Examples with JComponent javax.swing.JComponent used on opensource projects

Example 1 with JComponent

use of javax.swing.JComponent in project zookeeper by apache.

the class ZooInspectorConnectionPropertiesDialog method getConnectionProps.

private Properties getConnectionProps() {
    Properties connectionProps = new Properties();
    for (Entry<String, JComponent> entry : components.entrySet()) {
        String value = null;
        JComponent component = entry.getValue();

        }
        connectionProps.put(entry.getKey(), value);

    return connectionProps;
}

Example 2 with JComponent

use of javax.swing.JComponent in project buck by facebook.

the class BuckBuildManager method showNoTargetMessage.
