Scrolling a custom Component (e.g. JPanel) with overridden paint(Graphic g)

Hi.
I’m creating an application for modelling advanced electrical systems in a house. Until now I have focused on the custom canvas using Java2D to draw my model. I can move the model components around, draw lines between them, and so on.
But now I want to implement a JScrollPane to be able to scroll a large model. I’m currently using a custom JPanel with a complete override of the paint(Graphic g) method.
Screen-shot of what I want to scroll:
http://pchome.grm.hia.no/~aalbre99/ScreenShot.png
Just adding my custom JPanel to a JScrollPane will obviously not work, since the paint(Graphic g) method for the JPanel would not be used any more, since the JScrollPane now has to analyze which components inside the container (JPanel) to paint.
So my question is therefore: How do you scroll a custom Component (e.g. JPanel) where the paint(Graphic g) method is totally overridden.
I believe the I have to paint on a JViewport instructing the JScrollPane my self, but how? Or is there another solution to the problem?
Thanks in advance for any suggestions.
Aleksander.

I�m currently using a custom JPanel with a complete override of the paint(Graphic g) method. Althought this isn't your problem, you should be overriding the paintComponent(..) method, not the paint(..) method.
But now I want to implement a JScrollPane to be able to scroll a large model.When you create a custom component to do custom painting then you are responsible for determining the preferredSize of the component. So, you need to override the getPreferredSize(...) method to return the preferredSize of your component. Then scrolling will happen automatically when the component is added to a scrollPane.

Importing a custom component from Flash Catalyst with Assets

I am experimenting with Flash Catalyst to see if it would work well for us to create components for Flash Builder to use. As a test I created a very simple component with a Pie Chart and a button and exported it as a fxpl file. In Flash Builder I created a Flex library project and imported the component to it. When I tried to use the component in a trivial test app it gave me an error, saying 'Could not resolve <graphics:fc_pie> to a component implementation', presumably because it had not put the component files in the right place of the library tree - by default they were put in a folder at the same level as components but with the name of the component, below which it had a components folder and an assets folder. If I move the files in these folders to the corresponding folders under src then it works fine.
The question is, how do I get Flash Builder to do this correctly? I assume I'm missing something obvious but I am a real Flash Builder Novice and this process is about evaluating which tools to use. Sorry if I'm being a numpty. I'm using Flash builder 4.5 and Flash Catalyst CS5.5.
Any help much appreciated.

If you look in the library panel, there should be an entry for your custom component - probably something like CustomComponent1.mxml. Drag this out onto the artboard to create a new instance of the component.
In the case of a custom component, you can't change much on the second instance. If you have something like a text input skin though, you can change the text it is displaying for each instance.
We are working on making this sort of thing easier in the future, so stay tuned

Problem with Screen Painter - Graphical Layout Editor.

Hi Friends,
I have a strange problem with my Graphical Layout Editor. I first had the problem that the alphanumeric Editor gets displayed even the checkbox for Graphical Layout Editor is checked. Then I had gone through sdn forums and found that the <b>eumfcdll.dll</b> was missing.Thanks to sdn forums. When I copied that file into the path specified it worked fine. But the problem is my layout screen is not displayed fully. It is just displayed at the top of the window and only in that region I can drag and drop the elements. Remaining part of the window is uneditable.
what is the problem? Do I need to make any further settings?
Regards,
Raju.

try to re-install GUI patch .
<b>Yeah , its like CNTLALTDEL(restart) , So half of the problems get resolved.</b>

