TAknWindowComponentLayout Class Reference

class TAknWindowComponentLayout

A window component structure from scalable layout.

The data members of this class have the following invariants which must be preserved in any methods of this class.

il + iW + ir = parentRect.Width() it + iH + ib = parentRect.Height()

The data format of the data members are as follows: (AknLayoutUtils knows this) any of il,iW,ir, it,iH,ib may be one of the following 1) coordinate value 2) ELayoutEmpty 3) ELayoutP - value

subtract two layout lines relative to the same parent rectangle

Minus combines two layout lines in such way that a) the result is aLine with it's parent rectangle changed b) aLine and aParentDiff's parent rectangles becomes the same; and result's parent rectangle is calculated to be aParentDiff's child rectangle.

Parameters

TAknWindowComponentLayout aLinethe inner rect

IMPORT_C TAknWindowComponentLayoutSiblingAsChild(TAknWindowComponentLayoutaSiblingTreatedAsParent,
TAknWindowComponentLayoutaSiblingTreatedAsChild
)[static]

Treat two layout lines as if one is a child of the other. The two layouts must have the same parent. They must also have the same pattern of absolute, ElayoutEmptys and Parent relative measurements, both vertically and horizontally.

a layout representing aSiblingTreated as child, relative to aSiblingTreatedAsParent

Parameters

TAknWindowComponentLayout aSiblingTreatedAsParent
TAknWindowComponentLayout aSiblingTreatedAsChild

Split(TAknWindowComponentLayout, TInt)

IMPORT_C TAknWindowComponentLayoutSplit(TAknWindowComponentLayoutaLine,

This method splits parent rectangle to one of the 9 pieces based on aLine.

aValue is one of the numbers: 0 1 2 3 4 5 6 7 8 This is highly related to "frames" in skins. This allows us to generate a skin frame definition from a single TAknWindowComponentLayout.
