» Hover Help Plug-in Guide # Hover Help Preferences This section describes the preferences panel that you can use to configure and change the Developer Library plug-ins used by Hover Help. Select Window > Preferences > Carbide.c++ > Hover Help to open the Hover Help preference panel. With the preferences panel, you can: Let Hover Help automatically choose the right Developer Library. Select a Developer Library using the drop-down box. Deactivate Hover Help. Restore the default Hover Help configuration. Apply, confirm or cancel the changes. ## Automatically select latest Developer Library Checkbox When you check the "Automatically select latest Developer Library" checkbox, the Developer Library is automatically selected for you. The name of the selected library is displayed in the grayed field. If you want to select a particular Developer Library, follow these steps. The right Developer Library is chosen using these heuristics: Choose by audience and license of the Developer Library. Platform development has precedence over public development. For example: "Developer Library rel1 (Platform) (date1)" will be chosen rather than "Developer Library rel2 (Public) (date2)". Then choose by latest publication date of the Developer Library. For example: "Developer Library rel1 (Platform) (21/03/2009)" will be chosen rather than "Developer Library rel1 (Platform) (20/02/2009)". ## Developer Libraries Drop-Down Box The selected Developer Library is shown in the drop-down box. To change the Developer Library, first uncheck the "Automatically select latest Developer Library" checkbox. Then select a Developer Library from the drop-down box list. To add a new Developer Library, follow these steps. ## Deactivate Hovering Checkbox Checking the `Deactivate Hovering` checkbox disables Hover Help, and unchecking the checkbox reactivates Hover Help. When you reactivate Hover Help, the "Automatically select latest Developer Library" checkbox is checked. ## Restore Defaults Button If the “Restore Defaults” button is clicked, the "Automatically select latest Developer Library" checkbox is checked, and the "Deactivate Hovering" checkbox is unchecked. ## Apply, OK, Cancel Buttons These buttons have the common Carbide behaviours.
