LDialogImageEffect::DoModalAddBitmaps
#include "ltwrappr.h"
virtual L_INT LDialogImageEffect::DoModalAddBitmaps(hWndOwner)
|
HWND hWndOwner; |
/* handle of the window which owns the dialog */ |
Displays the Add Bitmaps dialog box, and gets the options for LBitmapBase::Add.
|
Parameter |
Description |
|
hWndOwner |
Handle of the window which owns the dialog. |
Returns
|
SUCCESS_DLG_OK |
The "OK" button was pressed, and the dialog exited successfully. |
|
SUCCESS_DLG_CANCEL |
The "Cancel" button was pressed, and the dialog exited successfully. |
|
< 1 |
An error occurred. Refer to Return Codes. |
Comments
LDialogImageEffect::SetAddBitmapsParams must be called before using this function to set the initial values for the dialog. You can get the updated ADDBITMAPSDLGPARAMS with the values entered by the user through the dialog by using LDialogImageEffect::GetAddBitmapsParams.
