RE: Update the JScrollPane in another thread

[Song, Mingjian]

Hi, Yuan Bing,

 

If you want to always show the last row of a JTable in the JScrollPane.

You can try the scrollRectToVisible() method in the JTable class.

It goes like this ...

 

//assume the name of the JTable is "table".

 

// first cell last row. check for empty table if necessary.

Rectangle rect = table.getCellRect(table.getRowCount()-1, 0, yes);

 

// I believe this will fire the proper event to scroll the viewport.

table.scrollRectToVisible(rect);

 

If you are calling this routine from a non GUI thread, you may want

to wrap it in a SwingUtilities.invokeLater(). I never tried it myself

though.

 

Have a nice hoiliday,

 

Song Mingjian

Subject: Update the JScrollPane in another thread

Hi,

 

I want to update the JScrollPane in another thread, like this:

------------------------------------------

  public void newMessage(ChargedCdr ccdr) {  // will be invoked in a non-event-dispatching thread

    ...
    model.fireTableDataChanged();        //of a table within jScrollPane1
    jScrollPane1.getVerticalScrollBar().setValue(jScrollPane1.getVerticalScrollBar().getMaximum());
  }
------------------------------------------

The function I wanna get is to move the scroll bar to the end of the table whenever model's data changed(by another thread), and it could work, but some times just not to the end of the table, but still has 1 line left below.

 

Maybe I misused the setValue, because it was not in a event-dispatching thread, am I right?

 

Then what is the right way to do this?

 

regards,

Yuan Bing
