Technical Q&A TB58 - Styled custom dialog items under Navigation Services (11-January-99) Q: How do we customize the font characteristics of custom items in a NavPutFile dialog? We are adding custom dialog elements using the NavCustomControl call and passing the kNavCtlAddControlList constant and a 'DITL' handle. Unfortunately, we do not seem to be able to set the font size or number for the custom items. We have tried both 'ictb' and 'dftb' resources, but Navigation Services seems to ignore all these. What is the simplest way to customize the font characteristics of custom items in a NavPutFile dialog? We would prefer if this could be done in a 'dftb' or 'ictb' resource, but do not want to end up parsing this information by ourselves. A: Indeed, Nav Services does not honor 'ictb' or 'dftb' resources. This is because it only knows about dialog item list handles, and a dialog item list handle does not contain the resource ID of an 'ictb' or 'dftb' resource. If you want styled items in your Nav customization area, you will need to get the control handles of the items which interest you, create and initialize a ControlFontStyleRec, and pass the control handle and the ControlFontStyleRec to SetControlData along with an appropriate tag constant such as kControlFontStyleTag. It is not necessary to parse the 'ictb' or 'dftb' information yourself, because you can use a hard-coded ControlFontStyleRec without causing localization problems, but it so happens that ControlFontStyleRec closely resembles the format of the items in a 'dftb' resource, so you may want to go that route.
