Topic group

Indicates whether themes are in use for the application.

Property of

_app object

Description

_app.themeState() returns one of the following values:

• 0 - themes are not available (old OS, or no manifest file, or themes were disabled at the application initialization in another manner).

• 1 - themes are enabled, but with the old theme (the user has chosen the "Windows Classic" theme).

• 2 - themes are enabled and a newer theme is active.

Note:

• With theme states 0 and 1, the controls have the old look and are backward compatible.

• With state 2, some form components may have new colors or their border may have new shape and position.  Therefore, with state 2 some modifications (in dBL code) may be needed.
