We have two userobjects uo_fms_picturebutton and uo_fms_picturebutton2 which are inherited from the standard picturebutton control. 4 of these are placed on our ancestor window object w_genapp_base, 2 of each type called cb_1,cb_2,cb_3_cb_4. We would like to have different theme properties specified for each of these picturebutton control types, e.g. uo_fms_picturebutton is always white and uo_fms_picturebutton2 is always blue. I have a standard themes file with a picturebutton entry and a custom themes file but i am not clear how I specify the ancestor object nodes in the customs theme file. I cannot get anything to work. Has anyone had experience of overriding themes for ancestor standard visual objects?
