how to set the mandatory property dynamically?

Question

I need to set the mandatory property of some widgets at the run-time depending on some run time criteria and without having a typed reference to the widget. How can I do this?

I can do this for example for the visible property. I can loop through all components of a display or other panel or container by panel.myContainer.getComponents(), select which components I am interested in and then call setVisible(Boolean) on them.

I cannot call setMandatory(Boolean) on this level but I would need to.

Accepted Answer

The problem is that panel.getComponents() returns a list of ULC components. The validation with the mandatory property is an improvement from ivyTeam which is not accessible on ULC level.

The solution would be to cast the ULC component to concrete type of widgets and then call setMandatory(Boolean) on the casted object.

for(Object object : panel.GridBagLayoutPane.getComponents()) 
{
    if(object instanceof RTextField) 
    {
        (object as RTextField).setMandatory(true);
    }
}
