Update from the drop-down list on the duration

Hello, I'm fairly new to Java and Blackberry development.

I am doing an application with a few editable text fields and drop-down lists. What I want to do is to change the options from the drop-down list (ObjectChoiceField), according to what is written on the text fields, all without pressing a button. Can someone give me a hand here? I thought to use invalidateAll to redraw the field, but I'm not sure.

Thank you.

OK, something else, this looks bad for me:

your having

unitChoiceField.setChangeListener (editListener);

But editListener is not defined until after that, so with that statement, you're

the listener of null changes.

Put this line after you set your headset to changes.

Also we say something "does not work", is not very useful.  If please do some debugging and tell us what he does not she should do this, rather than saying that it does not work.  Imagine that you took your car be fixed and told them that it did not work.  Would they be able to fix it?

  • update of a drop-down list of QML from C++ fails the first time

    Hey gang,

    I have a function in my C++ class that seeks a couple of drop downs by ObjectName and their Options adds.

    the feature works well - except that when the application first starts, the function cannot find the menu drop-down, then the drop-down list is empty.  At various times during the execution of the application, it refreshes the drop-down list and those all great works.  It is only on the first attempt when the application first starts it fails.

    Here's the function:

    void WorkManager::updateDropDown() {
    //  qWarning() << "WorkManager::updateDropDown(), running..";
    /*
     * this function updates the two drop down lists in the UI
     * it updates them dynamically with the taskName() ('label') of the job.
     * NOTE: for some reason, this doesn't find the dropdown's by name on first start.  however subsequent runs work fine.
     */
        int i = 0;
        QList  myObjects = m_model->toListOfObjects();
        DropDown * dpList = bb::cascades::Application::instance()->scene()->findChild("scriptListDropDown");
        DropDown * logDpList = bb::cascades::Application::instance()->scene()->findChild("logDropDown");
        if (dpList != 0 && logDpList !=0 ) {
            dpList->removeAll();
            logDpList->removeAll();
            for (i = 0; i < myObjects.size(); i++) {
                Task * myTask = static_cast (myObjects[i]);
                myTask->setParent(this);
                dpList->add(Option::create().text(myTask->taskLabel()).value(myTask->command()));
                logDpList->add(Option::create().text(myTask->taskLabel()).value(myTask->taskName() + ".log"));
            }
        } else  {
    //      qWarning() << "WorkManager::updateDropDown(), ---> dpList was 0, try again";
        }
    }
    

    so when the application starts, I get this message of qWarning() and dpList (and logDpList) are both 0.

    I tried the dissemination of calls to this function in various places at the same time the C++ class, so in onCreationCompleted() different signals in the QML IU - as for the homepage, TabbedPane, drop-down menus.

    No matter where and when I call, I can't get the drop-down list to provide information on the first try.

    is there a way to find a way to make this work?  It's (quite) a little annoying.  I wish that the onCreationCompleted() for the drop-down list would work, but alas, no joy.

    Help?

    Thank you!

    Quite simply, if the object is not in the scene tree, you will get a result of findChild. It has not been created or added to the scene.

    You say that you did above in onCreationCompleted of a drop-down list, but this would only guarantee that one of your drop-down menus has been created and your conditional statement requires that both happening simultaneously be non-null. You must run the above, when the two objects are created.

    It seems that you can split the above function to manage separately, the dpList and logDpList after the onCreationCompleted of signals for each drop-down list.

    Note: If you run findChild on the user interface of your entire application, your application has a serious design flaw.

  • Raising the event "output" from a drop-down list in all instances of a table row

    I have a drop-down list in a row of table with multiple instances that performs a calculation on the exit event. This calculation takes information from 2 other drop-down lists listed above not repetitive rows of the same table.

    The behavior desired is: If the user change their choices above, all instances of the drop-down list below to execute the "Exit" event script to access the new values above.

    My script is:

    RowOptionalCoverage.DdlCoverageType.execEvent ("exit");     It works, sort of

    It updates only the first instance of RowOptionalCoverage and any subsequent instances. The user can 'Tab' through instances and trigger output for each instance event, but this isn't a reasonable solution.

