virtual L_INT LDialogColor::DoModalBrightness(hWndOwner)
Handle of the window which owns the dialog.
LDialogColor::SetBrightnessParams must be called before using this function to set the initial values for the dialog. You can get the updated BRIGHTNESSDLGPARAMS with the values entered by the user through the dialog by using LDialogColor::GetBrightnessParams.
| Value | Meaning |
|---|---|
| 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. |
