Since: S60 ?S60_version

Parameters

const IfId & aType

The type id of the queried interface.

[pure virtual]

Sets the direction of the flow.

Parameters

enum flowDirection aDirection

Flow direction.

setMode(int)

void

setMode

Member Enumerations Documentation

Enum flowDirection

Flow directions.

Enumerators

EFlowHorizontal	Flow horizontally. System wide layout mirroring is considered to determine whether visuals are layed from left to right or from right to left.
EFlowVertical	Flow vertically.

Enum flowModeFlags

Mode flags that specify how the flow is laid out.

Enumerators

EFlowModeCenterPerpendicular = 0x1	Center the children perpendicular to the flow direction. For example, if the flow direction is horizontal (left->right) this flag will center the children vertically along the flow.
EFlowModeFitPerpendicular = 0x2	Fit the children perpendicular to the flow direction. For example, if the flow direction is horizontal, the children will be vertically resized to fit the layout's rectangle.
