How can I dynamicly add control elements to a form

Hello,
I want to dynamicly add elements to a JPanel.
The elements with the properties are stored in a database
each record contains one element
Label
Combobox
Checkbox
I`m programming in NetBeans 5.5
Something like:
public void test()
try
stmt = GeneralDBConnect.createStatement();
ResultSet rs = stmt.executeQuery("select device_option_id, objecttype, device_option, size, location, tooltip from device_option where ...");
int i = 0;
if(rs.next())
i = i + 1;
switch(rs.getString(2))
case "Label" : JLabel Element[i] = new JLabel();
Element.setText(rs.getString(3));
break;
case "Textbox" : JTextField Element[i] = new JTextField();
break;
case "Combobox" : JComboBox Element[i] = new JCombobox();
Element[i].setToolTipText(rs.getString(6));
ResultSet List = stmt.executeQuery("select device_option_value_id, option_value from device_option_value where ...");
while(List.next)
Element[i].addItem(List.getString(2));
List.close();
break;
case "Checkbox" : JCheckBox Element[i] = new JCheckBox();
break;
jPanel_Device_Option.add(Element[i])
rs.close();
stmt.close();
catch (SQLException ex)
ex.printStackTrace();
I know the Element[i] is wrong code but I need to give the elements an unique name.
Can anyone assist me in this matter

Hello everybody,
I figured it out. I had to change the layout model of the JPanel.
I`ve chosen to use the gridbaglayout because its very flexibel. See http://java.sun.com/docs/books/tutorial/uiswing/layout/gridbag.html
Here is my code:
Description:
Whenever an item in a Combobox is changed (representing devices) the optional elements (a collection of Textfields, checkboxes, comboboxes) are shown in a JPanel.
Which Elements are shown is stored in a database. (Tabels device, device_option and device_option_value (stores the JCombobox items))
First create a JPanel in the graphical editor and right click it choose set layout\gridbaglayout
        jPanel_Device_Option.setLayout(new java.awt.GridBagLayout());
        jPanel_Device_Option.setBorder(javax.swing.BorderFactory.createTitledBorder("Device Options"));
        jPanel_Device_Option.setAutoscrolls(true);Then to create an empty border so the elements don`t clip to the edge of the JPanel add the following code in the properties window in the code section under node "Post-Init code"
        Border bBorder = jPanel_Device_Option.getBorder();
        Border bMargin = new EmptyBorder(0,10,0,10);
        jPanel_Device_Option.setBorder(new CompoundBorder(bBorder, bMargin));Then declare the public variables at the beginning of the code
    public static ArrayList aDatasetElements;
    public static JLabel[] aLabel;
    public static JLabel[] aTextfieldLabel;
    public static JTextField[] aTextfield;
    public static JLabel[] aComboboxLabel;
    public static JComboBox[] aCombobox;
    public static JLabel[] aCheckboxLabel;
    public static JCheckBox[] aCheckbox;And now the method that`s creating the elements
public void setOutputSettings()
      jPanel_Device_Option.removeAll();//Clear all existing elements from the JPanel
      jPanel_Device_Option.repaint();//Refresh the JPanel
      if(jComboBox_Output.getSelectedItem().toString().length() > 0)//Check if any elements should be added
          GridBagConstraints gbConstraint = new GridBagConstraints();//Create a new gridbagcontraint (properties of layout) check http://java.sun.com/docs/books/tutorial/uiswing/layout/gridbag.html
          gbConstraint.fill = GridBagConstraints.HORIZONTAL;
          gbConstraint.anchor = GridBagConstraints.PAGE_START;
          gbConstraint.weightx = 0.5;
          try
              stmt = GeneralDBConnect.createStatement();
              /*Collect data from the database (Which elements should be displayed)
                  deviceoption: The name of the option this is displayed in the elements label as text
                  tooltip: Show a tooltip on both label and element
                  device_optio_id: gets the ID needed to get the list values for a combobox also easy to use when getting the data afterwards (stored in a public variable

              ResultSet rsElements = stmt.executeQuery("select device_option, tooltip, device_option_id, objecttype from device_option where deviceid = (select device_id from device where devicename = \'" + jComboBox_Output.getSelectedItem() + "\') order by sequence_order asc");
              aDatasetElements = new ArrayList(); // Makes an array
              while(rsElements.next()) //get data in arraylist (a resultset closes after a while (garbitch collector) resulting in errors I recieved some errors resulset allready closed. Also needed to acces data afterwards
                  aDatasetElements.add(new String(rsElements.getString(1)) + " ;" + new String(rsElements.getString(2)) + ";" + new Integer(rsElements.getInt(3)) + ";" + new String(rsElements.getString(4)));
              rsElements.close();
              aLabel = new JLabel[aDatasetElements.size()];          //Makes an array

I hope ths is helpfull information.
Since I`m totally new to Java it is possible that a different approach is better however this is working for me.
I`m open for any remarks on the code and feel free to give any comments.

