Viewing Report Pages

Browsing the pages

You can use the following methods to browse the report pages:

• The methods getCurrentPageNumber() and getTotalPageNumber() are used to return the current page number and the total number of pages of the current report onto the screen.
• The method int gotoPage(int pageNumber) is used to display the page specified by PageNumber on the screen. If PageNumber is out of the range of the current report, the first page (if the pageNumber is less than 0), or the last page will be shown on screen. The returned value is the current page number.
• The methods firstPage(), prevPage(), nextPage() and lastPage() are used to show the specified page on the screen.

The return value of the above methods is a string, and can be: "OK", "No more page" or other error messages such as "No report load".

Getting the page orientation

To get the orientation of the report pages, use the method getPageOrientation(). You should call this method after calling the runReport method. The return value is an int value, and can be LANDSCAPE or PORTRAIT. If it is -1, it makes no sense, and is incorrect. For example, you may have called it before calling runReport method.

Zooming the pages

If you want to zoom in or out of the report pages, there is a method named zoom(ratio) that will meet this requirement.

Parameter

• ratio - Integer type, representing a percentage value.

For example, if you want to enlarge the report pages by two times the original size, you can use the method in this way: zoom(200)

To reduce the report size by half, use the method in this way: zoom(50)
