NatTable is a SWT widget. So of course you can check the focus state as with any other SWT widget. For the selection state you need access to the SelectionLayer.
If you want to change the styling when the focus on the NatTable changes, simply implement and register a FocusListener that dynamically changes the styling directly in the ConfigRegistry:
natTable.addFocusListener(new FocusListener() {
@Override
public void focusLost(FocusEvent e) {
Style style = new Style();
style.setAttributeValue(
CellStyleAttributes.BACKGROUND_COLOR,
GUIHelper.COLOR_GRAY);
natTable.getConfigRegistry().registerConfigAttribute(
CellConfigAttributes.CELL_STYLE,
style,
DisplayMode.SELECT);
}
@Override
public void focusGained(FocusEvent e) {
Style style = new Style();
style.setAttributeValue(
CellStyleAttributes.BACKGROUND_COLOR,
GUIHelper.COLOR_BLUE);
natTable.getConfigRegistry().registerConfigAttribute(
CellConfigAttributes.CELL_STYLE,
style,
DisplayMode.SELECT);
}
});
Have in mind that the selection anchor is styled differently.
