Creating a Custom SAPscript Editor

I am trying to create a custom SAPscript editor and I'm having problems. We are on SAP 640.
We use texts to store notes against invoices recording details of the dunning process. Our users have ask if we can tailor the notes so that users can insert new notes against an invoice but not update or delete old notes. I have tried to do this by creating a custom editor EDIT_TEXT_FORMAT_XXXXX where XXXXX is ZGTENO a text format that has been set up against text object BELEG. Unfortunately the new module is never called.
For most text objects SAP picks up the text format  and moves it into the SAPscript header and this field in the SAPscript  header is used to call the custom editor. For example in program sapfv45t include FV45TFDB_TTXER_SELECT_CREDM   text format is in gt_tdtexttype or lv_tdtexttype  one of these fields is then moved into the SAPscript header field xthead-tdtexttype which is used in function group STXD function module EDIT_TEXT (the field is in chead-tdtextline) to decide whether to call the standard editor (function FULL_SCREEN_NEW) or a custom editor but for text object BELEG it gets the text format but never moves it to the SAPscript header (for example see program sapfv45t include FV45TFDB_TTXER_SELECT_BELEG it gets the text format in lv_tdtexttype but doesn't move it to xthead-tdtexttype so it can't be used to call a custom editor) so it looks as if a custom editor cannot be used with text object BELEG, is this correct or am I missing something?
I can see my new text format ZGTENO being picked up in the debugger but because it isn't moved into the SAPscript header it doesn't call my function module, it always calls the standard editor.

  • Customized JComboBox Editor for JTable

    Hi,
    I am new to swing development and have gotten my self stuck on an issue. Basically I have a JTable that is dynamically populated from the database, in which one of the columns has a customized JComboBox Renderer and Editor. The default values load up fine when the page loads up but when I selected a new value in the combo box and select a new row in the JTable, the combo box defaults back to the original value. How can I make sure that the new selection is maintain.
    Thanks, Anthony
    Here are my Driver, Renderer and Editor:

    First off, I wouldn't subclass JComboBox to create a custom renderer/editor. I would have a renderer/editor component that makes use of a JComboBox. But that is just me.
    In order for setSelectedItem to work, the items in your combo box have to compare against each other correctly with equals(). Since you are creating new instances, your objects (even though they contain the same data) are going to be different instances and aren't going to be considered equal. Write your own equals() method in your CashFlow object that tests for equality based on the actual values in the objects and you should be fine.

  • Problem sorting JTable with custom cell editor

    Greetings,
    I have created a JTable with a JComboBox as the cell editor for the first column. However, I couldn't simply set the default cell editor for the column to be a JComboBox, since the values within the list were different for each row. So instead, I implemented a custom cell editor that is basically just a hashtable of cell editors that allows you to have a different editor for each row in the table (based on the ideas in the EachRowEditor I've seen in some FAQs - see the code below). I also used a custom table model that is essentially like the JDBCAdapter in the Java examples that populates the table with a query to a database.
    The problem comes when I try to sort the table using the TableSorter and TableMap classes recommended in the Java Tutorials on JTables. All of the static (uneditable) columns in the JTable sort fine, but the custom cell editor column doesn't sort at all. I think that the problem is that the hashtable storing the cell editors never gets re-ordered, but I can't see a simple way to do that (how to know the old row index verses the new row index after a sort). I think that I could implement this manually, if I knew the old/new indexes...
    Here's the code I use to create the JTable:
    // Create the Table Model
    modelCRM = new ContactTableModel();
    // Create the Table Sorter
    sorterCRM = new TableSorter(modelCRM);
    // Create the table
    tblCRM = new JTable(sorterCRM);
    // Add the event listener for the sorter
    sorterCRM.addMouseListenerToHeaderInTable(tblCRM);
    Then, I populate the column for the custom cell editor like this:
    // Add the combo box for editing company
    TableColumn matchColumn = getTable().getColumn("Match");
    RowCellEditor rowEditor = new RowCellEditor();
    // loop through and build the combobox for each row
    for (int i = 0; i < getTable().getRowCount(); i++) {
    JComboBox cb = new JComboBox();
    cb.addItem("New");
    //... code to populate the combo box (removed for clarity)
    rowEditor.add(i,new DefaultCellEditor(cb, i))); //TF
    } // end for
    matchColumn.setCellEditor(rowEditor);
    Any ideas how to do this, or is there a better way to either sort the JTable or use a combobox with different values for each row? Please let me know if more code would help make this clearer...
    Thanks,
    Ted

