I am trying to make a combobox in table viewer in Eclipse SWT.pointing me in the right direction.I think I've done everything ok until now, problem is the combo box not display in the table,I got error this:
Error:
Block of Code is:
public void createPartControl(Composite parent) {
System.out.println("createPartControl call");
// For Testing
Composite tableComposite = new Composite(parent, SWT.NONE);
tableColumnLayout = new TableColumnLayout();
tableComposite.setLayout(tableColumnLayout);
tableComposite.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true,
true));
tableViewer = new TableViewer(tableComposite, SWT.MULTI | SWT.H_SCROLL
| SWT.V_SCROLL);
tableViewer.setContentProvider(ArrayContentProvider.getInstance());
// TODO viewer.setLabelProvider(new ViewLabelProvider());
table = tableViewer.getTable();
// Table table = tableViewer.getTable();
table.setHeaderVisible(true);
table.setLinesVisible(true);
String[] titles = { "Threat Name", "Category Name", "Status",
"Priority", "Description", "Justification" };
for (int loopIndex = 0; loopIndex < titles.length; loopIndex++) {
tableViewerColumn = new TableViewerColumn(tableViewer, SWT.NONE);
TableColumn tblclmn = tableViewerColumn.getColumn();
tableColumnLayout.setColumnData(tblclmn, new ColumnPixelData(200,
true, true));
tblclmn.setText(titles[loopIndex]);
}
}
private void fillRows(String shortdesc, String categ, String descp) {
System.out.println("fillRows call from above method.");
TableColumn status_Name_Col = tableViewer.getTable().getColumn(2);
System.out.println("**************** status_Name_Col ************ "+ status_Name_Col);
tableViewerColumn.setLabelProvider(new ColumnLabelProvider()
{
#Override
public String getText(Object element)
{
Dummy p = (Dummy) element;
return p.getValue();
}
});
tableViewer.addSelectionChangedListener(new ISelectionChangedListener()
{
#Override
public void selectionChanged(SelectionChangedEvent selectionChangedEvent)
{
StructuredSelection selection = (StructuredSelection) selectionChangedEvent.getSelection();
System.out.println(((Dummy) selection.getFirstElement()).getValue());
}
});
List<Dummy> elements = new ArrayList<>();
for (int i = 0; i < Connection.Number_Of_Connection; i++) {
elements.add(new Dummy("First option"));
}
tableViewer.setInput(elements);
tableColumnLayout.setColumnData(status_Name_Col, new ColumnWeightData(1, true));
tableViewerColumn.setEditingSupport(new FirstValueEditingSupport(tableViewer));
}
The assertion message is pretty clear - you must set a label provider for each column in the table.
You don't show us where you are calling fillRows but setting the column label provider in that method looks wrong - set the label providers in your loop creating the columns.
From this code.makery blog, i was able to understand how tableview sorting and filtering works and implement. The problem is the blog showed an example that does not use ListProperty. When i tried to change the code example with ListProperty no sorting and filtering happens.
This is what the blog provided
FilteredList<Person> filteredData = new FilteredList<>(masterData, p -> true);
filterField.textProperty().addListener((observable, oldValue, newValue) -> {
filteredData.setPredicate(person -> {
if (newValue == null || newValue.isEmpty()) {
return true;
}
String lowerCaseFilter = newValue.toLowerCase();
if (person.getFirstName().toLowerCase().contains(lowerCaseFilter)) {
return true;
} else if (person.getLastName().toLowerCase().contains(lowerCaseFilter)) {
return true;
}
return false;
});
});
SortedList<Person> sortedData = new SortedList<>(filteredData);sortedData.comparatorProperty().bind(personTable.comparatorProperty());
personTable.setItems(sortedData);
The following is SSCCE for my implementation with ListProperty

I have a table with quantity and price columns that are editable and not disabled. The table is populated with ObservableList<Collection> . Collection object has a boolean attribute paid. What i am tring to achieve is whenever paid is true, make both price and quantity tablecells disabled and not editable.

