Activation Window
The Activation Window lets you configure what happens when a
row is activated.
You can display it using the
Activation Window ()
button when the chosen table is selected in the
Control Window's Table List.
A list of suggested Activation Actions is displayed in the top left panel, and if you select one of these its details, including configuration and invocation options and the results of invoking these actions to date, will be shown in the rest of the window. Those actions in the list which are enabled (not greyed-out) and have their checkbox checked will be invoked every time a table row is activated. Unchecked ones can be invoked manually. More description of each of the panels is given below.
The Actions list
lists a number of activation actions that may be appropriate
for the table this window applies to.
Others, including duplicates of ones already listed,
can be added from the Add Action () button
or menu item.
The only reason the full list is not visible by default is to
avoid too much clutter in the window.
Each action has a checkbox; if checked, an attempt will be made to
invoke that action whenever a row is activated (e.g. clicked on).
If the checkbox is not checked, the action can still be invoked
manually for the current row using the
Invoke Selected Action on Current Row (
) or
Invoke Selected Action on All Rows (
) buttons.
If the action name is greyed out, it means that it can't currently
be invoked for some reason, perhaps because it needs more configuration first.
To find out the reason, look in the Status panel,
which should have a helpful message indicating why it's disabled.
The grab handles (
) can be used to re-order items in the
list, though this order doesn't have much effect except visually.
Actions can be removed from the list by selecting them and using the
Remove Current Action (
) button.
The Description panel gives a short description of the behaviour of the currently selected action.
The Configuration panel displays a user interface to configure the details of what the selected action will do. The format depends on the action; see Appendix A.10.1 for details.
The Status panel contains a button (identical to that in the toolbar) that will invoke the currently selected action on the most recently activated row (or the first row, if no row has been activated so far in this table). It may be in one of two states. If the action is sufficiently configured to be used immediately, the button will be enabled, and clicking on it will cause the action to happen immediately, with the result being displayed in the Results panel below. However, if the action cannot be performed for some reason, the button will be greyed out, and some text will explain why it's disabled. Sometimes that means that the configuration in the panel above needs to be adjusted (e.g. some values filled in).
The Results panel
contains a line added every time the currently selected action is invoked,
either by the Invoke buttons
(,
,
,
)
or because a row has been activated elsewhere in the application.
Each line contains four entries:
A Security panel may occasionally also be visible. If you see this, consult Appendix A.10.3 for an explanation.
The following items are available in the toolbar or menus:
