L_LTIVW_API L_INT EXT_FUNCTION L_DispContainerSetCellScaleMode(hCon, nCellIndex, nSubCellIndex,, uScaleMode,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_UINT uScaleMode;

Sets the current scale mode for 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 mode set. Pass -1 to set the scale mode for the sub-cell with nSubCellIndex for all cells managed by the container. Pass -2 to set the scale mode for the sub-cell with nSubCellIndex for the selected cells managed by the container.

nSubCellIndex

A zero-based index into the image list attached to the cell specified in nCellIndex. The sub-cell with nSubCellIndex, will have its scale mode set. Pass -2 to set the scale mode of the selected sub-cell.

uScaleMode

Flag that indicates the type of the scale. Possible values are:

 

Value

Meaning

 

CONTAINER_SCALEMODE_NORMAL

[0x00000000] no scale mode applied. This is the defualt value.

 

CONTAINER_SCALEMODE_FIT

[0x00000001] The image will fit to the sub-cell boundaries.

 

CONTAINER_SCALEMODE_FITWIDTH

[0x00000002] The image width will fit to the sub-cell boundaires.

 

CONTAINER_SCALEMODE_FITHEIGHT

[0x00000003] The image height will fit to the image boundareis.

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.
