Hi
I am not sure if this problem is due to my beginners level java skills
or if there is another issue.
Either way any help you can give would be much appreciated.
I have a JFrame with a box layout and I want to add JPanels to it.
The problem is that if there is more than one JPanel the last one
covers the first one and sets it to the second position.
This is not the right place for the question.
I did try your project, and here's what happens: the first file is
opened in the lower half of the window. When opening the 2nd file,
seemingly nothing happens. But when resizing the window, one can see it
at the bottom third.
It worked without this trick by adding
this.pack();
at the end of processView.
But I'm not sure if this is the best solution, or if it is what you
wanted. If not, what you should do is to ask help on stackoverflow. But
create a project without pdfbox, as it isn't the cause of the problem.
Instead of the rendered image, create an image from scratch with a
random color. (To "write" into a BufferedImage, use getGraphics). Or
change your project that it reads an image from disk. (ImageIO.read)
Asking a good question is a skill. Make a decent title that contains the
words "box layout" (maybe search stackoverflow for this to see whether
it has already been answered). Put "awt" and "swing" as labels of your
question. After asking the question, look at the website from time to
time to respond to comments, i.e. don't wait 24 hours. Newbie questions
receive special screening, so it's likely that you'll get fast feedback.
Re pdfbox, change this line
PDDocument pddocument = new PDDocument();
pddocument = pddocument.load(target);
to
PDDocument pddocument = PDDocument.load(target);
Good luck!
