Show and hide columns.

I have a rather large JTable with a lot of columns that are updated once in a while.
Is there an easy way to show and hide columns, so that I don't have to keep track on which a shown and hide when I use setValueAt()...?

JTable does the conversion between the column indexes of the view and the model.
You should be able to add remove columns using addColumn and removeColumn methods. and in the TableColumn class you can specify the coulmn in the model that the TableColumn refers to.

Iframes show and hide

Hi All,
I have the Requirement like :
I have two iframes side by side in a page, and two buttons show and hide,
once i click hide button second iframe should disappear and first one should be increase in size to fit whole window. and once i click show first and second should be 50/50 in the page
for this i followed below steps
1) created page.
2) created two report region (No Template)
3) In one region source i called iframe like
TABLE>
<TR>
<td>
<IFRAME SRC="http://Localhost:7777/pls/apex/f?p=&APP_ID.:&P104_INTERFACE.:&SESSION." WIDTH=&P104_WIDTH. HEIGHT=540 scrolling="auto" frameborder="1"></IFRAME>
</td>
</tr>
</table>
4) in second region
TABLE>
<TR>
<td>
<IFRAME SRC="www.google.com ; HEIGHT=540 scrolling="auto" frameborder="1"></IFRAME>
</td>
</tr>
</table>
6)conditionally showing the region with the help of SHOW and HIDE BUTTON
7)and also on Show and hide button i am setting the value of P104_WIDTH . So the size will vary with conditional display?
NOW MY QUESTION IS:
once i click hide button THE CONTENTS(item VALUES) OF THE FIRST FRAME ARE REFRESHED, DUE THAT ALL ENTERED DATA WIL DISAPPEAR SO HOW TO AVOID IT , without refreshing the frist frame i need to set the P104_width value so it interm width will set in the iframe region??????
Thanks & Regards

I had another idea that I am pursuing. I am looking into extending the current renderer CommandNavigationRenderer and will render another goLink just after the current goLink that will execute a close action. I was able to re-direct the rendering by added an override render-kit block in my current faces-config.xml file.
<render-kit>
<renderer>
<component-family>org.apache.myfaces.trinidad.Command</component-family>
<renderer-type>oracle.adf.rich.NavigationItem</renderer-type>
<renderer-class>com.riscs.ui.backing.jsp.components.ClosableCommandNavigationItemRenderer</renderer-class>
</renderer>
</render-kit>
If this works I am planning on extending the commandNavigationItem by creating a ClosableCommandNavigation tag and add a "closeAction" tag that will determine if a close item should render.
Preliminary work looks promising. I will update if I make progress...please let me know if I am crazy.
Thanks.

Show and hide Lov icons and Date Picker image on conditional?

How to show and hide Lov icons and Date Picker image on conditional?

Why do you just want to make the icons conditional? Shouldn't the field also be conditional?

Hi Ananth,
I tried the same code from that tutorial,its working fine.
once again check the name of the nodes and the elements.
you can try another way also to show and hide input fields.
create one attibute of type WDY_BOOLEAN and bind this attribute to the visible property of the input fields.
for example
attibute name = 'visible ' : type = wdy_boolean :default value = X
onaction of the radio button place the following code.it really works
DATA lo_el_context TYPE REF TO if_wd_context_element.
DATA ls_context TYPE wd_this->element_context.
DATA lv_visible TYPE wd_this->element_context-visible.
DATA lo_nd_radio_node1   TYPE REF TO if_wd_context_node.
DATA lo_el_radio_node1   TYPE REF TO if_wd_context_element.
DATA lw_index            TYPE i.
DATA lo_el_radio_node1_1 TYPE REF TO if_wd_context_element.
lo_nd_radio_node1 = wd_context->get_child_node( name = wd_this->wdctx_radio_node1 ).
lo_el_context = wd_context->get_element( ).
CALL METHOD lo_nd_radio_node1->get_lead_selection_index
    RECEIVING
      index = lw_index.
lo_el_radio_node1_1 = wd_context->get_element( ).
IF lw_index = 1.
    lo_el_context->set_attribute(
name = `VISIBLE`
value = 'X' ).
ELSE.
    lo_el_context->set_attribute(
name = `VISIBLE`
value = ' ' ).
ENDIF.

SetVisible against show and hide

Hello, making some practises I have observed that setVisible method doesn't just makes visible or not, it affects me when I change location of components I have played with setVisible, but when I use deprecated methods hide and show I haven't that problem.
What else makes setVisible than make visible or not?

