?? Why "MenuItem (String, int, int)" deprecated in 1.3?

This was annoys me but didn't really think to post so far, in the 1.3 version of the SDK, MenuItem (String, int, int) is marked as obsolete, but there is no other manufacturer for it, then why is it marked obsolete without another manufacturer? So basically in the "Problems" section, I have 'Problems' on all THE MenuItems as warnings for being obsolete, but I've got NO solution for it because there is no other visible manufacturer?

In addition, in the "javadoc" for MenuItem, that's what it shows

[QUOTE]

net.rim.device.api.ui.MenuItem

Represents an abstract menu item.

Each element has an ordinal by specifying the sort order in the menu. A separator is automatically inserted between adjacent elements whose ordinals differ at least 0x00010000. Each item has a priority by specifying that one should be the default value. A lower value indicates a higher priority.

Creating items menu with commands

Since BlackBerry 6.0 API, you can use command framework API to create a menu item. The procedure is the following:

  1. Set the features to make using a CommandHandler. The order manager can be limited to your application, or can be registered is available to any application on the BlackBerry smartphone.
  2. On your screen, optionally specify the context of the menu item by calling setCommandContext(). The context may be required to determine what should be the command handler.
  3. Associate the menu item to a command by calling setCommand(). The command defines what to run when the menu item is selected by acting as a proxy to an instance of a class that extends a command handler. The command is executed only if there is no implementation of practicable. If the context is specified, it is passed to the command executes the method. Otherwise, this menu item is passed.

Code example

 class MyUiScreen extends MainScreen
 {
     public MyUiScreen()
     {
       //...
       // Create MenuItem with command context
       MenuItem myItem = new MenuItem("My Menu Item", 110, 10);
       myItem.setCommandContext(new Object()
       {
           public String toString()
           {
               return "My MenuItem Object";
           }
       });
       // Set command to be invoked by the MenuItem
       myItem.setCommand(new Command(new DialogCommandHandler()));

       addMenuItem(myItem);
     }

 // A CommandHandler implementation which will be executed unconditionally
 class DialogCommandHandler extends CommandHandler
 {
     public void execute(ReadOnlyCommandMetadata metadata, Object context)
     {
         Dialog.alert("Executing command for " + context.toString());
     }
 }

Creating menu items by subclassing and by implementing Runnable

If subclassing the extension class must implement the Runnable interface that supports in turn Expedition summary of actions from the menu during activation.

    ...
    // setup the menu items
    MenuItem item = new MyMenuItem();
    menu.addItem(item);
    ...
    class MyMenuItem extends MenuItem {
        MyMenuItem() {
            super(MyResourceBundle.getBundle(), MyResource.MY_MENU_ITEM, 0, 100);
        }
        public void run() {
            // do something
        }
    }

StringProvider: "Provides a string that can be changed. The most common use would be for locale changes. "If you hard-code the channels then it is useless, if you use a resource bundle then it is great because you simply provide the family resource and ID to the creation and the rest is handled internally.

  • Why substitution strings are now old value in application translated even after seed/publish?

    Hello

    Recently, I noticed a small, but from the perspective of our customer "big" issue. We defined in our application, some chains of substitution to keep more detailed information about the version of the application. Later, they are used in page templates to display information to end users. Recently I had to update the value of one of the chains of substitution. The change is immediately visible in the main application. Unfortunately, it is not the case for the translated application. For some reason the old value is retained. Even after doing the "seed"-> "Apply translation file"-> "publish." It is keeping the old value. I tried to use the "Translatable" checkbox in the model. In the translation file, is to show correctly the substitution in the 'source' and the tags string 'target', but still he is resolved to the old value.

    We use the APEX 4.2.2.00.11 running on 11g.

    Waiting for suggestions that maybe it's me forget somewhere extra time "checkbox. Thank you in advance.

    Greetings,

    kempiak

    It was my mistake. Value of the substitution string is included in the translation file. I changed it it and it works perfectly.

  • An array of strings as function parameter in loop fails

    Hallo,

    I have a weird problem here and I hope someone can help me find the cause.

    I have a function where I said an array of strings (string_list). I pass the array to a function that does modifactions to the table. I am addressing Walker the array of strings to an index of all the values are stored correctly. When I loop through the array by incrementing the index automatically only the last index value are saved in all positions.

    Why is this? Or what I am doing wrong?

    It is the passage to another function, an array of strings
    int calling_function
    {
    char * string_list [MAX_PATHNAME_LEN]; //< store="" strings="" in="">
    function_called (string_list); passing a pointer to an array of string
    return 0;
    }

    This is the function receives a reference to an array of strings to store data
    int function_called (char * output_list [])
    {
    int i = 0; counter variable
    / * This works and good values are stored in output_list * /.
    output_list [0] = '02 ";
    output_list [1] = '12 ';
    output_list [2] = "22";
    output_list [3] = "32";
    output_list [4] = '42 ';
    output_list [5] = "52";
    output_list [6] = '622 ';
    output_list [7] = "72".