Add HTML element

Hey there!
I was wondering if there is a way to add specific HTML elements to a numbers document. In my case that would be the price-element from an Amazon product page which i would like to always be updated when i open my document. i found the element itself by using the webelements option under the developer menu in safari. I just did not find a way to add it as an updating element!
Thanks in advance!

In the first versions of Pages, there was an export to HTML feature but as far as I know there never was the asked one.
As Apple engineers understood that generating HTML code wasn't their cup of tea, they dropped the feature so I doubt that HTML will be back in any way in the app.

Dynamically add some elements in WebService operation request

Hi,
I have a WebService element defined in my mxml which use to make soap calls.
I need to dynamically add some repeating groups for action (dependent on action) in the following example.
How can I add this in Action Script section? Can I access the WebService by id userRequest and specify "
userRequest.operations.DoAction.request.DoItemActionRequest.action.requiresAdditionItems.n ameValuePair.name = "SomeName";
userRequest.operations.DoAction.request.DoItemActionRequest.action.requiresAdditionItems.n ameValuePair.name = "SomeValue";
<mx:WebService id="userRequest" wsdl="{Application.application.wsdl}" >
     <mx:operation name="DoAction" resultFormat="object"
      fault="faultHandler(event)"
      result="DoActionHandler(evnt)">
        <mx:request>
          <DoActionRequest>
             <userId>{Application.application.userID}</userId>
              <action>
                 <actionId>{selectedItem.actionId}</actionId>
             </action>
          </DoActionRequest>
         </mx:request>
       </mx:operation>
</mx:WebService>
Thanks,
Amitava

Hi miguel8312,
Thanks for your suggestion. I understand the steps you explained for defining, calling and processing the result from a webservice from a MXML body.
My query is specifically, can I modify the webservice request defination from AS function before making the call?
In my example, if I need to dynamically add a name value pair for <action> tag (e.g. actionParam ), how do I do that?
Thanks,
Amitava

Add subscript in Dreamweaver code screen

In Dreamweaver - How do you add HTML elements to the favorites insert menu that are not on the list? For example, I want to add <sub> and <sup> so I can highlight and code math equations>
Thanks

It's a lot more convenient than using what I posted initially, with Snippets...
1. Select some random text
2. In the Snippets panel, click the +
3. Name it Subscript
4. In the Insert Before field, add <sub>
5. In the Insert After, add the closing </sub>
6. Hit OK and do the same for <sup>
7. Go to Edit > Keyboard Shortcuts
8. under Commands, choose Snippets from the dropdown
9. Click the folder you created the Sub and Sup snippets in
10. Highlight the Sup snippet, click in the Press Key field and hit the desired keyboard shortcut
Once you give them both a shortcut you like, from there on out, you just highlight the text and hit that keyboard command to add the <sup> or <sub> tags around the text.

How to add screen elements at run time on button click in Web Dynpro abap?

Hello All,
I have a requirement wherein the user wants to add the textbox dynamically at runtime on button click action. My questions is, Is it feasible to dynamically add screen elements at runtime? If yes, how?
Please help.
Thanks

Hi Ajinkya,
This is absolutely possible! Adding view elements at runtime is called "dynamic programming". There are a lot of good resources and tutorials on SCN if you do a search. To start you off, here is an excellent series by Thomas Szücs:
Dynamic Programming in Web Dynpro ABAP - Introduction and Part I: Understanding UI Elements
Dynamic Programming in Web Dynpro ABAP - Part II: Handling ViewElements
Dynamic Programming in Web Dynpro ABAP - Part III: Aggregations and DDIC-Binding of ViewElements
Another option that avoids dynamic programming is to create the view element at design time but bind its visible property to a context attribute of type WDUI_VISIBILITY. You could initially set its visibility to "none" until the user clicks the button, then you could change its visibility to "visible".
Cheers,
Amy

Is it possible to add HTML Code in Tooltip WDA UI Elements?

