Gets a list of themes shown on a layer or selection set.
theme_names = GetDisplayedThemes(string lyr_set_name)
| Argument | Contents |
|---|---|
| lyr_set_name | Name of the layer or selection set |
An array of theme name strings.
If lyr_set_name is null then GetDisplayedThemes() returns an array of theme name strings for the working layer in the working map.
The lyr_set_name can include a map specification, as in "MyMap|States|Selection"; if a map specification is not included, the working map is used.
If no themes are being shown, the return value is null.
GetDisplayedThemes() does not return all themes defined on a layer, only those on the layer in the working map.
Use GetThemes() to obtain a list of all themes defined on a layer.
thms = GetDisplayedThemes("States|")
for i = 1 to thms.length do
HideTheme("States|", thms[i])
end
