How to make a JComboBox undoable

Hi all,
I'd like to do a JComboBox undoable i.e :
Having an initial list of items for this combo box...
a) Extend JComboBox by UndoableJComboBox implementing StateEditable
b) implement methods storeState and restoreState
c) Add actionListener for this undoable combo box
d) Add to Combo InputMap ctrl-z (undo) and ctrl-y (redo)
When selecting consecutively different items for this combo, being able to retrieve the former selected values by undoing with ctrl-Z.
Thanks for your advice
Laurent

I tried the function showPopUp() and as well as setPopUpVisible(). But as you indicated the JComboBox must be showing for it to work.
What I was looking for is a part in the code where I can intervene so that the popup will be drawn as well every time the JComboBox is drawn on the screen. I wanted to avoid to call showPopUp at every location where the status from the JComboBox could change from showing to not showing.

How to make editable JComboBox uppercase

Can some one tell me how to convert user entry in to a editble JComboBox to Uppercase?.
Thanks.

Here is some initial code as an example to do what you want. You will see the inital problem with it when you start typing some characters into the JComboBox. Maybee you will figure it out before I do but this is a great challenge. I figure if there is some way to override java placing the character into the box then this would work with little modification.

    comboBox.setEditable( true );
    main.setLayout( new FlowLayout() );
    main.add( comboBox );

    mainWin.show();

How to make jcombobox display all by itlself?

Hello all -
Is there a way to make a jcombobox object display its column of items implicitly?
For example, suppose a program has a combobox filled up with names. And, suppose the first item says "toggle sort", which affects how the items are sorted in the combobox (eg, pressing it should cause the list to sort the displayed names based on first name, another press bases the sort on the last name...). The behavior I am aiming for is that when the user presses the "toggle sort" item, the combobox displays its items again awaiting further selection from the user (but not the first item). Know how to fire such an event?
private void namesComboBoxActionPerformed(ActionEvent evt) {
   int selected = namesComboBox.getSelectedIndex();
   if (selected == 0) {
      // some code should result in the namesComboBox displaying its items again. What is it please?
}

Here is a simple code, I don't know if its the correct way to do this sort of thing but it works:
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.util.ArrayList;
import java.util.Collections;
import javax.swing.*;

How to make the swing drawings to appear in a specific jPanel?

hi,
I have a frame which I divided in two panels - one for the jComboBoxes/buttons and the other one for showing graphics. but the paint(Graphics g) overpaints it all =(
how should my code look like if I want some rectangles (depending on the combo choices and on button click which means update) to appear in the second panel?
the code's structure is like :
import *;
public class NewJFrame extends javax.swing.JFrame {
     private JPanel jPanel1;
public static void main(String[] args) {
          NewJFrame inst = new NewJFrame();
          inst.setVisible(true);
     public NewJFrame() {
          super();
          initGUI();
     public void paint(Graphics g) {
          g.fillRect (x, y, w, z)
     private void initGUI() {
          jPanel1 = new JPanel();
               // combo boxes and buttons
               // action listeners for them
          jPanel2 = new JPanel();
               // the place where the rectangles should be shown
               // and updated if combos are changed and button clicked
}now, I wonder if anyone could possibly give me a hint how to make it correctly, because I'm really a total newb in Java and I can't find any good examples from www which I've search through for the solution.
P.S. is there a plug-in for eclipse for visual programming of the graphics? =)
thank You for the kindest help!
J.M.

You should not be mixing AWT and Swing component in
a Swing application, so don't use a Canvas.
If you need some custom painting then you should
override the paintComponent() method of JComponent or
JPanel and then add this component to the GUIwhat does mean the override the paintComponent() method of JComponent or JPanel?
how can I add that component to the GUI?
=)
can you give a short code example, please! the code structure would be more than enough.

I was able copy the hardrive of my old macbook from "My Passport" onto the desktop on an older iMac. but i dont know how to make my hardrive and user name be the main one since someone had used it in the past and had their info on the comp. please help!

