How can I hide/show TableItem in SWT?

I am trying to allow my user to search through a table of information, dynamically hiding/showing results that contain the search. I have the hiding part down, and it works well, but I'm having trouble, showing the table item again, once the search criteria is changed.

Here is my hide code:

searchField.addModifyListener(new ModifyListener() {
            @Override
            public void modifyText(ModifyEvent arg0) {
                modified = true;
                for (int i = 0; i < table.getItems().length; i++) {
                    if (!(table.getItem(i).getText(2)
                            .contains(searchField.getText()))) {
                        table.getItem(i).dispose();
                    }

                }
                if ("".equals(searchField.getText())) {
                    modified = false;
                                    //where I would want to un-hide items
                }
            }
        });

You have probably to save the data from TableItem into collection before you call dispose. Then when you search again you could check that collection and if matches are found, then insert back into Table by creating new TableItem.

Isn't it better to actually operate with some kind of a table model and JFace bindings, rather, then do it like that? And yes, disposing is not hiding. You should probably remove the item from the table.

Looking at your code, it seems you try to hide the item by calling dispose(). If you dispose a widget, it is gone for good. You cannot get it back.

If you want to unhide it again, will have to create a new item at the position of the previously hidden one with the same content.
