AcopChooser

Acop Chooser Example	Use the ACOP Chooser for selecting a new target link and applying the selection to other ACOP components. The ACOP Chooser is a GUI component but itself offers no automatic display updates. Instead the user browses and selects among the configured target address options at runtime and his selection is then applied to the target list of ACOP components. As such its Acop.Transport properties are a significantly reduced set of the general options and there is no AddressEditor available for the modal setting of Link properties. In fact the selection at design time of the Link properties serves only specify the chooser ComboBox options at runtime.
Acop Chooser display Properties	ApplyContext if true true: apply the chosen Context to targets ApplyDevice if true true: apply the chosen Device to targets ApplyProperty if true true: apply the chosen Property to targets ApplyServer if true true: apply the chosen Server to targets ApplyTo opens a target component chooser editor which can be used to specify a list of ACOP components which should receive the LinkAddress and LinkProperty reassignment ApplyWhen specifies when to apply the selected LinkAddress and LinkProperty to the target list. ApplyButtonOnly (default) SelectionChanges ContextMenuOnly ChooseContexts if true display and allow Context browsing in the address chooser ChooseDevices if true display and allow Device browsing in the address chooser ChooseProperties if true display and allow Property browsing in the address chooser ChooserStyle provides the combo box dropdown style ChooseServer if true display and allow Server browsing in the address chooser Description specifies label for the address chooser (if ShowHeader = true). FilterContexts provides a filter string (regular expression) to use for filtering Context combo box items FilterDevices provides a filter string (regular expression) to use for filtering Device combo box items FilterProperties provides a filter string (regular expression) to use for filtering Property combo box items FilterServer provides a filter string (regular expression) to use for filtering Server combo box items HighlightBackColor specifies highlighted backcolor of items in a chooser combo box HighlightFilter provides a filter string (regular expression) to use for highlighting combo box items HighlightForeColor specifies highlighted forecolor of items in a chooser combo box ItemBackColor specifies backcolor of items in a chooser combo box ItemForeColor specifies forecolor of items in a chooser combo box ShowHeader if true shows description and apply button
Acop Chooser transport properties	ApplyEventOrder (exclusive, before, after) determines the call order of a user supplied addressUpdate delegate exclusive : only the user supplied delegate will be used (default) before : the user supplied addressUpdate delegate will be called prior to applying the address selection to the target list after : the user supplied addressUpdate delegate will be called following the application of the address selection to the target list LinkAddress specifies the control system endpoint to which the data link is to be attached. This value is composed of the LinkContext, LinkServer, and LinkDevice properties with separator = "/". An ACOP transport plug which makes use of another separator (e.g. channel access) should be prepared to map such address to and from the ACOP address space. LinkContext is the top most hierarchical element of the LinkAddress, identifying, e.g. the specific facility. LinkDevice is the bottom most hierarchical element of the LinkAddress, indentifying e.g. a specific location or device instance. LinkProperty specifies the target property of the LinkAddress which is to return data to the component. LinkProtocol specifies the transport protocol (and hence which transport plug) to make use of when acquiring the given LinkAddress. LinkServer is the middle hierarchical element of the LinkAddress, indentifying e.g. a specific host process. LinkSubSystem specifies an additional browsing element to help reduce the number of LinkServer elements shown in the browsing combo boxes.
