ⇒ not needed any longer
• qx.ui.core.ClientDocument.isMaterialized ⇒ not needed any longer
• qx.core.Version no longer exists

• qx.io.local.CookieApi missing in 0.8 and 0.8.1 ⇒ Use native cookie handling. Releases 0.8.2 and beyong include (again) cookie handling.
