I have created one Class for auto complete text fields.
I want to use that Class and try to include my JTable cell fields, but it won't display.
Please advice
you can to use AutoComplete JComboBox / JTextField
put this JComboBox / JTextField to the JTable as Renderer and Editor
(Assuming I understand the question)
You need to wrap your editor in TableCellEditor. Have a look at Using Other Editors an example.
Once you have it set up, you need to register the editor with the table.
One way is to register the editor with the column in question via the TableColumnModel
table.getColumnModel().getColumn(indexToColumnInQuestion).setCellEditor(tableCellAutoCompleteEditor);

I am trying to recreate this "TreeGridWithCheckBoxFieldsExample" from the natTableExamples, and I wanted the first column editable, not only the Checkbox but also the Text it contains.
But when I register for TextCellEditor I am not able to set the CheckBox value by clicking it, if I click on CheckBox it goes to edit mode for the text beside it because of the MouseEditAction() in the below code.
uiBindingRegistry.registerFirstSingleClickBinding(
new CellPainterMouseEventMatcher(
GridRegion.BODY,
MouseEventMatcher.LEFT_BUTTON,
checkBoxPainter),
new MouseEditAction());
But if I remove it I won't be able to select the CheckBox, and because of DefaultBooleanDisplayConverter in the below code, the text after editing is not getting edited because the dataValue it gets is of boolean type .
configRegistry.registerConfigAttribute(
CellConfigAttributes.DISPLAY_CONVERTER,
new DefaultBooleanDisplayConverter(),
DisplayMode.NORMAL,
TreeLayer.TREE_COLUMN_CELL);
Thanks.
This is afaik not supported out of the box. Converters and editors are registered per column/cell. Mixing two editors and converters in one column/cell for two different properties of one row object is nothing to achieve easily. You will need to implement custom mechanisms to achieve that.
I wanted to know how to add 2 small button into a cell. This is used for 'Quantity' column in my jtable.
I want to do as the image above, user are allowed to edit the number inside or clicking add or minus the number, how do I do it?
The two arrows are part of a component called a Spinner. You can use a JSpinner to create textbox and use the SpinnerNumberModel to allow it to use numerical values:
JSpinner spinner = new JSpinner();
spinner.setModel(new SpinnerNumberModel());
You can read more about spinners in the Java documentation
To add it to a table, you will need a custom class which extends DefaultCellEditor. A few examples can be found here:
Is there a convenient way to use a spinner as an editor in a Swing JTable?
Use JSpinner like JTable cell editor
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.
how to add a jcheckbox when the table model initially is not defined.
I have populated the jtable with data from database, but now I need to add a jcheckbox used for selection of desired record.
I can add jcheckbox to jtable if the datatable rows are perdefined with boolean class. But as I am using a database to read from I am bit confused.
any help is welcome.
JTable relies on its TableModel to determine what to display. Although only existing rows can be shown, you can insert an uncommitted row in the model for editing. What and when to commit are entirely up to your application.
As discussed in How to Use Tables: Concepts: Editors and Renderers, the default renderer and editor for a column of type Boolean is a JCheckBox. Here's a simple example that conditions getColumnClass() accordingly. Here's a more complex example that defines a composite type, Value, as well as a custom renderer and editor.
Actually I want to add a JCombobox in a JTable and fire its action within the JTable.
I am using Netbeans, and I need to know where exactly I should put the code.
Thank you for your cooperation and time.
Best regards.
You can simply add a JComboBox to a JTable if you can follow this tutorial which describes how to use a Combo Box as an Editor, another examples about TableCellEditor are here.
