Resize applet within a HTML frame

Hi,
I am using an applet to display a tree in a HTML frame of a web page.
I would like to resize or refresh the applet when the HTML frame is resized. Is there a way for the applet to know when the HTML frame is resized?
Any help will be appreciated.
Thanks

I tried using the componentResized() method to solve this problem but I was unsuccessful.
Here is what I tried:
My application consists of using a Java applet to display a tree in a HTML frame. In addition I put the tree in a scroll pane. I tried using addComponentListener(this) to get the componentResized() method to be involked. I tried adding the component listener to the scroll pane:
JScrollPane treeView = new JScrollPane(tree);
treeView.addComponentListener(this);
I tried adding the component listener to the root pane:
JRootPane root = getRootPane();
root.addComponentListener(this);
and I tried adding the comoponent listener to the glass pane and the content pane.
The componentResized() method was involked when the tree was initially displayed in some of my attempts but I was never able to get the componentResized() method to be involked when I resized the html frame.
I believe that I am having a problem determining which component to add the addComponentListener to so that the componentResized() method get invoked when I resize the html frame.

  • Applet reloading w/ html frames

    My applet is in a navigation bar, in its own html frame. When going to another page, I load a new html frame set. The applet html frame is still the same, the other frames change.
    HTML knows how NOT to reload the html frame that contains the applet, since it's the same as before. But the applet itself will reload everytime. I mean, the applet classes don't load again, but the applet process starts again, going through the init() method.
    I thought it would go to start() directly, which is what I want.
    What should I do?
    Miguel

    Applets need to be initialized when the page is loaded so you can't reliably avoid it. (making a static flag would solve the problem on some browsers so that the code is performed only when the class is loaded, but some browsers do reload the classes every time...)
    Why do you need to load a new frameset? You do know that you can specify the frame where the document will be loaded with the sencond parameter of the showDocument-method....

  • JSP applet tag X Html applet tag (what is the difference?)

    what is the advantage in using the JSP applet tag instead of a simple Html applet tag ?
    second question:
    I have an applet in a Html frame, and a menu on the left side.... When the user select the applet option at first time, everything runs ok.. after the user select another option and then select the applet again, it fails in some features .. Why ?

    well, if by "the JSP applet tag", you mean the jsp:plugin tag.. that will just generate the same HTML tag you would write. The only advantage would be it should be less typing to use the taglib.
    second answer:
    without seeing any code, it'd be hard to figure out the problem. The obvious thing is you are setting some state of something that is preventing further action.

  • Resizing applet

    Hi,
    I have an applet which is quite large, when you run the applet using appletviewer it fills the whole screen, this means when I run the applet in an HTML document it is partly obscured and you have to scroll. I know you can size the applet in HTML but this will obscure it. It means I have to resize the layout in java, which would mean resizing every component etc (there are a few). I would like the applet to open and just fill the bowser screen. Is there an easy way around this.
    cheers
    macnero

    1. Use a layout
    2. Use constants for the frame size
    3. Allow Java to "fit" all of the components in the frame, don't explicitly try to assign sizes of you don't need to do so.

  • Session timeouts for login page with in a html frame

    Hi, i have a login page which when the session times out gets redisplayed within the frame of the html page where the session timed out , i have tried setting the session timeouts to be less than the other application so that the login page will timeout before the documentum application but this does not make a difference.
    does any one know how i could get the login page to redisplay by itself, outside of the html frame. do i need to have some javascript to figure out if there is a frame then redraw the page etc...and how should i di this ? any working examples will be appreciated.