Hello, the way I see it, setVisible is just a nicer way of setting visibility than show() and hide(). Anyway, the way setVisible is implemented in the Component class is :
public void setVisible(boolean b) {
      show(b);
}So I don't believe you should be experiencing any difference between show() and setVisible(). As to the change in positions of components, you might find the actual implementation useful:
    public void show(boolean b) {
        if (b) {
            show();
        } else {
            hide();
    public void show() {
        if (!visible) {
            synchronized (getTreeLock()) {
                visible = true;
                ComponentPeer peer = this.peer;
                if (peer != null) {
                    peer.show();
                    createHierarchyEvents(HierarchyEvent.HIERARCHY_CHANGED,
                                          this, parent,
                                          HierarchyEvent.SHOWING_CHANGED,
                                          Toolkit.enabledOnToolkit(AWTEvent.HIERARCHY_EVENT_MASK));
                    if (peer instanceof LightweightPeer) {
                        repaint();
                    updateCursorImmediately();
                if (componentListener != null ||
                    (eventMask & AWTEvent.COMPONENT_EVENT_MASK) != 0 ||
                    Toolkit.enabledOnToolkit(AWTEvent.COMPONENT_EVENT_MASK)) {
                    ComponentEvent e = new ComponentEvent(this,
                                                          ComponentEvent.COMPONENT_SHOWN);
                    Toolkit.getEventQueue().postEvent(e);
            Container parent = this.parent;
            if (parent != null) {
                parent.invalidate();
    }I left out the hide() code, since it is quite similar. Anyway, if you are interested in this code you can always look it up - it's avaliable.
Hope this helped, laginimaineb.

Showing of hide columns in JTable.

Hi,
In my Application,The requirement is the user can remove some columns.After that the user can select the columns that he required from the list of all columns.
The user can select already removed column.How can I show the already removed columns?
I am removing columns like this.
int [] col = table.getColumnModel().getSelectedColumns();
table.getColumnModel().removeColumn(table.getColumnModel().getColumn(col[0]));
Please help me getting removed columns.I have to show the columns from the list the user has selected.
Thanks in Advance.
Vattikuti

Hi,
Save your column somewhere before remove it (with table.getColumnModel().getColumn(int) ). And when the user want to show the hidden column, add it to the table with table.getColumnModel().addColumn(TableColumn).
Hope it help you.

Show and Hide Actions Not Working

I'm working on a project that involves showing and hiding objects. I inserted a button and in the Action block for the object, I selected 'Show', then selected the object I wanted to be shown on click. When I preview that screen in the project and select the button to show the object, it shows the object, but then advances the project to the next screen. The only way I've found to combat this apparent flaw is to use an advanced action for what should be a really simple interaction. Also, I have the timing set for all objects on the screen in question to Display for the rest of the slide. Is anyone else experiencing this issue?

Have a look at: Why choose Standard over Simple action? - Captivate blog
As Rick points out, Captivate has always worked that way. And since you are talking about Hide/Show, very often you'll want to hide a group before showing one object. If you are using Captivate 7/8 I recommend to create a shared action for that purpose that you can use over and over again in that project and in other projects.
Dare to Share - part 1 - Captivate blog
Reuse Shared Actions in other Projects - Captivate 7 vs. 8 - Captivate blog

JFileChooser show and hide

I am using a jFileChooser to save a file in a selected location and then I use a check if the file exist to prompt an overwrite option dialog box. I do this like so....
fileChooser.showSaveDialog(jPanel1);
File file = new File(fileChooser.getCurrentDirectory()+"/"+fileChooser.getName(fileChooser.getSelectedFile()) + ".jpg");
filename = file.getPath();
if (new File(filename).exists()) {
        int n = JOptionPane.showConfirmDialog(this,
        "Do you want to overwrite?", "File Overwrite",
        JOptionPane.YES_NO_CANCEL_OPTION, JOptionPane.QUESTION_MESSAGE);
        if (n == JOptionPane.NO_OPTION)
                showme(flag);
}The question I have is, Upon entering a filename and location in the file chooser and clicking the save button the filechooser goes away, if that file already exist the JOptionPane shows and a choice can be made, I want the JOptionPane to prompt over top of the file chooser. Right now when clicking save the fileChooser goes away, then an overwrite option can be made, if it is no the savedialog reappears, Does anyone know how to keep the filechooser shown until a file save of a non-existing file is chosen or a no overwrite option i sshown.
BASICALLY: Does anyone know how to keep the filechooser component shown even when a optionPane component is shown? I don't want it to show and reshow.

Xcode-Show and Hide windows with checkbox?

I am making an applescript/cocoa application in Xcode 4.6. I in my Main Window, I have two windows that are hidden at launch ("Preferances", and "Advanced") and one window ("Simple") that is visible at launch. In the preferances window, I have a checkbox. I would like that box, when checked to display the "Simple" window, and Hide the "Advanced" window, and even when closed and relaunched, will remain how the preferances are, and not have to check the box everytime on startup of the app. Anyone know how to do this? Thanks!

