User-Defined Function Editor

The User-Defined Function Editor dialog helps you to write a user-defined function which can be called in dynamic formulas or other user-defined functions. This dialog appears when you expand the Dynamic Resources > User-Defined Functions node in a resource list, then select <Add Function…>, or right-click a user-defined function and select Edit from the shortcut menu in the Resources panel of Web Report Studio.

Function Name

Specifies the name of the function.

Fields box

Displays a list of fields that are available to functions. The fields include the group, detail and aggregation objects in the current business view, and the dynamic formulas and aggregations that have been created in the report. You can select one field and double-click it to insert the field into the editing box at the insertion point.

Functions box

Displays a list of the Logi JReport built-in functions and user-defined functions that are available to functions. When you select one function and double-click it, Logi JReport will insert the selected function into the editing box at the insertion point completely with its required syntax items (parentheses, commas, and so on).

Operators box

Displays a list of operators that are available to functions. Select one operator and double-click it to insert the selected operator into the editing box at the insertion point.

Editing box

In this box, you can build and edit your function. There are several ways to work with functions:

• Select function components from the Fields, Functions and Operators boxes, and then double-click the components, Logi JReport will then insert them in the function;
• Type your function in the editing box directly;
• Use the above two methods together;
• Paste function text from the text document of other programs.

Tests the syntax of your function. If the syntax is incorrect, Logi JReport provides an opportunity to correct the errors.

Selects a general operator to be used in the editing box.

A color palette is provided for you to insert the HEX code of a color simply by selecting the corresponding color in the color palette instead of inputting the HEX code manually.

OK

Creates or edits the function and closes the dialog.

Cancel

Cancels the creating or editing of the function and closes the dialog.
