LImageViewer::GetBounds
#include "ltwrappr.h"
L_INT LImageViewer::GetBounds (lpRect, uFlags);
RECT * lpRect; |
/* pointer to a structure */ |
L_UINT uFlags; |
/* reserved for future use */ |
Gets the bounding rectangle for the container. This function is available only in the Medical Imaging Suite toolkits.
Parameter |
Description |
lpRect |
A pointer to a RECT structure to be updated with the bounding rectangle of the container. |
uFlags |
Reserved for future use. Pass 0. |
Returns
SUCCESS |
The function was successful. |
< 1 |
An error occurred. Refer to Return Codes. |
Comments
The coordinates of lpRect are relative to the parent window coordinates. If the container window has no parent, the coordinates will be relative to the screen coordinates.
To set the bounding rectangle for the container, call LImageViewer::SetBounds.

Example
This function determines whether the container's client area is different from its parent's.
