The WPPrvFrm does not appear to honor the DisabledButtons property. I looked at the code and it does not do anything with those settings, nor do I see the actual button objects, only the OnClick events for them. So I'm not sure how to modify the form to hide the save, print etc buttons.
I see, there was something planned ....
This code in Execute will fix the problem.
dia.ToolBar.sel_ActionIcons := [SelSave, SelPrint, SelPrintSetup];
if wpprvPrint in FDisabledButtons then
dia.ToolBar.sel_ActionIcons := dia.ToolBar.sel_ActionIcons - [SelPrint];
if wpprvPrintDialog in FDisabledButtons then
dia.ToolBar.sel_ActionIcons := dia.ToolBar.sel_ActionIcons - [SelPrintSetup];
if wpprvSaveAs in FDisabledButtons then
dia.ToolBar.sel_ActionIcons := dia.ToolBar.sel_ActionIcons - [SelSave];
