JMenuItem icon prboblem
Hi,
I implemented some JMenuItem in my application. Some of them have icons, some don't. How can I justify their position for those ones without icons??
Currently it's like:
[ ] item1
[ ] itme2
item3
[ ] item4
thanx heaps
Create an empty icon, one that has a size but doesn't paint, and add it to the ones you need justified. That's how I solved the problem for my app.

JMenuItem icon/Text verticle alignment question
hello,
can some one help with my question:
I got 5 JMenuItems in a JMenu, some JMenuItems have icon, some not, I want to align them with icon and text in a neat format, like those in Sun's Forte IDE's Menu:
but I can only do it like this:
icon1 open..
save As..
icon2 new..
Exit..
(above each line represent a JMenuItem, I need to make "save as" ,"Exit" to in line with "open" and "new" in verticle direction,NOT with the icon)
sb suggest always set an icon for each JMenuItem, set an transparent Icon for alignment those without icons.
but this sounds not so attractive, are there any other ways? thanks a lot.Create a method to do the icons. One can have one parameter (menu text) and the other could have two parameters (icon name, menu text). Have the one with just one parameter set up a default transparent icon.

overriding the painting method.
But I belive that the first suggestion is faster. -
JAWS does not always read Swing menus
I have come across a problem that involves JAWS 4.51 and Java menus in Internet Explorer.
I have a Java application that has a JMenuBar. The menu bar contains several JMenus that in turn contain several JMenuItems.
When navigating through a menu, JAWS reads every JMenuItem. However, once a disabled JMenuItem is reached, JAWS no longer reads the JMenuItems below the disabled one in the open JMenu.
The problem occurs only in Internet Explorer on "plain" menu items that follow a disabled menu item. The problem does not affect "complex" menu items, such as those that open sub menus.
I can only reproduce this problem in Internet Explorer 6. Netscape Communicator 7, Web Start clients and a command line launch do not suffer from this problem. Also, JAWS 4.02 is fine as well; only 4.51 has this problem.
Attached at the end is a sample application that recreates the issue. You'll notice in the sample application that JAWS will not read "A check box menu item" and "Another one" while it will read "A submenu."
Does anyone have a solution to this? Thanks a lot!

Here's the applet:

</applet>
</body>
</html>Unfortunately the menu items are fully accessible (or so our internal accessibility tool claims). It doesn't seem to be a problem on that level, but I was hoping that perhaps something else was interfeering.
As for the JTable reading the previous cell, I've notice that it reads the last non-empty cell (regardless of whether it was the previous cell or not) when clicking or moving with the arrow keys to an empty cell. It works fine when clicking or moving to non-empty cells.
I don't have any empty cells in the actual application so I did not try to fix it. My suspicions are that either an event is not being fired or the selection position is not being updated on the empty cells. -
Error with - addStylesToDocument(doc); please help
Hello, this is my unfinished code for a simple program I am writing. Basically I have a menu and buttons, and am looking to add a JTextPane. I think I have all the code there, except when compiling I am having an error with line addStylesToDocument(doc); if I comment this out then nothing happens but the program runs as normal (before I added the JTextPane code) the error I am getting is "non-static method addStylesToDocument(javax.swing.text.StyledDocument) cannot be referenced from a static context" this makes a little sence to me but not enough to be able to correct it as I am pretty much a beginner...
If anyone has any suggestions to fix this I would appreciate your input.

I see that you have run out of helpfulness for this session, What the ....? I just told you to add your jtextfield to a jpanel or some other visible component to be seen.
it is getting late here I will take my business elsewhere tomorrow rather than waiting up for a response which shows you realllly need to find something better to do! And thanks for the help earlier. That was actually useful whereas this wasn't, I'm sure you knew that already,You know that we are all volunteers here. Any time spent here helping you is time away from our friends and families.

I am using JAWS 6 with JDK 1.4.2_06 and Access Bridge 1.2.
If I add Menuitems to a JMenu which is added to the menubar everything works as expected. One of the menu items is another JMenu, a sub-menu. When JAWS reads this it speaks "submenu" indicating that there is a sub-menu to the right of the current menu item. However, If I attached the exact same menuitems to a JPopupMenu,
JAWS never speaks "submenu" so the user has no iindication that there is a sub-menu to the right.
I've taken the attached code from "The JFC Swing Tutorial - Second Edition" and tweaked it slightly so the menubar and popup menu contain the same items.
It seems as if the accessibility api is expecting the first set of menu items to be attached to a menu parent.
If worked around this for now by adding another top level menu to the popupmenu to which I add the menuitems.
Is this a Java or JAWS bug ?

