Click button to see the Dialog.Alert

Hello, I'm new to the development of Blackberry and I can't get a SIMPLE dialogue. Alert show on click of a button.  Talk about programming most frustrating I've ever done.  If someone could help me please I would appreciate it a lot!

ButtonField btnCalc = new ButtonField ("Calculate", ButtonField.FIELD_LEFT |) ButtonField.CONSUME_CLICK);
btnCalc.setPadding (0, 0, 0, 4);

FieldChangeListener customListener = new FieldChangeListener() {}
' Public Sub fieldChanged (field field, int context) {}
Dialog.Alert ("Hello");

}
};

btnCalc.setChangeListener (customListener);

Hello

class pk extends MainScreen
{
pk()
{

    ButtonField btnCalc = new ButtonField("Calculate", ButtonField.FIELD_LEFT | ButtonField.CONSUME_CLICK);
    btnCalc.setPadding(0, 0, 0, 4);

    FieldChangeListener customListener = new FieldChangeListener() {
    public void fieldChanged(Field field, int context) {
    Dialog.alert("Hello Pawan");
    }
    };

    btnCalc.setChangeListener(customListener);
     add(btnCalc);
}
}

Its fine workying. I test. When you click the button, you will get Dialog.alert.

Thank you
Pawan

    };
    

    and I have problem of course that shows me all name lines generated only modified (for example name03).

    can you help me please?

    Thank you

    Stepan

    (1) change

    btnSearch = new ButtonField ("Search");

    TO

    btnSearch = new ButtonField ("Search", ButtonField.CONSUME_CLICK);

    (2) I would have thought that you want something like

    protected boolean trackwheelClick (int status, int time)
    {
    ListRander selectedLine = (ListRander0 (this.getSekectedIndex ()) info.elementAt;

    String name = selectedLine.getName ();

    Dialog.Alert ("Selected:" + name);
    Return super.trackwheelClick (status, time);
    }

  • Use a button to the reversal, or click here to see the hidden text

    I am using Captivate 8 and I want to use a custom button I created as a rollover or click to view the object.

    For example, I have a useful suggestion I want the user to see if they choose to click on a light bulb.

    The bulb is customized to three positions (high, low).

    There is NO option to have this button to act as a trigger to display a text like a rolling caption.

    I thought it was a fairly common feature - I can't do that in Captivate?

    If I use the function of turning over I got to fix above my button. Although rolling works, he defeated the Visual purpose to have the button to display a different color turnover, since the bearing must be on a top layer.

    Is there a custom code that I can use for this?

    Check out this blog:buttons on Question/Score 6 Captivate Slides?-Captivate blog

    Although the question slides, there a button configured to display information. But you need a tip or, since you're on CP8, joint action.

    I'm a little surprised when you say "There is NO option to have this button to act as a trigger to display a text like a rolling caption."? The success of your button action has a long dropdown menu with simple actions possible, one of them is show. You're supposed to hide this legend of text (or shape with text) and make it visible with the Show command. If you want to toggle the button to act like a button, you'll need a user variables and a conditional advanced or shared action. Something like this:

    IF v_visib equals 0

    See the Tx_n

    Toggle v_visib

    ON THE OTHER

    Hide Tx_n

    Toggle v_visib

    v_visib is a user variable, a Boolean value that has two possible rated: 0 means that the object is invisible, 1 that it is visible. I would prefer a shared action here, with only Tx_n (the legend of text) as a parameter. You can override this setting by any object or group, when you use an instance of this action. It is one of the actions in my shared library of actions.

  • Redirect when press button ok on the dialog box

    Why do you need to access the OK button of the alert? Just do what you want to do after the display of the dialog box - the statement after Dialog.alert will be reached only after the user presses the OK button (in general). If you want to detect if the user rejected the dialogue this or any other way, create your own one, doModal on it and analyze the returned result:

    Dialog myWarning = new Dialog(Dialog.D_OK, "Unable to send results, check connection, please try again", Dialog.OK, Bitmap.getPredefinedBitmap(Bitmap.EXCLAMATION), 0L);
    if (myWarning.doModal() == Dialog.OK) {
      // OK button was pressed - do what you need here

  • eBay pages now show button to see the full description

    As of today, something on Ebay has changed in coding that affects only Firefox, 35.0.1. OSX

    Before today all the descriptions of items and photos were shown normally, suddenly there is now a «see the description of the complete article»

    button, this ONLY displays to me in firefox, if I view any pages on Ebay with any other browser- Safari, Chrome etc the pages all display correctly.
    

    Ad block I disabled and tested with her at sea, no difference, Ditto for the cookie blocker, on or off makes no difference.

    See the pictures of the screen:

    1. 1 a screenshot of a page in Safari Ebay
    2. 2 an identical snip of the same page using firefox

    Update on this issue:

    All of a sudden, from today, that the problem has disappeared, now each page on Ebay shows the correct way, as he did before.
    I have not installed, updated or changed something in the browser.
    The button "See the description of the complete article" disappeared and a complete description and images all appear by default as they did before.

    Better that I can understand is Ebay had changed the FF code choked on it, and after complaints enough they came with a fix on Ebay for the problem posed their scripts.

  • Right click on the "back" button to see the history? You got to be a joke.

    Every day, it's something new...
    Why the hell see you correspond to remove the arrow on the buttons ' back/forward' that has allowed to look through several pages of previous or next drop VERY PRACTICE? Yes, I am well aware, that you can now achieve through a right-click on the button, but come on, that's just stupid. Nothing of that at all intuitive.
    Stop the deletion of these options. You may want to it a certain way, but that's great for you and you alone. We give users the ability to keep these settings very simple and ridiculous way we want that they.

    You can also hold down the left button of the mouse on the active back or forward button until the list opens.

