Tabs Won't Work In Right Aligned JPanel
Hello
I had also had this posted at another form but haven't been getting too much of a reply base...
forums.sun.com MessageID 10375594
I'm tring to setup a JPanel using a style object for formating, JPanel.setLogicalStyle(styleimade);, and I have everything working beautifuly for a left alligned panel, but when I attempt to work with tabs on a panel that is right aligned, StyleConstants.setAlignment(styleimade, ALIGN_RIGHT), I can't seem to get tabs to work at all. Using StyleConstants.setTabSet(styleimade, atabsetimade) to set the tabs. When I make my tabset it doesn't matter what I have my tabstops set to the indention doesn't change. When I set the alignment back to left, the tabs start to work.
When I try to do a search on documentation I naturally get a huge list of tabpanels, and can't seeem to find anything on this particular subject.
Any suggestions or links to other forums would be a huge help.
Thank you in advance!
Here's the compileable code to what I am tring to do.
