Theme Properties
Cadcorp SIS Desktop uses named Theme objects to control the display (e.g. Brush, Pen, Symbol of items) and also to annotate items, e.g. with Bar Charts, or Pie Charts,
TIP: See Theme Types available for a complete list of available Themes.
The properties of Theme objects are set and queried using the SIS_OT_THEME
constant and the GetFlt/GetInt/GetStr/GetProperty and SetFlt/SetInt/SetStr/SetProperty methods.
The nObject& argument is not required with SIS_OT_THEME
and should be set to 0. The Theme must first have been loaded using the LoadTheme method or created using one of the Theme creation methods, e.g. CreateBarTheme
Theme Component Properties
Several types of Theme consist of several "components", e.g. blocks in a Bar Charts Theme, slices in a Pie Charts Theme, etc.
Each of these components has its own properties.
Theme component properties are set and queried using the SIS_OT_THEMECOMPONENT
constant and the GetFlt/GetInt/GetStr/GetProperty and SetFlt/SetInt/SetStr/SetProperty methods.
The nObject& argument must be the index of the Theme component being queried or edited. The number of components in a Theme is dependent on the type of Theme.
The Theme must first have been loaded using the LoadTheme method or created using one of the Theme creation methods, e.g. CreateBarTheme.
Note: Theme component indices run from zero to one less than the number of Theme components.