    Well, I found a solution in another post
    (see http://forum.java.sun.com/thread.jsp?forum=57&thread=175984&message=953833#955064 for more details).
    Basically, I use the table sorter to translate the row index for the hashtable of my custom cell editors. I did this by adding this method to the sorter:
    // This method is used to get the correct row for the custom cell
    // editor (after the table has been sorted)
    public int translateRow(int sortedRowIndex)
    checkModel();
    return indexes[sortedRowIndex];
    } // end translateRow()
    Then, when I create the custom cell editor, I pass in a reference to the sorter so that when the getTableCellEditorComponent() method is called I can translate the row to the newly sorted row before returning the editor from the hashtable.

  • Creating a custom drum staff for score and hyper editor

    Can anyone clearly explain, how to create a custom drum staff to use in Score page? Each manufactor uses a different mapping. I would like to create a drum score for Korg, Yamaha, BFD, Superior etc.
    I often change drum kits (BFD, Yamaha, GM, Korg, etc) while working on a song. I want to create a drum staff style to accomodate each of these. So the drum notation will be standard drum notation.
    There is a GM drum staff style in Logic. When I use a GM kit, it works fine. But the best drum instruments use several articulations of each drum. I can't figure out how to edit it a drum staff to display what I need.
    For instance Kik is normally C1. But some some drum instruments might use B0, C1, G5, C-1, all playing different articulations of kiks. I need to create a staff style which will show all these different notes as showing up on the bottom of the drum staff (standard drum notation)
    I can create a Hyper drumkit for each different brand of drum . But I can't figure out how you incorporate that into the score editor. You must have to create a custom drum staff. But it eludes me....
    Thanx...

    Steps to create a HR Infotype:
    1) Go to Transaction PM01.
    2) Enter the custom Infotype number which you want to create (Should be a 4 digit number, start with 9).
    3) Select the 'Employee Infotype' radio button.
    4) Select the 'PS Structure Infotype'.
    5) Click on Create... A separate table maintenance window appears...
    6) Create a PS structure with all the fields you want on the Infotype
    7) Save and Activate the PS structure
    8) Go back to the initial screen of PM01.
    9) Click on 'All' push button. It takes a few moments.
    10) Click on 'Technical Characteristics'. Infotype list screen appears
    11) Click on 'Change'(pencil) button
    12) Select your Infotype and click on 'Detail' (magnifying glass) button
    13) Give 'T591A' as subtype table

  • A method to create completely customized photo book page templates from scratch in Lightroom 5

