Constructors Summary
public JToolTip() Creates a tool tip. setOpaque(true); updateUI();

Methods Summary
boolean	alwaysOnTop() Always returns true since tooltips, by definition, should always be on top of all other windows. return true;
public javax.accessibility.AccessibleContext	getAccessibleContext() Gets the AccessibleContext associated with this JToolTip. For tool tips, the AccessibleContext takes the form of an AccessibleJToolTip. A new AccessibleJToolTip instance is created if necessary. return an AccessibleJToolTip that serves as the AccessibleContext of this JToolTip if (accessibleContext == null) { accessibleContext = new AccessibleJToolTip(); } return accessibleContext;
public javax.swing.JComponent	getComponent() Returns the component the tooltip applies to. The returned value may be null. return the component that the tooltip describes see JComponent#createToolTip return component;
public java.lang.String	getTipText() Returns the text that is shown when the tool tip is displayed. The returned value may be null. return the String that is displayed return tipText;
public javax.swing.plaf.ToolTipUI	getUI() Returns the L&F object that renders this component. return the ToolTipUI object that renders this component return (ToolTipUI)ui;
public java.lang.String	getUIClassID() Returns the name of the L&F class that renders this component. return the string "ToolTipUI" see JComponent#getUIClassID see UIDefaults#getUI return uiClassID;
protected java.lang.String	paramString() Returns a string representation of this JToolTip. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be null. return a string representation of this JToolTip String tipTextString = (tipText != null ? tipText : ""); return super.paramString() + ",tipText=" + tipTextString;
public void	setComponent(javax.swing.JComponent c) Specifies the component that the tooltip describes. The component c may be null and will have no effect. This is a bound property. param c the JComponent being described see JComponent#createToolTip beaninfo bound: true description: Sets the component that the tooltip describes. JComponent oldValue = this.component; component = c; firePropertyChange("component", oldValue, c);
public void	setTipText(java.lang.String tipText) Sets the text to show when the tool tip is displayed.

public void	updateUI() Resets the UI property to a value from the current look and feel. see JComponent#updateUI setUI((ToolTipUI)UIManager.getUI(this));
private void	writeObject(java.io.ObjectOutputStream s) See readObject and writeObject in JComponent for more information about serialization in Swing. s.defaultWriteObject(); if (getUIClassID().equals(uiClassID)) { byte count = JComponent.getWriteObjCounter(this); JComponent.setWriteObjCounter(this, --count); if (count == 0 && ui != null) { ui.installUI(this); } }
