L_LTIVW_API L_INT EXT_FUNCTION L_DispContainerSetCellScale(hCon, nCellIndex, nSubCellIndex, dScale, uFlags)

HDISPCONTAINER hCon;

/* handle to the container */

L_INT nCellIndex;

/* index of a cell */

L_INT nSubCellIndex;

/* index into the image list attached to the cell */

L_DOUBLE dScale;

/* scale value */

L_UINT uFlags;

/* reserved for future use */

Sets the current scale value of the specified cell or sub-cell.

Parameter

Description

hCon

Handle to the container.

nCellIndex

A zero-based index of the cell that contains the sub-cell, which is having its scale value set. Pass -1 to set the scale value of the specified sub-cell for all cells managed by the container. Pass -2 to set the scale value of the specified sub-cell for the selected cells managed by the container.

nSubCellIndex

A zero-based index into the image list attached to the cell specified in nCellIndex. This image will be scaled. Pass -1 to apply this effect on all sub-cells. Pass -2 to apply this effect on the selected sub-cell.

dScale

Value that represent the new scale value to be set.

uFlags

Reserved for future use. Pass 0.

Returns

SUCCESS

The function was successful.

< 1

An error occurred. Refer to Return Codes.

Comments

Currently, there are two ways to fit an image to a cell. One is by setting the bIsFit value of DISPCELLPROPERTIES structure to true (also remembering to set the corresponding uMask value), and then sending this structure to L_DispContainerSetCellProperties. The other method is by using L_DispContainerGetCellScale and L_DispContainerSetCellScale. In order to be able to use these functions make sure that bIsFit is set to FALSE.
