Another thing is that it seems like the new rpreview will NOT take into consideration when the app is themed to add the new buttons...?
It is so with both new and old rpreviews. There is no change in this present version.
If the application has a main window and the main window has buttonbar and the buttonbar has l2007 style OR IsAppThemed() is false, RPreview uses FWH's own TBar as the buttonbar. Otherwise it uses Rebar. Since providing interface for Rebar for the additional buttons was a bit complex, it was not provided in this case even originally.
In other words this interface of providing additional buttons was made available where IsAppThemed() is .f. OR the application has main window with a buttonbar with l2007 style, whether or not the app is themed.
Notice the text "factor" overlaps the exit button. Can someone help?
This is noticed. Soon a fix will be made available.
