Examples with ValueControlledDialogPane org.knime.core.node.dialog.ValueControlledDialogPane used on opensource projects

Example 1 with ValueControlledDialogPane

use of org.knime.core.node.dialog.ValueControlledDialogPane in project knime-core by knime.

the class Node method getDialogPaneWithSettings.

/**
 * @param inSpecs The input specs, which will be forwarded to the dialog's
 *        {@link NodeDialogPane#loadSettingsFrom(NodeSettingsRO,
 *        PortObjectSpec[])}.
 * @param settings The current settings of this node. The settings object
 *        will also contain the settings of the outer SNC.
 * @param isWriteProtected Whether write protected, see
 *        {@link org.knime.core.node.workflow.WorkflowManager#isWriteProtected()}.
 * @return The dialog pane which holds all the settings' components. In
 *         addition this method loads the settings from the model into the
 *         dialog pane.
 * @throws NotConfigurableException if the dialog cannot be opened because
 *             of real invalid settings or if any preconditions are not
 *             fulfilled, e.g. no predecessor node, no nominal column in
 *             input table, etc.
 * @throws IllegalStateException If node has no dialog.
 * @see #hasDialog()
 * @since 2.6
