If the product code use ControlDecoration to show the hover text besides a
text control, does SWTBot support testing it? If support, which API should
I use? Thanks in advance!

P.S. Here is a sketch of a class that encapsulates this (assumes the control
has its decoration in getData("CONTROL_DECORATION") and uses reflection for
checking if the decoration is visible):
public class SWTBotControlDecoration {
private final AbstractSWTBot<? extends Control> mControl;
private final Field mVisibleField;
public SWTBotControlDecoration(AbstractSWTBot<? extends Control>
control) throws Exception {
mControl = control;
mVisibleField =
ControlDecoration.class.getDeclaredField("visible");
mVisibleField.setAccessible(true);
}
public Image getImage() {
return UIThreadRunnable.syncExec(mControl.display, new
Result<Image>() {
@Override
public Image run() {
return getDecoration().getImage();
}
});
}
public boolean isVisible() throws Throwable {
return UIThreadRunnable.syncExec(mControl.display, new
Result<Boolean>() {
@Override
public Boolean run() {
try {
return mVisibleField.getBoolean(getDecoration());
} catch (Exception e) {
throw new RuntimeException(e);
}
}
});
}
private ControlDecoration getDecoration() {
return (ControlDecoration)
mControl.widget.getData("CONTROL_DECORATION");
}
}