I recently broke my 2008 macbook. i was able to use an external hardrive to back up my data onto My Passport. I was going to buy a new computer but a friend told me sher had an older version of the iMac. (not sure how old but it doesnt have a camera if that helps) i was able to hook it up and turn it on but i ran into a few problems. 1) the "authentic" user or whatever it says is someone who previously used the computer. i added me as a user but im not sure how to make me the main user. 2) after hooking up My Passport, i was able to drag my files and copy them to the desktop.(i think i did it correctly) now, i dont know how to make my hard drive and applications and iformation the "main " info. The current apps on the iMac are super old versions of iTunes and iPhoto and such. 3) while trying to open the apps from my macbook on the iMac, it said it didnt have the right software to open these apps.
I am so computer illiterate so someone please help!!! Also, i do not have internet in my new apartment yet so if there is a way to make this happen without using the internet that would be preferred. sorry for the horrible spelling and poorly written paragraph.
THANK YOU!!

You are not going to be able to run your old system from the backup on this old computer as the hardware is incompatible.
You need to get a new computer or a refurbished one.

else if (MessageBox.Show("Do you want to save changes to AssignedDialyzer.pdf before closing?", "DRRS", MessageBoxButtons.YesNoCancel, MessageBoxIcon.Exclamation) == DialogResult.No)
this.Close();
The above code executes well with no problem at all!
As you can see the file to which i create and save and open my pdf report is
AssignedDialyzer.pdf.
The column headers of table in pdf report from c# windows forms using iTextSharp are
"Reprocessing Date","Patient Name","Dialyzer(Manufacturer,Size)","No.of Reuse","Verification" and
"DialyzerID".
However the problem i am facing is after execution and opening of document is my
column headers in table in pdf report from
c# and datas in it all appear in bold.
I have browsed through net regarding to solve this problem but with no success.
What i want is my pdf report from c# should be similar to following format which i was able to accomplish in vb6,adodb with MS access using iTextSharp.:
Given below is report which i have achieved from vb6,adodb with MS access using iTextSharp
I know that there has to be another way to solve my problem.I have browsed many articles in net regarding exporting sql datas to above format but with no success!
Is there is any another way to solve to my problem on exporting sql datas from c# windows forms using iTextSharp to above format given in the picture/image above?!
If so Then Can anyone tell me what modifications must i do in my c# code given above so that my pdf report from c# windows forms using iTextSharp will look similar to image/picture(pdf report) which i was able to accomplish from
vb6,adodb with ms access using iTextSharp?
I have approached Sound Forge.Net for help but with no success.
I hope anyone/someone truly understands what i am trying to ask!
I know i have to do lot of modifications in my c# code to achieve this level of perfection but i dont know how to do it.
Can anyone help me please! Any help/guidance in solving this problem would be greatly appreciated.
I hope i get a reply in terms of solving this problem.

How to make downloadable links in Adobe Muse

I am new to website design and am trying to figure out how to make downloadable links for some PDF flyers, PSD templates I am creating. Not sure if "downloadable links" is the correct term for what I'm trying to say but in a nutshell I am creating Business Flyer's in PDF form and Photoshop PSD template files that I would like to be able to have my users click a link that allows them to download them right to their desktop. Any help would really be appreciated!

I cannot figure out how to make the text larger on an incoming email. The finger method doesn't work and I cannot find any toolbar with which to do it. I could find nothing in settings also. Plese help and thank you.

I cannot figure out how to make the text larger in a received email. The finger method doesn't work and I can find no tool bar as I can for composing emails. I can find nothing in settings. Please help and thank you in advance.

Hi there,
Download a piece of software called TinkerTool - that might just solve your problem. I have used it myself to change the system fonts on my iMac. It is software and not an app.
Good wishes,

How to make a JPanel selectable

When extending a JPanel and overriding the paintComponent() method the custom JPanel can not be selected so that it gets for example KeyEvents.
But if I make the new Class extend a JButton it gets of course selected and able to receive for example KeyEvents.

Hello Anybody, I have a question. Can any of you please suggest me how to make an xml file from the database table with all the records?