    I tried using the method resolveNodes without success. I understand, using the method resolveNodes may be required when you reference multiple instances of an object:

    this.resolveNodes ("RowOptionalCoverage [*]. DdlCoverageType [*] ") .execEvent ("exit");"     does not work

    xfa.resolveNodes ("RowOptionalCoverage [*]. DdlCoverageType [*] ") .execEvent ("exit");"      does not work

    No doubt, I have to be incorrectly using the resolveNodes or rate something? Probably something simple.

    All the tips are greatly appreciated.

    Stephen

    Hello Stephen,

    You need to loop through each instance of the line and force the exit event. Without the form, it should look like:

    var oRows = xfa.resolveNodes ("RowOptionalCoverage [*]");
    oNodes var = oRows.length;
        
    for (var i = 0; i)< onodes;="">
    {
    xfa.resolveNode ("RowOptionalCoverage [" + i + "]"). DdlCoverageType.execEvent ("exit");
    }

    You could also index table to determine the number of row repeat:

    var oNodes = RowOptionalCoverage.instanceManager.count;

    You may change this to make it work.

    Good luck

  • Select from a drop-down list and the specified element values are displayed in the textfield

    I need for one to be able to select from a list drop-down and specified the item values appear in textfield.

    For example, if I select Amy

    If I select Bob

    If I select Jane

    Amy

    Bob

    Jane (I want to appear as shown in the list)

    I associated a value to each item in the drop-down list so that the choice is easy to compare and determine what initial (default) value to the value in the text field. In my drop down list change event, I have the following:

    var sNewSel = this.boundItem (xfa.event.newText);

    Switch (sNewSel)

    {

    case '1': / / Amy

    TextField1.rawValue = "Amy \n";

    break;

    Switch (sNewSel)

    {

    case '2': / / Bob

    TextField1.rawValue = "Bob \n";

    break;

    Of course that's not work one name shows at a time. Help, please!

    Thank you

    Don't know what the code is supposed to do, but basically, you want to add the name of the drop-down list the addition on the current value of the TextField? Why not use the dropdownlist display value directly? For example on the change event:

    if ( TextField1.rawValue == null )
        TextField1.rawValue = xfa.event.newText;
    else
        TextField1.rawValue += ( "\n" + xfa.event.newText );
    
  • Help select the value from a drop-down list box

    Hello

    I develop a script (in JavaScript) which will allow a user to select an export PDF presets (that are loaded in a drop-down list) and then export the InDesign file to PDF, by using the selected PDF preset.

    I have the combo fill properly and I am also able to export to PDF correctly, however I have a problem setting the preset has been selected by the user. Here are some of my code fragments:

    Drop-down list:

    with(borderPanels.add()) {

         pdfDD = dropdowns.add();

         sl = new Array();

         for (i = 0; i < app.pdfExportPresets.length; i++)

         sl.push(app.pdfExportPresets[i].name);

         pdfDD.stringList = sl;
         pdfDD.selectedIndex = 0;

    }

     

    ...

     

    myPreset = pdfDD.selectedIndex;

    In PDF format:

        // Open, Export, & Close
        for (i = myFileAmount; i >= 0; i--) {
            app.open(File(myFolderContents[i]));

            createHyperlinks();

            app.activeDocument.exportFile(
            ExportFormat.pdfType, File(myFolder.fsName + "/" + app.activeDocument.name.split(".indd")[0] + ".pdf"), false, myPreset);
            app.activeDocument.close(SaveOptions.no);
        }

    During the passage of myPreset, it is defined as 6 (the index from the drop-down list).  How can I set myPreset that the real value of what has been chosen?

    Thank you!

    In view of your code, you probably need something like:

    myPreset = app.pdfExportPresets.itemByName (pdfDD.stringList [pdfDD.selectedIndex]);

  • Add options from a drop-down list of c ++

    In my C++ files, I have a QMap to data that I want to add a drop-down menu that I have in QML.