    I was able to successfully create completely customized Lightroom 5 page templates (including altering the number of, positions, and sizes of pictures) by making edits to the templatePages.lua file(s) in the Lightroom directory tree.  I have never heard of the LUA file format before, but it is ASCII and looks somewhat like XML, so it was fairly easy to decipher.  Here is a high-level description of how I did it.  This applies to Lightroom 5 on Windows 7.  If this doesn't make any sense to you, then don't try it - you're likely in over your head.  Although my description is brief and lacking in detail, it should enable someone who is capable of handling this to figure it out with a little of careful trial and error.  Do this at your own risk - if you screw-up your installation, catalog, or computer, it's your own fault.  It all worked great for me.
    First, open the "<lightroom 5 install directory>\Templates\Layout Templates" folder.  Then navigate to the template set that contains the template you would like to use as a starting point for the new template.  For example, "12x12-blurb\clean12x12".  Make a back-up copy of the templatePages.lua file in case you mess something up and want to revert.
    There will be a bunch of .jpg files in this directory that each contain a preview image of the layout that carries the same name as the .jpg file.  Find the one that you would like to use as a starting point.  Take note of the name of the file, which is probably something similar to "page_26_preview.jpg".   Duplicate the file and rename it to something unique, such as "dummy_preview.jpg".  It's just temporary, so it doesn't matter what name you pick, provided it is a legal file name with no spaces.
    Next, open the templatePages.lua file in a text editor.  I suggest using one that can automatically recognize and format ULA (such as Notepad++, which is open source and free to use).  Then search the file for the unique portion of the file name you took note of earlier, such as "page_26".  It will point you to a section in the LUA file that describes that particular template.  Carefully copy that entire section, including a balanced number of brackets (starting with the two brackets and commas before "children" and ending with the one bracket and comma after the "title" line.  Paste the copied text into the end of the file on a new line immediately following the bracket and comma after the "title" field for the last page template section (right near the end of the file).  Change the "previewName" field to the name of the preview file copy that you created ("dummy_preview.jpg" for me) and the "name" field to the name of the new template you're creating ("dummy" for me, since it is just temporary).  Next change at least one of the hex characters in the "pageID" field such that the new template will have a unique page identifier.
    Now you can make edits to the photo and text fields included in the new section, using other templates in the template file as examples.  "x" and "y" fields are coordinates (in pixels) for the bottom-left corner of the picture or text field, "height" and "width" are the width of the field in pixels.  The fields should be mostly self-explanatory, but make sure that the "photoindex" fields are filled-in starting from 1 to N, where N is the number of pictures in the template, with no duplicates or gaps.  They do not need to be in order.  Treat the "textIndex" fields similarly for text fields.  If you want to add an additional picture or text field, simply copy the section describing a picture or text field from another template and paste it, carefully, into the new template that you are creating.
    Once you are done, save the file (you may get interference from Windows UAC, in which case save the file elsewhere and the move it back to the correct directory).  Then open Lightroom.  Create a new photobook, and choose the new template for one of the pages, remembering that the preview image will look like the JPG that you copied.  Voila!  If you didn't screw anything up, you should see a page based on your new template.  Then right-click the page and select "Save as custom page", which will cause a fresh preview file to be created for your new template and your template to be copied to the "custom pages" section of the template menu.  The new section you added to the "templatePages.lua" and the "dummy" preview file can now be deleted, since they are no longer needed.  I save them so that I may simply overwrite them the next time I need to create a customized template.
    Enjoy, and please share any clarifications, corrections, or enhancements to my process.

    This post was great!  Thank you so much.  But I am hoping you know one more thing related to this.  In the "transform" section of the definition (where the x/y coordinates are set along with height and width) there is an option called "angle".  I was hoping that changing this value would allow me to offset the angle of the picture.  However, if I put any value there other than 0 the template becomes unusable.
    Do you happen to know what this option does?
    I haven't looked into the files, so this is just a guess based on how some graphic applications work. It's common to think of rotating a shape as pivoting around a center point, but It's possible that the file sets a value for the rotation point not at the center. In some graphics applications, you can set a shape's pivot at any corner or in the middle of any side, of the rectangle that contains the whole shape.
    So, your value may be rotating the shape around a pivot that moves the shape into some area that upsets the behavior of other shapes. Just a thought.

    Peter's point is a good one.  I would also assume that the "angle" property allows you to rotate an image, but I haven't tried it myself.  One thing to investigate - are there any page templates included in LR that have image placeholders that are at an angle (I don't recall any, off-hand)?  If so, looking at the associated .lua file could provide insight into how an angled image placeholder should be described.

  • How do I set up Premiere Elements 13 as the custom external editor for Lightroom 5?

    Situation
    I own Lightroom 5.6 and I'm experienced. I've just bought Premiere Elements 13 and I'm a video-editing virgin (be gentle with me). I've spent a day experimenting, reading, watching videos and I'm still stuck (I've tried reasonably hard to solve my own problem).
    Problem
    I've tried to set up the custom external editor in Lightroom 5 to send photos to Premiere Elements, so that I can incorporate images into movies. Having set it up, when I use it by selecting Photo/Edit In/Premiere Elements 13/, there is an exciting lull as a copy of the image is created and appears in LR, then Premiere Elements launches, then what??? There is no clue as to what has happened to the image regarding its import into Premiere Elements 13. It doesn't appear on the screen, it doesn't appear in the Organizer, it's no-where to be seen, other than in LR!
    Resolution sought:
    Can anyone tell me
    1. Is it possible to use Premiere Elements as an external editor in LR5 ?
    2. What are the precise settings should be for each field?
    3. If I configure it correctly, what does good look like: what should I expect to see happen in Premiere Elements?
    I don't know if this is relevant: MacBook Pro 16GB 2.8Ghz i7, 750GB SSD (i.e. plenty of space, plenty of horsepower), OS X 10.9.5
    I also don't know if I this is the right place for my question (Adobe directed me here) so please don't shout at me if I've come to the wrong place (I expect if I get no joy here, when I post it to an LR forum, they'll shout at me too :-)

