Summary

Sets the current scale mode for the specified cell or sub-cell.

Syntax

#include "ltivw.h"

L_LTIVW_API L_INT EXT_FUNCTION L_DispContainerSetCellScaleMode(hCellWnd, nSubCellIndex,, uScaleMode,uFlags)

Parameters

L_HWND hCellWnd

A handle to the window that represents the cell on which the function's effect will be applied.

L_INT 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.

L_UINT 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 default 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 boundaries.
CONTAINER_SCALEMODE_FITHEIGHT [0x00000003] The image height will fit to the image boundaries.

L_UINT uFlags

Reserved for future use. Pass 0.

Returns

Value Meaning
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.
