Object PmaDataTable (Data Table)

Description:
See: PmaDataTable - Deatiled object description

The object serves for the definition of the data table (2-dimensional array). Data in this table are ordered into columns and rows. It is the analogy of the database table. A data type and a column name can be defined for the column.

No other Pma objects can be created in this object.
This object can be created in objects: PmaRoot, PmaFolder, PmaPrototype. Multiple objects of this type can be created in such objects.
This object adds variables into the calculation of the application size, which influences the basic runtime licence type/size (see: Price list of the PROMOTIC system ).
This object adopts properties and methods of the PmaObject object.

Root Returns reference to the root application object PmaRoot
:
onEndOfTransfer Is triggered after ending the data transfer
:
onStart Is triggered for each object in the runtime only once at the beginning
onStop Is triggered for each Pma object in the runtime mode only once at the stop of the application

History:
Pm9.00.00: Object name changed: PmDataTable -> PmaDataTable
Pm8.03.15: The first column can now be defined as Identifier type. This row identifier can be used for example in the Item property for addressing the table cell.
Pm8.03.14: On the "Columns" tab there is a new "Read only" configurator for each new column. The variable in such column can be written only once and these variables are not included into the total variable count of the application. This fact then affects the type of basic runtime licence to be used. See "Read only" columns.
