APEX_ITEM. DISPLAY_AND_SAVE change in CSS question

• Two quick questions (hopefully) - right way to dynamically change the CSS class and put of Splash screen implemented

  Couple of quick questions have left me speechless!

  So, it seems obvious that many JavaFX applications want to dynamically change the CSS styles.  Is the best way to do it through la.getStyleClass () .add ("classname") < node >?  The underlying data structure is a list of observable.  So let's say we have 5 styles that simply to change the fill color of a circle of 5 different colors, respectively.  So if I have a condition in which I want to dynamically apply 1 of these 5 styles, as I do now it's by setting all 5 styles as a string in a list by using a static initializer, then I call < node > .getStyleClass () .removeAll (list), then getStyleClass () .add ("classname").  I do this to avoid adding again and still the same style and inflate the underlying list.  What is the right way to manage dynamic CSS styles?

  Finally a very simple I think.  So I know there's a little differently to implement a splash screen.  My app has certainly got bigger in the last few months of development and I noticed there are about a 5 second delay between when I run the application when I see the main stage.  I was thinking what a splash screen would be nice to fill that time.  I had no time to prototype using a Preloader and I fear that using another, early stage start-up again would be too long of a delay.  "I actually thought that using the Nice and simple JVM argument" - splash: image name > "would be simple, easy and effective.  Unfortunately when I try to do, the splash screen appears but never goes away.  Anyone know what is happening with this?

  Your mechanism to manage the css style classes is a good approach; I've used several times. I wonder why the style classes have been implemented as a list, instead of a game, but there may be cases of good use for the use of a list.

  In some cases you can also consider using CSS PsuedoClasses, which were presented in JavaFX 8. Here is a little easier to use, especially if you have two options. But a use case might look like:

  public class Message {
      public enum Status { NORMAL, WARNING, CRITICAL }
  
      private final ObjectProperty status = new SimpleObjectProperty<>(Status.NORMAL);
      private final StringProperty message = new SimpleStringProperty();
  
      // constructor, getters, setters, and property accessors....
  }
  

  public Label createLabel(Message message) {
      PseudoClass warning = PseudoClass.getPseudoClass("warning");
      PseudoClass critical = PseudoClass.getPseudoClass("critical");
  
      Label label = new Label();
      label.textProperty().bind(message.messageProperty());
      message.statusProperty().addListener((obs, oldStatus, newStatus) -> {
          label.pseudoClassStateChanged(warning, newStatus == Message.Status.WARNING);
          label.pseudoClassStateChanged(critical, newStatus == Message.Status.CRITICAL);
      }
      return label ;
  }
  

  And then your css looks like

  .label:warning {
      -fx-text-fill: orange ;
  }
  .label:critical {
      -fx-text-fill: red ;
  }
  

• How to fix: Page Template styles do not respond to changes in CSS files in the text editor of 'Developing' Admin Console

  I bought a model site.  It has a css file, /styles/screen.css

  It also has a template page 'home' with the link to the style sheet within the < head > section:

  "< link href="/styles/screen.css "rel ="stylesheet"type =" text/css"media ="screen"> < / link >

  I am tempted to change screen.css, by editing the file in the 'Develop' administration Console and pressing the 'Save' button on the file when changes are made.

  However, the changes do not appear in the preview of the Page template.

  However, if I do a < style > section in the head <>of the page template and put the change, it displays correctly.

  It's like the Page template does not recognize changes to the screen.css.

  I press "Save draft" and "Update" before you press 'Preview' to check for changes.

  My question is how to fix the Page Template styles that do not respond to changes in CSS files in the text editor of 'Developing' administration Console.

  I am a new user of BC and I agree it is likely a result of not knowing how the css BC.

  Thanks in advance for any assistance with my issue!

  Hello

  I think that you too complicate the thinking problem that BC is a non-standard way of processing applications to a css file. This looks more like a cache or perhaps a code problem. However, I would be happy to take a look at your code and see if I can remember where is the problem. Try Skype me and screen-sharing and I'll see what I can do. It is probably fixed quickly :-) My ID:s 'noviumdesign '.

• Can JavaScript get value from an apex_item.display_and_save point? How?

  I have a PL/SQL region that displays a table using htp using the data of a query that creates some elements apex_item.text and apex_item.display_and_save.
  
  Excerpt from the query:

  select wil.sort_order
         -- item_nbr
         , apex_item.text(11, wil.item_nbr, 20, 20
           , 'id="itemnbr_'||wil.sort_order||'" name="itemnbr_'||wil.sort_order||'" style="text-align:left; "
             onchange="this.value=this.value.toUpperCase(); confirmItem(this);"
             onFocus="hideItemSearch();" ondblclick="showCustItemList(this);"')   item_nbr
         -- item_desc
         , apex_item.display_and_save(21, wil.item_description, 'item_desc_'||wil.sort_order)          item_description
         -- qty
         , apex_item.text(12,wil.qty, 10, 10
           , 'id="qty_'||wil.sort_order||'" name="qty_'||wil.sort_order||'" style="text-align:right; "
             onFocus="hideItemSearch(); hideSearchResult(); " onChange="updateCollection002(this); verifyQty(this); "
             onBlur="hideAvailability();"')   qty
         -- uom
         , apex_item.display_and_save(22, wil.uom, 'uom_'||wil.sort_order)          uom
         -- put_up_cnt
         , apex_item.text(13,wil.put_up_cnt, 3, 5
           , 'id="pu_cnt_'||wil.sort_order||'" name="pu_cnt_'||wil.sort_order||'" style="text-align:right; "
              onBlur="updateCollection002(this);"')   put_up_cnt
         -- put_up_size
         , apex_item.display_and_save(23,wil.put_up_size, 'pu_size_'||wil.sort_order)   put_up_size
       .
       .
       .

  In a JavaScript function I am just checking that the quantity entered is an integer multiple of the put_up_size.

    function verifyQty( pThis ) {
      var l_ndx = pThis.id.substring( 4 );
      var l_qty = $v( pThis );
      var l_pu_size = $v('pu_size_'+l_ndx)*1;
      var l_pu_cnt = ( l_qty / l_pu_size );
      var l_new_qty = l_pu_size * l_pu_cnt;
      alert("l_qty = "+l_qty+" and l_pu_size = "+l_pu_size);
      if ( l_pu_cnt != l_qty / l_pu_size ) {
        alert( "Auto Qty correction. Qty must be a multiple of Put Up Size. You entered "+l_qty+". Changing to "+l_new_qty );
        $s( 'qty_'+l_ndx, l_new_qty );
      }
    } /* end function verifyQty */

  I tried different fields in the first alert statement and it looks like I can get a value for an item of type text, not an item of type display_and_save.
  
  Can't the JS API to get the value of an element of display_and_save?
  
  Thank you
  
  Gregory

• How an apex_item.display_and_save total column

  I created a tabular presentation dynamically using apex_item.text. My query includes three columns; cash, cheque and credit. My last column in the query is a total column of cash, check and credit added together gives me the total for that line. My request;
  Apex_item.display_and_save(10,id) SELECT id,
  apex_item.display_and_save(11,transaction_date) transaction_date.
  apex_item. Silver Text(12,cash_amt,15,15),
  check the apex_item. Text(13,check_amt,15,15),
  apex_item. Text(14,credit_amt,15,15) credit,
  apex_item.display_and_save (15,
  (cash1_amt + cash2_amt + check_amt + credit_amt)) total
  Deposits
  
  In the form, if I change one of the amounts, is it possible to update the total column without having to submit the page (javascript maybe)?
  I don't know how to reference apex_application.g_fxx (i) in javascript, if that's even possible.
