Enumeration EChangeFlagsConst

actual state changed (contained objects, object options, etc) only set if the respective object is non-ephemeral

set if the object that triggered a change is ephemeral (e.g. a generator, or a generated tool) basically if this flag is set, the output of serialize will NOT change

displayed data changed

the primary error of an object changed e.g. a toolgenerator finished loading and added an error

the errors of an object changed if the previous flag is set, this one will also always be set; but not vice versa e.g. an object that already had an error encountered a second one

loading state of an object changed e.g. a toolgenerator started or finished loading

no changes

changes to the object tree e.g. an object is added or removed from the object tree, or moved within the object tree

available options of an object changed e.g. new options are available, options were removed, attributes of an option changed NOTE = this is NOT about the values of options; those are handled by the CONFIG flag

viewport configuration changed e.g. the range of the visible data was adjusted because the user scrolled manually, or the zoom function was called, or the configuration of a scale changed, etc

set if the viewport ratio changed if the complete controller is resized (controller.set('height',x) all contained charts are proportionally resized as well; in this case their "size ratios" stay the same however, if only one or two charts were resized (manually by the user, or by calling chart.set('height', x), the ratios change; the event will only be set in these cases

set if the viewport size changed e.g. if the complete controller along with all charts was resized, or if only individual charts were resized