JPanel doesn't paint graphics

Hi ! I've been writing a program that should graph a linear function, the problem is that I'm trying to draw a line in a JPanel but this doesn't work XD...The program has 2 windows. The first one is the windows from where i get data for the function, after having the data I press a button that I want to open a new window and draw the function...
This is the part of the code in the button on the first window that certainly opens a new window
private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
   JFrame frm_grafica = new JFrame("Grafica - B-Rabbit");
   frm_grafica.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
   Grafica graph = new Grafica();
   frm_grafica.getContentPane().add(graph);
   frm_grafica.setSize(250,250);
   frm_grafica.setLocation(this.getLocation().x+this.getWidth()+5, this.getLocation().y);
   frm_grafica.setVisible(true);
}but in the new window [that is located beside the first window] this is the code, that doesn't work...yes maybe there's something i don't do or something that i am passing over..
public class Grafica extends JPanel{
    Grafica(){
        this.setBackground(Color.WHITE);
    protected void PaintComponent(Graphics g){
        super.paint(g);
        g.setColor(Color.BLACK);
        g.drawLine(50,50, 20, 20);
}So Hope someone helps me...

//protected void PaintComponent(Graphics g){
protected void paintComponent(Graphics g){//<-- it's 2.00am, small p
        //super.paint(g);
        super.paintComponent(g);

Custom painting on jpanel with scrollable

i have a jpanel with custom painting. because the painting can be wider than the view of the panel i need to implement scrollbars. i have experimented with implementing scrollable and using scrollpanes but i have no result. i need a hint or a tutorial how this can be done

ok, that was the key. but perhaps you can help me with two other problems:
because i dont know how large my panel ( or my scroll-area) has to be, i need to expand it on demand. i tried setpreferredsize for that reason, but nothing happens. i think this method is only for initializing but doesnt seem to function properly at a later point.
next prop:
when i scroll my custom panting area the jpanel isnt repainted. i have some difficulties finding the right eventlistener so that i can get scrollbar events (repaint after each move)

JPanel won't display my custome component

Hi,
I made a custome component class that in its paint method at this stage is suppose to paint a white rectangle on screen. However the when I add this custome component to my JPanel it doesn't show up. Does anybody have a solution for this?
My code for the custome component is,
public spaceMediaDisplayObject(mediaObject mo){
     x = mo.getSpaceX();
     y = mo.getSpaceY();
     height = mo.getHeight();
     width = mo.getWidth();
     name = mo.getName();
     System.out.println("Constructor");
     this.repaint();
public void paint(Graphics g){
     System.out.println("Draw");
     g.setColor(Color.white);
     g.drawRect(x, y, height, width);
And the fragment of code I am using to try and display in on the panel is as follows,
spaceMediaDisplayObject smdo = new spaceMediaDisplayObject(toDisplay);
     spaceBodyPanel.add(smdo);
Please help if able.

If it's null then you need to set the size of each component explicitly:
JPanel panel = new JPanel(null);
Component customComponent = new CustomComponent();
panel.add(customComponent);
customComponent.setBounds(0, 0, 100, 100); // For exampleA simple layout manager could be used to make the component fill the panel, for example:
JPanel panel = new JPanel(new GridLayout(1, 1));
panel.add(new CustomComponent());Hope this helps.

How do I reuse a custom component in Flash Catalyst?

All-
I'm sure this is easy, I simply can't figure it out. I've created a custom component in Flash Catalyst with two states, open and closed. I'd like to reuse this component in my app with different text assest. How is this done? Duplicating the component isn't available in this version...do I need to recreate the whole thing with different text?
Cheers,

Using Hibernate as a Custom Component

I don’t know whether this question is appropriate in LC context.
Our scenario, We have very complex logic in each of JDBC store/retrieve activity in the process. We would like to move this part into Hibernate based custom component.
We tried with simple Hibernate persistence class but it seems to be LC not loading them.
1) Is this the restriction with LC? (using hibernate as a custom component)
2) What is the appropriate solution?
You help is highly appreciated

Jasmin,
Is your class included in the custom component?
Yes, It is a annotated entity class,
When creating sessionFactory it is not loading the class.
i'm using flowing code block for creating sessionFactory,
factory =
new AnnotationConfiguration().addAnnotatedClass(dao.entity.UserEntity.
class).setProperty(
"hibernate.dialect",m_dialect ).setProperty(
"hibernate.connection.driver_class", m_driverClass).setProperty(
"hibernate.connection.url", m_connectionUrl ).setProperty(
"hibernate.connection.username",m_userName).setProperty(
"hibernate.connection.password", m_password).setProperty(
"hibernate.hbm2ddl.auto", m_hbmTodll ).setProperty(
"current_session_context_class",m_contextClass ).configure(resource).buildSessionFactory();
Is the jar referenced in the class patch section of the component.xml?
Yes , I have tried for this approch too , but class is entity class is not loaded.

