Inserting imageicon in jtable

Hi,
I want to insert imageicon in Jtable using AbstractTableModel.
Please help me out from this.

Use custon Cell RendererThere's no need to use a custom cell renderer.
Just override getColumnClass method of your model to return ImageIcon.class for the appropriate column, and add the imageicon to the model.

table1.getValueAt(table1.getSelectedRow(),0)you are getting the value of a selected row... or if you want you can just use a loop..
for(.....){
table1.getValueAt(x,y);
}I think you know INSERT STATEMENT.. here on it just string concat

Rendering ImageIcons in JTable cells

Hi folks, anyone know how to:
1. add a single ImageIcon to a JTable and then display the table, then add another imageicon and display again etc. etc...
... and...
2. take a vector of imageicons and construct a JTable directly from this?
These involve working with areas of Java I am, frankly, totally unfamiliar with and I'm actually really stuck with TableCellRenderers, JComponents, Repaint etc. so could use some assistance!
Thank you all kindly,
Jam

JDK1.3 comes with a demo that shows the use of all Swing components. The table demo has a column displaying images. The code is included so you can see how it is done:

Need to use vector to insert data into JTable?

hi
i'm trying to insert data from mssql 2000 into JTable. The number of columns are fixed, but the number of rows are not, since it will depend on how many data retrieved from the database.
The documentation says that vector class implements a growable array of objects, and I've seen some examples using vector such as from http://forum.java.sun.com/thread.jspa?forumID=57&threadID=238597 .
I would like to know, in my case, do i need to set my column and row to use vector? or should i only set rows to use vector ? (since the row size will vary, while the column size will stick to 6).

Because your JTable operation will be done on a table model, the selection of the initial data
structure for the model is almost non-issue. In other words, whatever will do.
See the javadoc for the DefaultTableModel class, which you will eventually use, especially the
construcotr part.

Inserting cell inside JTable cell

Unable to insert JRadio in JTable.

Hi All,
I'am very new to swing development and working on JTable which should contain 4 columns (Index,RadioButton,Device Name and Device Number).The rows are added dynamically.I have written classes MyTableModel, MyTableRadioButtonRenderer and MyTableRadioButtonEditor which I'am using in my main class.
The problem is that when I execute the main class I get a Table view with all other values as desired but the values returned by the radiobutton in the second column is null (i.e my second column is filled with empty spaces).I have tried several ways but failed in displaying the table with radiobuttons.
Can anyone please guide me through this.

<sigh>
Apparently the profusion of topics returned in the forum search has left us baffled...
Now... again I say - RTFA..
1) A JTable uses single instance components to render its data - this only makes sense as a table containg thousands of records could become a little heavy if each cell was a label.... so in order to keep things manageable it specifies a RENDERER for each data type, determined by class, which is iterated through each value to produce an on-screen image which is NOT a component. That's all the cell is, an image. NB! This is CLEARLY stated in the API. So, as previously stated, providing a JRadioButton to display a BOOLEAN value is absolute pants... it goes against the whole purpose behind this functionality and does nothing for performance. If you would like the BOOLEAN value displayed as a JRadioButton, you would need to sub JRadioButton and implement TabelCellRenderer... then simply call:
myTable.setDefaultRenderer(Boolean.class, myCustomRadio);Now, each time the table encounters a BOOLEAN value, it will use your specified renderer to draw an IMAGE of a JRadioButton with its state determined by the BOOLEAN value.. , (NB! this is an IMAGE not a JRadioButton).
2) The same goes for your EDITOR. Again, creating a billion unique components to edit each cell is quite obviously senseless... so each type has its own EDITOR specified..., the editor returned when you click on an editable cell is specific to that type. So... your choices are to create another subbed JRadioButton to handle this, or have the RENDERER perform this function for you, (which it can do as it isn't tied to any particular cell). Thus:
myTable.setDefaultEditor(Boolean.class, myCustomRadio);Will provide you with the required functionality...
Take to heart the comment about the API - all of the above is there and more....
With that said, can you see why using a ButtonGroup did not work..?

