Theme (PRIM_THM)
Styles to be used as a base for the application appearance
Ancestors - Object (PRIM_OBJT)
Details
A Theme is a collection of DrawStyles used to configure the appearance and behavior of controls and features of an application. It is akin to a typical CSS file defined for a web page, providing a central point in which to define the vast majority, if not all, of the styles required in an application. A range of predefined System Themes is shipped with the product providing a base set of colors based on the Google Material Design guidelines. The default theme for Web Pages is 2015Gray. These themes may be entirely adequate for many applications and can be applied with little more than a click or two in the IDE by selecting the required theme from the ribbon. Default themes can be extended by creating a user Themes. A different BaseTheme can be adopted as required, and the default DrawStyles can be modified to implement whatever color scheme is required. In addition, DrawStyles can be created to suit whatever formatting option is desired. Themes are tightly integrated with the IDE. When a Theme is applied to a Web Page for example, the controls and features of the application will immediately respond appearing as they would at runtime. Controls subsequently added to the page will also appear correctly. While a Web Page has the Theme specified, individual reusable parts are designed in isolation with no knowledge of the Theme to be used at run time. To simplify the design process and to bring it in to line with designing a page, the IDE supports a Design Theme. By specifying a design Theme, the IDE is given a context, allowing reusable parts to appear correctly. The Color Palette of a Theme can be modified, but with the exception of the Text, Border and Line colors, it is recommended that new DrawStyles be created.
