Override to augment dialog-box initialization.
CommentsThe base implementation is not called if a handler exists. This can be done via PyCDialog::OnInitDialog.
Return ValueSpecifies whether the application has set the input focus to one of the controls in the dialog box. If OnInitDialog returns nonzero, Windows sets the input focus to the first control in the dialog box. The application can return 0/None only if it has explicitly set the input focus to one of the controls in the dialog box.