    I do not have Lightroom 5 or other version of it. I did do some work on an earlier version tryout of it.
    And, I believe now as then, that the answer to your question is No. Bottom line, if there is integration
    to be found between Lightroom, it is between Photoshop Elements and the Elements Organizer, not the Premiere Elements Editor.
    The following is the extent of my travels through Lightroom with focus the Slideshow Module.

  • Creating a custom component in multisim using *.lib and *.olb files

    i have  *.lib and *.olb files for a pspice model. which file i have to you while creating a custom component in multisim.

    Hello,
    Thanks for your question. In order to create simulatable custom components in Multisim you need a SPICE model (Multisim can also understand PSpice Models). The file format for SPICE model can be different according to the manufacturer, for instance: *.cir, *.lib, *.llb. At the end of the day these files are text files that you can open with a text editor, therefore, you can simply copy and paste the model in Multisim.
    Here are two good resources on component creation:
    Component Creation 101
    Creating a Custom Component in NI Multisim
    When you reach the step where you need to enter the SPICE model, simply open the *.lib or *.olb file with a text editor, and copy and paste the model.
    Hope this helps.

    You don't have to buy an Apple keyboard, but you probably need at least to buy a keyboard that connects via proper USB instead of through some Windoze-world adapter, which probably requires a driver that's not available for the Mac OS.
    The Apple Bluetooth KB and Magic Trackpad make a fabulous combination for use with any MacBook Pro that spends a lot of time in clamshell mode, because the trackpad works exactly like the built-in trackpad. So there's no transition adjustment to make when you pack up your MBP and go portable with it.

  • Custom icon editor BUG

    If you use a custom Icon editor (as shown here and here), and you want to create a smaller Icon this will be meaningless.
    Because the lv_icon interface only allows you to generate the 2-colour and 256 colour icon. The 16 colour icon will be untouched so the total size of the icon will still be 32x32 pixels.
    I consider this a serious bug in the lv_icon customization scheme.

  • Creating a customized signature on photos

    i am new to Adobe photoshop, and cannot figure out how to create a customized logo/signature to place on all my photos - can anyone help ?

    Logos will probably need to be created in PNG format by a pixel-based editor like Photoshop or Photoshop Elements or a drawing program like Illustrator or CorelDraw. Lightroom does not have the capability for this type of Logo creation
    Once created you can use the Watermark feature in Lightroom to apply it to all your images on Export/Print/Slideshow/Web versions.

  • BC - Word-Processing in the SAPscript Editor

    Hi,
    Could anyone tell me how the Link functionality in the SAPscript Editor is working?
    Regards,
    Morten

    Thanks.  Well there's a little bit of doco at:
    http://help.sap.com/saphelp_nw04/helpdata/en/a4/d47f0f49e111d189730000e8322d00/frameset.htm
    but basically the "link" option calls function 'DOCU_LINK_BUILD' which allows you to create a "hyperlink" to another document e.g. in the editor you could type
    here is a link
    and put your cursor on the word "link" and chose Insert  > Link, and in the popup identify that you want it to go to (say) program ZLOCAL_JC_SDN_PROG2, and the following will be inserted in your SAPScript editor:
    <DS:RE.ZLOCAL_JC_SDN_PROG2>link</>
    and when you display this documentation you see the work "link" highlighted.
    Is this the sort of info you needed?
    Jonathan
    (there should be a slash showing in the angle brackets after the "link" word in the example above)

