  • How to make the contents of NSTextField selected?

    Hi,
    I'm creating an NSTextField (from within a custom NSView):
    NSTextField *textField = [[NSTextField alloc] initWithFrame:NSMakeRect(20, 20, 50, 16)];
    [textField setStringValue:@"abc"];
    [textField setSelectable:YES];
    [textField setEditable:YES];
    [textField selectText:self];
    I want the contents to be selected ready for the user to start typing, but despite calling selectText, the text field is never selected. Is there another step I have to do first?
    Thanks
    Steve

    Now, if you change NSView to NSTextView in the @interface, you will see the behaviour I'm getting, that the NSTextField still appears and functions, but the contents are no longer selected.
    I haven't put this in a testbed yet, Steve, but need to ask a couple questions anyway: Are you (1) having a problem getting your NSTextField object(s) to accept first responder, or unable to select text manually? Or (2) are you expecting to see the selected text when a text field object isn't first responder (i.e. when it's neither displaying the caret nor connected to the field editor)?
    As to #1, your code shows that the text field is added as a subview of the NSTextView object. Have you tried making the text field a sibling view? I.e. both the text view and the text field would be subviews of the content view, but the text field(s) would be higher in the subview order. You can change the order by dragging in the xib window (with the View Mode switch in Center position), or you can send [addSubview:positioned:relativeTo:|http://developer.apple.com/mac/library/docum entation/Cocoa/Reference/ApplicationKit/Classes/NSViewClass/Reference/NSView.html#//appleref/occ/instm/NSView/addSubview:positioned:relativeTo:].
    If #2, I don't know of any easy way to get NSTextField to highlight text when it's not first responder. In fact I don't think NSTextField remembers which text was selected once it's no longer editing. From [Text Fields, Text Views, and the Field Editor|http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/UI TextView/TextFieldsAndViews.html#//apple_ref/doc/uid/20001799] in +Text Views+:
    Because only one of the text fields in a window can be active at a time, the system needs only one NSTextView instance per window to be the field editor. Among its other duties, the field editor maintains the selection. Therefore, a text field that's not being edited typically does not have a selection at all. (However, developers can substitute custom field editors, in which case there could be more than one field editor.)
    On the other hand, +NSTextView does remember+ the range of selected text and highlights that text in a different color when not editing. So you might consider creating additional smaller NSTextView objects in place of the NSTextField objects.
    The [Cocoa Text System|http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/Te xtArchitecture/TextArchitecture.html] is rich in [details and capabilities|http://developer.apple.com/mac/library/documentation/Cocoa/Concept ual/TextEditing/TextEditing.html#//apple_ref/doc/uid/10000157] about which I'm clueless. So if you need to dig much deeper, I hope one of our OS X experts will respond.

  • How to display the contents of java.util.list in a frame???

    i should use awt only not applet...

    the contents contains rows queried from a oracle database.....
    the contents should be displayed similar to how a lable is displayed..

    thanks

    Of course there is something in AWT:
    http://java.sun.com/j2se/1.5.0/docs/api/java/awt/List.
    htmlagain, if you carefully read the question, he needs a
    table to display a JDBC result set. There is no
    pre-made table component in AWT.Well, I read that he filled the data into a java.util.List and now wants to display this list. So a List-component should be sufficient. But I might be wrong...

  • How to print the contents of doubly-Linked List

    Hi
    I have a DLList consists of header , trailer and 10 linked nodes in between
    Is there a simple way to print the contents ie "the elements"
    of the list
    thanks

    In general you should write an iterator for every linked data structure for fast traversal. I'm guessing you're writing your own DLL for an assignment because one normally uses the LinkedList structure that is included in the api. Anyway, here is an example of how the iterator is implemented for a double linked list:

    Do you guys have any idea on this? Thank you very much for your replies

    For your listbox data to bind the listbox requires a Sequence. This is something that you can sort out at the entrypoint of your code.
    In the example below I have used an ArrayList to simmulate the data you have entering your FX code, but then I put that list into a Sequence, in your case instead of having an ArrayList in your FX code, you simple supply the list on entry, as I have marked in the following code.
    * Main.fx

    //Simmulate your data with an ArrayList
    var simpleList: ArrayList = new ArrayList;
    simpleList.add("Hello");
    simpleList.add("World");
    // *** This is what your entry point would become, just load the simpleList.toArray() into your sequence ***
    var simpleSequence = [];
    simpleSequence = simpleList.toArray();
    //after some time add some items, to show that our binding is working
    Timeline {
        repeatCount: 1
        keyFrames: [
            KeyFrame {
                time: 5s
                canSkip: true
                action: function () {
                    //you can work on the Sequence to add or remove
                    insert "Another item" into simpleSequence;
                    //if you at some point want to have your array reflect the changes
                    //then perform your changes on that too
                    simpleList.add("Another item");
                    //remember depending on your app
                    //you may keep the update of simpleList
                    //until you are finished with this view and do it in a single update
            KeyFrame {
                time: 10s
                action: function () {
                    //Alternatly, to keep your ArrayList correct at all times
                    //add items to it and then update your Sequence
                    simpleList.add("Added to array");
                    simpleSequence = simpleList.toArray();
    }.play();
    Stage {
        title: "Application title"

            height: 80
            content: [
                ListView {
                    items: bind simpleSequence
    }You can bind to a function rather than the data, which I am sure would be needed some cases, for example if the listBox data was a named part of a hash value for example, all that is required is that your function returns a sequence.

