Content pane painting over JPopupMenu
I have a rather complex series of overridden components (JMenuBar, JPanels, JMenus, JFrame, etc.) that I aggregate to form a 'theme frame' --- basically a 'lightweight' L&F decorated frame. The main frame is an UNDECORATED JFrame derivation, in which I basically install a derived JMenuBar class that looks and acts like the top portion of the frame's 'border' (i.e. the title bar), as well as accomodating the menu items for the frame. I then launch several of these frames from the main application, each with its own set of menus (a single top-level JMenu with a few menu items on the popup).
My problem is this... if there are more than 1 of these frames extant after the initial start-up of the application, I can invoke the top-level menu on all of the frames, but only 1 of them actually paints it correctly... the others will show the JPopupMenu, but then the embedded content repaints AFTERWARDS, thus painting over all but the first item on the menu. What's really very bazaar is that it seems to depend totally on location of the frame on the screen (i.e. in relation to the other frames). Initially, only the top-most and/or left-most frame will paint the JPopupMenu correctly, and the rest will exhibit this "show the popup, then paint the content pane over it" behavior.
With the help of print statements, I've been able to determine that the frame which paints the popup correctly DOES NOT get a repaint() notification on it's content-pane, whereas the others do (hence the 'cover-up' behavior of those).
It may be useful to note that the 'content' of these frames are actually applets, which themselves have a complex set of specialized components embedded in them.
None of the menu objects or other components involved are static to the frame class, so nothing's being shared... also, if I move one of the non-functioning windows to a different location on the screen, then the menu works fine... move it back, and the menu gets painted over again.
I'm using JDK 1.4, JBuilder X, all components are Swing.
Any help, please??????

That did the trick! I had a gut feeling it was something simple like that... I still don't fully understand exactly what was going on (why one frame would paint fine, while the others wouldn't), but that's less important than having it work correctly at this point ;-)
Thanks mucho rykk,

TIFF thumbnails do not enlarge in either preview pane or content pane?
I have CS6 Bridge and Photoshop on a new 2014 iMac.
The thumbnail size as viewed on screen is a limited size (around 2cm x 1cm). Enlarging the preview pane just increases the space around the thumbnail rather than the thumbnail increasing to fill the pane. Similarly, in the folder contents panel, if I use the slider bottom right in Bridge this only inreases the size of the space around the thumbnail. It is almost as if I have the max cache set at something really small. But, I don't, it's set at 1000MB.
This phenomenon applies, oddly, only to tiff files. If I use Bridge CS6 to view jpeg or raw files from multiple cameras (.dng,.cr2) it works perfectly. So, only tiffs is the problem.
Any similar problems, resolutions, greatly appreciated. For the moment I have to use Bridge CS4 with PS CS6 as my workround.
Thanks.All of a sudden my Bridge Content panel does not show any info on thumbnail
photos, neither file number nor any metadata preferences. Info is OK in the
Metadata window, but not on Content pane
Also, the file folder thumbnail icons in Content panel now have the file
numbers super-imposed over the file instead of below.
That is caused by accidently hit cmd+T and that command does hide the
thumbnail info and put the name of the folder over the icon.
Hit cmd + T again to solve this or go the menu view and deselect the Show
thumbnail only command
Coincidentally the font size of my Metadata panel suddenly got bigger and
bolder, not the Keyword panel or any other, just Metadata. Doesn't really
bother me, but seems odd these have all just happened
That I have not seen before but might be solved with resetting the prefs as
Tai Lao described in his post. -
hi,
if I have to add three different toolbars in same content pane.
If I add these, each one of them gets overwrite over another. and only last one toolbar gets visible. please help. Also, I need the toolbar to keep top most when i dock them.shamail says - "I guess you didnt read the message carefully"
late4ever says = "u can't add more than 1 toolbar on top"
Did either of you bother to take the time to read the tutorial on "Using Layout Managers". A JToolBar is simply a component. Multiple components can be added to a container. By default the content pane uses a BorderLayout which only accepts 5 components (Center, North, South, East, West) which is why when you keep adding components to the same area you can only see the last one.
When you create a JPanel, by default it uses a FlowLayout. When you add components they get added to the right of the previous component, which was why I gave you the sample code.
I thought my previous answer was straight forward so I only included a piece of code. Here is a complete program you can run:
import javax.swing.*;
public class MultipleToolBars extends JFrame
public MultipleToolBars(String strName)
this.setTitle(strName);
JPanel jp1 = new JPanel();
JToolBar jtb1 = new JToolBar("tool1");
JToolBar jtb2 = new JToolBar("tool2");
JToolBar jtb3 = new JToolBar("tool3");
JButton jb1 = new JButton("JB1");
JButton jb2 = new JButton("JB2");
JButton jb3 = new JButton("JB3");
JButton jb4 = new JButton("TOOL1");
JButton jb5 = new JButton("TOOL2");
JButton jb6 = new JButton("TOOL3");
JButton jb7 = new JButton("BUTTON1");
JButton jb8 = new JButton("BUTTON1");
JButton jb9 = new JButton("BUTTON2");
jtb1.setFloatable(true);
jtb2.setFloatable(true);
jtb3.setFloatable(true);
jtb1.add(jb1);
jtb1.add(jb2);
jtb1.add(jb3);
jtb2.add(jb4);

