Hi,
I use the below and it works like a charm...
int style = SWT.MULTI | SWT.BORDER | SWT.H_SCROLL | SWT.V_SCROLL |
SWT.FULL_SELECTION | SWT.HIDE_SELECTION | SWT.CHECK;
checkTableViewer = CheckboxTableViewer.newCheckList(parentComposite, style);
The above gives me a check table viewer.
Now install check event on the table viewer
checkTableViewer.addCheckStateListener(new ICheckStateListener()
{
public void checkStateChanged(CheckStateChangedEvent e)
{
onCheckStateChanged(e);
}
});
Here is how to implement on onCheckStateChanged(...)
public void onCheckStateChanged(CheckStateChangedEvent e)
{
// The source is simply our checkbox table viewer
CheckboxTableViewer source =
(CheckboxTableViewer)e.getSource();
// Get the element that just got checked/unchecked
MyElementData data = (MyElementData)e.getElement();
// Your 'MyElementData' class should have a flag as a data
// member that toggles its state whether being turned on/off.
// Assuming you have the methods 'MyElementData.setFlag()' and
// 'MyElementData.getFlag()', which returns a boolean.
// Here is how to make sure it's checked for viewer!
if (MyElementData.getFlag() == false)
MyElementData.setFlag(true);
else MyElementData.setFlag(false);
// The above if...else is the same as this--a toggle:
// MyElementData.setFlag(!MyElementData.getFlag());
// Tell the viewer to check it!
source.setChecked(data, MyElementData.getFlag());
// Also, you can get all the checked elements by doing this:
// Object[] checkedItems = source.getCheckedElements().
// The elements are your model data, i.e., MyElementData.
// Eclipse lets you use set the check state via your model
// data! That's cool, because you won't have to worry about
// what the index into rows, etc! This is true OO programming!
}

Thanks. I definetly missed the CheckboxTableViewer class. I've been
experimenting with it and for some reason when i set the grayed state to
true on a node only the check in the checkbox is grayed. The checkbox itself
does not apear 'grayed out'. Does anyone know if this is intentional or a
bug? In either case does anyone know how make that checkbox apear disabled?

I believe you can use your own image for the checkbox. So, based on
your graying out it, you can set the image to the grayed out checkbox.
One example of using one's own images for the checkbox is the JDT's
string externalizer. Open a Java file in the JDT with some hardcoded
strings. Then right-click on the file and choose "Source->Externalize
String".
Hope this helps.

Thanks that does help. Do you know where the source for the JDT externalize
string wizard is?

It's in
<eclipse_root_install_dir> \plugins\org.eclipse.jdt.source_3.0.0\src\org.eclipse.jdt.ui _3.0.0\org\eclipse\jdt\internal\ui\refactoring\nls
The file is ExternalizeWizardPage.java...I am not sure if you are doing
pure SWT or JFace. The above stuff is pretty much JFace.
Hope that helps.
