How to get the textLines in a RichText control

I am trying to get hold of the individual lines that make up the RichText control once I set the text on it.  I am able to see the RichText.textLines property in the debug window (by creating a watch expression) - but when I try to access it in code, the compiler throws an error. 
I even created a subclass of RichText and tried writing a getter for it, but still the same compiler error:
"Attempted access of inaccessible property textLines..."
Is there any other way I can do this?
Thanks,
Om

Few of my use cases:
1.  Since I am matching Flash to follow some other text rendering algorithm (SVG/Batik in this case), I would like more control over where to break, etc.  I have a few edge cases where I need to know what goes in each line.
So I plan to inspect each TextLine and based on the TextLine.rawTextLength find out what text goes in each line. I would alter the text of the RichText control based on my set of rules.
2.  Sometimes the RichText control displays partial last lines even when truncation is turned on.  I want to manually add the textHeights of each line and ensure that none of them go out of the bounds.
I did try using a StringTextLineFactory to just create my own text control.  But I ran into some other issues(setting the firstBaselineOffset).  Hence i am using RichText control and using these techniques to gain fine control over the text's appearance.
Thanks,
Om

  • How to get the menu reference of a control while runtime

    Hello...
    i want to disable the control's short-cut menu programmatically. i could do it by using the event structure and 'shortcut menu activation' event.
    this is why i am asking about getting the menu reference if individual control.
    is there any other way out without using event structure?

    No. You have to use the event. But if you simply disgard the activation, you
    don't need to change it's run time menu. You'll need the event structure
    anyway to catch the selected menu item.

    An yet you keep getting suggestions of how to set the focus.   I looked through the API documentation and I don't see anything that would suggest you can request to see where the current focus is.  Perhaps someone might still come along with a solution, but my hopes wouldn't be too high at this point.  I can pass the requirement onto Product Definition, as the use case does seem interesting.  Perhaps it is something we have even considered in the past. 
    But for now, there might be a better way to solve your problem.  It will probably mean redesign the interaction.  What exactly are your requirements?  Do you need to be able to get the data in a particular cell of table when a button is clicked?  Just throwing out some ideas here, but maybe just use the lead selection to select the row, but then have a button choice to choose the action associated with the column you want. A hack for sure - but it might work.  Also it doesn't help you right now, but in the near future update to NetWeaver 7.0, WDA does have a onColSelect event for the table.

  • How to get the name of a duplicated control or created control and add a callback to it

    Hi All,
    Depending on how many input points I need, I am duplicating a numeric or string input with the DuplicateCtrl function. My question is, how do I get the name and id of the control that was just created, and how can i assign a callback to it? Alternately, would it be better to create a fresh ctrl instead of duplicating?
    Thanks in advance!
    Solved!
    Go to Solution.

    Hi TurboMetrologist,
    why are you trying to get the control constant name? Keep in mind that you cannot use that name to address the control; control names are actually simply macros in the include file associated to the UIR, that is, the compiler preprocesses the code and wherever it finds PANEL_CONTROL names substitutes the corresponding numeric value as parameters to the functions (and consequently 'control' parameter is an int and not a char*)
    That is why NewCtrl () or DuplicateCtrl () functions return a control ID: it is the handle to the new object, our only way to manipulate it. You will need to store this handle into a non-volatile memory so that you can access it durng program life.
    Additionally, there are other ways to assign some particular meaning to a control than swiching on the control constant name. You could for example use the callbackData parameter to differentiate between different copies of a control.
    Let me explain with an example. You told that you need several inputs (dynamically created as you don't know in advance how many of them to use); a clean solution could be to:
    Design a master copy of one control in the UIR editor, where it is easy to customize it; assign also a callback function, if it has to be common to all copies of the control
    Programmatically assign a callbackData value to that control, e.g. SetCtrlAttribute (..., ..., ATTR_CALLBACK_DATA, (void *)1);
    Duplicate the control and then assign a different callbackData
    for (i = 2; i < 5; i++) {
       handle = DuplicateCtrl (...);
       SetCtrlAttribute (..., handle, ATTR_CALLBACK_DATA, (void *)i);
    By operating this way, every time the control callback is fired by any control it will receive the assigned callbackData, and you will be able to differentiate your code by a simple switch:
    switch ((int)callbackData) {
       case 1:    // The master control
          break;
       case 2:    // The first duplicated control
          break;

  • How to get the values from popup window to mainwindow

    HI all,
       I want to get the details from popup window.
          i have three input fields and one search button in my main window. when i click search button it should display popup window.whenever i click on selected row of the popup window table ,values should be visible in my main window input fields.(normal tables)
       now i am able to display popup window with values.How to get the values from popup window now.
       I can anybody explain me clearly.
    Thanks&Regards
    kranthi

    Hi Kranthi,
    Every webdynpro component has a global controller called the component controller which is visible to all other controllers within the component.So whenever you want to share some data in between 2 different views you can just make it a point to use the component controller's context for the same. For your requirement (within your popups view context) you will have have to copy the component controllers context to your view. You then will have to (programmatically) fill this context with your desired data in this popup view. You can then be able to read this context from whichever view you want. I hope that this would have made it clear for you. Am also giving you an [example|http://****************/Tutorials/WebDynproABAP/Modalbox/page1.htm] which you can go through which would give you a perfect understanding of all this. In this example the user has an input field in the main view. The user enters a customer number & presses on a pushbutton. The corresponding sales orders are then displayed in a popup window for the user. The user can then select any sales order & press on a button in the popup. These values would then get copied to the table in the main view.