  • How to show the contents of a dropdown list with different colors

    Hi,
    I have a drop downlist on my dialog. I want to show each of its text attribute and its back ground with different color.
    Suppose I am showing 4 strings in the dropdown like Name1, Name2, Name3 and Name4, then how to change the color of each name and its background.
    Please let me know if it is possible.

    If the above asked is not possibe can we have an alternative as mentioned below :-
    A dropdown similar to the one shown in "Edit->Preferences->Grids->Colors" having our own text names instead of the default color names.
    So that I can show some color symbol and a text name along with it in my dropdown.
    One more query, is it possible to show the images/giff/png files in dropdown ?

  • WD ABAP: How to get the contents of selected table lines?

    Hi,
    I'm trying to figure out how to get the contents of table lines back from the UI. I display a table with several lines of data. The user selects some rows. I want to move the contents of the selected rows to another table. I have a context attribute, say DATA, with attributes FIELD1... FIELDn, using a DDIC structure. These are bound to the table UI element and the corresponding table columns. To get the selected rows, I use wd_context->get_selected_elements(). This works, but what I get from this method is references to if_wd_context_element. How do I know which row (row number = ?) this corresponds to? And how do I get the actual data? I want a structure with FIELD1 = value1 FIELD2 = value2 etc. My context attributes FIELD refer to table columns, but I'm looking for the table line...
    Can somebody help me?
    Thanks,
    Ira

    Hi Ira,
    wd_context->get_selected_elements() returns WDR_CONTEXT_ELEMENT_SET which is a table type of IF_WD_CONTEXT_ELEMENT. You can loop through the WDR_CONTEXT_ELEMENT_SET, get into variable say node_elelement which is of type ref to If_Wd_Context_Element. Then you could use the method GET_STATIC_ATTRIBUTES of If_Wd_Context_Element which returns a structure with values of all the attributes in the selected row.
    If you need the row number, while populating the node you could have an additional attribute called rowno and populate it correctly. When you select the data using method GET_STATIC_ATTRIBUTES, you would get the appropriate row number.

    Srini.

  • How to update the second JComboBox according selection in first JComboBox??

    I am having a hard time to update the second JcomboBox according to the selection of the first JcomboBox. For example, the content of the first JcomboBox is {city, rent}. When "city" is selected, the content of the second JcomboBox should be set to a number of cities. When "rent" is selected, the content of the second JcomboBox should be set to a range of rent.
    Since I have to detect the selection in actionperformed(), where the JcomboBoxes have been added to a Panel, and my JFrame setContentPane() to this Panel, I don't know how to update the JFrame or the Panel. I can make the old JFrame disappear and a new JFrame appear instead, but this is not what I want. I tried method update(Graphics) and removeAll(), and never made it work.
    I would greatly appreciate if anyone could give me any help.

    Thanks for your response. I fixed the problem in the following clumsy way:
    frame.getContentPane().remove(mainPanel);
    mainPanel.remove(box2);
    if(box1.compareTo("city")==0)
    box2 = new JComboBox(cities);
    else if(box1.compareTo("rent")==0)
         box2 = new JComboBox(rents);     
    else if(box1.compareTo("type")==0)
         box2 = new JComboBox(types);
    box2.setBounds(305, 30, 90, 20);
    mainPanel.add(box2);
    frame.getContentPane().add(mainPanel);
    Maybe there is a better way, but I don't know, and I don't understand your suggestion, could you further explain it? Thanks a lot.

  • How to compile the hint to force selection statement to use index

    Hello expert,
    will you please tell me how to compile the hint to force selection statement to use index?
    Many Thanks,

    Not sure what you mean by compile, but hint is enclosed in /*+ hint */. Index hint is INDEX(table_name,index_name). For example:

    No, your Yahoo account is not in iCloud (which only handles iCloud mail), it is in Yahoo, and the Yahoo mail account is on your iPad.
    But the MacBook Pro will have none of it! I write this question now as I fear that I will be totally demented very soon and unable to formulate my thoughts clearly!
    Get the correct settings for your account from Yahoo and set it up manually.
    By the way, I also find the "password" issue problematical. It seems Apple want my Apple password rather than my eMail password. All very confusing.
    That would depend on what you are trying to do.

  • My iPhone 5 has broken and is being replaced with a new iPhone tomorrow. However, My carrier (orange) will b picking up my broken iPhone and I am unsure how to secure the content and icloud data on the broken phone. Is there a way to display the data?

However, My carrier (orange) will b picking up my broken iPhone and I am unsure how to secure the content and icloud data on the broken phone. Is there a way to disable the data held on it and ensure that if it is fixed, nobody can use/see my data and access my account?

    Hi Gazpan,
    Thanks for visiting Apple Support Communities.
    I recommend using the steps in this article to back up your iPhone if possible:
    iOS: Back up and restore your iOS device with iCloud or iTunes

    You may also find this advice helpful for your situation:

    If you no longer have your iOS device
    If you're using iCloud and Find My iPhone on the device, you can erase the device remotely and remove it from your account by signing in to icloud.com/find, selecting the device, and clicking Erase. When the device has been erased, click Remove from Account.
    If you're unable to complete either of the above steps, you should change your Apple ID password. Changing your password won't remove any personal information that is cached on the device, but it will make sure that the new owner can't delete your information from iCloud.
    Cheers,
    Jeremy