  • WVC210 missing controll buttons in «See the video»

    Hello!

    It sems miss me buttons zoom and snapshots in the page "see video" for my camera. I saw pictures and videos of others using the same model, and they have more options above the buttons to pan and tilt. I tried different settings and also tried with IE and Firefox on different PC but always with the same result. I noticed that there is a difference when you use FF instead of IE. With FF, there are missing pieces in the installation program for the detection of movement. Control of sensitivity and are missing. No doubt som activeX plugin missig or something, but it's the same on three different PCs: I've tried so far.

    My browser settings?

    Example: http://docs.google.com/Doc?id=dhbzwrnw_0df5qh4cp

    Hello!

    Thank you for you answer. I will try your suggestions later in the evening. I am running Vista on most machines, but also tried on XP with no luck. I've been tinkering with different settings for ActiveX and Java (like Dotnet) in IE and FF but nothing has worked.

    (P & T works but the zoom buttons, snapshot, PT with 'point and drag' and output video choise is missing on the page)

    Last night, I downloaded IE 8.0 well and eventually got it to work!

    Don't know why but at least I saw the features that I wanted and that you can continue to set up my camera and concern to fix the rest later. It's amazing how something so simple as a camera can take as long to implement. (Fun to learn something new so :-))

    Next step is to receive alerts by workstation (my ISP requests SSL with no exceptions). As I wrote in a different thread, I won't use any PC on the network with the camera. Just a 3G router and a modem. What makes my limited options as to find a workaround for mail.

    Thanks again!

  • Button to see the passwords stored in Firefox browser?

  • Single user lock screen requires now click here to see the password field; what setting or API controls this?

    At first, this may seem like only an issue with a third-party application, but the question applies to Windows in general. I am a software developer and experienced Windows user, but I can't seem to find no answer on what's going on.

    Normally lock on Windows 7 Professional 64-bit (when you press Windows + L for example) display an icon of great user, the user name, the word "locked" and a password field and a "Change user" button. But after installing the client VPN Junos Pulse , my lock screen changes: it is a tiny user icon and no password field. I have to click the tiny user icon before a password field is displayed:

    This situation is not limited to the Junos Pulse. I found the people ask this question after installing programs face connection. Others have had the same problem. And still others have had this problem - more recently. But no one can provide no answer to which change the login screen.

    If I uninstall Junos Pulse login screen returns to normal. But the question is not about Junos Pulse; I want to know what Windows setting or API call causes this situation. What could be the Junos Pulse that would lead even this behavior?

    Yes, I already checked that there is only one user account after the installation of Junos Pulse, and the guest account is disabled.

    Junos Pulse setting changed to change the behavior of my lock screen, and how to make a lock screen normal return that immediately presents the password field without requiring an additional click?

  • How can I get my Close, minimize and maximize buttons to see the

    When I first installed Photoshop CS6 extended on my Mac it had a bar along the top that had the name of the program in it (Photoshop) with red, orange and green, close, minimize, and maximize buttons in it.

    Somehow I have this turned off and the three buttons no longer appear. Here is a photo of the bar example, I am eager to start:Screen shot 2012-06-08 at 5.52.16 PM.png

    I have the frame of the application running, and they do not always show. I am of course the simple answers, but any help would be much appreciated.

    AHA! I solved the problem! (Using one of the older posts of station_two actually). The solution was to trash the preferences file, and here's how I did it:

    1 closed Photoshop

    2. open Photoshop holding command + Option + shift (Mac OS). Then, click Yes to the message, "Delete the Adobe Photoshop settings file?"

    And everything has been reset to normal. Admitidly I had to recreate my workspace, but it was a small price to pay.

    Thanks Station_two.

  • Creation of Play button to see the Animation

    Hello.

    I made a button by creating a new symbol naming and defining it as a button. Then I edited the four frameworks for my taste. Then I added it to a layer on my calendar by dragging the library.

    I looked at other tutorials on youtube and others, but all code etc. doesn't seem to work. I'm using Flash CS5.

    Once I created the button, what do I do to make him stop the animation at the beginning and play when it is pressed.

    Thank you

    ~ Joe

    in the first image of your main timeline add your button in the properties panel, assign an instance name (for example, btn) and use:

    Stop();

    btn.addEventListener (MouseEvent.CLICK, f);

    function f(e:Event):void {}

    Play();

  • See the dialog box under Bill of lading

    Run the following code

    commentaireset var = commentsPageDef.createObject)

    commentsPage.open)

    processingMessage = "Loading comments"

    processingDialog.open)

    The processingDialog shows but under the sheet. If anyone has experienced this before?

    Solution is to call the load signal, not the signal of onCreationCompletion() onOpened() dialog box.

    I'm going to explain why to anyone who runs into the same problem in the future. Because the sheet is not identical to a page, it is pushed on top of everything. If you press a page on top an existing page using the NavigationPane, sheet can be pushed on top of that.

    The only competitor of a leaf is a dialog box. Since all the components are technically completed being created before growing the leaf, pushing a dialogue on the signal of creationCompleted sheet will push the existing dialogue before THEN push the sheet above it.

    Using the signal of onOpened(), you can always push the box on top of the sheet once the leaf is 'open' - animation is complete.

    I hope this helps.

  • How to make a text click button appear on the screen

    I have a map of the United States and each State has a bearing which changes the color of the State... what I'm trying to understand is to click on the State and have the text appear on the side of the U.S. card and keep this text until the user clicks on another State. Any help will be greatly appreciated. Thank you

    The way I've been suggesting is to manually add the TextField to step through the tool in the tools bar, not not using code to create (even if you can).  I think that coding is new to you that you will do best to start with small doses.  The textfield object that you add manually will be delivered with all the settings you want in the properties panel.
