How to set the width: IF_WD_SELECT_OPTIONS- add_parameter_field

Hi everyone,
I would like to know if there's a way to set the width of UI controls defined for IF_WD_SELECT_OPTIONS.
In particular I've created a selection screen using
  wd_this->m_handler_simple_left->add_parameter_field( i_id = 'CONTRACT_DESCRIPTION'  i_value = lr_field
                                                    i_description = 'Contract description'
                                                    i_within_block = 'BL01'  ).
but I'm unable to set the width of this field and the final rendering isn't very nice at all (all input fields have different data types and different size).
Thank you.
Regards

Hi,
I think we dont have any width type parameter to set width in selectoptions. The width comes directly from Domain.
Cheers,
Kris.

  • How to set the width of DataGridColumn dynamically?

    What I want to do is, load data from a text file and put into a DataGrid component, the fields of ech record in the text have fixed length, and are seperated by a space, like this:
    personal.txt
    50 Uvwxyz  Male    123456789
    60 Hijklmn  Male    67890123456789
    30 Abcdefg Male    123456789012345
    40 Opqrst   Female 987654321012345678
    the configuration file is column.xml:
    <dgcolumn>
         <personal>
              <len>20</len>
              <title>Name</title>
         </personal>
         <personal>
              <len>3</len>
              <title>Age</title>
         </personal>
         <personal>
              <len>6</len>
              <title>Sex</title>
         </personal>
         <personal>
              <len>20</len>
              <title>IdNumber</title>
         </personal>
    </dgcolumn>
    First I load the column.xml into an arrColumn, then read the personal.txt and seperate the record by the width( "len" in the xml file ), and put the seperated fields into another arrField, set the arrayFld as the dataProvider of a DataGrid, thus, the title can be showed as the headerText of the DataGrid and the data can be loaded correctly.
    private function handleComplete( event:Event ):void
         var arrField:Array = new Array();
         var arrFile:Array = loader.data.split(/\n/);
         for( var i:int = 0; i < arrColumn.length; i ++ )
              arrField[i] = convIcom( arrFile[i] );
         adgFile.dataProvider = arrField;
         trace( "The data has successfully loaded" );
    private function convIcom( strRecord:String ):Object
         var key:String = null;
         var dataField:String = null;
         var offset:int = 0;
         var obj:Object = new Object();
         if( strRecord.length > 0 )
              for( var i:int = 0; i < arrColumn.length; i ++ )
                   dataField = strRecord.substr( offset, arrColumn[i].len );
                   key = arrColumn[i].title;
                   obj[key] = dataField;
                   offset += arrColumn[i].len + 1;
         return obj;
    <mx:DataGrid x="10" y="100" width="400" id="dgFile" />
    The problem is, the width of the DataGridColumn is average, how to set the column width by the length of each field? I can calculate the rate of each field ( field / fields ), but I don't know how to change the property of the DataGridColumn.width.
    Thanks for helping.

    In the above post, I pasted an old version of personal.txt, so I paste it again:
    personal.txt
    Uvwxyz  50 Male   123456789
    Hijklmn 60 Male   67890123456789
    Opqrst  40 Female 987654321012345678
    Abcdefg 30 Male   123456789012345
    And I have another question, when the data is loaded into the DataGrid, the fields of each record are ordered in alphabetical order ( the "Age" column will appear firstly, then "IdNumber", "Name", "Sex" ), not as the order in column.xml, how to make it keep the sequence of the xml file?
    Thanks again.

  • How to set the width of a shuttle?

    Hi
    I have a group which is shown in intersection-shuttle style but the problem is that it breaks some rows into two lines and i want to make the shuttle a bit wider. How could I set the width of the shuttle. Apparently the Group Width attribute of the group doesn't work for this.

    You could try this using the inlineStyle property of the shuttle component in the generated page. Not sure that works though. You better ask this on the JDeveloper forum.
    If it works you can create a custom template to include the inlineStyle property during generation.

  • JTable Model   --  How to set the width of columns

    Hello,
    This project of mine is due in 2 days. :(
    I am using AbstractTableModel and I can't figure out how to set the columns' width inside my JTable?
    This following code does not work.
    int vColIndex = 1;
    TableColumn col = table.getColumnModel().getColumn(vColIndex);
    int width=399;
    col.setPreferredWidth(width);Please remember, that I'm using AbstractTableModel and not just simple JTables.
    Thanks in advance.

