Question

i try to use an org.eclipse.jface.viewers.CheckboxTableViewer, as a component of a org.eclipse.jface.wizard.WizardPage. I created it this way:

public void createControl(Composite parent) {
    composite = new Composite(parent, SWT.NULL);
    final GridLayout gridLayout = new GridLayout();
    gridLayout.numColumns = 2;
    composite.setLayout(gridLayout);
    setControl(composite);

    /* CheckboxTableViewer */
    viewer = CheckboxTableViewer.newCheckList(composite, SWT.BORDER);
    final Table table = viewer.getTable();
    GridData data1 = new GridData();
    data1.grabExcessHorizontalSpace = true;
    data1.grabExcessVerticalSpace = true;
    data1.horizontalSpan = 2;
    data1.horizontalAlignment = SWT.FILL;
    data1.verticalAlignment = SWT.FILL;
    table.setLayoutData(data1);
    table.setHeaderVisible(true);
    table.setLinesVisible(true);

    checkboxColumn = new TableColumn(table, SWT.LEFT);
    ...

the content of the viewer is inserted dynamically by a contentprovider. Everything works fine on gnome. While testing this on windows 7 (64 and 32 bit also), i am not able to select any entries of that view. Mouseclicks just seems to have no impact on the view.
I added a mouselistener to the table, and the mouseUp-/Down event is fired, selectionChanged and doubleClick on the viewer is not fired. Anyone who can explain this behaviour to me?

thx in advance,

hage

Answer 1

You have to add another style flag while creating the CheckboxTableViewer: SWT.FULL_SELECTION

viewer = CheckboxTableViewer.newCheckList(composite, SWT.BORDER | SWT.FULL_SELECTION);

You can now select rows in the table by a single clicking.
