Parameter |
Description |
hCellWnd |
A handle to the window that represents the cell on which the function's effect will be applied. |
nSubCellIndex |
A zero-based index into the image list attached to the cell specified in nCellIndex. The scale for this sub-cell will be retrieved. This sub-cell scale will be retrieved. Pass -2 to retrieve the scale of the selected sub-cell. |
pdScale |
Address of the variable to be updated with the scale value. |
uFlags |
Reserved for future use. Pass 0. |
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Currently, there are two ways to fit an image to a cell. One is by setting the bIsFit value of the DISPCELLPROPERTIES structure to true (also remembering to set the corresponding uMask value), and then send this structure to the function L_DispContainerSetCellProperties. The other method is by using the L_DispContainerGetCellScale and L_DispContainerSetCellScale functions. If using these make sure that bIsFit is set to FALSE.
To set the scale of a cell or sub-cell call L_DispContainerSetCellScale, and to set the properties of the scale action use the L_DispContainerSetActionProperties function. To retrieve the properties of the scale action use the L_DispContainerGetActionProperties function. To set the scale mode of a cell or sub-cell call the L_DispContainerSetCellScaleMode function and to get it call L_DispContainerGetCellScaleMode.
