I have a custom swing component that is implemented similar to a JTree. It has a ComponentUI that renders an object list using a CellRenderer. The tooltip now correctly shows for each rendered cell, however it doesn't track the mouse as I would like. For instance, if I have boxes layed out like this; [ box A ] [ box B ] [ box C ]...

Is there a way to sort a JTable programmatically? I have my JTable's sort working (with setRowSorter) so that when the user presses any of the columns, the table gets sorted. I know, SWingX JXTable would probably work, but I'd rather not go through the hassle because everything else is pretty much working now and I don't know how wel...
Why does Swing JComponent class implement the interface Serializable? The way I've implemented my views, they are stateless, all the state data is stored in a Presentation Model. So I don't need to serialize my views. I've used a @SuppressWarnings("serial") annotation to remove the warnings. Are there better ways to remove them? ...

Currently the user can select text, right-click it and select bold from a popup menu, which ends up applying the bold style to the selected text like so: this.getStyledDocument().setCharacterAttributes(this.getSelectionStar...
I am a student at ISU. I was working on a homework assignment where I wanted to get text that was selected (highlighted) in a TextArea to appear in a JOptionPane dialog. I tried many of the methods for JOptionPane, but I could not get any of them to place the text the user selected in the input field of the dialog. I guess that I could ...