    The DataModel (AbstractTableModel or otherwise) has nothing to do with the table column size. The DataModel is used to store data.
    When you create a JTable using a DataModel then a TableColumn is created for each column in the DataModel using a default column size. The normal order of creation would be:
    TableModel model = new DefaultTableModel(...);
    JTable table = new JTable(model);
    Now that the table and table columns are created you can change the size of the columns:
    int vColIndex = 1;
    TableColumn col = table.getColumnModel().getColumn(vColIndex);
    int width=399;
    col.setPreferredWidth(width);
    So your code looks ok.
    However, if somewhere in you code you do:
    a) table.setModel(...)
    b) fireTableStructureChanged();
    then the table columns are recreated based on the current DataModel and the table column size would be reset to the default values.

  • How to set the width and heigh in the popup window

    Hi All,
    I tried to show a report in a popup window style.
    In the column link section, I defined the URL like the following:
    javascript:popupURL('f?p=&APP_ID.:128:&SESSION.::&DEBUG.::P128_PAY_RATE,P128_PAY_TERMS:#PAY_RATE#,#PAY_TERMS#'). how and where to set the height and width for page 128?
    Thank you,
    spark

    Here is a sample of the JavaScript function I re-use that opens a popup window. You'll notice that it includes the width and height of the popup window:
      function callTCPopup (formItem1) {
        var formVal1 = formItem1;
         var url;
      url = 'f?p=&APP_ID.:1111:&APP_SESSION.::::P1111_TC_ID:' + formVal1;
      w = open(url,"winLov","Scrollbars=1,resizable=1,width=800,height=600");
      if (w.opener == null)
      w.opener = self;
      w.focus();
      }You could also look at using a Modal Page (Skillbuilders' plugin - watch the video for use).

    Follow some CSS tutorials to learn more about it.

    Then you're doing or interpreting something wrong. The methods are actually there. I can play with them in my playground and they are also described in the the HtmlCommandButton API: http://java.sun.com/javaee/javaserverfaces/1.2/docs/api/javax/faces/component/html/HtmlCommandButton.html

  • SAPUI5: How to set the appearance of Table control?

    Hi there,
    I have a table on my app UI. Now I want simply show the table grid lines (currently, the vertical lines between columns are not shown). Any idea?
    Furthermore, how to set the width of the bord lines or even teh color of the lines?
    Thanks very much in advance!
    Dong Zhu

    Hi,
    The demo link provided by Chandra uses Blue Crystal theme, hence it shows the vertical lines between the columns of the table. If you are using Gold Reflection theme, then to get the vertical lines, you need to play with CSS. Add the below snippet of CSS between <head></head> of your html file.
    <style>
    .sapUiTableTr>td {
                  border-right: 1px solid #cccccc !important;
    </style>

  • How to set the BARCODE width and length for label printing..

    Hi All,
    How to set the Code 39 barcode label format in the sizxe of 0.20" * 1.4". By default while printing barcode size exceeds my current requirement. Please let me know to customize the size of barcode labels.
    Thanks.

    I don't know what you mean by "Code 39" because my Output Designer software doesn't offer that barcode (or do you mean "code 3 of 9?). In any case, are you trying to control the size of the text (which is what I think of when you refer to "label")? If you are, then just change the font & size. If you are wanting to modify the physical characteristics of the barcode itself (height & length for a certain number of characters) then you are probably out of luck. Or at least in for some trial & error.
    There are a series of "barcode.xxx" files in the 'config' folder where Output Designer was installed to. These are text files that contain the physical characteristics of the various barcodes for various printers. The parameters that you would be interested in is the height and width of the bars (black & white). For example, a barcode might be defined as .400 high with narrow bars 3 "dots" wide, wide bars 9 "dots" wide and white space the same or different. Presumably changing these values would affect the generated barcode. For example, in this example the wide bars are 3 times the width of the narrow bars so I would assume that relationship would have to remain. To make the resulting barcode shorter you would then use 2 for the narrow and 6 for the wide.
    You would have to make the change in the file(s) that would be used for your printer(s).
    There are four width values for each of the parameters. Most of the barcodes only use 2 but some have 4. I'm assuming that when there are 4, like in "4 8 12 16", that the barcode definition has 4 different widths of bars and/or spaces.
    There is no guarantee that the scanning hardware & software will "see" and interpret the resulting barcode correctly.