  • How to get the table of value field? and can we expand the technical limits

    Dear
    I have created value field in COPA with KEA6. And now, I need the table which the value fields are saved. Yet, I have tried a lot to find it and get failure? Can any guy help me? Please tell me how to get the table of a value field.
    And another question is that, can we extend the technical limits for the number of value field for ECC6.0?
    We have a note for R.4.x Please see below:
    OSS note 160892
    You can display the length of a data record using Transaction KEA0 ('Maintain Operating Concern'). After you have navigated to the 'Characteristics Screen' or to the 'Value field Screen' choose menu path 'Extras -> Technical Limits'.
    The maximum displayed here under 'Length in bytes on the DB' is the maximum length permitted by the Dictionary. The reserve required for the release upgrade must be subtracted from this value.
    To increase the allowed number of the value fields, increase the value that is assigned to field ikcge-bas_max_cnt (FORM init_ikcge_ke USING fm_subrc, approx. line 165) in Include FKCGNF20. It specifies the number of the possible value fields. The corresponding part of the source code is attached to the note as a correction.

    how to extend the limit of value numbers? please see the original question.

  • I downloaded and bought a movie from iTunes on my iPad and now want the same movie on my MacBook Pro but its not offering me to download it, it giving me the options of buying it which I already did. How I get the movie onto my MacBook?

    I downloaded and bought a movie from iTunes on my iPad and now want the same movie on my MacBook Pro but its not offering me to download it, it giving me the options of buying it which I already did. How I get the movie onto my MacBook?

    You can connect the iPad to your Mac's iTunes and do File > Devices > Transfer Purchases, that should copy it over to the Movies part of your library.
    Depending upon what country that you are in, and whether the film studio allows it, you might also be able to re-download it on your Mac via the Purchased link under Quicklinks on the right-hand side of the iTunes store home page.

  • How to get the value from databank

    Hi,
    How to get the value from databank? and how to set the same value to visual script object?
    thanks,
    ra

    Hi,
    You can use GetDatabankValue(HeaderName, Value) to get the value from databank and SetDataBankValue(HeaderName, Value) to set the value to databank.
    You can refer to the API Reference to see list of associated functions and techniques we can use with related to Data Bank.
    This is the for OFT but if you are using Open Script then you have direct access for getting the databank value but when it comes to setting a value you have to use File operation and write you own methods to do the set operation.
    Thanks

  • How to get the value from Advanced table

    Hi,
    In the Advanced table have 2 LOV fields, I need LOV field value dynamically in the controller to validate the save button, if iam not selected any value in lov save button will not allow to save the data. In the table i am using 'Add another row'. How to get the lov field value in the process form request??? and how to do this requirement
    Thanks
    Naresh

    1. You can specify required property on LOV field to "yes". For events where you wish to disable the client side validations, set the property disable client side validation to "true".
    2. If above behavior is not what you are looking for, then you need to handle in AM and not CO.
    a. Call an AM method from CO.
    b. In that AM method, get handle of VO.
    c. Iterate the VO Rows and check for your validation rules.

    Dear All,
    Good Afternoon,
    I want to set the 0 value to the fields at the time of page loading.
    For this,
    i tried the following ways
    pageContext.putParameter("fieldid",0);
    and
    OAMessageTextInputBean bean1=(OAMessageTextInputBean) webBean.findChildRecurssive("fieldid");
    bean1.setValue(pageContext,0)
    for getting the values i used
    String id=pageContext.getParameter("fieldid");
    but i returns null values only while it has 0 value.
    how can get the 0 value from that field

    Hi,
    In order to set values you should use:
    OAMessageTextInputBean bean1=(OAMessageTextInputBean) webBean.findChildRecurssive("fieldid");
    if(bean1!=null)
    bean1.setText("0");
    and in order to grab the values from the fields
    String id=(String)pageContext.getParameter("fieldid");

    Hi Rajeev,
    To retrieve a FilterContainer you will need to traverse the report structure:
    ReportStructure boReportStructure = boDocumentInstance.getStructure();
    ReportContainer boReportContainer = (ReportContainer) boReportStructure.getReportElement(0);
    FilterContainer boFilterContainer = null;
    if (boReportContainer.hasFilter()) {
         boFilterContainer = boReportContainer.getFilter();
    } else {
         boFilterContainer = boReportContainer.createFilter(LogicalOperator.AND);
    Calling boDocumentInstance.getStructure() will retrieve the entire structure for the document.
    Calling boReportStructure.getReportElement(0) will retrieve the structure for the first report of the document.
    Hope this helps.