The problem with my code is that as i scroll down the table and up again, cells which were previously enabled and editable change to disabled and not editable.
Before scroll After scroll:
The first problem is that you don't reset the state when a cell is reused from one which is paid to one which is not paid. This will happen, among other times, when you scroll. If a cell was previously used in a row that represented a "paid" item (so it is disabled, not editable, and has a red border), and is reused for an "unpaid" item, your updateItem() method will not change the editable or disabled state (or the style). So you should have something like:
if (item != null && item.isPaid()) {
setDisable(true);
setEditable(false);
this.setStyle("-fx-text-fill: grey;-fx-border-color: red");
} else {
setDisable(false);
setEditable(true);
setStyle("");
}
The second problem is that you have no control over the order in which the cell's state is updated. It seems that sometimes the row property is updated after the updateItem() method is called, so you end up with inconsistent state. You can safely use the cell's index to get the correct item from the table's data.
Also note that since both cell factories are identical, there is no need to replicate the code. This works for me:
#Override
public void start(Stage primaryStage) throws Exception {
TableView<Collection> tv = new TableView();
tv.setEditable(true);
TableColumn<Collection, Number> colQty = createQuantityColumn();
Callback<TableColumn<Collection, Number>, TableCell<Collection, Number>> cellFactory = new Callback<TableColumn<Collection, Number>, TableCell<Collection, Number>>() {
#Override
public TableCell<Collection, Number> call(TableColumn<Collection, Number> paramTableColumn) {
return new TextFieldTableCell<Collection, Number>() {
#Override
public void updateItem(Number s, boolean b) {
super.updateItem(s, b);
if (! isEmpty()) {
Collection item = getTableView().getItems().get(getIndex());
// Test for disable condition
if (item != null && item.isPaid()) {
setDisable(true);
setEditable(false);
this.setStyle("-fx-text-fill: grey;-fx-border-color: red");
} else {
setDisable(false);
setEditable(true);
setStyle("");
}
}
}
};
}
};
colQty.setCellFactory(cellFactory);
TableColumn<Collection, Number> colPrice = createPriceColumn();
colPrice.setCellFactory(cellFactory);
TableColumn<Collection, Number> colAmount = createAmountColumn();
TableColumn<Collection, String> colMno = createMNOColumn();
tv.getColumns().addAll(colMno, colQty, colPrice, colAmount);
tv.getItems().addAll(getCollection());
Scene scene = new Scene(new BorderPane(tv), 600, 400);

I am creating an app using WindowBuilder in eclipse 4.4.2. I've added CTabFolders and corresponding CTabItems. The tabs are displayed properly when Click the preview button(Quickly test/preview the window without compiling or running it) in windowbuilder.
Screen Shot===> http://i.imgur.com/Sx9TQrL.jpg
But the real problem is when I run the app,the tabs are not displayed.

Can anyone suggest a solution. Thanks in advance.
And Finally I've figured the problem in the code. The composite in the base layout was assigned with the StackLayout as follows.
Composite content = new Composite(shell, SWT.BORDER);
content.setLayout(new StackLayout());
content.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
When I changed the StackLayout to GridLayout, I got a working solution.
Composite content = new Composite(shell, SWT.BORDER);
content.setLayout(new GridLayout(1, false));
content.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
The barchart is displayed as small icon on a composite of a view in Eclipse RCP plugin. The chart does not cover the entire composite which should be the actual case. what additional setting needs to be made in code to display the graph on entire composite
Following is the code for displaying the bargraph
final CategoryDataset dataset = createDataset();
final JFreeChart chart = createChart(dataset);
if(flag == false){
frame.dispose();
}
frame = new ChartComposite(barchartComposite,SWT.NONE,chart,true);
frame.setLayoutData(new GridData(GridData.FILL_BOTH));
frame.setChart(chart);
frame.forceRedraw();
frame.pack();
frame.setVisible(true);
flag= false;
The method createDataset() generates the data for the barchart and method createChart(dataset) generates the barchart.

You have to modify the parent composite named barchartComposite.
parent.setLayout(new GridLayout(1, false));
parent.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
final CategoryDataset dataset = createDataset();
final JFreeChart chart = createChart(dataset);
Composite barchartComposite = new Composite(parent, SWT.NONE);
barchartComposite.setLayout(new GridLayout(1, false));
barchartComposite.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true));
ChartComposite frame = new ChartComposite(barchartComposite, SWT.BORDER,chart,true);
frame.setLayoutData(new GridData(GridData.FILL_BOTH));
You have to make sure that barchartcomposite grabs the wohle space of the parent composite. This can be achieved with GridLayout and GridData.
