Scrollable JFrame as a ToolTip
Hi,
I have a lot of information in HTML format that I display as a tooltip for my swing app.
Since this is a lot of information, not everything is being visible once the tooltip appears.
I was wondering if there is a way to override the tooltip component so that I can display a JFrame with possibly a JScrollPane with a JTextArea in it. I got this idea from Eclipse IDE where we get tool tip like information as java documentation for any particular component in the code when we do a moseover it. I really like the idea of it being focussable upon pressing F2 and then we get a immovable tooltip which looks like a Scrollable text area which doesnt disappear upon clicking. Also it allows text highlighting and copying from it. I am trying to create something on Eclipse's tooltip lines for my application. Any leads would be helpful.
Thanks.
It is possible to override the tooltip to display another component. Just search this forum, you are sure to find something.
You could also implement your own JWIndow component and place in it anything you want and just show this on your components when the mouse hovers over it for a few seconds. It is should probably be simpler to achieve than trying to re-write the tooltip component, IMHO

JScrollableToolTip
The code of this scrollable tooltip contains a "main"-method for testing and for showing how to use "JScrollableToolTip".
NOTE for tooltip in a JTable:
When we want to use "JScrollableToolTip" for the cells of a JTable,
we must know, that the cell renderer is only indirectly concerned.
Primarily it's the JTable which is responsile for the tooltip. JTable uses only the tooltip text of the renderer.
Thus we must override JTable #createTooltip() to return an instance of "JScrollableToolTip"
and not the createTooltip-method of the renderer component (it is nether called).
We may also need to override getToolTipLocation if the tooltip is outside the row height.

tipArea.setLineWrap(true);

How to make JFrame scrollable?
How can I make a JFrame scrollable? So that when I resize the JFrame to a smaller size the contents remain accessible? The way it is now is that when I resize a JFrame I can't access the components that fall out of the window (I'm using absolute component positioning within the JFrame). I thought adding two scrollbars to take care of this would be easy, but so far I haven't been able to get it right. Any suggestions would be appreciated.
Why dont you put all your components in a JPanel, add a scrollpane to it and then add that JPanel to
ur JFrame.

Hi!
I want to make a JFrame Scrollable.
How can I do it?
I am posting my code below.
JFrame frame = new JFrame("Title");
JFrame.setDefaultLookAndFeelDecorated(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setResizable(true);
frame.setSize(500,500);
//adding the panles to the contentpane
Container contentPane = frame.getContentPane();
//contentPane.setLayout(new GridLayout(9,1));
contentPane.setLayout(new BoxLayout(contentPane,BoxLayout.Y_AXIS));
Thanksadd a JScrollPane to the contentPane, add a JPanel to the JScrollPane, set the layout on that JPanel and use that JPanel to add other components.

Hi,
I have this GUI application (written in swing), and some times I need to change title of my main frame (JFrame). I do it simple with setTitle() method.
The problem is that this title is also a tooltip in taskbar. So I need to have JFrame title different from tooltip text in taskbar (when you position mouse pointer on the taskbar).
Is this possible?
Any idea?
Thanx in advance!Swing questions should be asked in the swing forum.
My guess would be that you lose. The tooltip on the taskbar comes from the OS, not java. I'd imagine that the OS just pulls the title from the window and displays that.
I guess if you really need a hack, you can try making the root frame of your application always hidden, and have the display be a child Dialog of the root frame. That might work, but I haven't tested it and I'm pretty convinced the sheer ick factor outweights most potential benefits. -

How can I display the tooltip in a tree node?
I implement a TreeCellRenderer and has already set the tooltiptext through the following code:
public Component getTreeCellRendererComponent(JTree tree, Object value,
boolean selected, boolean expanded,
boolean leaf, int row,
boolean hasFocus) {
Object userObject = ((DefaultMutableTreeNode)value).getUserObject();
if(Leaf.class.isInstance(userObject)) {
Leaf leaf = (Leaf)userObject;
setToolTipText(leaf.getString());
}Why can't the tree display the tooltip when a move the mouse on the leaf of the tree?
Thank you!import java.awt.*;