The Oracle documentation has a good overview of the options available

How to make an icon image using Photoshop

I found out how to do this recently so I decided that I wanted to make a tut for those who don't know how to make an icon image. This icon image is for the libraries tab on your computer. Under the libararies tab there is Music, Pictures, Documents, and Photos
First you will need the ICO (Icon image format) Format extension for photoshop which can be downloaded here:
http://www.telegraphics.com.au/svn/icoformat/trunk/dist/README.html
The download link and tutorial on how to install it is all in the link above.
Once you have that all set you can now launch photoshop to create your icon image. Once you have launched it, create a new document with the size as in the image below.
[IMG]http://i1297.photobucket.com/albums/ag25/dusty951512/256x256_zpsbf3dcf8e.png~original[/IMG]
Create the image you want. I used a simple one by using the custom shape tool by pressing "U" on your keyboard and with the
basic blending options.
[IMG]http://i1297.photobucket.com/albums/ag25/dusty951512/IconImage_zpsd788c709.png~original[/IMG]
The reason why the image is pixelated is because it is an icon image. Since the image is only 256x256 pixels when you zoom in on it that will get you the pixely result. The reason why I zoomed in is so you can see it. But don't worry this is no the end result. Just continue reading and you will see.
So once you have created the icon go ahead and press
file>save as>(under format choose the ICO)>and choose the name that you want to name it. And save it in your C: drive. You will see why to save it in your C: drive in a sec.
[IMG]http://i1297.photobucket.com/albums/ag25/dusty951512/SampleicoPic_zpsd252bfba.png~original[/IMG]
So now that you have created the icon and saved it now you can create the new library.
[IMG]http://i1297.photobucket.com/albums/ag25/dusty951512/NewLibrary_zps8ca703b2.png~original[/IMG]
Name the library whatever you want I named it "Sample" for tutorial purposes. Notice how it gives you a default boring icon image for your library.
[IMG]http://i1297.photobucket.com/albums/ag25/dusty951512/Sample1_zpsb5472840.png~original[/IMG]
So now once you have created and named your library now it is time to get the icon image into place.
Go to computer/c: Drive/users/YOU/ And now once you have reached this area you will need to access a hidden folder named "appdata" to do so press "Alt" then a menu bar will show. Click
tools>folder options>and view. Find the option to view hidden folders then press apply then ok. Now we shall continue so AppData>Roaming>Microsoft>Windows>Libraries
Now you should see all the libraries including the one you just created.
[IMG]http://i1297.photobucket.com/albums/ag25/dusty951512/showhiddenfolder_zpsad4a3c94.png~orig inal[/IMG]
[IMG]http://i1297.photobucket.com/albums/ag25/dusty951512/Libraries_zpsf6243bc0.png~original[/IMG]
Once you have reached your destination then open a new text document with notepad and drag the library you just created in notepad. The result should look like this:
[IMG]http://i1297.photobucket.com/albums/ag25/dusty951512/Notepad_zps251a86f0.png~original[/IMG]
once you have reached this point click at the end of the second to last line down then press enter and enter in this information
<iconReference>c:\"NAME OF ICO FILE YOU CREATED IN PS".ico</iconReference>
Example:

Once you have entered that information go to file>save and the icon image should appear on the library you created.

It is Windows only because all those screen shots are exclusively Windows, the file structure and paths do not resemble those of the Mac in the least. As a Mac user, there's nothing I could take from your tutorial. Sorry,
No drives named with letters like C: on the Mac, for instance. No backward slashes either, ever. No such paths either. No "Notepad" on the Mac, we use TextEdit; but such a text editor is not remotely needed on the Mac to make and/or edit icons. Etc.
Those folders are not even called "Libraries" on the Mac… Nothing resembling your tutorial at all.
The icons in the Finder's Sidebar are not customizable at all in recent version of OS X.

How to make text start at the top of a page in livecycle 9

Hi, How can I get the text in a large text field to start at the top left of the field rather than at the center of the field? In addition, may one know how to make text wrap in the form as well?
Thanks,
David

To set the Text alignment properties use "Paragraph" pallet you can make it visible by selecting Window>>Paragraph or Shift+F5
And to allow text wrapping you need to select "Allow Multiple Lines" checkbox under "Object" pallet and "Field" tab. You can make Object pallet visible by selecting Window>>Object or Shift+F7.
Good Luck,
