I have a Swing based application containing a JTable. Now I would like to allow each row to be updated or deleted, using a unique row ID. So I want to add an update and delete button to each row, which have the capability to support an ActionListener. However, I have no idea how to do this using NetBeans.
To display a button in a column you need to create:
a custom renderer to display the JButton
a custom editor to respond to the mouse click
Read the section from the Swing tutorial on How to Use Tables. The section on:
Using Custom Renders will explain the basics of using a renderer
Using Other Editors will explain the basics of using an editor
Working example are provided in the tutorial that you can download.
You can check out Table Button Column for one approach.
The code uses a single class to implement the custom renderer and editor that you will need for the column to display your text as a button.

Java Swing: I recently started learning Swing and I want to add several labels, one button, and three combo box INSIDE A Drop Down Pane! When the user clicks the drop down pane, you can see labels, textfields and comboboxes which will contain the values and when the users clicks drop down pane again, then all the textfields, labels etc are hidden. Is it possible and if yes then could you please help me out (code would be very much appreciated). If you did not understand the design then please visit emirates.com and click on 'Book a Flight'! I'll be trying to implement that type of design
If you want a multi-row data display object, and you want multiple interactable components on the row, don't use the wrong tool, a JComboBox, for this. Use a better tool: a JTable.
Can I show a PDF in a column of a JTable as link to download!? Is that possible
cause I've searched on Google but can't find anything,
Actually I have table in database named projet(id,nomprojet,date,cout,rapportpdf,pdf). Some projet have a rapport some else no, so i have the project ligne in JTable
Can i have column as link to save rapportpdf on Desktop,
Maybe one approach would be to have the column containing the link to be rendered as a button. See Table Button Column. Then when the user clicks on the button you can display the pdf.
If you want the column to look like a regular hyperlink, then you would need to create a custom renderer so it display like a link and a custom editor to invoke the action when you click on it. MadProgrammer has given you the link to the tutorial which explains renderers and editors in more detail.
I'm writing an Eclipse plugin for a screen definition editor. The preview page will have multiple tables of different rows/columns definitions, the contents of each cell is effectively a control definition (i.e. Label, TextBox, etc). Some basic requirements of the preview are:
User selection on any cell publishes the control properties to another view.
The cell styling is applied depending upon the control type.
Currently using JFace TableViewers but have the following issues:
1. Only one TableViewer can be registered as a selection provider via the getSite().setSelectionProvider(). How to listen for selection changes on all my tables?
2. TableViewer does not appear to allow for cell styling.
3. Cell selection programatically handling with a TableCursor, but the cell in a previous table is still highlighted when I select another cell in another table.
Are there more suitable layouts to use than TableViewer for my purposes?
Regarding point #2, cell styling, TableViewers do allow for customization of the display of cell data. Take a look here for some ideas on how to get started with that.
You can use this approach for supporting selection in multiple tables with some modification (add listener to each of your table viewers so if one of them is selected it automatically becomes the delegate).
I've got a CellTable wich work with SingleSelectionModel to make single selection and show some information into details panel. Also I've got CheckBoxCell column into this CellTable which work with another MultipleSelectionModel to make mass delete operation.
When I try to click on check box in CheckBoxCell column GWT selects row and after second click on checkbox it change checkbox state. So we should make two clicks, but I need to do it (change checkbox state) by one click.
I tried different ways to fix it:
Change dependsOnSelection and handlesSelection parameters into CheckboxCell
Change SelectionEventManager in CellTable (DefaultSelectionEventManager.createCheckboxManager(), DefaultSelectionEventManager.createCustomManager)
But it doesn't work.
I found similar problems into Internet but all of them work with one MultipleSelectionModel. It's not the same what I want, because there's details panel (So I could make only single selection).
Can anyone help me to figure out how to resolve it?
UPD:
I've just removed SingleSelectionModel and redesigned UI to working with MultipleSelectionModel. It's GWT-hell..
Try to switch your selection models: use the MultiSelectionModel as the CellTable's selection model, so that the checkboxes work as expected (with both dependsOnSelection and handlesSelection set to true), and for the master-detail feature, use a CellPreviewEvent.Handler (or DefaultSelectionEventManager#createCustomManager), and RowStyles and getRowElement+addStyleName/removeStyleName for rendering (RowStyles when the CellTable renders the rows, then getRowElement to dynamically update styling).
I want to render a text field and a button within a cell of a table. It's too easy in Swing but i am not able to find any example for SWT.
I'd very appreciate an example using WindowBuilder.