Help with updating imageIcon in JTable

Hi All
Please I am hoping that some out there will know what is going on with this
I am setting a Cell with a ImageIcon with this code
        Object[] data = {
            rSet.getString(1),
            new ImageIcon("imagesTest/" + "check" + rSet.getString(2) + ".png"),
            rSet.getString(2),
            "yes",
            rSet.getString(3)};
        model.addRow(data);and this work fine as I have this set to the table
      public Class getColumnClass(int c) {
        return getValueAt(1, c).getClass();
      }Now I want to update the ImageIcon with a new image that I create
and I am trying to set the new ImageIcon to the cell with this code
      model.setValueAt(new ImageIcon("imagesTest/" + "check" +table.getValueAt
(table.getSelectedRow(), 2) +".png"), table.getSelectedRow(), 1);but it does not want to paint it
I have tried
repaint();
super.repaint();
revalidate();I have also tried reloading the data by removing all the rows in the model with this
    model.setRowCount(0);
   then reloading the data.
It seams like it holds ImageIcom in memory or something .
Has anyone got an idea on how I can get this to work
p.s I don't have the full code to show as it is hard to pull it apart.
I hope I have given enough code to so you what is going on.
Thanks for any insight into this
Craig

You should write an appropriate cell renderer.
If the cell is defined editable, you'd also need cell editor.

Need help with inserting rows in ResultSet and JTable

hello Guru!
i have inserted a row in my result set and i want that my table shows this row promptly after i have inserted it in my result set...
but when i use following code for my resultset:

Seeing Database Changes Made Internally and Externally
This section discusses the ability of a result set to see the following:
its own changes (DELETE, UPDATE, or INSERT operations within the result set), referred to as internal changes
changes made from elsewhere (either from your own transaction outside the result set, or from other committed transactions), referred to as external changes
Near the end of the section is a summary table.
Note:
External changes are referred to as "other's changes" in the Sun Microsystems JDBC 2.0 specification.
Seeing Internal Changes
The ability of an updatable result set to see its own changes depends on both the result set type and the kind of change (UPDATE, DELETE, or INSERT). This is discussed at various points throughout the "Updating Result Sets" section beginning on , and is summarized as follows:
Internal DELETE operations are visible for scrollable result sets (scroll-sensitive or scroll-insensitive), but are not visible for forward-only result sets.
After you delete a row in a scrollable result set, the preceding row becomes the new current row, and subsequent row numbers are updated accordingly.
Internal UPDATE operations are always visible, regardless of the result set type (forward-only, scroll-sensitive, or scroll-insensitive).
Internal INSERT operations are never visible, regardless of the result set type (neither forward-only, scroll-sensitive, nor scroll-insensitive).
An internal change being "visible" essentially means that a subsequent getXXX() call will see the data changed by a preceding updateXXX() call on the same data item.
JDBC 2.0 DatabaseMetaData objects include the following methods to verify this. Each takes a result set type as input (ResultSet.TYPE_FORWARD_ONLY, ResultSet.TYPE_SCROLL_SENSITIVE, or ResultSet.TYPE_SCROLL_INSENSITIVE).
boolean ownDeletesAreVisible(int) throws SQLException
boolean ownUpdatesAreVisible(int) throws SQLException
boolean ownInsertsAreVisible(int) throws SQLException
Note:
When you make an internal change that causes a trigger to execute, the trigger changes are effectively external changes. However, if the trigger affects data in the row you are updating, you will see those changes for any scrollable/updatable result set, because an implicit row refetch occurs after the update.
Seeing External Changes
Only a scroll-sensitive result set can see external changes to the underlying database, and it can only see the changes from external UPDATE operations. Changes from external DELETE or INSERT operations are never visible.
Note:
Any discussion of seeing changes from outside the enclosing transaction presumes the transaction itself has an isolation level setting that allows the changes to be visible.
For implementation details of scroll-sensitive result sets, including exactly how and how soon external updates become visible, see "Oracle Implementation of Scroll-Sensitive Result Sets".
JDBC 2.0 DatabaseMetaData objects include the following methods to verify this. Each takes a result set type as input (ResultSet.TYPE_FORWARD_ONLY, ResultSet.TYPE_SCROLL_SENSITIVE, or ResultSet.TYPE_SCROLL_INSENSITIVE).
boolean othersDeletesAreVisible(int) throws SQLException
boolean othersUpdatesAreVisible(int) throws SQLException
boolean othersInsertsAreVisible(int) throws SQLException
Note:
Explicit use of the refreshRow() method, described in "Refetching Rows", is distinct from this discussion of visibility. For example, even though external updates are "invisible" to a scroll-insensitive result set, you can explicitly refetch rows in a scroll-insensitive/updatable result set and retrieve external changes that have been made. "Visibility" refers only to the fact that the scroll-insensitive/updatable result set would not see such changes automatically and implicitly.
Visibility versus Detection of External Changes
Regarding changes made to the underlying database by external sources, there are two similar but distinct concepts with respect to visibility of the changes from your local result set:
visibility of changes
detection of changes
A change being "visible" means that when you look at a row in the result set, you can see new data values from changes made by external sources to the corresponding row in the database.
A change being "detected", however, means that the result set is aware that this is a new value since the result set was first populated.
With Oracle8i release 8.1.6 and higher, even when an Oracle result set sees new data (as with an external UPDATE in a scroll-sensitive result set), it has no awareness that this data has changed since the result set was populated. Such changes are not "detected".
JDBC 2.0 DatabaseMetaData objects include the following methods to verify this. Each takes a result set type as input (ResultSet.TYPE_FORWARD_ONLY, ResultSet.TYPE_SCROLL_SENSITIVE, or ResultSet.TYPE_SCROLL_INSENSITIVE).
boolean deletesAreDetected(int) throws SQLException
boolean updatesAreDetected(int) throws SQLException
boolean insertsAreDetected(int) throws SQLException
It follows, then, that result set methods specified by JDBC 2.0 to detect changes--rowDeleted(), rowUpdated(), and rowInserted()--will always return false with the 8.1.6 Oracle JDBC drivers. There is no use in calling them.
Summary of Visibility of Internal and External Changes
Table 12-1 summarizes the discussion in the preceding sections regarding whether a result set object in the Oracle JDBC implementation can see changes made internally through the result set itself, and changes made externally to the underlying database from elsewhere in your transaction or from other committed transactions.
Table 12-1 Visibility of Internal and External Changes for Oracle JDBC

For implementation details of scroll-sensitive result sets, including exactly how and how soon external updates become visible, see "Oracle Implementation of Scroll-Sensitive Result Sets".
Notes:
Remember that explicit use of the refreshRow() method, described in "Refetching Rows", is distinct from the concept of "visibility" of external changes. This is discussed in "Seeing External Changes".
Remember that even when external changes are "visible", as with UPDATE operations underlying a scroll-sensitive result set, they are not "detected". The result set rowDeleted(), rowUpdated(), and rowInserted() methods always return false. This is further discussed in "Visibility versus Detection of External Changes".
Oracle Implementation of Scroll-Sensitive Result Sets
The Oracle implementation of scroll-sensitive result sets involves the concept of a window, with a window size that is based on the fetch size. The window size affects how often rows are updated in the result set.
Once you establish a current row by moving to a specified row (as described in "Positioning in a Scrollable Result Set"), the window consists of the N rows in the result set starting with that row, where N is the fetch size being used by the result set (see "Fetch Size"). Note that there is no current row, and therefore no window, when a result set is first created. The default position is before the first row, which is not a valid current row.
As you move from row to row, the window remains unchanged as long as the current row stays within that window. However, once you move to a new current row outside the window, you redefine the window to be the N rows starting with the new current row.
Whenever the window is redefined, the N rows in the database corresponding to the rows in the new window are automatically refetched through an implicit call to the refreshRow() method (described in "Refetching Rows"), thereby updating the data throughout the new window.
So external updates are not instantaneously visible in a scroll-sensitive result set; they are only visible after the automatic refetches just described.
For a sample application that demonstrates the functionality of a scroll-sensitive result set, see "Scroll-Sensitive Result Set--ResultSet5.java".
Note:
Because this kind of refetching is not a highly efficient or optimized methodology, there are significant performance concerns. Consider carefully before using scroll-sensitive result sets as currently implemented. There is also a significant tradeoff between sensitivity and performance. The most sensitive result set is one with a fetch size of 1, which would result in the new current row being refetched every time you move between rows. However, this would have a significant impact on the performance of your application.