jtb3.add(jb8);
jtb3.add(jb9);
jp1.add(jtb1);
jp1.add(jtb2);
jp1.add(jtb3);
getContentPane().add(jp1);
public static void main(String[] args)
MultipleToolBars mtb = new MultipleToolBars("test");
mtb.setSize(600, 75);
mtb.setVisible( true ); -
Images disappearing / being painted over
Hi,
Not especially familiar with images and am having issues with images being painted over when ever I move or adjust the size of my GUI. I built a majority of the GUI using the Form Designer included with Netbeans.
Would really appreciate any advice, happy to include more detail if required.
Cheers,
Tim

If you need further help then you need to create a [url http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example Program (SSCCE) that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
Don't forget to use the [url http://forum.java.sun.com/help.jspa?sec=formatting]Code Formatting Tags so the posted code retains its original formatting.
And don't post code generated by NetBeans. It uses the GroupLayout which is not a standard layout manager until JDK6 and a lot of people don't use JDK6 yet so we won't be able to execute you code to see whats happening. -
Greetings!
I'm facing two related problems in developing a Java Applet.
My applet class extends JApplet.
1) The current default layout of the whole window (not individual
components) seems to be a flowLayout. I'd like to set the layout to a
gridBagLayout, however the setLayout command does not seem to be
understood (my compiler is eclipse, JRE 1.5.0 and JDK 5.0), so I
cannot get the following code to work, no specific error msg
generated:
getContentPane.setLayout(new GridBagLayout);
2) similar problem, cannot setBackground or setForeground of the
overall pane.
Please Advise, thanks.