FocusOut in a custom component

Hi.
I made a custom component using a Canvas with a TextInput and a Button inside.
I need to make a focusOut event to be called when the focus go out of my custom component, but not be called when the focus change beetween the inputtext and the button inside the canvas.
How can I do that?
Tanks.

After deploying Custom Component BO Analysis Adaptive Server would not Start

Hello all,
I just developed my custom component in Design Studio with SDK and uploaded this component to BI Enterprise 4.1 SP2 Patch 3 server . After that, I tried to restart the Adaptive Processing Server which includes Analysis Service. However, the server would not start and it fails. If I uninstall the component and restart the server, it starts and works smoothly.
I have installed the same components to other BI servers without having any problems.
Do you guys have any idea what could be causing this?
Thanks in advanced.

Zahid,
Check if this line is added to the command line of the server holding the DS Server.
-Djavax.xml.parsers.SAXParserFactory=com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl
I had a similar problem, openned a support ticket and that solved it.

Mxml elements inside custom component

Hi all, i'm a flex newbie but i know AS3, i've encountered a problem during the development of a custom component: my custom component is a panel with some buttons, but i want that anyone can insert mxml elements (especially form elements) inside this panel in this way:
ActionScript Code:
<custom:myDialogBox >
   <mx:Form ...>
        <mx:TextInput ...>
</custom:myDialogBox>
So i created myDialogBox component:
ActionScript Code:
<mx:Panel xmlns:mx="http://www.adobe.com/2006/mxml">
    <mx:Metadata>
             [DefaultProperty("hboxFirstLine")]
        </mx:Metadata>
    <mx:Script>
        <![CDATA[
            import mx.containers.HBox;
            import mx.containers.Panel;
            import mx.controls.Button;
            import mx.controls.Text;
            import mx.core.UIComponent;
        ]]>
    </mx:Script>
    <mx:HBox id="hboxFirstLine" width="100%">
    </mx:HBox>
    <mx:HBox id="hboxSecondLine" width="100%" horizontalAlign="center">
                <mx:Button label="Conferma" />
        <mx:Button label="Annulla" />
    </mx:HBox>
    <mx:ControlBar id="controllBar" horizontalAlign="right">
        <mx:Label id="alertFooter" text="sFooter" />
        </mx:ControlBar>
</mx:Panel>
I expect that the form goes inside hboxFirstLine... but instead i get this error:
Error: In initializer for 'hboxFirstLine': type mx.controls.Form is not assignable to target type mx.containers.HBox.
Any idea?

hboxFirstLine has to be a Form, not an HBox.
Also, if that is all the code of your component, you don't need import statements.
HTH.

How Do I Link to Custom Component States From Scrolling Content Buttons?

Hi there, I'm in need of some help as i've got a deadline to meet within the next few weeks and im stuck!
Basically what I've done is i've made a scrolling content lists, containing about 10 products in each one, my plan was to turn each product into a button so that users could click on that product, and take them to a new page containing more detailed information on that product; when they've finished looking at that product they can click a button to return them to the list they were on previously. However I can't just make a brand new state for each product as there is a limit to 20 states, and I will need around 50 of them.
So, from what i've read I will need to create custom components. the only trouble with doing this is that I can't link to the custom component on a different main timeline state (I dont get the option to link to the states of the custom component).
If i put the image of the detailed product into the scroll panel I am able to link to it, however, it's inside the scrolling content and it just scrolls around and stuff which isn't what I want; as it makes it look messy.
- Basically I just need to link from the buttons in the scrolling list, to a more detailed page for that product. Then be able to return to the list using a button.
If anybody has any input on how to achieve this, please help me out. Starting to panic now as this needs to be finished before september :s
Btw i'm happy to share my .fxp file it that helps.
Thanks alot, Hoping for some helpful replies on this topic
- Tom

