Hi,
I tried search any snippets or articles related to this topic, but I have
not found.
Currently, I do an iteration to initialize the check state for each item
after setInput();
public void reloadDataIntoView(){
theTableViewer.setInput(getModel());
for (TableItem item: theTableViewer.getTable().getItems()) {
ModelType data = (ModelType)item.getData();
item.setChecked(data.isChecked());
}
}
But I think, perhaps somebody could tell me there is other better methods to
achieve this purpose.
Thanks!
Best regards,
Yau. K.J.

Hi,
There's not API for this though it might make sense. Could you file a
bug against Platform/UI and cc me on the bug.
In the meanwhile you could subclass CheckedTableViewer and overload
protected ViewerRow internalCreateNewRowPart(int style, int rowIndex) {
super.internalCreateNewRowPart(style|SWT.CHECK, rowIndex)
}
This internal API and CheckedTableViewer says you should not subclass
but its the only possibility I currently see without revisiting the
whole table items. Please not that this method is called whenever a new
item is created.
