MyGetDialog

Color picker-defined subroutine that handles a kGetDialog request.

If you create a color picker, it must respond to the kGetDialog request code. The Color Picker Manager sends this code to obtain the custom dialog box for your color picker, in case your color picker uses a custom dialog box. A color picker responds to the kGetDialog request code by calling a color picker-defined subroutine (for example, MyGetDialog) to handle the request.

pascal DialogPtr MyGetDialog (PickerStorageHndl storage);

storage

A handle to your color picker's global data.

DISCUSSION

If your color picker uses its own dialog box, your MyGetDialog function should return a pointer to this dialog box as its function result. If your color picker does not use a color picker-owned dialog box, your MyGetDialog function should return nil.
