GUI button question

hey,
i have been surfin the class library web site for a
while now and cannot figure out how to make it so
that my gui window closes when i push a button(a
JButton in a JFrame), can anyone show me how?
-MMWould it not be better to use the X(real close button) on the top right of the screen to close the app. If you want to do that then use this code-
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);replace frame with whatever you called your JFrame.

Gui Buttons don't press when upgrading from 1.1.8 to 1.4.0

We are upgrading an application from 1.1.8 to 1.4.0 and the Gui button's do not work. I believe it is due to some sort of focus problem (and parent windows) but cannot get it to break in a simple test application. Just wondering if anyone else has had gui problems when upgrading to 1.4.0. If I recompile back to 1.1.8 it works great.
Thanks.

wow that's odd...almost sounds like you have a transparent window that is over the buttons so it intercepts the mouse events. Would have to see some code but it really sounds like it's the code and not the jvm....if it were, I would think alot of people would be screaming.

How to change the Callback function of a GUI button?

I would like to change the callback function associated with a GUI button dynamically in the programming way.
Here is the code piece I tried, but it does not seem to work:
const char* pstrLabelSaveJpeg = "SaveJpegCb";
SetCtrlAttribute(pahel_id, ctrl_id ,ATTR_LABEL_TEXT, pstrLabelSaveJpeg);
int CVICALLBACK SaveJpegCb(int panel, int control, int event, void *callbackData, int eventData1, int eventData2);
Solved!
Go to Solution.

The attribute you used is about the "label" of the button.
It is just an appearence attribute. You can write your own name on it, but that does not change the callback function.
You should change the ATTR_CALLBACK_FUNCTION_POINTER attribute, and you should not pass the function name as a string.
So your function call will look like this:
SetCtrlAttribute(pahel_id, ctrl_id, ATTR_CALLBACK_FUNCTION_POINTER, SaveJpegCb);
Of course, you have to declare the SaveJpegCb function somewhere above that line.
I think you have already done that.

New GUI Buttons

Hi,
Besides the existing GUI buttons in Labview, are there any place where new GUIs can be created or downloaded?
Thanks alot
From
Don

You can easily make your own using the control editor, e.g. cut& paste buttons from any existing windows program (e.g. MS Office) using a screen capture utility and an image editor.
Also have a look at the openG button controls (see attached image). You can download and install it via the OpenG Commander.Message Edited by altenbach on 03-04-2005 08:31 PM

Updateable Report : re-display collection & Update Button question

This a sequel to a previous Updateable Report question I had.
Varad pointed me to this doc which has been incredibly helpful .
http://www.oracle.com/technology/products/database/application_express/
howtos/tabular_form.html#RESTRICTIONS
I was\am having the following issue :
Let's zoom to the part where we create a region to display the tabular form for the previously saved collection , and drill down to the part where we create an UPDATE EMP button for that displayed collection :
I was not able to display the collection again when I failed the validation a 2nd time. ie, clicking on the UPDATE EMP button after it displays both the errors-post validation and after displaying the collection ( of course) would return me to the previous report pre-collection creation. When I turned debug on I found out that it was not even creating the collection and was hence deleting it before displaying the subsequent page.
So what I did differently from what the documention instructs is as follows :
I removed the page reference on the 'branch to page' of the UPDATE EMP button. In my case, the default 'Branch to ' Page after Processing is the same page I am using for this part of the application.
So when I remove the reference to the page number. for that button, the page is then able to re-create the collection and hence re-display the collection so I can re-fix the 2nd error ( ... and 3rd) and finally update the report .
Just wondering if anyone else has had the same experience ?
Thanks !

The columns and rows have a set format for the Id, so if you know one Id you know the row and the ids of all the other columns.
As an example, this will show the value of column 6 when you click on any column with the function call in the Element Attributes:
Script:
<script type="text/javascript">
function showCol6(col){
var col6 = document.getElementById("f06_" + col.id.substr(4,4));
alert(col6.value);
</script>Element Attributes:
onclick=showCol6(this);You could also use a Named Column template, specific to this region, to include the column values directly in the function call, but I think it's best to stick with the ApEx defaults if possible.

