List of 2 different objects
Hi! I have a Binary tree object that works fine.
Now I was asked to define a Forest that should look like this:
A Forest is defined by a NameProc (the name of the process that generates the Forest) and a finite list of given states s1,s2,..,sn, each state generates a Binary tree.

rectangles in Swing JPanel
Hi! I'm trying to draw some filled rectangles in a JPanel, should I define a paintComponent like this?
public void paintComponent( Graphics g) {
super.paintComp onent(g);
g.setColor(Colo r.blue);
g.drawRect(10, 10, 80, 30);
g.drawRoundRect (100, 10, 80, 30, 15, 15);
Or is there any other way to do it? maybe using some Swing component, for example the JTextField is like a rectangle and... -
don't reset check box
Hi! this might be so easy but I can't make it work: I just have a check box, the user selects it, then the user exits that form, when the user comes back to the form I need the check box to be as the user left it.
I defined the check box not initialized but if I select it, then leave that form and come back the check box appears unselected. -
Yes, you are right, thanks, the file I'm searching it's located in a fixed folder in MyApplication folder, but MyApplication folder will be distributed to other users that I don't know where are going to locate it. To find the path to MyApplication folder I'm using this:
String wd = System.getPrope rty("user.dir") ;
and it's working ok, what do you think about it?
ThanksLeave a comment:

find color for end user
Hi! I defined this background color for a JTable and it works fine:
Color Pigment;
Pigment = new Color (242, 232, 232);
It's gray as I tested it in here :
http://www.shodor.org/stella2java/rgbint.html
and as can be seen for the proporcions of red, green and blue. And looks gray (exactlly the gray I'm looking for) when I run the application in my PC and others.
But when my end user tested it in it's... -
THANKS.

$ character in .CLASS files
Hi! I need to start to work in a medium-size application (500 classes) that some students have been developing for up to 2 years, the first thing I found is that for each .java file there are many (up to 30) .CLASS with the same name but with a $ and a sequencial number before the extension. For example:
DlgOpcTFreq.jav a
DlgOpcTFreq.cla ss
DlgOpcTFreq$1.c lass
DlgOpcTFreq$2.c lass
DlgOpcTFreq$3.c lass

That will work! Thank you very much Jos...Leave a comment:

set 4 positions in BoxLayout
Hi! I hope someone could help:
I defined a BoxLayout JPanel because I need to show in this order:
a checkbox
a textfield
another checkbox
another texfield
and this works fine:
JPanel jPanelBoEx = new JPanel();
jPanelVars.add( jPanelBoEx, BorderLayout.LI NE_START);
jPanelBoEx.setL ayout(new BoxLayout(jPane lBoEx, BoxLayout.PAGE_ AXIS));
jPanelBoEx.add( jchkbox1);... -
I've been thinking the first solution: to define it as a JDialog.
And now it works fine, but I need to add everything else (buttons, labels, functionality) from the JPanel to the JDialog.
I tried the setContentPane to "copy" everything from the JPanel to the JDialog but it's not working...It shows the JDialog as if I had done nothing...
...Code:private JPanel contentPane; dlg = new MyDialog(this);

But the JPanel prints the message "I'm here" before closing it
and the JDialog prints the message after closing it.
I need the JPanel to print the message after closing it, how could I do that?Leave a comment:

Thanks, then as I understand I need the JPanel to be modal, the JDialog is modal and that's why it shows the message after closing it. The JPanel is not modal and that's why it does not wait until I close it to print the message.
So as I understand I should have to make the JPanel modal, but dlg.setModal(tr ue) is not defined when dlg is a JPanel...Leave a comment:

JPanel like JDialog
Hello, in this code suppose that the dlg is defined in one case as a JDialog, I run it and it seems that the JDialog is executed AFTER closing it, so the message is printed after closing the JDialog.
But when I run the code with dlg defined as JPanel it prints the message before I close the JPanel.

I found a solution (I know it sucks! and it's 100000 miles away from JosAH's ) It consists of declaring the ResourceBundle variable also in the Conver panel (this is just an example panel to see how to change its labels) and in the init components method call the getBundle and the getSring in the setText of each label and button.
I think that this is working... could I try this one while find something better?

Yes, now I have the listener which is the Selector class I post here.
It works fine but there's a problem I can't solve:
I have a Menus class which is only a menu with 3 items: File,Help and Descriptive. when you select the File item there is the Configuration item where there is a combo box to select the language, when you select a language and click the button it changes the language of the File,Help and Descriptive items, that works...Leave a comment:

Change language of menu
Hi! I'm trying to let the end-user select the language of the menues I'm showing him.
To do that I've got this Selector class that shows the end user a combo box, a label and a button. In the combo box the user selects the language (English,Spanis h,French,..) and when he clicks in the button shows the label in the language selected.
This works fine but it's just one form, I need to change the language of all the menues in an application,...