Hi Tom,
Adding this back here to share my wireframe with the community.
Have put a quick .fxp together based on the 'product' section of your project.
Take a look at how the product lists are linking into the product detail pages within their custom components.
Using this model you should be able to expand out to infinite product detail states. If a particular product area has more than the maximum allowed states, just start a new custom component (part 2 for that product section).
Let me know if you have any questions. Hope this sets you on a path to getting your project complete. It's looking nice.

Scroll bar, buttons and a Custom Component - help

Thanks to another forum I was able to create a scroll panel and add a scroll bar to it. That works fine. Inside the scroll panel I have thumbnails of the product that I'm highlighting. I want to be able to click on the thumbnail and have a full size photo of the product come up in the window next to the scroll panel. I created a custom component that has a stage showing each full size product individually. This worked fine when I simply had buttons and no scroll bar. I could convert the thumbnail to a button and then add interaction so that it would go to the proper state of the custom component. Where I'm having problems is now that I've imbedded the buttons in a scroll panel I'm no longer given the custom component as an option to pick from. I can add interaction, but it only gives me the option of picking one of the pages, and not a component.
I've attached a screen grab to help show what I'm describing.
Any ideas?
Doug

Doug, thanks for asking this question.
Hi ADAM...
It seems that a lot of us are asking the same question: Scrollbar Navigation-Make Actionable
(I created a low-fidelity proof-of-concept to test—using a datalist as you suggested. See link in my posting).
I have reviewed the video you refer to here, but you example still does not allow for individual items in the datalist (scrollbar) to be assigned individual actionable events.
Can you expain your thinking in Option 1, as a workaround? Do you have any other suggestions?
BOTTOM LINE
We are all looking to do the same thing... something we are going to see A LOT MORE of after Uncle Steve's TABLET presentation next week:
A scrolling menu, with selected items in the menu causing "navigation" to a certain point in a scroll panel. (imitating the flick or slide effect of iPhone).
Suggestion: Can you add a field to thedatalist so that when the "repeated item" (in edit mode) is configuredto do an action (i.e., On-Click, Transition to State), we can then assign the state you'd like for each item in thetable itself?
Now the issue is making it change the "State" within another component (i.e. scrolling panel). Can that be done?
Thanks,
- Rick

Problem with inputText in my custom component

Hi, I have a custom dataTable component that I'm trying to get to work. It has to be a custom component because dataTable doesn't support rowspan, colspan, multi line headers, and a rendered attribute for rows. The problem is, that when I wrap the column tag inside my row tag then the method for the inputText tag never gets called in the UPDATE_MODEL_VALUES phase.
I'm starting to think that JSF doesn't support 2 levels of tags between the inputText and dataTable. I'm hoping that someone can tell me what I have wrong with my components.
Here is the JSP snippet.
<cjsf:rptTable>
     <cjsf:data id="dataTable1" value="#{allAuthUser.tableRows}" var="myTableRow1">
          <cjsf:row>
               <cjsf:col>
                    <h:inputText id="tableTestFld" value="#{myTableRow1.testFld}" size="5" maxlength="5"/>
               </cjsf:col>
          </cjsf:row>
     </cjsf:data>
</cjsf:rptTable>Here is what it renders. It looks to me like everything renders fine. So I'm guessing that there is something in a component that is causing JSF during the life cycle to not be able to process correctly.
<table>
     <tbody>
          <tr>
               <td><input id="tblmaintForm:body:dataTable1_0:tableTestFld" name="tblmaintForm:body:dataTable1_0:tableTestFld" type="text" value="" maxlength="5" size="5"/></td>
          </tr>
          <tr>
               <td><input id="tblmaintForm:body:dataTable1_1:tableTestFld" name="tblmaintForm:body:dataTable1_1:tableTestFld" type="text" value="" maxlength="5" size="5"/></td>
          </tr>
          <tr>
               <td><input id="tblmaintForm:body:dataTable1_2:tableTestFld" name="tblmaintForm:body:dataTable1_2:tableTestFld" type="text" value="" maxlength="5" size="5"/></td>
          </tr>
     </tbody>
</table>Note: If I leave off the row tag it renders the same way except of course the <tr> and </tr> tags are missing. If I do this, then the backing method for the inputText tag is called and everything works fine. Why doesn't it work with the row tag in place?
Here are the components:
public class UIRptTable extends UIComponentBase {
     public UIRptTable() {
          setRendererType("tblmaint.rptTableRenderer");
     public String getFamily() {
          return "javax.faces.Output";