    I can't find examples of how to add options to a menu already existing but.  Here's what I have in my file QML right now:

    DropDown {
                        id: account
                        title : "Account"
                        enabled : true
                    }
    

    It seems it should be a fairly easy process to get the id of the drop-down list and enter the data of my inside QMap.

    Any help with this would be greatly appreciated!

    Oh, I didn't see that you do not know how to connect the logic of C++ to the UI QML, the ID of the component QML is not enough, you must set objectName: property 'dropDown' too.

    You can reach any CPP QML object like this:

    This excerpt comes from YourProjectName.cpp
    create the active document of the main.qml scene
    Set parent document created to ensure that there is overall
    application lifetime

    QmlDocument * qml = QmlDocument::create("asset:///main.qml").parent(this);

    Create the root for the UI object
    AbstractPane * root = qml->() createRootObject;
    game created the root like a scene object
    App-> setScene (root);

    and here's the findChild method
    Drop-down list * dpList = root-> findChild ("combo");

    After this line, dpList will point to the controller of the user interface.

  • How to change or remove a line from a drop down list?

    I have a spreadsheet Numbers drop down box that shows the 3 lines of the text when I start typing the text in the cell. I have to enter the same text 3 times during the construction of the document. How can I remove 2 of these lines of text?

    Hi Brudduh,

    Click the cell that contains the context menu,

    Click on the brush to Format to open the Format Inspector and click cell.

    The Inspector displays the menu items in the context Menu in this cell.

    • To remove a menu item: click on the item to select. Click the button below the list.
    • To edit an item: double-click on the item to select content. Modify if needed.
    • To add an item: click on the button +. Type the content of the element.

    To use the same drop-down list in a different cell:

    • Click the cell that contains the menu to select. Copy.
    • Select the cells to the same menu. Dough.

    Kind regards

  • Filling of a numeric field by selecting from a drop-down list

    Hello all;

    I went through the 38 pages on the form now to try to understand it myself. I must have missed something or this day becomes medium long.

    I am filling a numeric field that is based on what is selected in a drop-down list box.

    For the test, I use only 2 fields

    DropDownList1 and digital Field1

    I If (DropDownList1.rawValue == 1) { }

    NumericField1.rawValue = 25;

    }

    On the other;

    (DropDownList1.rawValue == 2) { }

    NumericField1.rawValue = 35;

    }

    That worked. I am now getting the error "missing; before the statement

    "6:xfa: form1 [0]: #subform [0]: DropDownList [0]: output"

    Specify the value of points is checked in the tab links for DropDownList1.

    I said this with a single selection, who worked

    if (DropDownList1.rawValue == 1) { }

    NumericField1.rawValue = 25;

    }

    Thank you all

    Chomp

    If it's a copy/paste of your script, you have a semicolon after the "else" and "else" should be lowercase.

    And for nested IFS, you need an "else if", so:

    If (DropDownList1.rawValue == 1) {}

    NumericField1.rawValue = 25;

    }

    Else if (DropDownList1.rawValue == 2) {}

    NumericField1.rawValue = 35;

    }

    ElseIf...

    If you have a lot of statements, you might want to look at using a statement that may be easier to read.

    {Switch (DropDownList1.RawValue)}

    case '1 ':

    NumericField1.rawValue = 25;

    break;

    case '2 ':

    NumericField1.rawValue = 35;

    break;

    etc.

  • Slide to pause until that value is selected from a drop down list?

    Hi there everyone.

    I try to create a cover page of sorts for a simulation of system where the user is asked to enter his name and choose where they work in for a combo box (using the drop-down list box widget)

    I have the name entry part work and the drop-down list box is displayed, but I'm having some problems with it.

    First of all, as soon as a value is selected in the box is jumps to the next slide. I would have rather navigation controlled by a button that the user can make sure that they have chosen the correct value before continuing. Is there a way to do this?

