Why does the Print method of a JdbTable only print out a partial set of data from the dataset?

投稿者:: Christopher Moeller

概要: JdbTable is a container that displays a portion of data from the dataset, but is not the dataset itself.

Question:

In JBuilder 5 I have an application which uses a JdbTable to display data from my dataset, but when I call the Print method (implemented in java.awt.Container), only the first page of my dataset is printed to my Printer. Why does it not print out the entire table?

Answer:

The JdbTable is a data-aware component that is used to display data from a datasource (e.g. query). The JdbTable is not the datasource (which contains all of your data), the JdbTable displays only a subset of data from the dataset, depending on the specific display properties set within the component. In otherwords, the reason that you are only able to print out a single page is because only a single page of information is viewable (from the JdbTable) To see this behavior, you can modify the rowHeight property to a smaller amount to display more rows from the dataset, and then reprint it. You will see that more rows are printed now that more rows are viewable in the JdbTable.