Resetting JApplet Content Pane
I have an applet which needs to wait on another applet in the page being loaded before the GUI components can be rendered on the screen. My plugin appears to load the applets in the order that the HTML tags appear on the page, which is exactly the wrong order. Therefore, I spawned off a task to check for the other applet and load the component when it is present. According to debug output, all goes well. No exceptions are thrown and no debug output indicates any exceptions or error conditions being triggered. Instead, output indicates the GUI getting built and the content pane getting set to the new Container. Unfortunately, this new content pane never displays. Instead, the applet becomes a never-repainted box. What about JApplet and painting am I missing?
You need to do your modifications to Swing components on the AWT thread after the components have be realized, i.e.
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
//// make your changes to Swing components here
}); -
I'm making a JApplet, where I need to draw graphics and set the locations and sizes of some Components. I usually use AWT and just override paint with all of the setSize (...), setLocation (...), and graphics. I tried setting the JApplet's content pane to a JPanel and overriding that JPanel's paint method, but nothing showed up in the JApplet.
So my question is...
How do you draw graphics and set the sizes/locations of components in Swing?
Thanks a lotI tried setting the JApplet's content pane to a JPanel
and overriding that JPanel's paint method, but
nothing showed up in the JApplet.why would you do that? the applet already has a content pane and you need to add your child compenents to that, see documentation:
However using JApplet you need to add the child to the JApplet's contentPane instead:
applet.getContentPane().add(child);
thomas -
I've noticed that there seem to be two common ways in which a Content Pane is defined. I've included examples of each below and am interested in whether there's any reason that either might be preferable to use over the other.
Thanks very much.
EXAMPLE 1 _______________________________
public static void main(String[] args) {
VPA vpa = new VPA();
JFrame frame = new JFrame("VPA");
frame.setContentPane(vpa.contentPanel);
public VPA() {
contentPanel = new JPanel();
EXAMPLE 2 ______________________________________
public static void main(String[] args) {
VPA vpa = new VPA();
public class OtherClass extends JFrame {
public OtherClass() {
Container contentPane = getContentPane();
}I usually create my own content pane then add it to the frame like this:
public class test extends JFrame{
public test{
JPanel contentPane = new JPanel();
//add stuff to contentPane
setContentPane(contentPane);
}When working with frames and swing, JPanel is usually your base content pane. Also, your first code example will not work, don't bother working with it. My example is closest to the second one. -
Differences betw. layered & content panes?
[My apologies if this isn't the correct forum, but I didn't see anything more relevant.]
Aside from the obvious (layering in a LayeredPane), what are the differences between layered and
content panes? Can't a layered pane do everything a (JPanel) content pane can, and more? I've read the
tutorials & the API specs, searched archives and the 'Net until my head spins, but can't get a handle
on this. If I've missed a source, please point me to it.
More specifically, having a vanilla JFrame, would I ever want to use its layered and its content
pane at the same time? If so, what are the relationships between components add()ed
to one wrt those add()ed to the other?
If not (use both simultaneously), why bother having two? Wouldn't it be as effective to ditch the
content pane, and use the layered pane for all operations, just putting everything into the same
layer if you don't need the layering properties?
And while I've got your attention, can I set a LayoutManager on a layered pane and still have its
layering capabilities?
Thanks for your kind attention to this plaint.I can certainly agree with your premises, but I need the
conclusion to be clarified.
LayeredPane is an Object, instantiable, touchable,
manipulable---Check
`content pane' is a concept, a certain location in the
hierarchy of a JFrame (among others)---Check
My head hurts---Check
However, the two both appear as Objects in a JFrame, with
the content pane location occupied by a JPanel (output
heavily trimmed for readability):
BigJFrame[frame0,1153,865,1152x864,rootPane=javax.swing.JRootPane[,0,0,0x0],rootPaneCheckingEnabled=true]
0 JRootPane[,0,0,0x0,layout=JRootPane$RootLayout]
0 JPanel[null.glassPane,0,0,0x0,layout=FlowLayout]
1 JLayeredPane[null.layeredPane,0,0,0x0]
0 JPanel[null.contentPane,0,0,0x0,layout=JRootPane$1]
^^^^^^^^^^^Now obviously I can add Components to the content pane, but
if I assign them layers, will the JLayeredPane be listening
in, and make it so? Will the same happen if I just add them
directly to the JLayeredPane?
I should probably just put a new JLayeredPane in for the
content pane, use it exclusively, and relegate these
questions to a dark corner of my psyche, but that's tough
because I want to know just what's going on so I won't get
hit by some blindside effect later.
<rantlet>
I know Sun says they want to define minimal contracts for
the JFC, so as to avoid painting themselves into a corner,
but after reading the APIs, I was aghast at how much they
left as undefined behavior. I've done more experimenting
with AWT and Swing components than anything else in recent
memory, just to try to avoid the worst of the surprises.
</rantlet>
I also agree that it's time to go home. We should just
sleep on this and see if any revelations appear on the
morrow. -
Here is my problem
I am simply trying to make something paint over an applet. My search brought me to just putting a Canvas over the applet, and then using that to paint, but that didn't work the graphics just return null, and I don't understand why.
I will try to explain this again
I am trying to create a component that will paint over another component, which is a client but that shouldn't matter. And I just can't get anything that to paint over it. I know the canvas is in the right spot, but it just doesn't work (grahpics return null when I do getGraphics() in the canvas). Any ideas?
THANKSAustin187 wrote:
what do I use when I use paint(Graphics g)?Swing is the preferred choice and the Sun tutorials show how to use it (for example in Swing you override "paintComponent" instead of "paint"). Just in case you use AWT, you might want to have a look at this short sample code:
import java.applet.*;

