Within an eclipse plugin I am trying to create a pop up window that activates within an editor and adds syntax to a string depending on the selection chosen in the pop up window. I have an editor class that extends AbstractTextEditor and within it I am trying to use a keylistener to pop up a window that contains a list of string manipulation functions and then when an item in the list is selected I want to replace some selected content with the new string returned from the method in the pop up window. When I attempt to do this (with the code in the 2 linked files), I receive the error below:

It seems that when autoupdate class tries to inform the editor class that a change has been selected it cannot manipulate the styledText variable. Does anyone know how to fix this?
The two files that contain this code can be reviewed at these links:
http://www.filedropper.com/markdowneditor
http://www.filedropper.com/autocomplete
The reason you are getting that exception is because when you make changes that are UI related with SWT you have to execute a runnable vis Display.syncExec(myRunable) otherwise that exception will occur.

what happened and how can i fix it? thanks !!! it has bothered me a long time...
I've got a similar issue. The solution was changing the theme!
Try the following:
Open JMeter -> Options -> Look and Feel -> Select any other theme other than Darcula (E.g. System theme).
Restart JMeter.
source: https://www.javaer101.com/en/article/5555703.html
Normally this happens when a Dependent jar is not present or in case if there is a conflicting jar with different implementation present.
Check this post
https://newspaint.wordpress.com/2013/08/21/jmeter-could-not-initialize-menufactory-class/
I was not able to open any file. Ctrl + O was showing same error. Problem is solve by changing theme.
This code works perfect when I press PLAY in netbeans, but when I build it and start the Jar file it will not.
private void SettingsMouseEntered(java.awt.event.MouseEvent evt) {
ImageIcon Setting = new ImageIcon(getClass().getResource("/pic/settings-icon.png"));
Settings.setIcon(Setting);
HooverBar.setText("Settings");
}
private void SettingsMouseExited(java.awt.event.MouseEvent evt) {
ImageIcon Setting = new ImageIcon(getClass().getResource("/pic/settings-icon-half.png"));
Settings.setIcon(Setting);
HooverBar.setText("");
}
private void SettingsMouseClicked(java.awt.event.MouseEvent evt) {
CardLayout card = (CardLayout)mainPanel.getLayout();
card.show(mainPanel,"gui5");
}
I can not figure out what I have done?
When i start the with "Java -jar Knowhow.jar" and move the mouse over the "settings" i get this error

Your images are not packaged within your jar. You need to change that.
I can't tell from the details of your question why that happens but the context is this:
getClass().getResource("/pic/settings-icon.png")
is loading the image from your classpath. That is from each element of the classpath. So your NetBeans classpath is different from the one of your java -jar command.
Have a look at the run configuration in your NetBeans to see your classpath there and map the classpath of your command to it.
how to check an element in jlist is already in another jlist
me using java swing.
my java Code:
lst3mdl-jlist model of 1st jlist
lst2mdl-jlist model of 2nd jlist
AbsntList-second jlist
prsntList-first jlist
lst2mdl=(DefaultListModel) AbsntList.getModel();/**/------------for checking if element already exists in jlist "listAbsnt"**
lst3mdl=(DefaultListModel)prsntList.getModel();
if(lst2mdl.contains(dsplList.getSelectedValue()||lst3mdl.contains(dsplList.getSelectedValue()))
//--do not allow multiple jlist entry
JOptionPane.showMessageDialog(null, "Element Already exist \n in one of other two List...!");
else {
lst1mdl=(DefaultListModel) dsplList.getModel();
int ind=dsplList.getSelectedIndex();
lst2mdl.addElement(dsplList.getSelectedValue());
if(ind!=-1)lst1mdl.remove(ind);
==========================

Go through the second list model and compare each item with selected element from the first model. If equals() returns true the second list contains the selected element.
Try to cast like this
ListModel lst1mdl = dsplList.getModel();
with out casting to (DefaultListModel).
Our applet source code is kind of spaghetti (written in 2000, Java 1.3 then) and we want to recompile it to Java 1.6 or 1.7.
When I'm testing it, most of the Swing is OK but after sometime, an Exception occurred, which is EDT exception. Specifically, when a drag event is done, a series of EDT exceptions appear.
Is this something to with coding the I/O part in ActionListeners because I've read that it is bad to code I/O operations in action listeners, which EDT executes when a action is performed.

This is the recurring exception

I guess it has something to do with the version of java plugin.
In java 1.6_10, a new version of this plugin is release, i just disabled the option in java found in control panel
Advance->Java Plug In ->Enable the next generation Java Plug in
When i disable this, this recurring error with no distinct behavior no longer appears.
I guess also it has something to do with our code written in the days of Java 1.3.
When the application is started, none of the rows is selected. But I would like to show that the first row is already selected.
How to do this? Do I need to set the color of a row in JTable?
Update:
I tried table.setRowSelectionInterval(0,0). I know it should work, but there is an error message:

You can do it calling setRowSelectionInterval :
table.setRowSelectionInterval(0, 0);
to select the first row.
It is an old post, but I came across this recently
Selecting a specific interval
As #aleroot already mentioned, by using
table.setRowSelectionInterval(index0, index1);
You can specify an interval, which should be selected.
Adding an interval to the existing selection
You can also keep the current selection, and simply add additional rows by using this here
table.getSelectionModel().addSelectionInterval(index0, index1);
This line of code additionally selects the specified interval. It doesn't matter if that interval already is selected, of parts of it are selected.
You use the available API of JTable and do not try to mess with the colors.
Some selection methods are available directly on the JTable (like the setRowSelectionInterval). If you want to have access to all selection-related logic, the selection model is the place to start looking
