Can anyone help me in join the 3 combo boxes with filters
The main idea is there are 3 combo boxes
when we select an item in the first combo box the related items should apper on the remaining 3 combo boxes
and when we select an item on the second combo box then the related item should appear on the last(third) combo box.
Do anyone has an idea please help me
Thanks,
What code do you have so far for your problem?
I am using the code as follows
At first I am displaying the List of items in the 3 comboboxes and then implementing the actionlisteners for 2 comboboxes inorder to load list of items at runtime the code is as follows
first I am usng actiolistener for the APPSET combobox inorder to get the selected items in the remainig 2 combo boxes the code is as follows and it is woring perfectly
// creating AppSet Label
private JLabel getAppSetLabel() {
if (this.appSetLabel == null) {
this.appSetLabel = new JLabel("App Set:");
}
return this.appSetLabel;
}
//Getting data into APPSet Combo Box
private JComboBox getAppSetComboBox() {
if (this.appSetComboBox == null) {
this.appSetComboBox = new JComboBox();
// Populate the App Set list
this.appSetComboBox.addItem("All Application");
ArrayList<String> anAppSetList = CBRCPMDailyT20AppManager.instance()
.getAppSetList();
for (int i = 0; i < anAppSetList.size(); i++) {
this.appSetComboBox.addItem(anAppSetList.get(i));
}
this.appSetComboBox.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent eventset) {
appSetComboBox_actionPerformed(eventset);
}
});
}
return this.appSetComboBox;
}
//Implementing the action listener
private void appSetComboBox_actionPerformed(ActionEvent eventset) {
String appSet = this.getAppSetComboBox().getSelectedItem().toString();
//String appSet = "AMADEUS_ABG";
this.appSetComboBox.setSelectedItem(appSet);
this.getAppComboBox().removeAllItems();
this.getPackageComboBox().removeAllItems();
this.appComboBox.addItem("All Application");
this.packageComboBox.addItem("All Application");
ArrayList<String> anAppList CBRCPMDailyT20AppManager.instance()
.getAppList(appSet);//replace by appSet
for (int i = 0; i < anAppList.size(); i++) {
this.appComboBox.addItem(anAppList.get(i));
}
ArrayList<String> anPackageList CBRCPMDailyT20AppManager.instance()
.getPackageList(appSet);//replace by appSet
for (int l = 0; l < anPackageList.size(); l++) {
this.packageComboBox.addItem(anPackageList.get(l));
}
this.appComboBox.setSelectedIndex(0);
this.packageComboBox.setSelectedIndex(0);
}here I am removing all the items from the 2 combo boxes list before I adding the items at runtime so it is giving me the Null Pointer Exception error when I am adding the action Listener to the second combo box(APP) in order to display the related selected items in the third combo box(Package) at runtime by selecting an item in the APP combo box
When I comment this statement
this.getAppComboBox().removeAllItems();the action lisener of APP combo box is working nd I am getting the data in Package combo box.
But the problem is the list of items are displaying many times because I am loading the App combo box for 2 times
for firs time normally
and second with actionlistener of AppSet at runtime
This is my problem, I think I had explained clearly,
Please give me an Idea to solve this
I will be very much thankful to you
Could you make a small program that compiles and executes and demonstrates the problem?
Exactly which line is giving the NPE? Is it in getAppComboBox() - where's that code?
It seems you did not understand the my problem
I will explain now clearly again in three points
1. I am adding 3 combo boxes to the toolbarpanel their names are APPSET, APP, PACKAGE.
and I am dispalying the List of items for all the combo boxes as normally .
2. I am adding action listener to the APPSET combo box and by this actionPerformed method I am at first removing the items from the 2 combo boxes(APP, PACKAGE) and adding the items at runtime.
Up to this my code is perfect there is no problem
3.Now I want to add another action listener to APP combo box and should add the items to the PACKAGE combo box again at runtime.
But when I add an action listener to the APP combo box it is giving Null Pointer Exception because I am removing All the items from Both the Combo boxes at Action Performed in APPSET
So this is the problem
can you please give any idea
Thanks
I understood what you said, so there was no need to say it again. I'm not stupid. But if you don't want to give me the additional info I asked for, that's OK. Good luck. I'm outta here. Bye bye. J
their names are APPSET, APP, PACKAGE
Are you sure you have posted the correct code. There are NO varibles with the names: APPSET, APP, PACKAGE in your code???