    You would certainly need some Javascript or use the meta-refresh tag to the session timeout time. If you set the meta-refresh tag in a frame to a time just a little bit bigger than the session timeout time and the set your security mechanisms to force the user to login in again when the session times out, the frame will refresh after the session has timed out and the application should forward the frame to the login page.
    <meta http-equiv="refresh" content="session-timeout-timeout+1">
    (timeout time is in seconds)

  • Resize applet - more info

    I want to be more specific: i have a class that extends applet to this class i added two panels. to one of the panels i added 100 buttons, to the other 4 labels.
    i have also a class that extends frame, in order to run my applet as an application. i added to this frame my applet, when i create a new instance of the applet the constructor add's all the panels and buttons.
    In order that when i resize the frame also the applet including all its panels and buttons will be resized, i added to the frame a componentlistener and called setsize in my applet with the appropiriate dimenstion, it seemd to work, but the panels didnt resize, so i overlapped in my applet the setsize method and added pnael.setsize for the two panels but it still doesnt work.What is the right way to do this??

    >

    i added to the frame a componentlistener and called
    setsize in my applet with the appropiriate dimenstion,you don't need a componentlistener - the LayoutManager of the Frame (a BorderLayout) takes care of the resizing of the applet

    pnael.setsize for the two panels but it still doesnt

    I think you should use an GridLayout in the Applet
    for example:
    myApplet.setLayout(new GridLayout(1,2));
    myApplet.add(panel1);
    myApplet.add(panel2);

  • Flash nav targeting html frames...

    I have NO idea why, I've read all the posts about having a
    flash nav menu target a frame within a HTML frameset. I even set up
    a quick test... (I'm using flash MX2004 professional so you all
    know)
    Ok, this is what I did....
    I created a framset in Dreamweaver using their fixed top
    frameset. So there's a top nav frame, and a bottom content frame.
    the frame holding the flash nav is called header.htm. The
    content frame is called main.htm (or the default htm page that
    opens in that frame) The frameset master of course is called
    index.htm.
    I created a test flash nav with 2 quick buttons. This is the
    code on the first and second buttons...
    first button:
    on (release) {
    getURL("test1.htm","mainFrame")
    second button:
    on (release) {
    getURL("test2.htm","mainFrame")
    As you can see I'm targeting the content frame which is named
    "mainFrame" in the index page like this:
    <frameset rows="119,*" cols="*" framespacing="0"
    frameborder="NO" border="0">
    <frame src="header.htm" name="topFrame" scrolling="NO"
    noresize >
    <frame src="main.htm" name="mainFrame">
    </frameset>
    So, I run the whole thing and instead of the flash nav
    pointing at the "mainFrame" frame, it just opens a whole new
    window! I've researched all over the place, and i'm not new to
    flash, i've done some advanced stuff, so you would think this would
    be a simple endeavor... Am I truely that stupid, or is this an
    issue with flash targeting framesets?? PLEASEHELP!!

    Did you heard about _blank , _self , _parent , ....??? maybe
    is something to
    do with the names you are using...
    i didnt understand much ur problem but first thing u have to
    be familiar
    with those things.. i hope that helps.

  • Load applet within another applet?

    Let's say I have two applets, A1, and A2. I'd like to load A1 on my HTML page, and I'd like A1 to load A2 within itself (i.e. not load it as another separate applet on the HTML page).
    Basically, A2 takes some parameters I would like to pass to it through A1, so I'd like to know if this is possible.
    Thanks for any help!
    James

    Totally possible. You just have to provide it an applet context
    see http://java.sun.com/j2se/1.4.2/docs/api/java/applet/AppletContext.html

  • Applet within a table tag.

    Hi,
    I have placed an applet within a <table> tag. The applet does not get executed. I see only blank space, even though the HTML source has the applet tag. If I remove the table tags and place the applet directly in <body>, then it works fine. So there isnt any problem with the codebase or anything.
    Are there any specific rules as to inside which tags can the <applet> tag be embedded? I would apprecite any information regarding this.

  • HTML Frames not using custom scrollbar in Flex 3 mx:HTML

    I've been working on an app that uses a custom skin in Flex 3. The app has a help window. The help contains an HTML with frames. Problem is, the main app vertical scrollbar custom skin is being ignored for the HTML Frames scrollbar (what looks like the classic version of Halo - maybe). This only happens with frames. It happens no matter how or where I place my HTML or HTMLLoader. If I dont have frames the custom scrollbar is used. Is there a node im missing in my skin css (obviously not VScrollBar or ScrollBar - the two standard used by Flex)? or some other way to connect the HTML Frames scrollbar to my custom skin.
    I'm not a noob but not an expert.

