Attribute " type " the 505th, the indication screen is logical screen or the attribute information of display screen.
Attribute " z-order " the 510th is for the order of determining to arrange a plurality of logical screens along the z axle.Fig. 7 illustrates the configuration of the logical screen on the physical display of combination of value of attribute for logical screen " z-order ".
With reference to Fig. 7, respectively the first logical screen 620 and the second logical screen 630 are mapped to the presumptive area of display screen 610.At length, the first logical screen 620 is displayed on the display screen 610, and the second logical screen 630 and the first logical screen 620 are presented on the display screen with overlapping.In other words, sequentially arrange display screen 610, the first logical screen 620 and the second logical screen 630 along the z direction of principal axis.In this case, the attribute " z-order " that the attribute of the first logical screen 620 " z-order " can the value of being set to 1, the second logical screen 630 can the value of being set to 2.The attribute of the first logical screen 620 and the second logical screen 630 " z-order " can be set to Any Digit or character, as long as they can represent the particular order of arranging the first logical screen 620 and the second logical screen 630 along the z direction of principal axis.
Shown in Fig. 8 A and Fig. 8 B, attribute " viewing area " the 520th is about the information in the display screen zone of logical screen.
Fig. 8 A illustrates the whole zone that logical screen 710 is mapped to display screen 720, and Fig. 8 B illustrates the subregion that logical screen 730 is mapped to display screen 740.
Attribute " viewing area " can comprise specifies logical screen with the information of the two-dimensional coordinate of the predetermined portions of the display screen of mapping, can comprise that perhaps what deviant information and the indication logical screen of specifying the precalculated position on the display screen have departed from from the precalculated position on the display screen.
Attribute " observability " 530 is determined logical screen still invisibly is presented on the display screen visibly.By changing the value of attribute " observability " 530, logical screen is appeared on the display screen or from display screen disappear.
Attribute " relevant display screen " the 540th is about the information of the display screen relevant with logical screen.The logical screen that all has nothing to do with any display screen may not be displayed on the physical display, also is not sent to outside output device.
Attribute " relevant service context " the 550th is about the information of the service context that is connected to logical screen or display screen.The service that is arranged in such service context can be displayed on logical screen or the display screen.
Attribute " output port " the 560th, about the information with the device of output display screen, this device comprises display screen, wire/wireless communication media and various medium.
Can be provided for identifying or changing the interface of the value of attribute as shown in Figure 6.With reference to Fig. 6, this interface can comprise: interface " setting " sets property or logical screen is connected to display screen; Interface " interpolation " adds property value or logical screen is connected to service; Interface " obtains ", the recognition property value; And interface " deletion ", the delete property value.These interfaces can comprise respectively process, function, program or the method for carrying out its function.
For example, method " getDisplayScreen (void) " is returned the display screen relevant with current screen.At length, if current screen is logical screen, then method " getDisplayScreen (void) " is returned relevant display screen.If current screen is display screen, then method " getDisplayScreen (void) " is returned the reference information about current screen.In addition, if current screen is logical screen, but do not have relevant screen, then method " getDisplayScreen (void) " is returned " NULL " value.
According to another example, method " public void setDisplayArea (HScreenRectangle rect) throws SecurityException, IllegalStateException " provide the function that current logical screen is mapped to the presumptive area of relevant display screen.The example that provides as parameter is the class " HScreenRectangle " of bag " org.havi.ui ", and this example has two-dimensional position information.It is processed that the execution of method " SecurityException " and " IllegalStateException " can be used as method " setDisplayScreen (HScreenscreen) " abnormal operation.When current screen is logical screen, or when the part of the display screen relevant with current logical screen can not change owing to the characteristic of host platform, executing method " IllegalStateException ".
According to another example, method " getDisplayArea (void) " is returned the area information of current screen as HScreenRectangle information.If current screen is corresponding to display screen, then method " getDisplayArea (void) " is returned and is had the HScreenRectangle information identical with the value of HScreenRectangle (0,0,1,1).If current screen is logical screen, then method " getDisplayArea (void) " is returned the information about the zone on the display screen that is occupied by current screen.If current screen is logical screen but all has nothing to do with any display screen, then method " getDisplayArea (void) " is returned " NULL " value.
Run through following, describe some term and be used to represent special interface.Yet, it should be appreciated by those skilled in the art that the name of specific function is just in order to indicate its function.The detailed description of this exemplary embodiment is not in order to distinguish the different function of title, but in order to distinguish function.
