  • Logi JReport UDO does not support RTF and PDF format output. That is, when exporting to RTF and PDF, a report with a UDO may not be rendered correctly. However, there is no such problem for HTML and PS.

Properties of the built-in UDOs

Logi JReport provides you with two built-in UDOs: JHyperLink and JRotator, the properties of which are as follows

JHyperLink

It operates in a similar way to the hyperlink in an HTML file (only for Windows NT). Here are its special properties:

Property NameDescription
Others
Auto FitSpecifies whether to adjust the width and height of the object according to the contents.

Data type: Boolean

Display Value Specifies the displayed text of the hyperlink. This property has lower priority than Display Image.

Data type: String

Enable Hyperlink in Excel Specifies whether to enable the link defined on the object when exporting the report to an Excel file.

Data type: Boolean

Enable Hyperlink in HTML Specifies whether to enable the link defined on the object when exporting the report to an HTML file.

Data type: Boolean

Enable Hyperlink in PDF Specifies whether to enable the link defined on the object when exporting the report to a PDF file.

Data type: Boolean

Executer Class NameIf the specified URL is linked to a .rst file - the Logi JReport Result export result file, you should select jet.udos.RPTExecuter. For other links, use jet.udos.IEExecuter.

Data type: String

Horizontal Alignment Specifies the horizontal justification of the content in the JHyperLink container. Choose an option from the drop-down list.

Data type: Enumeration

HTML StyleSpecifies the CSS style of the JHyperLink in HTML result and in Page Report Studio. The value is a String value containing only the body part of a CSS style definition. Make sure that you input the right css style string.

For Example, if a full style definition is:

style="text-decoration:underline;color:#ffc800;font:italic small-caps bold 12pt serif;"

you need only input the content in the quotation marks as the HTML Style value:

text-decoration:underline;color:#ffc800;font:italic small-caps bold 12pt serif;

Data type: String

TargetSpecifies the window or frame at which to target contents. Choose an option from the drop-down list.
  • blank - Loads the linked document into a new blank window. This window is not named.
  • self - Loads the linked document into the window in which the link is selected (the active window).
  • parent - Loads the linked document into the immediate parent window of the active window. If there is no parent window, the active window is used.
  • top - Loads the linked document into the topmost window.

Data type: Enumeration

Tooltips TextSpecifies the text that will be shown when you hover the mouse pointer over the JHyperLink in Designer view mode, in HTML result, or in Page Report Studio.

Data type: String

Data type: String

OriginalSpecifies from where the image is fetched when viewing or running the report on Logi JReport Server.

The property has following two options:

  • true - If selected, the image will not be delivered when publishing the report to Logi JReport Server. Logi JReport Server will find the image from the local directory specified by the property Display Image when you view the report.
  • false - If selected, the image will be delivered when publishing the report to Logi JReport Server. Logi JReport Server will obtain the image from the server side when you view or run the report.

Data type: Boolean

Accessibility
External AccessKeyIt is mapped to the HTML attribute accesskey. This attribute specifies an access key to the object.

Data type: String

External CSS Class SelectorSpecifies a class selector to be applied to the object when exported as HTML. Enter a valid class name from the CSS file.

Data type: String

HrefLangIt is mapped to the HTML attribute hreflang. This attribute specifies the base language of the resource designated by a link and may only be used when a link is specified.

Data type: String

Example:

Insert two JHyperLink UDOs, and specify the following:

  • URL: http://www.jinfonet.com
    Display Value: Select here.
  • URL: C:\docword.txt
    Display Value: abc
    Display Image: C:\Logi JReport\Designer\Demo\SampleReports\Coffee.jpg

When you point your mouse at either UDO, a hand will show you that it is a hyperlink. By selecting it, you will be taken to the destination. The application launched to open it (the linked file) is from your Windows NT system. If Display Value and Display Image both have been specified, the image has the higher priority to be displayed.

JRotator

It is a built-in UDO that can be rotated. Text and images can be held in JRotator. Following are its special properties:

Property NameDescription

  • 0 - No rotation.
  • positive value - Rotates the JRotator clockwise.
  • negative value - Rotates the JRotator anticlockwise.