    Hello

    This is the craziest question, but think I found the reason: Although the widget looks a lot smaller in edit mode, when opening it (preview or published) it falls above the button. When I have it away, seems to work. Can you confirm?

  • Add/Remove the same exact point from a drop down list

    Hello!

    I need power remove/hide and/add/view THE SAME POINT, or that it doesn't look like the same question, please see the example of what I m doing:

    When you open the document:

    01.png

    If you click 'Yes' to the first radio 4 value is added

    02.png

    If you click 'Yes' in the second radio, value 5 is added

    03.png

    If you click 'no' on the first radio, you remove the value 4 BECAUSE you remove the element #3

    04.png

    If you click on 'no' on the second radio, you delete nothing 4 BECAUSE you try to delete the point #4


    05.png

    And then you get this weird combination

    06.png

    This is the code on the first Radio

     form1.#subform[0].value_4::click - (JavaScript, client)

    if (this.rawValue == "1") {
         DropDownList1.addItem("value 4");
    }else {
        DropDownList1.deleteItem(3);
    }

    This is the code on the second radio

    (this.rawValue == "1") {
           DropDownList1.addItem("value 5");
    }else {
           DropDownList1.deleteItem(4);
    }

    Anyone know how to remove a specific item of a dropdrown? or may not remove, hide only if this is possible... I tried to change specific values for Add/Remove always from the same point, but it did not work.

    Thank you!

    Ago, I find it odd that there is no native method xfa for the index of an item in the menu drop-down. Not documented at least (as I know).

    What you can do however, is create your own method!

    Here, in the initialize event of your highest subform you create a method that exends class object (which includes all XFA objects too), like native JavaScript:

    //@para String value of the item in the drop down
    //@return Boolean - true if item was deleted, false if not and null object if not found in the list
    
     Object.prototype.deleteItemValue=function(sVal){
     for (var a=0;a
    

    You can remove any item from your drop by modying your code:

    if (this.rawValue == "1") {
     DropDownList1.addItem("value 4");
    }
      else {
     DropDownList1.deleteItemValue("value 4");
    }

    If you open these in LC Designer, you can view the script by selecting the menu drop down and looking at the script at the top of the window Editor. If the script editor is a single line, you can drag the lower edge to make it bigger.

  • The Back button only allows me to return a page at a time instead of select a previous page from a drop-down list. It is a real problem: someone has any ideas?

    In the previous version of Firefox, I could go back to a previous page by clicking on a part of the previous button which brought up a list of recently visited sites and clicking on one of them, might go back to this page. This installation does not seem to be available in the latest Firefox, and the back button only goes back one page at a time. It's really embarrassing, like,

      it now takes longer to get to an earlier page
      there is no visibility of previous pages visited
      any actions carried out on webpages are undone when going back through them - this does not happen when jumping back several pages in one go.
    

    It is a real problem, I used the old system constantly and cannot continue to use Firefox 4.0 unless there is a way around it.

    Use it to open the history list:

    • Right-click on the back or next button
    • Press and hold the left button of the mouse on the active back or forward button until the list opens

    What you describe is the way documented in what forms Acrobat and Acrobat JS behave by Form Event Processing

    For your described form, we can use a custom format for the field drop-down list script:

    If (event.willCommit! = true & event.changeEx! = "")
    {
    var devused = this.getField ("device");
    var proname = this.getField ("product name");
    Envoy of var = this.getField ("sent to the sponsor");
    Switch (Event.changeEx)
    {
    case "related product": complaint
    devused. Required = true;
    proname. Required = true;
    smells. Required = true;
    break; Go at the end of the switch;
    Repeat fdor each value of the option in the drop-down list.
    by default:
    If no match for the above cases, it is found;
    devused. Required = false;
    proname. Required = false;
    smells. Required = false;
    break;
    } / / end of switch event.changeEx;
    } / / end not true willCommit;

    You must set the ' Commit selected value immediately "and as one moves upwards or downwards the options, the related fields will change and stay together when you exit the field note that the field name is not used in the script because the field is the event object until it leaves the field.
