  Create alerts using Navigator of the form object.
  Set the title and the message you have requested (or set the message on the duration of SET_ALERT_PROPERTY)
  To view your message, create a procedure like that...

  PROCEDURE MSGBOX(pMessage IN VARCHAR2) IS
    vAlert NUMBER;
  BEGIN
    SET_ALERT_PROPERTY('ALERT_NAME',ALERT_MESSAGE_TEXT,pMessage);
    vAlert:=SHOW_ALERT('ALERT_NAME');
  END;
  

  Now in your code, use like that...

  MSGBOX('Your message goes here...');

• Change the background color in TableView selection

  Hi, does anyone know how to change the blue background color of a selected line in a TableView? Thank you in advance.

  If you look at caspian.css, you will see that the background color is affected by - fx-accent. So the best thing to do is to change the value of - fx-focus:

  view .table {-fx-accent: red ;}}

  Although I would advise against the inline styles, you can also do:

  TableView tv = new TableView();
  tv.setStyle ("focus - fx -: Red ;"); ")

• How can I change the background color for the entire model

  I'm trying to change the color of gray background for the blue container. I tried to find the location of this gray background in the CSS, but failed.

  Could someone help me understand what line in the CSS file is responsible for the color of the container?

  Thank you

  Anna

  No worries.

  It seems that the background color is controlled by this tag in your style.css file:

  body #header body #footer {}

  background-color: #343434;

  }

  This can be consulted on line 1523 of this file. Change only the blue that you want and you should be good.

  I hope this helps.

  Hello

  This is the script I use. Note that you must specify the reference of the user interface for the object type:

  var vName = this.somExpression;
  var fieldObj = xfa.resolveNode(vName + ".ui.#choiceList.border.fill.color"); 
  
  fieldObj.value = "255,255,255"; // white
  /* Check the type of object and change the .ui reference:
  
       Date field =      #dateTimeEdit
       Dropdown =      #choiceList
       Checkbox =      #checkButton
       Text field =      #textEdit
       Numeric field =     #numericEdit
  */ 
  
  Also the object has to have a background colour to start with. 
  
  Hope that helps,

• How can I change the background color for my site (newbie question)!

  Hi all

  I am completely new to Dreamweaver and to create my first website. I have a div container with a grey background color but I wanted the background of the body (IE outside that div) to be black. I'm displaying in Internet Explorer.

  I don't know that it's a simple solution - suggestions welcomed.

  The URL is http://www.fractionltd.com

  Thank you!

  David

  Take the ' # ' off the coast of the body... tag you apply a style to an id of the div to the body instead of the tag of the real body. That's why your color is not displayed.

  I read the reference that write it a clickable button with a height fixed and the visual aspect of the button is predefined and cannot be changed and so forth... look herehttp://developer.blackberry.com/cascades/reference/bb__cascades__button.html

  I tried this way to change the theme of the application. But I failed! See more details here http://developer.blackberry.com/cascades/reference/bb__cascades__themesupport.html

  How can I achieve this? Please give me help. Thank you in advance. Please forgive my bad English

  Hello

  Button style is predefined according to me. Dark theme can be activated in the bar - descriptor.xml, but it is applied to the application on a global scale and affect all other controls as well.

  You can use a container with background image instead of a button. Example code:

• How to change the background color of the window?

  I would like to change the background color for all applications to pale gray,

  such as Notepad and IE.

  Anyone have any suggestions on how to do it?
  Thanks in advance for your suggestions

  Right-click on a zone empty of your desktop and choose personalize. When customization of the control panel applet opens, choose the color of the window (on the axis, below the pane). When the pane of the window color and appearance opens, click Advanced appearance settings (lower left corner of the pane).

  Now... with the Windows color and appearance of dialog box open, click on the white space of the Window Active (do not click the text in the window) or choose the command window of the point: in the drop-down list. Choose a color for 1 color:, e.g. Gray. Click apply at the bottom right and wait Windows 7 resets the graphic properties.

  If you now open Notepad, you'll have a gray window active. My IE follows suit, but only on a white page. Web designers in general choose the background image or color they want to view, and you will have to go into the options of the browser to replace those.

• How to change the background color of selection of the selected item in the drop-down box of choice?

  How to change the background color of selection of the selected item in the drop-down box of choice?

  By default, the selection background color like 'blue', but if I want it to be "yellow" for example, how should I do?

  Thank you

  The id is applied by (I think) the skin of the ChoiceBox class. You don't need to define.

  You must apply the css in an external style sheet. You can apply the external style sheet to any parent of the box of your choice, or on-site (the most usual way to do it).

  Example:

  import java.util.ArrayList;
  import java.util.List;
  
  import javafx.application.Application;
  import javafx.scene.Scene;
  import javafx.scene.control.ChoiceBox;
  import javafx.scene.layout.VBox;
  import javafx.stage.Stage;
  
  public class ChoiceBoxTest extends Application {
  
    @Override
    public void start(Stage primaryStage) throws Exception {
      primaryStage.setTitle("Example 2");
  
      final ChoiceBox choiceBox = new ChoiceBox<>();
  
      List tempResult = new ArrayList();
      for (int i = 0; i < 10; i++) {
        tempResult.add("Item " + i);
      }
      choiceBox.getItems().setAll(tempResult);
  
      VBox root = new VBox();
      root.getChildren().add(choiceBox);
      final Scene scene = new Scene(root, 300, 250);
      scene.getStylesheets().add("choiceBox.css");
      primaryStage.setScene(scene);
      primaryStage.show();
    }
  
    public static void main(String[] args) {
      launch(args);
    }
  
  }
  

  choiceBox.css:

  @CHARSET "UTF-8";
  #choice-box-menu-item:focused  {
   -fx-background-color: yellow ;
  }
  #choice-box-menu-item .label {
   -fx-text-fill: black ;
  }