Setting icon for the JMenuItem
I am trying to set the Icon for the JMenuItem and not able to do so.
I have the Images directory in the classes which has all the images. Is this the way to give the dir path. When do I give '\' and when do I give '/' or'//' or'\\'? Thanks.
I gave
JMenuItem mnuitmFileNew = new JMenuItem(new ImageIcon("Images//new.jpg"));
and later in Jbinit() method I have this.
mnuitmFileNew.setMnemonic('N');
mnuitmFileNew.setText("New");
mnuitmFileNew.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(ActionEvent e) {
mnuitmFileNew_actionPerformed(e);
});Hi,
I'm not sure if you've seen this yet:

If you still have any questions please post again.

I want to have icons on my menu. I am using the Windows look and feel.
On most native windows menus the icons appear in a separate column on the left. When I use icons in java menus they appear much too far to the right and the text doesn't align properly with the icons unless I move the text using Insets. There has to be a better way that gets the icons further left and the text aligned. Here is my code...
private void createMenuItem(String text, int mnemon,
KeyStroke accel, JMenu owner, Icon ic)
JMenuItem temp=null;
if (ic == null)
temp = new JMenuItem(text,mnemon);
Insets in = temp.getInsets();
in.left += 20;//icon width is 20
temp.setMargin(in);
else
temp = new JMenuItem();
temp.setHorizontalTextPosition(SwingConstants.RIGHT);
temp.setText(text);
temp.setMnemonic(mnemon);
temp.setIcon(ic);
if (accel != null)
temp.setAccelerator(accel);
temp.addActionListener(this);
if (ic != null) temp.setIcon(ic);
owner.add(temp);
}I have had this problem too. The misaligned text looks terrible.
Here is the solution I found, using an EmptyIcon class :
http://www.javapractices.com/Topic169.cjp
There is an example Swing app implementation on the same site which uses this technique. You may browse the javadoc, which has links to source code :
http://www.javapractices.com/Topic170.cjp
Example of a class in the example app which uses this technique :
http://www.javapractices.com/apps/stocksmonitor/javadoc/stocksmonitor/ui/EditUserPreferencesAction.html
Clicking on a class or method name will link to the source code....

I am building a JMenu, using JMenuItem, I want to show a Icon "V" in JMenuItem, so the user can click on it to see more options, just like we get in windows 2000 , in your start menu. where it only shows the menus which we have recently accessed, and hide others.
Is there any standard java class for it or i will have to download a image and create a Icon from it and use it in JMenuItem.
I dont know if any of the Implementing Classes of Interface Icon can be used for itIf u want a icon then there is a consturctor available which takes in a Icon.
JMenuItem( String, Icon )
but if u want just to underline V then u can set the accelerator using setAccelerator method.
menuItem.setAccelerator( KeyStroke.getKeyStroke(
KeyEvent.VK_F, Event.CTRL_MASK ) );
here it is set for cntrl + F
Hope this would help

I'm working on a project that has so emulate a 16 bit RISC microprocessor. And I decided to build an Applet and I created a menu for the applet. The problem is that I can't add icons to the menu items. I tried to add icons for a menu in a frame (stand-alone) application and it worked. But I can't in the applet.
I tried using the following code:
ImageIcon icon= new ImageIcon("icon.gif");
menuitem.setIcon(icon);
And it doesn't work!! :-(
Why? Or you can't use icons in applet menus?Let's assume you have the icon in the same directory
as the html file the applet's in on the server:
new ImageIcon(new URL(getDocumentBase(), "icon.gif"));
I think just the string argument has to be a file.Thanks a lot! I should have tried that... but I forgot that I had to work with images in an applet. That works.. -
Disabled JMenuItem doesn show animated gif
Hi there
I would like to have a popup menu with actions that are enabled after they have finished with some background task taking some time. Basically this works fine for the enabling action on a shown popup. However, adding an animated gif as the icon or disabled icon does not show it in disabled state. In enabled state it works perfect. Please have a try with the sample code. You should see the disabled item for 2 secs and the icon is not showing up. After being enabled, it does. Invoking the menu again shows the animated gif in its last state left, but not moving any more.
I guess, repaints are not done appropriately in disabled state... Any ideas how to solve that would be highly appreciated :-)
Actually I used the icon at http://mentalized.net/activity-indicators/indicators/pascal_germroth/indicator.white.gif
Cheers
Daniel

}Edited by: daniel.frey on Apr 22, 2009 7:50 AMThe problem is that you are causing the EDT to sleep, which means the GUI can't repaint itself. Read the section from the Swing tutorial on Concurrency to understand what is happening.

How to set icon on MenuItem, but not in JMenuItem?

You are right.It's not possible to set icon on menuItem.
I am talking about SystemTray in which I added PopupMenu with MenuItem.
but I need MenuItem with icon.Is there another way to solve this problem?Nope, just because you're adding a PopupMenu to a TrayIcon does not change the fact that MenuItems cannot have icons.