I am sorry,
It is not like that , don't think so
I gave answer for the first reply and not for the second one
I am giving the code now
The problem is exactly with the RemoveAll statement that I had placed in the APPSET ActionPerformed method
So is there any idea for placing this ReplaceAll command in another way inorder to delete the items form the APP combobox and not in the ActionPerformed method
Please help me I will be very thankful to you
private void appSetComboBox_actionPerformed(ActionEvent eventset) {
String appSet = this.getAppSetComboBox().getSelectedItem().toString();
//String appSet = "AMADEUS_ABG";
this.appSetComboBox.setSelectedItem(appSet);
this.getAppComboBox().removeAllItems();
I am getting errir here can I place this anywhere but not here
Please suggest me an idea
this.getPackageComboBox().removeAllItems();
this.appComboBox.addItem("All Application");
this.packageComboBox.addItem("All Package");
ArrayList<String> anAppList = CBRCPMDailyT20AppManager.instance()
.getAppList(appSet);//replace by appSet
for (int i = 0; i < anAppList.size(); i++) {
this.appComboBox.addItem(anAppList.get(i));
}
ArrayList<String> anPackageList = CBRCPMDailyT20AppManager.instance()
.getPackageList(appSet);//replace by appSet
for (int l = 0; l < anPackageList.size(); l++) {
this.packageComboBox.addItem(anPackageList.get(l));
}
this.appComboBox.setSelectedIndex(0);
this.packageComboBox.setSelectedIndex(0);
}Thanks
Yes I had posted the correct code which is exactly working in my Eclipse
please suggest me an idea
Thank you very much
I think the problem is that your IDE has changed the names of the variables. There is no variable named: APP in what you posted.
It is important when posting code to use the same name as the variable in the program when talking about the code. Otherwise there is confusion.
Hello NormR1,
Thanks for your reply
Now again I am posting the code
the combo boxes are app, appSet, package

this.getAppComboBox().removeAllItems();But when I remove this I am not getting the error
but my data in the app combobox are repeating many times
Please help me in this,
Thank you very much.
What does getAppComboBox() return? Why not use appSetComboBox?
Hello JamesCherrill,
getAppComboBox() will give the list of items for the app combo box
the getAppComboBox() code is as follows
public JComboBox getAppComboBox() {
if (this.appComboBox == null) {
this.appComboBox = new JComboBox();
// Populate the App list
this.appComboBox.addItem("All Application");
ArrayList<String> anAppList = CBRCPMDailyT20AppManager.instance()
.getAppList();
for (int j = 0; j < anAppList .size(); j++) {
this.appComboBox.addItem(anAppList .get(j));
}
// this.appSetComboBox.removeActionListener(appSetComboBox);
this.appComboBox.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent eventset) {
appComboBox_actionPerformed(eventset);
}
});
}
return this.appComboBox;
}and I don,t understand your question where to place appSetcombobox()
can you give me an idea
Thank you very much
getAppComboBox() will give the list of items for the app combo box
So why is it declared as returning a JComboBox?
Exactly what error are yo getting now?
Hello JamesCherrill,
I am getting the following error because I am using the
this.getAppComboBox.removeAllItems();in the appSet_actionPerformed() method
If I won't use this then the data in the app combo box are repeating many times whenever I select an item in the appSet combo box

I used return appComboBox just to return the valus to the app Combo
Thanks in advance
The syntax you just quoted isn't right right, so its not very helpful.
Exactly which line of code does the error refer to - it has the line number but I don't have a current listing to match that up with.
Are you saying that you create a new JComboBox just so you can use it to return some values?