Hi All,
I had a thought which i was not sure how to implement.
Scenario:
When user roles over a Field in the table, I want the details of that record appearing in the Tooltip. Physicall via the framework, I am not able to do so as tooltip is only bindable to Text. I was wondering if there is possibility where we could display some simple HTML pages, upon role over a UI element.
Please let me know if you have an idea how to get this done.
Thank you.
Regards,
Vinod

No. There is no rich tooltip in Web Dynpro. It is a plain text tooltip only. Any HTML or JavaScript code that you would insert would be safe encoded and displayed as part of the tooltip instead of being used as markup or executed.

Dynamically add Children Link Element

Hi,
I'm trying to dynamically add a children element, a link, but the action binding refuses to work ...
I've created a custom jsf component, that does nothing at all.
For example, one would use it like:
<my:nothing></my:nothing>So my UI class would have the following methods:
public void encodeBegin(FacesContext context) throws IOException {
public void encodeEnd(FacesContext context) throws IOException {
}The tld file is created, the tag class is working. All the component is working properly.
Now I want to add a link as a child component, but I wat to do it programatically, so I changed the encodeBegin method of my custom ui class:
import javax.faces.el.ValueBinding;
import com.sun.faces.util.Util;
import javax.faces.el.MethodBinding;
import javax.faces.component.UICommand;
import javax.faces.component.html.HtmlCommandLink;
import com.sun.faces.taglib.html_basic.CommandLinkTag;
public void encodeBegin(FacesContext context) throws IOException {
          String myLinkId = "idMyLink";
          String myLinkValue = "myLink:Value";
          String myLinkStyle = "color:green;";
          String myLinkAction = "backup";
          HtmlCommandLink myLink = new HtmlCommandLink();
          myLink.setParent(this);
          myLink.setId( myLinkId );
          if (CommandLinkTag.isValueReference( myLinkValue )) {
               ValueBinding vb = Util.getValueBinding( myLinkValue );
               myLink.setValueBinding("value", vb);
          } else {
               myLink.setValue( myLinkValue );
          if (CommandLinkTag.isValueReference( myLinkStyle )) {
               ValueBinding vb = Util.getValueBinding( myLinkStyle );
               myLink.setValueBinding("style", vb);
          } else {
               myLink.setStyle( myLinkStyle );
          if(myLinkAction!=null) {
               if (CommandLinkTag.isValueReference( myLinkAction )) {
                    System.err.println("Id="+myLinkId+":TRUE:getAccao:isValueReference:"+myLinkAction);
                    MethodBinding vb = getFacesContext().getApplication().createMethodBinding(myLinkAction, null);
                    myLink.setAction(vb);
               } else {
                    System.err.println("Id="+myLinkId+":FALSE:getAccao:isValueReference:"+myLinkAction);
                    final String outcome = cNfo.getAccao();
                    MethodBinding vb = Util.createConstantMethodBinding( myLinkAction );
                    myLink.setAction(vb);
          myLink.encodeBegin(getFacesContext());
          myLink.encodeEnd(getFacesContext());
}This seems to work, but not quite ... the link appears as expected, the value references for value and style are correctly passed, but the action doesn't work at all.
For example if I change to:
String myLinkValue = "#{mybean.linkText}";And I have the following method created on my managed bean:
     public String getLinkText() {
          return "This is myLink Text!";
     }Is successfully calls and retrieves the value from the method. Same happens to the style property.
Now for the action, if I change to:
String myLinkAction = "#{mybean.doMyLinkAction}";And I have the following method created on my managed bean:
     public String doMyLinkAction() {
          return "backup";
     }The result is nothing ... I mean the method is not called at all. The "backup" is properly defined on my "faces-config.xml":
   <navigation-rule>
      <from-view-id>/testPage.jsp</from-view-id>
      <navigation-case>
         <from-outcome>yes</from-outcome>
         <to-view-id>/yes.jsp</to-view-id>
      </navigation-case>
      <navigation-case>
         <from-outcome>no</from-outcome>
         <to-view-id>/no.jsp</to-view-id>
      </navigation-case>
      <navigation-case>
         <from-outcome>backup</from-outcome>
         <to-view-id>/backup.jsp</to-view-id>
      </navigation-case>
   </navigation-rule>If I create the link manually on the web page:
<h:commandLink id="myLinkManual" value="Manually Created Link" style="" action="#{mybean.doMyLinkAction}"/>It does work (the backup.jsp page is shown), so the methods are properly configured, only the action binding does not work.
Wether I use a string "backup" or a reference "#{mybean.doMyLinkAction}" I cannot make it work.
On the console I get the following results, for each value I test (string "backup" or reference "#{mybean.doMyLinkAction}"):
Id=idMyLink:TRUE:getAccao:isValueReference:backup
Id=idMyLink:FALSE:getAccao:isValueReference:#{mybean.doMyLinkAction}So the "if (CommandLinkTag.isValueReference( myLinkAction )) {" is working properly ... that just leaves me with the action method binding instructions ...
Why don't they work?
Any Help Appreciated ... Thanks in Advance!

