Member Functions Documentation

Flip()

TBool

Flip

(

)

const [inline]

The method gets the flip attribute of the surface stored in the object of this class. If the flip was not set, the value returned will be EFalse.

Post-condition: If the instance of TSurfaceConfiguration is too small, the default EFalse setting will be returned.

SetFlip(TBool)

TInt

SetFlip

(

TBool

aFlip

)

[inline]

This method sets the flip attribute to the surface. The default value is EFalse.

Post-condition: The flip attribute is updated in the object of this class. This does not imply that the flip is set for the surface content. The SetBackgroundSurface API must be called passing an object of this class as parameter to get the desired effect.

Parameters

TBool aFlip

When ETrue enalbes flip in the x-axis

SupportsAllMembers()

TBool

SupportsAllMembers

(

)

[inline]

This method identifies which attributes are available to use.

Generally, any version of the server will accept any version of TSurfaceConfiguration , ignoring newer version attributes it does not recognize and substituting defaults for attributes not present in older version.

However, by using this method in conjunction with GetBackgroundSurface() the intelligent client can identify which blocks of attributes are actually present and supported after a call to GetBackgroundSurface, avoiding preparing complex attributes, or reducing user-interface control gadgets.