Ok something isn't quit right
I in my Main Window, I have two windows that are hidden at launch ("Preferances", and "Advanced") and one window ("Simple") that is visible at launch. In the preferances window, I have a checkbox. I would like that box, when checked to display the "Simple" window, and Hide the "Advanced" window,
What do you mean by in the main window are two windows? Also if the checkbox is in the preferences window and that is hidden at launch how do you get to it to check/uncheck it?
This checkbox basically toggles between the two windows? selected it displays the 'simple' window, when unchecked it displays the "Advanced" window?
This script
script AppDelegate
property parent : class "NSObject"
    property ppw : missing value
    property isShowing : 0
          on applicationWillFinishLaunching_(aNotification)
-- Insert code here to initialize your application before any files are opened
          end applicationWillFinishLaunching_
          on applicationShouldTerminate_(sender)
-- Insert code here to do any housekeeping before your application quits
                    return current application's NSTerminateNow
          end applicationShouldTerminate_
    on displayButton_(sender)
        if (isShowing = 0) then
            ppw's orderFront_(sender)
            set isShowing to 1
        else
            ppw's orderOut_(sender)
            set isShowing to 0
        end
    end
end script
will toggle a second window from a button on the firsst window.
This is what the nib file looks like
ppw is attached to the panel.
This should get you started. Post back if you have more questions.

Mail and Smart Folders losing column show and hide settings - a fix?

Lately I switched my mail to be hosted by google and so in order for my in and out boxes to contain my current and older messages, I have each set as Smart Folders. It's this difference that I think might be making this bug worse.
Previous to this change I'd noticed Mail forgets which columns I have shown and what order they're in between quitting and relaunching.. but now with the smart folders, the column settings will be lost when I'm merely not paying attention to Mail (when it's hidden or in the background).
This is particularly irritating since I always use Mail with two view windows, one showing my inbox and the other showing my sent messages. What seems to be happening most is that if I have my inbox showing From and To, that setting will bleed over to the sent window.. showing me that all my sent messages are, of course, From me. I hide that column and later on it comes back by itself. Either that, or I hide the From column in Sent and later on I lose the From column in the Inbox.

Hobyx,
Wow this thread really is a little stale. Sorry about that. What it sounds like to me is the preferences file is going bad, you could try removing com.apple.mail.plist. Found in Macintosh HD -> Users -> YOUR USERS -> Library -> Preferences. Please note that you will have to add your Gmail account back in. But any emails/smart folders on your Mac wont be removed by deleting that plist.
Also On the Gmail side you will get significant better results if you select the corresponding folder in your gmail account 'Found in the sidebar' and select Mailbox -> Use this Mailbox for -> and select what your using for. Whilst using the imap setup.
Hope that helps,
Weston

Dynamically show and hide detail columns according to master column value

i want to create a page where 2 level master detail.
that is main master region with search option for query (query region)
2nd detail with table
and 3rd detail. (1-2-3)
Here in 3rd detail region, some fields should be shown and some fields hide according to the value of one filed in 2nd detail table(for the current selected row).
please advice
or
please point me to any similar posts

Zam,
show/hide is only beneficial if its optioanl for user to hide or show the fields at your detail region.If it is not , you will have to use PPR and transient VO approach.

Show and hide events in a dashboard widget

These two functions never seem to fire off. If the widget is hidden the hide function doesnt run and the show function only runs on the insitial load.
My problem here is that i am running a setinterval to perform a task every 30 seconds while visible and when the dashboard closes and the widget is hidden the timer still runs. I'd like it to stop and only start again when the widget shows, any ideas?

I would use visible and includeInLayout properties

How to make a button show AND hide a field?

In an interactive form (with Adobe Acrobat X Pro), how can I purpose one button to:
1.) Show a field when clicked the first time
2.) Hide a field when clicked a second time
I seem to only be able to make a button do one or the other, but not both with the same button. Maybe an easier way to say this is I want to be able to have one button turn a field "on" and "off".
Any help would be GREATLY appreciated. Thanks!

Use this code:
var f = this.getField("OtherFieldName");
if (f.display==display.visible) f.display = display.hidden;
else f.display=display.visible;

How to show and hide plots which are stacked and plotted on the one graph?

I am currently designing a Logic Analyser with 8 channels. These are plotted on a graph, stacked on top of each other. The user is able to select which plots he/she wishes to examine (i.e 1,4,6). I need to figure out how to hide the plots not required and show the plots needed.

Hi,
Did u say stacked?? then you must be using a chart not a graph
Nevertheless, as Unclebump has suggested, here is a Vi to give you an idea on how to use active plot and visible property nodes
Build on it to hide/show plots
Regards