c'mon guys ... can anyone test this and help me out?
Pleeeeeease ... I'm really needing this working out.
Thanks

Is it possible to add html code to iweb

I need to add some special elements to a webpage, and I was curious if I could add any special html code besides the ones I have found in the menu (counter, links, etc)
Thanks

This is iWeb's glaring weakness. I need the ability to add html for blog rolls, haloscan comments on blogs, etc.
Currently, I use RapidWeaver, but the drag and drop design elements in iWeb are far superior. However, the ability to add raw html code is going to hold iWeb back.
Add this, Apple, and you've got a winner.

how do i add html code to my muse site? I want pintrest to verify my site.

Hi,
There are multiple ways in which you can add the HTML code to your site. Few methods are :-
1) Copy your HTML code, In Muse -> Select Objects-> Insert HTML . Paste your HTML code on the page. Please reer to this screenshot :- http://prntscr.com/52vprn
2) If you want to add the HTML code in the Head section of your page, Go to Page Properties-> Metadata-> HTML for <Head> . Please refer to this screenshot :- http://prntscr.com/52vpx5
Hope this helps

Add html code in web dynpro application

Hi
Is there a method to add HTML Code in web dynpro application so that it works same as HTML works in browser
I have to add a clock in my application How can i do that
Best regards
Suresh

If you're on NetWeaver CE or otherwise use Wb Dynpro for Java 7.2 or higher, you could use the WebWidget control, see http://help.sap.com/saphelp_nw73/helpdata/en/49/bfa3b2e55657bae10000000a42189d/frameset.htm
Otherwise, I'm afraid your only option is to use an IWDIframe component in your WDJ project, embedding the HTML.. Be carefulo though, the IWDIframe component is deprecated (since each server roundtrip forced a reload of the IFrame it was pretty useless)
Hope this helps!

thanks in advance..!

Sending HTML text - this is supported by UTL_MAIL. You simply need to format the Mime body correctly. Sample code in {message:id=3914506}.
Sending embedded images are a tad more complex. And not something I would try with UTL_MAIL - UTL_SMTP allows you to define the Mime body yourself, without UTL_MAIL doing that (poorly) for you. The type of Mime body to generate is explained in {message:id=9676442}. Example of using UTL_SMTP to send an multi-part Mime body in {message:id=4593735}.
Another example of a Mime body including a uuencoded image is in posting {message:id=4402801}. See message {message:id=10364104} for how to encode an image into ASCII as an attachment for a Mime body.

<iframe style="height: 270px; width: 450px;" src="http://www.mapquest.com/embed#a/maps/lisneyland:1313+S+Harbor+Blvd:Anaheim:CA:92802:U S:33.8127:-117.9154:address::1/m::12:33.8127:-117.9154:0:::::1:1:1::/io:0:::::f:EN:M:/e" marginwidth="0" marginheight="0" frameborder="0" scrolling="no"></iframe><br/>

Flash only supports a minimum number of html tags and they can only be implemented in textfields using the TextField.htmlText property. "iframe" is not a supported tag.

How can I add an HTML Element to a RowSetBrowser

Hello,
I am looking for any help on adding a HTML element such as a checkbox to every row that is returned to the RowSetBrowser. I am wanting to have the value on the checkbox be the primary key such as a logid, so that I can have a user select multiple rows, and then create a combined log that will be stored in the database as one record.
Could anyone please let me know if you can add an HTML element to the RowSetBrowser.
An answer would be greatly appreciated ASAP. If this cannot be done, I would like to go about it another way.
Thank You,
Jason

The idea is the following:
First you create a new attribute in the ViewObject, with the following information:
In the definition of the new attribute, there are three things to consider:
In the information "Attribute":
- Name: RowChecked
- Type: String
- Selected in Query: Yes
In the information "Updateable":
- Updateable: Never
In the information "Query Column":
- Alias: RowChecked
- Expression: '<input type="radio" name="recomendado" value="'||TableName.ColumName||'">Text to show'
- Queriable: Yes
Then in the jsp page you use the setDisplayAttributes method where you include the attributes to render, to show this attribute you have created. And if you need pass this information to another page, include a a HTML Form before the RowSetBrowser, and after the bean a button to submit the information and finally close the HTML Form.
I hope this information can help you.