Content Pane: Help getting rid of "Click to activate this control"
I know this came up a long time ago when IE
changed--Flash/swf content needs to be clicked to be activated
first. I thought Robohelp 6 would address it, but not.
The challenge: Cannot use the fixes publised because the html
pages created by Robohelp, like the Content pane, are generated
with Javascript. Ironically posted solutions use Javascript to
change the Embed, object, etc. tags! And I don't know Javascript!
The entire Content pane needs to be clicked first so you can
click an item in the contents. Its html file seems to be
wf_master.htm and when you look at the code, the tags are fed in
like this:
// Build tag to document.write
strObject = "<OBJECT
classid='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000' codebase='
http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0'";
strObject += "WIDTH='100%' HEIGHT='100%' id='masterSWF'
ALIGN='' VIEWASTEXT>";
strObject += "<PARAM NAME='movie'
VALUE='wf_master.swf'>";
strObject += "<PARAM NAME=quality VALUE=high>";
strObject += "<PARAM NAME='menu' value='false'>";
// FlashVars for Object tag:
strObject += "<PARAM NAME=FlashVars VALUE='" +
strFlashVars + "'>";
strObject += "<EMBED src='wf_master.swf' quality=high
WIDTH='100%' menu='false' HEIGHT='100%' NAME='masterSWF'
swliveconnect=true ALIGN='' ";
// FlashVars for Embed tag:
strObject += "FlashVars='" + strFlashVars + "' ";
strObject += "TYPE='application/x-shockwave-flash'
PLUGINSPAGE='
http://www.macromedia.com/go/getflashplayer'>";
strObject += "</EMBED>";
strObject += "</OBJECT>";
Adobe's solutions 1 or 2
http://www.adobe.com/devnet/activecontent/
assume you have regular html files.
*Question/request:
1) Has/can someone come up with a way or code (or function?)
that can be added somewhere centrally (in a key file) so when
robohelp renders the above html tags are replaced therefore
eliminating the need of clicking the swf content to activate it?
I don't know how Robohelp renders to help me find the file
where a change like this can be made.
2) Or can the output Javascript file be modified?
Robohelp seems to ride on Javascript and the 'solutions' are
in Javascript. I can't believe RObohelp developers have not
addressed this with the Robohelp 6.
I upgraded to Robohelp 6, use Robohelp HTML, publish using
FlashHelp, and my users use IE,just search forum - this has been discussed almost everyday
since the issue surfaced a few
weeks/months ago - in fact somebody actually posted a link to
an article explaining it 11 minutes
before you posted your question
Subject: IE Changes Due: What you can Expect.
It's not a flash issue - it is an Eolas/Microsoft issue. Also
google around - tons of articles on
news sites about this and also on adobe and macromedia that
explains it all.

How to add a text area in a Content pane..?
Hi,
I created a content pane with 5 buttons. One of them is a quit button, and I was able to create an "system.exit(0)" event handling for him. My problem is.. I have 4 other buttons, and I want them to show some text when I click them. How do I add a text area bellow my content pane..?
Copy/paste my code to see what im talking about :) :
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class Interface extends JFrame {
public Interface() {
Container contentPane = getContentPane();
contentPane.setLayout(new FlowLayout());
JButton button1 = new JButton("Test1");
JButton button2 = new JButton("Test2");
JButton button3 = new JButton("Test3");
JButton button4 = new JButton("Test4");
JButton button5 = new JButton("Quit");
ButtonHandler handler = new ButtonHandler();
button5.addActionListener( handler );
contentPane.add(button1);
contentPane.add(button2);
contentPane.add(button3);
contentPane.add(button4);
contentPane.add(button5);
contentPane.setBackground(Color.orange);
addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
public static void main(String args[]) {
Interface window = new Interface();
window.setLocation(250,350);
window.setTitle("FlowLayout");
window.pack();
window.setTitle("Test");
window.setVisible(true);
public class ButtonHandler implements ActionListener {
public void actionPerformed( ActionEvent e )
System.exit(0);
Thanks alot! :)By default the content pane of the JFrame uses a Border Layout. So you should:
1) Create a JPanel
2) Set the layout of the JPanel to FlowLayout
3) add the buttons to the panel
4) add the panel to the content pane
5) add your text area to the content pane

