JTabbedPane problem
Hello,
I have a JTabbedPane in which when I click a specific tab I launch
ProgressMonitor that shows progress of file that is being read. After
ProgressMonitor closes, focus on the tab screen is gained, but everything in
it is not showing (blank screen). Only after I click inside the screen will
I see what's in there. Does anyone have any suggestions?
code:
protected class SCDThread extends Thread{
public SCDThread(){}
public void run(){
/*
method that gets all data and has
ProgressMonitor
initialized and updated
*/
scr.addSizeChainScreen();
screen6.repaint();
screens.setSelectedIndex(5);
}
}
thanks,
Alex

knowing when JComboBox's data has changed
Hello, I have a custom JComboBox class where I set a ToolTip for each item. It works in times when I send a populated vector to the class. However, sometimes I need to send an empty vector and populate it later. How can I find out in custom JCB class when my vector has changed in number of elements? I tried to use ListDataListener, but had problems in implementing it. Also, I used ItemListener, but it works only when an item had been selected from JCB at which point it throws NullPointerException and then displays ToolTips correctly. thanks, Alex ___ Advanced-swing mailing list [EMAIL PROTECTED] http://eos.dk/mailman/listinfo/advanced-swing
ListCellRenderer
Hi,
I have a JTable in which I use JList as row header. I also alternate
colors of rows between gray and white. Now I need to color some of the
rows of JList in red. What I have is vector of rows that need to be
colored in red, in ListCellRenderer I loop thru this vector and compare
each element to index value of the renderer, if there is a match I set
background to red if not color other way. It seems to be working but in
a strange way. If I have 6 rows and need to color rows 6,4 and 2 the
will be only row 6 colored in red. If I make rows 4 and 2 to be colored
in red only row 4 is in red. It seems renderer colors only last row to
be colored. Don't know what to do. Any help is greatly appeciated.
** code below **
thanks,
Alex
class RowHeaderRenderer extends JLabel implements ListCellRenderer {
RowHeaderRenderer(JTable table) {
JTableHeader header =
table.getTableHeader();
setOpaque(true);
setBorder(UIManager.getBorder("TableHeader.cellBorder"));
setHorizontalAlignment(SwingConstants.LEFT);
setForeground(header.getForeground());
setFont(header.getFont());
}
public Component getListCellRendererComponent(JList list,
Object
value,
int index,
boolean
isSelected,
boolean
cellHasFocus){
setText((value == null) ? "" : value.toString());
for(int i = 0; i < unselectedRows.size(); i++){
if((String.valueOf(index)).equals(unselectedRows.elementAt(i))){
System.out.println("UNSELECT = " +
unselectedRows.elementAt(i));
setBackground(new Color(255,51,51));
setForeground(white);
}
else{
if(index % 2 != 0){
setBackground(white);
setForeground(Color.black);
}
else{
setBackground(gray);
setForeground(Color.black);
}
}
}
/*
if(index % 2 != 0)
setBackground(white);
else
setBackground(gray);
*/
return this;
}

JFrame question
Hi, When I call JFrame from my Applet, JFrame appears with a status bar saying 'Java Applet Window'. Is there a way to get rid off this status bar? thanks, Alex K ___ Advanced-swing mailing list [EMAIL PROTECTED] http://eos.dk/mailman/listinfo/advanced-swing
Re: JFrame question
Strange, because when my applet downloads a jar file, there is no status bar. Is that frame also regular JFrame or something else?

another JFrame question
Hi, When my Applet loads a JFrame, a user can click inside an Applet and JFrame will hide. Is there a way to keep JFrame visible until user closes it and if JFrame looses focus, JFrame is visible a top of Applet anyway? thanks, Alex ___ Advanced-swing mailing list [EMAIL PROTECTED] http://eos.dk/mailman/listinfo/advanced-swing

Re: Advanced-swing digest, Vol 1 #532 - 2 msgs
Thanks Frank,
So is MappedByteBuffer is really that fast? Also, I tried your suggestion of using
predefined Boolean object -- seems to save at most 3 seconds.

re:formatting string as a date
Actually got it working sort of... When I parse date string I have it as 04/03/03 so when done parsing I get year parsed as 0003 not 2003... ___ Advanced-swing mailing list [EMAIL PROTECTED] http://eos.dk/mailman/listinfo/advanced-swing
formatting string as a date
Hello,
I need to format a String that I get from database which is in form
04/03/03 to 4/3/2003. When formatting today's date, I do the following:
SimpleDateFormat formatter = new SimpleDateFormat("MM/dd/");
calendar.add(calendar.DATE,2);
int day = calendar.get(calendar.DAY_OF_MONTH);
int month = calendar.get(calendar.MONTH) + 1;
int year = calendar.get(calendar.YEAR);
String expire = month + "/" + day + "/" + year;
String twoDays = formatter.parse(expire);
But when I tokenize 04/03/03 and try to format is using:
SimpleDateFormat formatMonth = new SimpleDateFormat("M");
SimpleDateFormat formatDay = new SimpleDateFormat("d");
SimpleDateFormat formatYear = new SimpleDateFormat("");
StringTokenizer dateString = new StringTokenizer("04/03/03","/");
formatMonth.format(dateString.nextToken());
I get error:
java.lang.IllegalArgumentException: Cannot format given Object as a Date
at java.text.DateFormat.format(DateFormat.java:265)
at java.text.Format.format(Format.java:116)
What am I doing wrong here?
thanks,
Alex
