Creating Pop-Up Windows in Flex/AIR
Pop-ups are a vital part of any application. In this post, we are going to look into how a popup window can be designed in FLEX/AIR.
PopUpManager class is the one used to create new top-level windows and can be used to place above all the visible windows (making it a popUp). You can remove popUps as well using this class.
We can make these windows modal as well.
We can create a popUp using createPopUp method.
public static createPopUp(parent:DisplayObject, class:Class, modal:Boolean = false):IFlexDisplayObject
Here parent is the window over which the popup is going to appear, class is the reference to the custom MXML component which is going to act as pop-up, modal represents the Boolean value to decide on whether the popup is going to be modal or not.
Skinning Flex/AIR Components
Skinning is like changin the look of the components. To skin Flex components, we can use either Bitmaps or swfs or programmatically we can skin.
In this post we will be looking into skinning Flex Components graphically i.e. using Bitmap images and using SWFs. Using skins we can define the whole appearance, different states of the components.
For example, we will see skinning a button now. We can give whole new look to different states of button like down, up, over etc.
