You typically define a SplashScreenImage class
in an MXML file.
Use the SplahsScreenImageSource class to define the different
image choices and corresponding device configurations.
You then set the application's splashScreenImage
property to the name of the SplashScreenImage MXML component.
The procedure for determining the best match of an SplahsScreenImageSource definition to a mobile device is as follows:
- Determine all of the SplashScreenImageSource definitions
that match the settings of the mobile device.
A match occurs when:
- The SplashScreenImageSource definition does not have that setting explicitly defined.
For example, no setting for the
dpiproperty matches any device's DPI. - For the
dpioraspectRatioproperty, the property must exactly match the corresponding setting of the mobile device. - For the
minResolutionproperty, the property matches a setting on the device when the larger of theStage.stageWidthandStage.stageHeightproperties is equal to or greater thanminResolution.
- The SplashScreenImageSource definition does not have that setting explicitly defined.
For example, no setting for the
- If there's more than one SplashScreenImageSource definition that matches the device then:
- Choose the one with largest number of explicit settings.
For example, a SplashScreenImageSource definition that specifies both the
dpiandaspectRatioproperties is a better match than one that only species thedpiproperty. - If there is still more than one match, choose the one with highest
minResolutionvalue. - If there is still more than one match, choose the first one defined in the component.
- Choose the one with largest number of explicit settings.
For example, a SplashScreenImageSource definition that specifies both the
Note: This class cannot be set inline in the MXML of the application.
You must define it in a separate MXML file and reference it by using the
application's splashScreenImage property.

SplashScreenImage.
Typically you do not call this method directly.
Instead, you add SplashScreenImageSource definitions
inline in the MXML file of the SplashScreenImage component.

Returns the Class of the SplashScreenImageSource that best matches the specified device parameters.
You do not call this method directly; it is called internally by Flex.
Override this method in a SplashScreenImage component if you want to override the default Flex logic of picking the best matching SplashScreenImageSource instance.
Parametreler
aspectRatio:String — Either flash.display.StageAspectRatio.PORTRAIT or
flash.display.StageAspectRatio.LANDSCAPE, whichever is greater.
| |
dpi:Number — The DPI of the mobile device.
| |
resolution:Number — The resolution of the mobile device's bigger dimension, in pixels.
|
Class — The Class for the image to be displayed as a splash screen image.