JamesCherrill,
Yes I am creating 3 JComboboxes and returning values to them
The error just refer to the following line
this.getAppCombobox.removeAllItems();Which is in the appSet_actioPerformed() method
It is as follws
private void appSetComboBox_actionPerformed(ActionEvent eventset) {
String appSet = this.getAppSetComboBox().getSelectedItem().toString();
//String appSet = "AMADEUS_ABG";
this.appSetComboBox.setSelectedItem(appSet);
this.getAppComboBox().removeAllItems(); this.getPackageComboBox().removeAllItems();
this.appComboBox.addItem("All Application");
this.packageComboBox.addItem("All Package");
ArrayList<String> anAppList = CBRCPMDailyT20AppManager.instance()
.getAppList(appSet);//replace by appSet
for (int i = 0; i < anAppList.size(); i++) {
this.appComboBox.addItem(anAppList.get(i));
}
ArrayList<String> anPackageList = CBRCPMDailyT20AppManager.instance()
.getPackageList(appSet);//replace by appSet
for (int l = 0; l < anPackageList.size(); l++) {
this.packageComboBox.addItem(anPackageList.get(l));
}
}The Line I quoted in red
I am getting error for that line
But If I remove it I am not getting the error but the data is repeating for the selections in the appCombobox
Thank you very much
One last time before I move on to something else...
why are using getAppComboBox() instead of just referring to appComboBox like you do on the next line? It can't be what you told me earlier - "give the list of items for the app combo box" - because the very next thing you do is to remove all the contents anyway.
Hello JamesCherrill
Ya becuase For the first time I
should display all the List of items for the 3 comboboxes
Depending on the combo boxes I am displaying a table
and If the user just want to see the table that filters on the appcombobox
without or before the actionlisteners in the appSet so it is used
And if you have any idea to change the without displaying the app and package comboboxes for the first time and implement the actionlisteners for the app and appSet comboboxes
Please tell me and give tha code according my code
Then I will manage here
I will be very much thankful to you for spending a lot of time on my isuue
Thanks a lot
Create the combo boxes at initialisation time (ie by calling the get method, just once only), but don't put any data in them. Then in the action handler just check if the existing combo box is empty and, if not, removeAllItems(), then load the new data into it.
HelloJamesCherrill,
If you don't mind can you please give me a piece of code
for this how to implement
I will be very greatful to you and sorry for wasting your valuable time
Thanks
Sorry, forum rules say I can help you by suggesting good directions to go in, and helping to fix specific problems, but I can't write your homework code for you.
Just slow down, step back a bit, look at your overall code, then dive into particular parts.
If you're using Eclipse the use the code folding feature to hide all the implementations of your methods so all you see are the signatures, then think about exactly what should be done in each one, and what data each one needs to do that.
Hello JamesCherrill,
Thank you very much
But Please give me an idea for how to implement an actionlistener for appComboBox inorder
to get the data for package at runtime
Please suggest this idea
And moreover I am using Eclipse
Thank you very much
Please give me an idea for how to implement an actionlistener for appComboBox inorder
to get the data for package at runtime
This is very confusing. You already have an action listener for appComboBox, which contains code that apparently gets the data for package at runtime
ArrayList<String> anAppList = CBRCPMDailyT20AppManager.instance()
.getAppList(appSet);//replace by appSet
for (int i = 0; i < anAppList.size(); i++) {
this.appComboBox.addItem(anAppList.get(i));
}I thought your problem was that when you cleared the old data from the list you got an NPE, and you haven't responded to my questions or suggestions about that.
JamesCherrill,
The main problem is with the actionlistener in the getAppComboBox()
but not with the actionlistener in the getAppSetComboBox
and the code which you had pointed out is not for filling Packagecombobox but for filling the appComboBox based on the selection made in the appSetCombobox
Thanks
Yes, but it should be exactly the same structure except for the details of the CBRCPMDailyT20AppManager query, which I have no info for.

Thank you very much for spending your valuable time.
OK, so theres a
ArrayList<String> getPackageList(String appSet)
method just like the
ArrayList<String> getAppList(String appSet)
method that gives you the packages in a specified appSet, so, as I said, the new listener is exactly like the one you already have except that is goes from appSet to package, not from app to appSet
Hello JamesCherrill Sir
It is going for both for the first time
from appSet ---> app and appSet-->package
The first seletion is working perfectly, there is no problem in that
the problem is with the second selection should be from app--> package
So here is the problem withe the second listener,
Thank you very much
