Note on the properties window that you can easily assign an 'Action' to the button from the drop down list, in this instance 'Previous Record' was chosen. 'pbPreviousCourseStudent' is highlighted in yellow in the properties window with a green arrow pointing to the relevent button. In the Navigator you can see that 'dsCoursesOverview' has the buttons 'pbNextCourse' and 'pbPreviousCourse' attached to it and further to that there is a sub datasource (linked to dsCourseOverview via properties link master and link child fields) called 'dsCourseStudent' that has the buttons 'pbNextCourseStudent' and 'pbPreviousCourseStudent' If you look at the 'Form Navigator' panel, you will see that various buttons have been attached to various datasources, this is easiest accomplished by clicking the datasource prior to drawing the button. These are kinda necessary when building your forms, but you most likely dont want them displayed when your database is in use, so just untick them when using the database. The following database types are read-only types in LibreOffice Base. You can also use LibreOffice Base to connect to external relational databases, such as databases from MySQL or Oracle. The toolbars menu is displayed, showing you that the 'Form Controls', 'Form Design' and 'Standard' toolbars are displayed. LibreOffice Base natively supports some flat file database formats, such as the dBASE format. Above image represents the form in design view.