  • JSF seems not to support the use of the back buttons and html frames.

    I�m having the following problem. I have a JSP which contains a button that register a listener. Here is part of the code:
    <h:command_hyperlink label="<%=engineBean.getId()%>" commandName="<%=engineBean.getId()%>">
    <f:action_listener type="helloDuke.CommandAction"/>
    </h:command_hyperlink>
    This action listener only forwards the request to other simple JSP.
    The problem appears in the following situation:
    1 � I click in the button that generates the event that will be processed by helloDuke.CommnadAction listener.
    2 � It forward to a second JSP page.
    3 � This second page is rendered to the user properly.
    4 � The user clicks in the browser�s back button to return to previous page.
    Then if is the user clicks in first page button, the CommandAction listener was removed. You must click again in the button to forward to the correct page.
    The same happened if you are using html frames. If you have a frame with 2 pages and both pages register action listeners.
    The last loaded page cleans the actions listener of the other.
    Does anybody have any solution?.
    It seems JSF doesn�t support the use of frames and I think that in some situation the frames are the solution to several problems.
    Any help will be really appreciated.

    Using the saveStateInClient=true produces a faulty output when using the command_button and an action_listener. The page that is rendered is totally useless: the button won't work, and due to the faulty rendering there's an output like: >com.sun.faces.saveStateMarker
    So, why is it, that pressing the button (not using the saveStateInClient option) will only work the second time, same thing pressing the backbutton. Pressing the reload button will toggle between two pages - the one before the session id is assigned and the one that it's supposed to show.
    Any guess will be greatly appreciated !!!!

  • Java Applet in a HTML page: failing with PLS-00306: wrong number of args

    We are trying to use a Java Applet in a HTML page. as our system needs to be able to retrieve a predefined set of data from a third party system that uses Dynamic Data Exchange Protocol (DDE) and are encountering errors from APEX and in IE itself.
    We are using JavaDde from www.nevaobject.com that enables our Java applet to interact with Windows applications (Third Party System) using DDE.
    This functionality is currently used in our Web Form 6i application and we are trying to use the same in the new ApEx application.
    We are using ApEx version : 2.1 and actually aer encountering 2 problems:
    Problem 1: ApEx failing with PLS-00306: wrong number or types of arguments in call to 'ACCEPT'
    Problem 2: IE crashes if Applet used in a complex page with several regions (1 Context, 4 Report Regions, 2 level Tabs, Links)
    This problem does not occur in the page where there is only applet and one region. In the case of complex page the IE crashes if the page is reloaded
    Test scenario:
    1- Create a simple page with the HTML region.
    2- Define the Source of the above region as follows
    <OBJECT CLASSID="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
    CODEBASE="http://java.sun.com/products/plugin/autodl/jinstall-1_4-windows-i586.cab#version=1,4,0,0"

    <PARAM NAME="archive" VALUE="simpleApplet.jar" />
    <PARAM NAME="type" VALUE="application/x-java-applet;version=1.4">
    </OBJECT>
    3- Create a simple Java applet "simpleApplet" - for the test its enough if the applet will have just the init method printing out the mesage to the console
    4- Create a Submit Button (not redirect) in Region Header and create unconditional (do not set When Button Pressed property) Page Branch to navigate to another page (the page without the applet)
    6- Run the page and Submit -
    The error below is returned by the engine:
    In our case our applet is called ddeApplet - I do not know why is ApEx passing the Applet's ID down to the wwv_flow.accept method as a parameter

    "theArrow",
    It looks like whatever HTML you're including on your page is creating HTML input form elements inside the HTML form "wwv_flow". This form is posted to wwv_flow.accept, and of course, the PL/SQL procedure wwv_flow.accept doesn't know anything these additional arguments/form elements you're attempting to POST.
