jhon max

is it possible to make, for example 2 different L&F in a two components within the same window?
example "Metal" for a button and "Nimbus" for another button.. I dont know how to implement the .setUI() button of every swing component. i read the API and it says that .setUI() and .getUI(), sets and returns the look and feel of a components, i just dont know how.

I mean the header on the west corner of the table, the header that represents each row

sorry sir

no sir...

I didnt mean to say that I didnt check it, actually it helped me a lot..Im just getting too confused on the resources that Im getting from google.. sorry for using such an informative words, but english is not my native language , im sorry,

what I mean with "no sir" ,- I didnt know what should I do In the method that you gave me to make a selection focus,

again, Im so sorry, I didnt intend to waste your effort, sorry for using such a word...

no sir...

to make the highlight(the selection focus) i have to click first the table so there will be a selection focus in any of the cell, so If i search the matching value it will highlight it,,

but i have to click first the table... is there any way to make a default selection focus ?

In pseudo code
1) User types something
2) Figure out which cell has a match
3) Scroll to the required cell.

tnx for the psedocode sir,

table.getCellRect ,, this one was reffering to the cell I never thought of that thank you for that,

I solved that part.. But the problem now is the highlight of the specific cell, those codes that I posted was just for illustrating the problem, but in my original code
I have a rendered table with Image background, when I clicked(selected) a cell I dont see a highlight but the foreground color of the text in the cell changes(Im fine with that),

what I want now is the selection focus,

For example I have already searched the value, the program will automatically highlight that cell , how can I accomplish this one?

heres a program for the auto scroll.
I tried to get some idea on this program but I only know how to scroll automatically at the "bottom", what I need now, is to specify the view of the scroll according to the searched value.. I tried to search and play with Viewports, but Im still stuck with this problem, I'm not also sure If the viewport can help me with this... please I need more help...

I have some problem with searching a value(focusing on the selected searched row).

when I run the program the table doesnt have the selection focus (if that is the right term to say). I have to click first in any of the cells in the table, so the selection will be on focus.
(is there any way to make a default selection focus in a JTable?)


when the program searches for the equivalent "name" input in the text field, it highlights it but the "scroll" doesnt scroll down to view the part where that value resides

oh my... Is there any simple way to resolve this sir.??

okButton.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { value = textField.getText(); } });

but I still get a null value

the whole changes I made

but Im stuck with returning a value.. anyway I left some of the method as void to be easily compiled, but lets assume that it returns a String value...
what I want is if I press the button it will return a value from another class that calls that method... please I need help ..

public class JTableWithMouseListenerextends extends JFrame { private JTable table; private JPanel lowerPanel; private JScrollPane scroll; public JTableWithMouseListener() { initializeInventory(); } private void initializeInventory() { lowerPanel = new JPanel(); lowerPanel.setLayout(new BorderLayout()); final String[] columnNames = {"First", "Second", "Third", "Fourth"}; final Object[][] data = new Object[100][columnNames.length]; table = new JTable(data, columnNames); table.addMouseListener(new MyMouseAdapter()); scroll = new JScrollPane(table); scroll.setBounds(0, 0, 1395, 400); lowerPanel.add(scroll); getContentPane().add(lowerPanel); setDefaultCloseOperation(EXIT_ON_CLOSE); setTitle("Inventory Window"); pack(); setLocationRelativeTo(null); setVisible(true); } // class for implementing the mouse listener private class MyMouseAdapter extends MouseAdapter { public void mousePressed(MouseEvent e) { if (table.equals(e.getSource())) { int colIdx = table.columnAtPoint(e.getPoint()); int rowIdx = table.rowAtPoint(e.getPoint()); System.out.println("Row: " + rowIdx + " " + "Colulmn: " + colIdx); } } } public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable() { public void run() { new JTableWithMouseListener(); } }); } }

In this sample code you can see that I can only display the selected row and columns (cells) by clicking a cell.

My question is what action/event should I implement for displaying the selected cell by pressing the 4 directional arrows?

please I need help with this.. thank you very much

thank you.!

Im having some problem regarding with displaying the selected column header, Im getting -1, how am i supposed to resolve this.. thanks!

I beg your pardon.. im sorry to make the title unclear or irrelevant to the posted code, .. what i want in my JTable is when i click a row, that row will be highlighted, but in this case i have an image Background in my Jtable,
Im having problems with that,

When I tried to remove the background , I can easily do that specific thing that I want, the whole row that I clicked was Highlighted, because of the background I cant see the highlight,
but I need to apply an Image Background in my JTable...

Is there anything to do with TableRenderer?