Hi, Ray!
1) I was trying to put a button in the column header (for sorting) and I couldn't get that to work. That involved the >colhdr tag. I got that to work but I don't remember the fix. I'll look it up and reply back with that when I can.Dealing the first part of your trouble, you need NOT a custom component.
I have looked through the implementation of RepeaterRenderer, as you advised me, and found that the multi-header possibility is included in the implementation of dataTable control.
The code below is the part of source of repeater.jsp with only change:
<d:data_repeater>  <h:dataTable>
And it works fine.
<h:dataTable id="table"
binding="#{RepeaterBean.data}"
     rows="5"
value="#{RepeaterBean.customers}"
var="customer">

<h:outputText value="Customer List"/>               <!� First Header row -- >
</f:facet>
<h:column>
<%-- Visible checkbox for selection --%>

You may have a look at HTML source to prove that dataTable is already what you need:
<table id="myform:table">
<thead>
<tr><th colspan="6" scope="colgroup">Customer List</th></tr>
<tr>
<th scope="col"></th>
<th scope="col">Account Id</th>
<th scope="col">Customer Name</th>
<th scope="col">Symbol</th>
<th scope="col">Total Sales</th>
<th scope="col">Commands</th>
</tr>
</thead>
<tbody>
2.) The second trouble is still unsettled as previously. Right now I have different task at my job, and I can�t continue investigation of this problem.
But when you find smth., please let me know. I�ll be very grateful.

Using itemCreationPolicy with a custom component

I'm working on a project where the users need to be able to have a 'filtered' view of one of the edit dialogs. I'm using view states to control which of the input fields show up for each view. The 'save' logic is the same for both states, so I still need to be able to pull data for the inputs even if they are not currently displayed. I tried setting itemCreationPolicy to immediate with no success. Some of the inputs were getting created but the initial values were not being set. The issue seems to be that the input component (an extended version of DropDownList) defers setting the selected value until the commitProperties() method. Since the inpit isn't actually being shown, the commitProperties() method is never getting called and the value is never being set.
Can anyone suggest a workaround for this issue? The only thing I can think of would be to use includeInLayout and visible to show/hide the inputs, but that is going to get really messy since I would have to apply it to every input and the FormItem components that enclose them.

Jasmin,
Is your class included in the custom component?
Yes, It is a annotated entity class,
When creating sessionFactory it is not loading the class.
i'm using flowing code block for creating sessionFactory,
factory =
new AnnotationConfiguration().addAnnotatedClass(dao.entity.UserEntity.
class).setProperty(
"hibernate.dialect",m_dialect ).setProperty(
"hibernate.connection.driver_class", m_driverClass).setProperty(
"hibernate.connection.url", m_connectionUrl ).setProperty(
"hibernate.connection.username",m_userName).setProperty(
"hibernate.connection.password", m_password).setProperty(
"hibernate.hbm2ddl.auto", m_hbmTodll ).setProperty(
"current_session_context_class",m_contextClass ).configure(resource).buildSessionFactory();
Is the jar referenced in the class patch section of the component.xml?
Yes , I have tried for this approch too , but class is entity class is not loaded.