} I need to make my next and previous button keep going through the array. They go next or previous one time and stop. I know it is because of the way I wrote the statement

C:\Inventory\Inventory.java:92: local variable i is accessed from within inner class; needs to be declared final
textArea.setText(myPart[i]+1+"\n");
^
C:\Inventory\Inventory.java:92: operator + cannot be applied to part,int
textArea.setText(myPart[i]+1+"\n");
^
2 errors
So I tried to write {nextItem()}
and writing a method for next item,
nextBtn.addActionListener(new ActionListener()
public void actionPerformed(ActionEvent ae)
nextItem();
}); // end nextBtn
lastBtn.addActionListener(new ActionListener()
public void actionPerformed(ActionEvent ae)
textArea.setText(myPart[3]+"n");
} // end lastBtn actionEvent
}); // end lastBtn actionListener
} // end main
private static void nextItem();
if (myPart < myPart[]-1)
     myPart++;
     textArea.setText(myPart[0]);
}and I get this error
C:\Inventory\Inventory.java:109: '.class' expected
if (myPart < myPart[]-1){
^
1 error
I thought '.class' expected meant I was missing a bracket, but I can't see where I am missing a bracket.
I feel dumber by the minute.
Am I not seeing something?

Another suggestion. First create a non-GUI Inventory class, something like this:
public class Inventory
    private part[] myPart;
    private int index = 0;
    public Inventory()
        myPart = new part[4];
        myPart[0] = new part("Glass Break", 730, 12, 32.19);
        myPart[1] = new part("Motion", 995, 14, 37.69);
        myPart[2] = new part("Keypad", 220, 12, 50.69);
        myPart[3] = new part("Contact", 944, 44, 1.19);
    public part getPart(int i)
        //TODO fill this in
    public part getFirst()
        //TODO fill this in
    public part getLast()
        //TODO fill this in
    public part getNext()
        //TODO fill this in
    public part getPrev()
        //TODO fill this in
    public double getTotalInventory()
        //TODO fill this in
    // this main is here only to test out the class
    public static void main(String[] args)
        Inventory inv = new Inventory();
        for (int i = 0; i < 4; i++)
            System.out.println(inv.getPart(i));
            System.out.println();
        System.out.println("getFirst: " + inv.getFirst());
        System.out.println();
        for (int j = 0; j < 6; j++) // deliberately set to be > 4
            System.out.println("getNext: " + inv.getNext());
            System.out.println();
        for (int j = 0; j < 6; j++)
            System.out.println("getPrev: " + inv.getPrev());
            System.out.println();
        System.out.println("getLast: " + inv.getLast());
}Then use this class as a variable within another class, say InventoryGUI. In this second class, the "next" button would call the Inventory object's getNext() method.

GUI Development Question

Hi everybody!
I'm quite new in ALBPM and I have some questions about it, especially about user interfaces.
I've been developing JSP aplications (using MVC frameworks) for a long time, and I can't figure out how does it fit in the ALBPM world.
What's the paradigm for GUI development? At first, I believe the screenflow should act like the controler, the BPM object is the model, and the custom JSPs are the views.
But... sincerely for me, the Screenflow/BPM object/Custom JSPs seem less flexible than a regular MVC (Struts, JSF, ...)
My question is: Is it mandatory to use screenflows, or I'm able to use a MVC architecture inside ALBPM? If it's possible how should I implement it?
For example: I have a custom JSP with some menu items, and this items are links to other JSP pages. This behaviour should
be modeled using screenflows or can I use another approach? What's the best practice for this task?
In MVC architecture, the menu will be inside an html form with an action pointing to a servlet (a controller). And what about screenflows?
Well, I'd like to hear some opinions about this, especially because i'm triyng to get used to BPM paradigm, and in my opinion the best approach for this is hearing from people who had experienced this situation.
Thanks in advance

The reason for this is due to our JVM. This application is being developed for an embedded system. There are no swing components in this JVM environment for a couple reasons: size constraints and possible license issues.

Good old "Disable brower's Back button" question.

I don't have to implement it. I am posing this question just out of curosity . Is there a way we can somehow disable Back button on our browser starting second page onwards?
I recently browsed one site that had "Next" and Previous" buttons on each page. Surprisingly Back button on all the pages was disabled.
I know, when we open the first page for browsing, Back button is disabled by default. Is there a way we can force browser to treat each and every page as the first page? How did they implement this functionality?
Thanks.

If you're using JSPs, simply ensure that they are not being cached by the browser.
<%
response.setHeader("Cache-Control","no-cache");
response.setHeader("Pragma","no-cache");
response.setDateHeader ("Expires", 0);
%>Otherwise, there are a couple of ways to do this via Javascript.

