Part 4: Programming concepts 79 Terminology As already seen, a WINDEV Mobile project (linked to an analysis if necessary) is used to create an application. Before we actually start working with WINDEV Mobile, let’s go back to the vocabulary used in WINDEV Mobile. Indeed, several terms are specific to WINDEV Mobile and they may differ from the ones used in other tools. The following terms are used in the analysis : • Data file : The analysis is used to describe the structure of database files. A "Data file" corresponds to a "table" in some databases. In WINDEV Mobile, " Table " represents a graphic object used to view the content of a data file in a table and/or to enter rows. A table can be used to type the order details for example. • Record : A record is sometimes called row. A data file record corresponds to all items defined for the data file. • Item : In the analysis, an item represents a section of a data file. All items found in a data file are used to define the structure of a record. • Key/Index : With WEBDEV Mobile and its HFSQL database, the concept of index is linked to the concept of key. The concept of key is part of the item characteristics. The keys are used to improve the speed for accessing data and to simplify the browse operations performed on the data files. In WINDEV Mobile, if a HFSQL data file includes several key items, a single index file will be created at run time. The following terms are used in the windows and reports : • Window : Windows are used to display or type information on the screen. Windows are also called "Screens" or "Dialog boxes". The user can directly act on the windows via controls, buttons, ... • Report : Reports are used to get a custom view of information. This information can come from the database, from text files, from controls found in the windows, ... Reports can be generated in PDF in mobile applications. • Control : "Control" is the term used to identify the different graphic objects displayed in a window or report. • Skin template : The skin template is used define the application style: visual appearance of windows, buttons, controls, ... • Style : The style groups the graphic characteristics of an element: background image, border, font, ... The styles of different elements found in the interface of a WINDEV Mobile application are grouped in a style sheet.
