Print, PDF, Preview JTreeTable - The Demo
This demo sample shows how to Print, PDF or simply preview an existing JTreeTable. You can
"silent print your JTreeTable" using the
JavaTablePrinter methods which
you can learn looking the at the
In the downloaded archive you will see some sample batch programs
For each batch file there is a corresponding JAVA sample program made available
as part of the downloaded archive. Run the
(Unix/Linux) for example to see
the following window with a JTreeTable and few buttons to "Print", "PDF" and
"Preview" the JTreeTable.
The Demo JTreeTable
You can either "Silent print your JTreeTable" or provide UI controls such as menus
and buttons as demonstrated in this sample program and print, PDF, preview and
more. When printing or previewing optionally you can choose to show a print
dialog or a page dialog depending on the parameters values in the
JavaTablePrinter.print() method. In this sample we show a
"print dialog" to let user select a printer, paper, orientation, copies,
fit to printable area and others as seen in the print dialog next.
This is how typical print dialog look like with various printing parameters.
There is the "Fit to Printable Area" option used to fit output within the
Here is how the print preview window looks like when previewed instead of
printing it to a printer directly.
Print JTreeTable with Fit to Page Width
JavaTablePrinter class responsible for generating a report from
JTreeTable lets you set a FIT flag so the output may be fit to the page width.
It is better to always set the flag so it can fit to page width applying
compression if necessary. Available fit options are
AbstractPrinter.PAGE_SCALING_NONE (no fit)
(fit to page width) applied using
In the print dialog there is a check box "Fit to Printable Area" is equivalent
to the above. Here is how the preview page looks like when you apply "Fit"
to page width.
The report engine can let you convert the JTreeTable report pages to a
PDF document. You can convert JTreeTable to PDF completely silently by
JTreeTable to PDF (No Fit)
JTreeTable to PDF (Fit to Page Width)
Pageable from calling
and then passing the
Pageable to the
method. Following are some PDFs created out of sample Swing JTreeTable component.
Report lets you preview JTreeTable report pages in a preview window before printing
or conversion to other data formats.
JavaTablePrinter class has
preview() methods to call for showing the preview window. This
demo chooses to show a paper selection dialog before showing the preview window.
It is also important to remember that the preview window has options for the end
user to Print, PDF and conversion to images. Preview window also lets you zoom in
and out in order to control number of pages to output.
Select paper size and orientation from this "Paper Selection" window.
JTreeTable to PNG, BMP, GIF and JPEG/JPG
Look at the resized image creation samples such as
and other conversion samples in the
There are ways to convert JTreeTable report pages to many different image formats
such as PNG, BMP, GIF and JPEG/JPG. If you want to convert JTreeTable to
images silently we suggest you to get a
(each page of which is an
JavaTablePrinter class and then pass the
Pageable to the
ConversionFactory.saveAsJPG(AbstractPage) (JPG) to convert to
images. Conversion APIs provide the option to pass a resize factor so the
output images size can be enlarged or shrinked.
This demo sample lets you preview the JTreeTable report pages. From the preview
window you can convert one or more of the JTreeTable report pages to images.
JTreeTable to TIFF
This is similar to the above. Get the
Pageable (convert to AbstractPage
array) and call
ConversionFactory.saveAsTIFF(AbstractPage) to produce
the TIFF report.

Report2ResizedTiffDemo.java demo sample in the downloaded archive.
JTreeTable to Post Script
Pageable and create an array of
ConversionFactory.saveAsPostScript(AbstractPage) to produce the
Post Script output of your JTreeTable report.

Report2PostScriptDemo.java demo sample in the downloaded archive.
