Permits component validation and property changes of the value container triggered by the given component.

Parameters:

Ceres 0.10

See Also:

preventPropertyChanges(javax.swing.JComponent), getPropertySet()

preventPropertyChanges

public void preventPropertyChanges(JComponent component)

Prevents component validation and property changes of the value container triggered by the given component.

For example, if a text component loses keyboard focus because another component requests it, its text value will be converted, validated and the value container's property will be changed. For some focus targets, like a dialog's "Cancel" button, this is not desired.

By default, component validation and property changes are permitted for most Swing components.

Parameters:

component - The component.

Ceres 0.10

permitPropertyChanges(javax.swing.JComponent), getPropertySet()

bindEnabledState

public Enablement bindEnabledState(String targetPropertyName,

                                   Object sourcePropertyValue)

Sets the enabled state of the components associated with targetProperty. If the current value of sourceProperty equals sourcePropertyValue then the enabled state will be set to the value of enabled, otherwise it is the negated value of enabled.
