This works somewhat. The problem is that the mouseMoved event is only fired when the mouse is moved, so to get the scrollpane to scroll you have to constantly move the mouse.

When I programmatically add a component such as a list or button to a frame that I have used code to build then it will appear fine but I have an issue where the NetBeans frame that I have created and which is full of the NetBeans generated code, does not seem to respect the component that I add and thus it is not displayed.

I can for example, add a border to the panel through code which does show on screen when the project is run but a JButton or list for example will not. Why might this be?

	}
whichi s also not working ....

I want that when the user has added a record from the first Pane , and the moment he switches to Second Pane ,the just added datas to be displayed automatically.

When decreasing the size of the dialog, at a certain point, that is the horizontal space of the pane isn't enough anymore to display all buttons in a single row, wrapping comes into play.
It looks really bad!
How can I avoid this wrapping behavior in FlowLayout? Do I have to use another LayoutManager like BoxLayout?

Here it is
| - represents cursor/caret
[ ] - represents the JTextField and bold text is the text within it that is visible to the user.
<>Text in JTextField, but is not visible to the user.

< [Hello there m|y name is Andy ] I'm 100 years old>

What I want to be able to do is scroll through like this.
<H [ello there my| name is Andy I] 'm 100 years old>

so the caret stays in the middle and it also shifts the ScrollOffset in such a way that the caret is almost exactly in the middle.

What I'm ultimately trying to achieve is make a couple of characters right after the caret visible to the user.

Edit: A few more questions if no one has the answer to the one above... These might help me quite a lot.
1. Is there a way to find the position of the caret within jTextField in pixels from the left or right?
2. Is there a way to find pixels per character displayed in the JTextBox?]]> http://www.coderanch.com/forums/posts/preList/487322/2189835 http://www.coderanch.com/forums/posts/preList/487322/2189835 how to scroll by code
The situation:

I have a JTextArea embedded in a JScrollPanel which allows to scroll the text vertically.
The textarea serves as a kind of a log pane in my application, adding functional steps line by line to the area from top to bottom.

The problem:

Automatic scrolling is done in a way that always the first logs are displayed in the area. If the user wants to see the last logs he has to manually scroll down.

My question:

How is it possible to enable the last statements being displayed in the area instead of the first ones?

Kind regards,
Andy]]> http://www.coderanch.com/forums/posts/preList/487317/2189797 http://www.coderanch.com/forums/posts/preList/487317/2189797 limit text-input on a JTextField
In my Swing-GUI I have an input mask made up of several JTextField components.
How is it possible to configure those fields in a way, that they only accept up to a certain number of characters?
I tried to use setSize() and javax.swing.InputVerifier but neither of these worked in the way I want it.

Maybe it is necessary to write an own EventListener listening on and counting each character inserted in the field?

I'll try and express my problem more concisely.

I have invented a new component Histogram which extends JComponent.

I have an array[] of histogram objects.

I'm displaying a array[0] in a pane on my GUI, and I have a method update() which puts a new, different Histogram object in array[0]. I want the GUI to automatically reflect this change by displaying the new array[0] component instead of the old one.

How do I do this?

I am displaying image histograms on a user interface. Each histogram is represented by a class I wrote which extends JComponent. The painting is done the proper way through paintComponent and repaint() and it works great.

In my GUI constructor, I display the histograms.. 

       
pane7.add(graphs[0]);
pane7.add(graphs[1]);
pane7.add(graphs[2]);


And whenever I change the image, I call an update() method that contains the following line of code to update the histograms:

[code] graphs = plotter.plotRGB(currentImage); // Create histograms]]> http://www.coderanch.com/forums/posts/preList/487288/2189624 http://www.coderanch.com/forums/posts/preList/487288/2189624 addActionListener in HTML JButton?

I am using a StringBuffer to create a HTML label to display some text to my Swing app page, but I need links to another panel within this page.

Anyone have any ideas (presuming my explanation actually makes sense)

I am using below code to the read the data from the table. 

DefaultTableModel model = (DefaultTableModel)FileDetailsTable.getModel();

model.getValueAt(i, j);


I am unable to read the content of the cell which has focus. I mean if the user enters three data in three rows and the last column of the last row still has the focus with some user entered data, if I read this cell data it is coming as null.

Is this default behaviour of the JTable which can' t be changed or any fix for it?

Each of the tabItems controls a different table, so I have two tables in total.
Every 5 minutes I update the contents of both of the tables.
I searched for a way to customize the color of a selected item in a table, and I found information regarding SWT.EraseItem to make this possible.
I used this snippet: 
 
table1.addListener(SWT.EraseItem, new Listener() {
			   public void handleEvent(Event event) {
				      event.detail &= ~SWT.HOT;
				      if ((event.detail & SWT.SELECTED) == 0) return; /* item not selected */
				      int clientWidth = table1.getClientArea().width;
				      GC gc = event.gc;
				      Color oldForeground = gc.getForeground();
				      Color oldBackground = gc.getBackground();
			      gc.setForeground(red);
				      gc.setBackground(red);
				      gc.fillGradientRectangle(0, event.y, clientWidth, event.height, false);
				      gc.setForeground(oldForeground);
				      gc.setBackground(oldBackground);
				      event.detail &= ~SWT.SELECTED;
				   }
				});


Here is my problem:
When I have selected table2 (tabItem2), and my tables are updated, the first table, table1 gets focus, you can only see table1, though the selected tabItem appears to be tabItem2.
I hope my problem is clear to you, so when updating the tables, the eraseItem listener causes the first table to appear even if the second table is selected.]]> http://www.coderanch.com/forums/posts/preList/487164/2189129 http://www.coderanch.com/forums/posts/preList/487164/2189129 Reporting Tool The basic idea is to connect to a database , get some tables and drag and drop them onto the report where the data in the tables will get displayed .
