LDialogWeb::DoModalGIFWebTuner
#include "ltwrappr.h"
virtual L_INT LDialogWeb::DoModalGIFWebTuner (hWndOwner)
|
HWND hWndOwner; |
/* handle of the window which owns the dialog*/ |
Displays the GIF Web tuner dialog box, and gets tuning options used by LBitmapBase::ColorRes, LBitmapBase::Fill, LBitmapBase::Save, LBitmapRgn::SetRgnColorRGBRange.
|
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_CLOSE |
The "Close" 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
LDialogWeb::SetGIFWebTunerParams must be called before using this function to sets the initial values for the dialog. You can get the updated GIFWEBTUNERDLGPARAMS with the values entered by the user through the dialog by using LDialogWeb::GetGIFWebTunerParams.