    / * This does not work and will store '31' in all places of the matrix * /.
    < 32="">
    {
    < %d »,="" i) ;="" incrémenter="" la="" valeur="">< br=""> output_list [i] = sample; < br=""> i = i ++ ; < br=""> < br="" >="">

    output_list [0] = '02 "; < br=""> output_list [1] = '12 ';< br="" >="">

    Thanks!

    Hi,.

    When you do

    output_list [i] = sample;

    all of the members of the array have the same value: sample-a char pointer. You are modifying the afterwards glad of sample purpose the previous values still point to sample.

    If you assign values to each array member like:

    you assign different values: a pointer to a string containing "02", pointing to a string contaning "12",...

    If you want to assign values in a loop you need to allocate memory for each string (output_list [i]) and copy the content of sample in them.

    Does this make sense to you?

  • Features of LabView string StartsWith as in c#?

    Hi all

    I want to create a switch/case (structure-case) block in labview for this code:

    This can be done already with the structure of the case, you can make simple analysis in the case selector, which takes a string as input.

    Type in the case of the first case "XYZ".... "XYZ".

    Enter the next case "DEF".... "DEF ~".

    Next is the empty string, the default value.

    How does this work:

    The "XYZ...". "XYZ ~ ' matches all strings that begin with XYZ and any ascii value after the ~ is the highest value printable 7-bit ascii for that catches all the other characters.

    Option 2 is parse (there is expression reg very good vi in the channel palette) the string and create if a corresponding to the value of the integer can habdle unique integers in the structure of the case.

    There are so many ways to do it without a wrapper for the string .net class, I have provided some quick methods

  • How to find the size of the text string...

    Hi friends,

    How to find the size of the text, in KB or in bytes or MB, I have a text box control, when I type a text in do I find the size of the text that is entered control.please of entry help very urgent...

    Thnaks

    Balu-

    Hi David,

    Nice Solution, but I think that it will not give the exact size of the string for a particular case where the string contains UTF string as a single letter format can exceed more than 1 byte.

    So I think it should be modified as:

    private function getTextSize(value:String): String

    {

    var div_by:int = 100;

    var sze_is:String = 'KB ';

    var len_is:int = getUTFLength (value); now the length is actually measured, regardless of the format of the text

    If (len_is > 1000000)

    {

    div_by = 100000;

    sze_is = 'mb ';

    }

    Return(string(math.round(len_is/div_by)/10)+sze_is);

    }

    private void getUTFLength(value:String):int
    {
    var byteArray:ByteArray = new ByteArray();
    byteArray.writeUTFBytes (value);
    Return CharArray.Length;
    }

  • String Concat does not work

    Hi all!

    I have the following code:
                    if (roundedWorstCompressFactor < 0.75 || roundedAvgCompressFactor < 0.75 || roundedBestCompressFactor < 0.75) {
                        String impossibleCFs = "";
                        if (roundedWorstCompressFactor < 0.75) impossibleCFs.concat("Worst Case");
                        if (roundedAvgCompressFactor < 0.75) impossibleCFs.concat(" Average Case");
                        if (roundedBestCompressFactor < 0.75) impossibleCFs.concat(" Worst Case");
    
                        jLabel23.setText("It isn't possible to achieve " +  impossibleCFs + " CFs");
                    }
    When I debugged my code, I realized that even inside if statements evaluates to true, the concat method makes no difference. Text of a jLabel resulting becomes so "is not possible to obtain the CFs. Why the String class concat method does not work?

    When you apply the function concat on string, it does not alter the original string, it returns a new string with the desired result. Therefore, assing the value returned to your variable. So, try this:

       impossibleCFs = impossibleCFs.concat("Worst Case");
    

    As an alternative, also review the StringBuffer data type. It has the function append() you can use without affecting the result to the original variable. Once you're done, you can use StringBuffer.toString () to get the final string.

    Thank you!

    you call

    but you do not add this menu, you?

  • Problem get the handle to the module using CodeModuleGroup

    I need to get the object moduleHandle of some modules that I don't know the name of the runtime so I use CodeModuleGroupManager.loadAll () then a loop in the list of the modules that it returns.
    From there I need to obtain the handles of some modules based on information module, but it does not work.
    By using the following code I get 0 or a number that appears to be no valid for a moduleHandle object.
    I use this api incorrectly? I tried to get the handle based on the name and friendlyName properties. This maybe isn't the way to do it, but I couldn't figure a way deparaments.
    Thus, using the information returned by the loadAll() method, I would like to know the right way to get the Handle to the module.
    Any help is appreciated. Thank you.

    modules = CodeModuleGroupManager.loadAll ();

    for (i = 0; i numModules; i ++) {}

    String fname = modules [i] .getFriendlyName ();
    String name = modules [i] .getName ();

    / * 3 following below almost always return 0. Why? */
    moduleHandle int = CodeModuleManager.getModuleHandle (fname);
    moduleHandle = CodeModuleManager.getModuleHandle (name);
    handle = int [i] modules .getHandle ();
    }

    CodeModuleGroupManager.loadAll returns a returns an array of CodeModuleGroups, not CodeModules.  You try to use the name of a CodeModuleGroup to get the handle of a CodeModule.

    If you want the CodeModule handle, call first getModules() on your variable modules and the loop through this enumeration.  If you want that the handle of the CodeModuleGroup call getHandle on your variable modules.