Animated .gif in JTable cell

Hi -
I have an actual animated .gif that I would like to display in a JTable's cell. By 'actual animated .gif', I mean that it is one file that is animated, and not a succession of files that I would loop through to look like animation.
I have edited the following code that I found in a previous post. My .gif does display in the JTable and animates only ONCE. Once it animates once, it stops. How can I cause it to keep looping through and repeating the animation?
Thanks!
Kelly

return (flags & (ALLBITS | ABORT)) == 0;
public static void main(String[] args)
AnimatedIconTableExample frame = new AnimatedIconTableExample();
frame.addWindowListener(new WindowAdapter()
public void windowClosing(WindowEvent e)
System.exit(0);
frame.setSize(300, 150);
frame.setVisible(true);

I've heard of that problem before... I think it has something to do with how the image is loaded. I found an example of how Sun does animated gifs here: http://java.sun.com/products/java-media/2D/samples/suite/Image/DukeAnim.java
I hope it helps.

Transfer Data from a JTable to the table model

Hi
I' looking for a simple method to transfer the last user input in a table to the table model.
For example:
In a Dialog the user insert in a JTable a few values and leaves with OK. But the last input is not saved in the model. It is just saved after selecting a new field in the JTable before leaving the Dialog.
Is there a call to transfer all input to the model?
Thanks
Guido

class MyJTable extends JTable (
public boolean validateInput() {
if(isEditing()) {
return cellEditor.stopCellEditing();
return true;
Call this method whenever you want the input value to be stored in the table model. The return value can be false if the input isn't valid, this will depend on the cell editor.
The idea is:
Ask if the table has an editor activated. (isEditing())
If so, request the editor to store the value in the model.
I haven't prouved the code, sorry, but I hope you get the idea and helps.

Insert Table into jScrollPanel?

I want to insert a new JTable into the jScrollPane.
It works, but the Table wont appear in the middle.
Here is a Picture of the Layout:
http://img254.imageshack.us/my.php?image=hujodstworx9.jpg
Can someone plz tell me howto insert into jScrollPane and make the right Layout for the Table????

Der funktionierende Code sieht so aus.
          //delete The Table from Frame and Create a new jTable
          remove(jTable1);
          jTable=getJTable1();

          viewport.setViewPosition(viewport.getLocation());
          SwingUtilities.updateComponentTreeUI(this);This crazy Code works, the "viewport" Object has Methods to Move the Content inside tthe jScrollPane.
I Said Java to Place jScrollPane4 to the place of jScrollPane4??????? Dont know why it works, but it does.

TableCellRenderer for a JTableCell contains imageIcon

Hi, all.
I am writing a TableCellRenderer for a column in JTable which contains imageIcon. It sets the background of the cell to a specific color. It worked fine when the column's datatype is string. But when the datatype of the cell is an imageIcon, the setBackground method somehow overlaps the imageIcon, basically, I can't see the image Icon anymore. As I understand, while the datatype is imageIcon, the JTable basically Centers the imageIcon on a JLabel, then when I set the background of JLabel to a color, it should work, right? Here is the code, any help would be greately appreciated.
