Starling components in flash feathers Learning notes

Recently in learning Starling, and then feel that it is impossible to write their own components, heard that there are now supporting starling of the feathers components, to take a look at

This seems to be a new, no learning materials, are in English. Some of the notes are as follows:

There are three classes and one interface under the 1.popups package to implement the pop-up layer

2.CalloutPopUpContentManager is relatively simple, the open method directly using Callout.show (content, source) to pop

The 3.Callout control feature is similar to tip. It can pop up a tip with an arrow pointing to the specified displayobject, and you can set its direction. It seems to automatically adjust the position in the range that the stage can display. The Callout.show method is actually called Popupmanager.addpopup () to pop the hint.

4.PopUpManager is under the Feathers.core package. This bag is actually the interface and management class of the specific control

The 5.popupmanager.addpopup method does not need to set the popup display object's parent, as it is directly stage.addchild to the top level

6.VerticalCenteredPopUpContentManager for center eject, its open (Content:displayobject, source:displayobject): Source in the void method is not being used. That means the parent of the pop-up layer is directly stage.

The <aspectRatio>landscape</aspectRatio> in 7.app.xml is to let the application landscape

8.DropDownPopUpContentManager is to eject a layer above or below the specified displayobject. It depends on the y-coordinate of the displayobject to determine whether it is up or down. Similar to the callout. But it's not without arrows.

9.PickerList is equivalent to pulling the selection control. It contains a button and a list, click on the button, popup popup list lets you choose. As for which Popup method, it is set by the current theme.

The LabelField of 10.9.PickerList is used to set the text value of the button with which key of the Dataprovider item

11.9.pickerlist.listproperties. @itemRendererProperties. LabelField = "text"; the text value used to set item in the list is Dataprovider Which key of item

12. Custom list Itemrender to create a new class, inherit from Defaultlistitemrenderer and then This._list.itemrenderertype = Testitemrender;

13. It is necessary to initialize a new topic in main (Game), which will set the list's defaultlistitemrenderer in the theme.

14.featherscontrol.validate will trigger redraw draw

_btn.upskin =new Image (uptexture); normal state

_btn.hoverskin = new Image (downtexture);

_btn.downskin = new Image (uptexture), mouse down
