Expression for Computing the Visibility

Expression for computing the visibility of the form page.

If the visibility of the form page is evaluated to false, then inplace editing with the “F2 key” is not allowed for the properties on the form page, this also affects the properties that are shown as columns in the detail view of the list.

Explanation:
Defines an app.ducx expression that computes the visiblity of a form page (see also formpagevisibleexpr).

Name

Description

::root

contains the object the expression is evaluated for. ::root is identical to cooobj.

::isvalue

contains true if the form is used for displaying values (edit mode or read-only mode) opposed to query mode (see valuetype in ApplicationView).

::isedit

contains true if the form is in edit mode opposed to read-only mode (see edittype in ApplicationView). ::isedit is only valid if ::isvalue is true.

::iseditcommon

contains true if the form is used to edit common properties of multiple objects. ::iseditcommon is only valid if ::isvalue is true. In this case ::root/cooobj refer to the first object of the selection.

::isdashboard

see ::iscalcwidget

::iscalcwidget

::isdashboard and ::iscalcwidget are used to determine whether a dashboard will be visible or not:
First, the expression is called to determine if the page should be displayed in the dashboard.
In that case the global scope contains these values:
::isdashboard == false
::iscalcwidget == true
After that, the pages for the dashboard widgets itself are calculated:
::isdashboard == true
::iscalcwidget == true
When the page is displayed in explore mode, the global scope contains:
::isdashboard == false
::iscalcwidget == false

::iscalccelledit

contains true if the expression is evaluated to determine the page for editing in a cell (F2).

::issingleattribute

contains true if the expression is evaluated to determine whether the page in displayed in single attribute mode, i. e. when all other properties of a form page are hidden. Single attribute mode is used to edit a value like an aggregate or a list in a form initialized by editing in a cell (F2) or when showing a zoomed list by selecting "Show detail" on an overview page.

::container

contains the form object respectively the formpage object.

::context