  • JTable custom cell editor focus problem

    Hi I have created a JTable (using Java 1.4.2) and have three cell Editors, one is a JFormattedTextField, one is a JComboBox and one is a custom cell editor.
    When I press tab I can select the cell with the JFormattedTextField and when I start typing the JFormattedTextField accepts my input and it is displayed in the cell. This is the type of behaviour I would like but it does not seem to work for my other 2 cell editors:
    When I tab to the JComboBox cell I can see that the cell is selected but typing or using the arrow keys does not allow me to select a new value in the JComboBox. (I have also tried typing space or enter to activate the JComboBox whilst the cell is selected.) The only ways to select a new value at the moment is to first click on the cell with the mouse and then use the keyboard to select a new value. It is like the actual JComboBox is not receiving the focus? Does anyone know how to solve this problem?
    I also seem to have the same problem with my custom cell editor. My custom editor is a JPanel which contains JFormattedTextField again I can tab to the cell and see that it is selected but to activate the JFormattedTextField I have to actually select it with the mouse.
    I have been stuck on this for some time so if any one has any suggestions they would be much appreciated !

  • JTable custom cell editor losing focus

    This is a followup to Re: Tutorial on AWT/Swing control flow wherein I ask for pointers to help me understand the source of focus-loss behaviour in my JTable's custom cell editor.
    I have done some more investigations and it turns out that the focus loss is a more general problem with custom cell editors which call other windows. Even the color-picker demo in the JTable tutorial at http://download.oracle.com/javase/tutorial/uiswing/examples/components/index.html#TableDialogEditDemo has this problem, IF you add a text field or two to the layout BEFORE the table. The only reason the table in the demo doesn't lose the focus when the color-picker comes out is because the table is the only thing in the window!
    Here is the demo code, augmented with two text fields, which are admittedly ugly here but which serve the desired purpose:

    }When you come back from choosing a color, tf1 is given the focus, instead of the table. This is because bringing the color picker window to the front causes a focus lost event for the cell editor component; it's temporary, as it should be, so why on earth is the system losing track of who has focus in the window??
    I see the following in Window#getMostRecentFocusOwner():
      public Component getMostRecentFocusOwner()
        if (isFocused())
          return getFocusOwner();
        else
          Component mostRecent =
            KeyboardFocusManager.getMostRecentFocusOwner(this);
          if (mostRecent != null)
            return mostRecent;
          else
            return (isFocusableWindow())
                   ? getFocusTraversalPolicy().getInitialComponent(this)
                   : null;
      }My app has a custom focus traversal policy, so I'm able to see who is being called, and indeed, getInitialComponent() is being called. Clearly, the KeyboardFocusManager is actually losing track of the fact that the table was focussed at the point where control was transferred to the color picker! This strikes me as completely unreasonable, especially since, as noted, this is a temporary focus loss event, not a permanent one.
    I'd be grateful for any wisdom in solving this, since similar behaviour to this little demo -- without focus loss, naturally -- is an essential part of my application.

    Looks like it is because the 'restore-focus-to-previous-after-modal-dialog-close' is in a later event than when the control returns to the action performed (which I guess makes sense: it continues the action event handler and the focus events are handled later, but I needed two chained invoke laters so it might also be that the OS events comes later).
    The following works for me (in the actionPerformed edited):
               // create the dialog here so it is correctly parented
               // (otherwise sometimes OK button not correctly the default button)
               dialog = JColorChooser.createDialog(button, "Pick a Color", true,  //modal
                            colorChooser, this,  //OK button handler
                            null); //no CANCEL button handler
                    //The user has clicked the cell, so bring up the dialog.
                    button.setBackground(currentColor);
                    colorChooser.setColor(currentColor);
                    button.addFocusListener(new FocusListener() {
                        @Override
                        public void focusLost(FocusEvent e) {}
                        @Override
                        public void focusGained(FocusEvent e) {
                            // dialog closed and focus restored
                            button.removeFocusListener(this);
                            fireEditingStopped();
                    dialog.setVisible(true);but a simpler request might be better (althoug I still need an invoke later):
    // rest as before except the FocusListener
                    dialog.setVisible(true);
                    button.requestFocusInWindow();
                    EventQueue.invokeLater(new Runnable() {
                        public void run() {
                            fireEditingStopped();
                    });And a quick fix to the renderer so you can actualy see the focus on it:
                    if(hasFocus) {
                        Border border = DefaultLookup.getBorder(this, ui, "Table.focusCellHighlightBorder");
                        setBorder(BorderFactory.createCompoundBorder(
                                border, BorderFactory.createMatteBorder(1, 4, 1, 4,
                                        ((MatteBorder) getBorder()).getMatteColor())));
                    }
