How to make the default tree row selection programatically

I have one use case where I am displaying the tree table based on some parameter which is just for filtering the table and display the part of hierarchy.
The problem here is I want to make a default selected row when the tree will be rendered to UI based on the primary key(that is the input parameter).
can you please tell me how to do this.I am using jdev 11g.
thanks,
Harsh

Hi,
for this you need to know where in the path the PK is. If e.g. the PK is for a second level node then you need to pass the first level node PK as well. Nodes in a tree are defined as ArrayLists. So unfortunately your question doesn't provide enough information

    Could anybody please enlighten me on how to make the APEX tree in the "Expand All" shape by default please? I created an APEX tree and by default it's in the "Collapse All" shape. I am using APEX 4.1.0.00.21

    Hi,
    you can check the view source of html and check the onclick code written on that plus sign(Expand All), just copy that onclick javascript code and put it on page javascript event.

  • How to make the obligate field in selection screen

    Hi ,
    In my report two radio buttons and two bloc selection screens are there.When we select the first radio button first screen will be editable second screen will be non-editable vice-versa.
    but the problem is in each selection screen one mandatory field is required  suppose if i give the one field obligatory in first block screen it is not allowing the second readout please help me regarding this how i will make the mandatory field in both screens.
    Thanks,
    Harinath

    Hi...
    Dont Declare your field as OBLIGATORY.
    Instead perform the validation in AT SELECTION-SCREEN event. But validation should be only when Particular Radiobutton is selected.
    And Generate only Error Message (Type E).
    Try this code:
    AT SELECTION-SCREEN on <yOUR mandatory field>.
       IF PA_UPD = 'X'.
             IF <YOUR MANDATORY FIELD>  IS INITIAL.
                  Message 'Entry is must in this field' type 'E'.
             ENDIF.
       ENDIF.
    AT SELECTION-SCREEN OUTPUT.
    IF pa_udp = 'X'.
    LOOP AT SCREEN.
    IF screen-group1 = 'ABC'. "#CCE
    screen-active = 1.
    ELSEIF screen-group1 = 'DEF'.
    screen-input = 0.
    ENDIF.
    MODIFY SCREEN.
    ENDLOOP.
    ELSEIF pa_rep = 'X'.
    LOOP AT SCREEN.
    IF screen-group1 = 'ABC'. "#CCE
    screen-input = 0.
    ELSEIF screen-group1 = 'DEF'.
    screen-active = 1.

  • How to make a Jtable's row selected thru program

    Hi , in my application few of the rows (not continous)
    need to get selected automatically when the jTable is intially shown.
    I did this using table.setRowSelectionInterval(0,2)
    This method works fine selecting all the rows from 0 th to 2 th row,
    but if i want only 0 th and 2 th ( excluding the 1 st row ) to be selected , i dont know how to do that???
    i tried the following also
    //indeces of rows to be selected in the table are stored
    //in array
    int[] array = new int [2];
    parray [0]= 0;
    parray [1]= 2;
    table.setRowSelectionInterval(parray[0], parray[0] );
    table.setRowSelectionInterval(parray[2], parray[2] );
    //for each iteration a single row will be selected
    //coz the starting and ending indeces are same ie
    (parray[0],parray[0])
    but when this code is run only the 2 nd row gets selected , what abt the 0'th row???
    please help.
    Thanx.

    sorry
    there is a small correction in the above code
    //indeces of rows to be selected in the table are stored
    //in parray
    int[] parray = new int [2];
    parray [0]= 0;
    parray [1]= 2;
    table.setRowSelectionInterval(parray[0], parray[0] );
    table.setRowSelectionInterval(parray[1], parray[1] );
    //for each iteration a single row will be selected
    //coz the starting and ending indeces are same ie
    (parray[0],parray[0])

  • How to set the default tree node in JTree?

    I want to set a default tree node in JTree when start the program,
    what is the method or the function to call?
    Thanks~

    If you by "default" mean "selected", then you can use one of the setSelectionXXX methods in the JTree API.
    If you by "default" mean something else, never mind this post :-)

  • How to Make the Default Button Marker Not Show Upon Launching...

    I am trying to only have the markers show up on the menu item when you roll over it.  However, when the menu is first launched, the marker is automatically showing up on the first button.
    I have selected "None" as the default menu button in the menu config.  I am also using Photoshop to make the menu and creating the (+) buttons there.
    Any help would be greatly appreciated.
    Thanks.

    Create an invisible button (turn off the visibility of all layers) and
    set it to use Highlight Group 2 (edit the Menu Color Set).  Set the
    opacity of all the highlight states to 0%.  Make the invisible button
    the default button.

    Now we know modify both HorizontalGridLinesBrush and VerticalGridLinesBrush we can change the DataGrid cell separator color.
    Following your suggested, we modify the DataGridCell as following:

  • How to make the default shutdown operation to be a forced one?

    Just recently I clicked on shut down and went with my business, only to find out on return that OS X didn't shutdown the laptopt because "firefox prevented" it from doing so. What a BS.
    Is there a way to change the default parameters for the shutdown execution?

    No.
    You could go into the Terminal and use the "sudo shutdown -h now"

  • 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

    Steve556 wrote:
    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.