public class Test3 extends JFrame {
public Test3() {
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Container content = getContentPane();
JTree jt = new JTree() {
public String getToolTipText(MouseEvent evt) {
if (getRowForLocation(evt.getX(), evt.getY()) == -1)
return null;
TreePath curPath = getPathForLocation(evt.getX(),
evt.getY());
return curPath.getLastPathComponent().toString();
content.add(new JScrollPane(jt), BorderLayout.CENTER);
jt.setToolTipText("");
setSize(400, 400);
setVisible(true);
public static void main(String[] args) { new Test3();
}It sounds a solution. I use the following code and also can display the tooltip,but there's also a problem:
mytree.setCellRenderer(new MyTreeCellRenderer());
ToolTipManager.sharedInstance().registerComponent(mytree);the above code only effective when the function getTreeCellRendererComponent in MyTreeCellRenderer like the following:
public Component getTreeCellRendererComponent(JTree tree, Object value,
boolean selected, boolean expanded,
boolean leaf, int row,
boolean hasFocus) {
String stringValue = tree.convertValueToText(value, selected,
expanded, leaf, row, hasFocus);
setText(stringValue);
setToolTipText(stringValue); //Tooltips used by the tree
/* Set the icon of the node */
Object userObject = ((DefaultMutableTreeNode)value).getUserObject();
if(Device.class.isInstance(userObject)) {
setIcon(deviceIcon);
} else {
setIcon(nullIcon);
Business b = (Business)userObject;
setFont(defaultFont);
/* Update the selected flag for the next paint. */
this.selected = selected;
this.hasFocus = hasFocus;
if(selected) // && hasFocus)
setForeground(Color.white);
else
setForeground(Color.black);
return this;
}but when the code is bellow,it displays nothing(Only the leaf node need tooltip):
public Component getTreeCellRendererComponent(JTree tree, Object value,
boolean selected, boolean expanded,
boolean leaf, int row,
boolean hasFocus) {
String stringValue = tree.convertValueToText(value, selected,
expanded, leaf, row, hasFocus);
setText(stringValue);
//setToolTipText(stringValue); //Tooltips used by the tree
/* Set the icon of the node */
Object userObject = ((DefaultMutableTreeNode)value).getUserObject();
if(Device.class.isInstance(userObject)) {
setIcon(deviceIcon);
} else {
setIcon(nullIcon);
Business b = (Business)userObject;
if(b.isShowOrder())
setToolTipText(b.getContaId()); // only some node need tooltip, not all node
setFont(defaultFont);
/* Update the selected flag for the next paint. */
this.selected = selected;
this.hasFocus = hasFocus;
if(selected) // && hasFocus)
setForeground(Color.white);
else
setForeground(Color.black);
return this;

Is there any way to solve this tooltip issue besides addFocusListener?
Following up with my last posted thread that now has the record of 23 responds and none relevant to my question, I'm posting another one right now.
I've managed to reproduce the issue I was talking about and have the code. Basically, my problem was that tooltip was causing popups to go behind the main frame. You can reproduce this by moving your mouse on the table and generate tooltips, after you comment out the focus listener, which is the solution. If table is in focus, tooltips are generated, otherwise, no tooltips.
What I'm wondering about if anyone knows any other way besides the focus listener to implement this fix and check to see if the table has focus? The reason I'm asking this, although it seems to work fine on this code, is because in my application at work, which has more than 10 panels in it, this table's tooltip problem affects all those other panels as well, not just this story popup on the table. When I open any of the other panels, the table doesn't necessarily lose focus, and when I close them, the table won't necessarily gain back focus, which is what I want to see happen.
I'd appreciate your relevant suggestions and ideas to my problem. Thanks!

I've managed to reproduce the issueSee what happens when you put your mind to creating a SSCCE, instead of wasting time with unnecessary comments complaining about the lack of help?
Basically, my problem was that tooltip was causing popups to go behind the main frameSorry I still don't see a problem or understand your problem. I've tried the code with and without the FocusListener. In both cases the "popup frame" is always displayed on top of the main frame. This is what I did:
a) place mouse on the table
b) wait for popup to display
c) click on table to show popup
In both cases the popup was displayed on top of the main frame.
When the FocusListener code was commented out, I could still get the tooltip. However, when the FocusListener was active, I could not get the tootip to redisplay after the popup was made the active window.
I'm using JDK6 on XP.
By the way, normally applications are written with a single JFrame. Additional "popups" would be created by using a JDialog and you would specify the frame as the owner of the dialog. Note this should prevent the dialog from displaying behind the frame. -
Applet, JFrame: Display icons in toolbar
Hello,
I've a class called Designer which extends Applet. In the init method two JFrames are opened: DesignerFrame and DrawPanel. In the DesignerFrame I have a toolbar with icons. When I run the Applet in Eclipse (on my local computer) he shows the icons. When I put the application on my webserver, and I open it with my browser on my local computer, he doesn't show the icons. The icons are in a folder called pwdImages.
Does anyone know how to solve this problem?
Thanks a lot!!!
Koen.Hello,
Thanks for the answers. Here's some code of the DesignerFrame class:
// Handles color menu items
class ColorAction extends AbstractAction {
public ColorAction(String name, Color color) {
super(name);
this.color = color;
String iconFileName = "pwdImages/" + name + ".gif";
if (new File(iconFileName).exists())
putValue(SMALL_ICON, new ImageIcon(iconFileName));
public ColorAction(String name, Color color, String tooltip) {
this(name, color);
if (tooltip != null) // If there is a tooltip
putValue(SHORT_DESCRIPTION, tooltip); // ...squirrel it away

How to hide tooltips on user action
Generally Tooltips will be displayed for the pre-defined time interval. But is there any way to hide the tooltips when the user performs some action.
Please help me.Hi Thanks for your reply.
But in my case: I have JFrame as main window and JPanel as the workspace. JFrame also had toolbar. User can click a button in the JPanel to replace the existing panel with new panel. The toobar buttons will be changed based on the panel that is currently shown.
Now,
1) Focus the button (using keyboard) on the on the panel.
2) Place the mouse pointer on one of toolbar button to show tooltip.
3) Press the button (use keyboard) on the panel to get the new panel.
Do steps 2) and 3) with very less time gap.
In this case new panel will be displayed with new toolbar icons but the tooltip of previous toolbar button still showing.
I know the problem is that the tooltip show time is more than the time that took for changing the panel.
Is there any other way to fix this, instead of decreasing the tool tip dismissdely time. -