Hi,
I have been facing this issue where the Topic Content Pane (<div>) overlaps the SideBar pane every time I try to open the Browser-Based AirHelp after it has been published on a server.
Although, if I view the same locally on my machine, it appears fine.
I'm using RoboHelp 10 to create the help and have the context sensitivity enabled for integrating the help with my software application.
I have also created the custom window for viewing help.
Now, considering the fact, that we are only using and testing our helpfile on the latest versions of Firefox and Chrome browsers with Flash enabled, this problem however, is not consistent. After getting published, on some machines it appears fine on both browsers and on some it only appears fine on any one of the browsers. Also, there are some machines, where the problem is seen on both browsers.
For Example:
When I try to view the helpfile after it has been published on a server, the following issues are observed:
On My Machine: Topic Content pane overlaps Sidebar pane on Chrome browser and on Firefox it appears fine.
Firefox version: 35.0.1, Chrome Version: 40.0.2214.115 m, Adobe Flash Player 11 Plugin Version: 11.7.700.202
On Another Machine: It appears fine on both browsers.
Firefox version: 35.0.1, Chrome Version: 40.0.2214.115 m, Adobe Flash Player 11 Plugin Version:11.6.6.2.171
Now take a look at these images:
(On Chrome) When Opened Locally:
(On Firefox) After Getting Published:
(On Chrome) After Getting Published:
Machine 1: Topic content overlaps TOC pane
Machine 2: Empty white space appears at the bottom (below footer)
After going through all the relevant information that could be found on your AirHelp forums, I couldn't find a solution.
This issue is very critical to me right now due to the upcoming documentation releases, and i need a resolution to this ASAP. Please Help.Hi Jeff,
I wrongly addressed it to Adobe. Any help through this forum would be appreciated. -
Problem uploading content into repository over WebDAV
Hi,
Sorry if the questions is responsed yet, but I haven't found it.
I am a new user in Oracle and Oracle XML DB. I have installed Oracle Database 10g Release 10.2.0.1. The dabase was created through the wizard and I have enabled 2100 and 8080 ports to work with FTP, HTTP and WebDAV. I have also created a new USER called DAVID with DBA permissions.
With this user I can upload 'not xml-content based' resource over FTP with different sizes but when I try to upload it over WebDAV I receive a message windows error and the resource is partially uploaded always with less than 500 bytes.
For example, I have upload a chm file with 19Mb. over FTP but I can't do the same over WebDAV.
What is the problem???? What I can do???
Thanks in advance,
DavidOK!, I can't created a bigfile tablespace, I specified only 1024Mb. but oracle tries to create a tablespace with 192Gb.
Finally, I have created a normal tablespace (initial size 500Mb), I have opened 2100 and 8080 ports to operate with FTP, WebDAV and HTTP.
Transfer over FTP works well but WebDAV continues with problem.
I have read the Bug 3703236 posted by mdrake, but I don't found any comment that helps me to solve the error.
As it say if I rename any file to xml, I can uploading to the repository over WebDAV without problem, but this file can't be renamed. For instance, in repository file system, rename msmsgs.xml to msmsgs.exe returns an error.
Also I have opened a TAR.
Any Idea?.
Thanks in advance,
David.

What exactly is the content pane and what is its purpose? I read this but am still quite confused. By the mini flow chart thing, do they mean that first i create a JFrame and then i get the contentPane for it and then i can add components like JPanel and JButton to the contentPane?
Or can i skip the getContentPane part and directly start adding stuff like JPanel and JButtons to the JFrame? if this is true, is it preferable to do this? are there any advantages or disadvantages to doing this instead of adding components to the contentpane?
Please help me understand this concept. Thank You.it's pane that contains the contents of the frame (or the rootpane, more specifically).
You create the JFrame first.
Then you add stuff to it's content pane. Since Java 5, you can add directly to the JFrame, and it puts things you add into the content pane for you. But it's the same thing.
Or you can add things to your own panel, then set the panel as the content pane of the frame.
You can't really add things to the JFrame directly without messing things up (and actually the API won't let you), cuz the rootpane is used for other things like menubars and the glasspane.