Disable gui buttons while excuting script

hi,
i have class that that calls script in one of methods
    synchronized(this){
         Process p = Runtime.getRuntime().exec("cmd /c start " + script.getCanonicalPath());
         p.waitFor();
    }I'm writting a swing gui above this class..
This method is quite time consuming, so i use swingworker for this(code above is called from doInBackground() method)
While i'm calling method above i would like to have buttons on my form disabled,
so i used this code:
      okButton.setEnabled(false);
      cancelButton.setEnabled(false);
      InitSwingWorker sw = new InitSwingWorker();
      sw.execute();As swing worker finisher buttons are supposed to be enabled again, so i enable them in the done() method of swing worker
public void done(){
            okButton.setEnabled(true);
            cancelButton.setEnabled(true);
        }And my problem is this:
buttons disables (that's fine), but they don't stay disabled until executing of script is done. They are enabled right away, i can see that they were disabled for few milis maybe,
but that's it.
thanks for any help with this :)

When you run a "start" command in the command processor it starts a background Windows process and returns immediately. It will probably work if you remove the "start".

Please help with the GUI quiz question!

Hi Folks,
Please help me with the code for the following GUI.
The display window of the application should have two panels at the top level (you could have multiple panels contained within a top-level panel). The first top level panel should have a grid or a border layout and should include apart from various label objects: 1) a textfield to store the info entered, 2) a combobox 3) a combobox or a list box , 4) a radio-button group , 5) a combo box 6) checkboxes for additional accessories, and 7) checkboxes .
The second top-level panel that is placed at the bottom of the window should have a submit button, a clear button and a textarea for output.
Thanks a lot.

Please be a little more explicit about what you're doing, what you expect to happen, and what you actually observe.
Please post a short, concise, executable example of what you're trying to do. This does not have to be the actual code you are using. Write a small example that demonstrates your intent, and only that. Wrap the code in a class and give it a main method that runs it - if we can just copy and paste the code into a text file, compile it and run it without any changes, then we can be sure that we haven't made incorrect assumptions about how you are using it.
Post your code between [code] and [/code] tags. Cut and paste the code, rather than re-typing it (re-typing often introduces subtle errors that make your problem difficult to troubleshoot). Please preview your post when posting code.
Please assume that we only have the core API. We have no idea what SomeCustomClass is, and neither does our collective compiler.
If you have an error message, post the exact, complete error along with a full stack trace, if possible. Make sure you're not swallowing any Exceptions.
Help us help you solve your problem.

GUI/Formatting question

I have a page where I want to display an image at the top, a scrollable panel in the middle, and a button at the bottom. I get all of these components, but they are all inside of the scroll panel and I don't understand why.
Here is the code:
<f:view>
        <html lang="en-US" xml:lang="en-US">
            <head>

                <meta content="no-cache" http-equiv="Pragma"/>
                <title>DisplayDiagnosis Title</title>
                <link href="resources/stylesheet.css" rel="stylesheet" type="text/css"/>
            </head>
            <body style="-rave-layout: grid">
                <h:form binding="#{DisplayDiagnosis.form1}" id="form1">
                    <h:panelGrid binding="#{DisplayDiagnosis.centeringGridPanel}" columns="1" id="centeringGridPanel">

                            <div style="height: 250px; width: 400px; overflow: auto">
                            </div>
                        </h:panelGrid>
                        <h:panelGroup binding="#{DisplayDiagnosis.groupPanel1}" id="groupPanel1" style="height: 50px; width: 100px">
                            <h:commandButton binding="#{DisplayDiagnosis.button1}" id="button1" onclick="history.back(); return false" value="Back"/>

                </h:form>
            </body>
        </html>
    </f:view>How should this look in order to get the image above the scroll panel and the button below it?
Note that I tried surrounding the DiagnosisPanel (the only one I want to scroll) with the div tag, but that didn't do what I expected.
In short, how do I get the DiagnosisPanel to be the only thing that scrolls?
Thanks.

Well that didn't come out too well (the code tag didn't seem to work right).
Here is my question posted on another site (JavaRanch) where everthing can be read correctly:

GUI class question

Hi guys I use the NetBeans 6.0 and i build a project which has 2 Source packages on is my number game and the other I called GUI. In the GUI source package I drew a diagram which I want to use as my GUI to my number game but I don't know how to connect them. Now my question is this is it possible to connect them since they are in different packages? And my second queston is where should I code the action listenrs and where the event handler couse I am really new to gUI and that is my first one. Btw does net beans 6 provide some form of facility to join them both without much code? Thanks in advance!

1.I would say that using packages in this case is bad, but i wont since everyone else here thinks its always good. I would just use plain .java/.class files in the same directory so that they have free access to each other and the other files.
2. To use actions listener you first make your main class implement ActionListener, then addActionListener(this) to all your components that catch events, then use public void actionPerformed(ActionEvent e) to handle any events.
