Handling Buttons

There are multiple buttons (JButton) with the same label on a frame. In the actionlistener how do i recognise which was the button pressed. Please help me out.
regards,
amar

Options
1. Have one listener per button. This makes even more sense if the buttons are unrelated -- why use the same listener
for "find" and "redo"? When doing this, using Action can be a useful for encapsulation.
2. If listening to more than one button, use the ActionEvents getActionCommand to distinguish them. This is the button's
text by default, but you can set this property for the button if needed.

Handling Button Event

Hi all,
i am using a 'When-Validate-item' trigger in this i am doing a validation,
when user try to enter amount greater than the given amount(This is needed validation)
and also i am regenerating new lines(Creating new records when button pressed)
when i am regenerating i should not validate.
How to handle button event
Thnx

Hi...
The WHEN-VALIDATE-ITEM Trigger fires once you updated a field. Be sure you raise
form_trigger_failure when amount is invalid. So, the cursor stays in field amount. You cant
leave this field until the amount is not valid.

Handling button events in large app

I'm currently examining a large swing app, and have observed the following with regard to action events.
A number of listeners (for buttons, menu items, JLists etc.) are defined at the top of the app. These variously extend MouseAdapter or implement ActionListener, depending on the type of component whose actions they listen for.
The ButtonListener definition is as follows :
private class ButtonListener implements ActionListener
public void actionPerformed(ActionEvent event)
Object object = event.getSource();
if (object == button1)
// button1 actions
else
if (object == button2)
// button2 actions
.....etc
One instance of this listener is created in the app, and is used as the actionlistener for each button. This means that the buttonlistener is quite large (as it contains the code for each button in the app).
Is this the proper way to handle button events for an app with a large number of buttons?

Thanks for the responses.
In response to theDude : I agree that defining the action listener for each button can be useful when you can see the button definition and button action in one place; one could counter that by saying that grouping all the button actions makes it easier to examine all button actions in one place.
Setting the action command isn't really an option because the application creates panels of buttons on the fly, e.g. when notification of a new customer is received, a new panel is created with a JTextPane (customer description) and a row of buttons for "Modify", "Delete" and "Print".
Several customer panels could be in existence at the same time, so setting an action command of "Modify" would not enable one to uniquely identify which "Modify" button was pressed.
This problem is currently handled by associating the panel instance with a "Customer" class instance in a hashtable. The "Customer" class consists of a JTextPane field, and a JButton for each function. When a button is pressed, the button listener traverses up the component's parents until it reaches the panel (i.e. it loops until the parent is a key on the hashtable, at which point it can retrieve the Customer instance and check which button was pressed).
In response to KPSeal : If I understand you, I would define "ApplicationAction" separately from the main app and define extensions of it in the main app for each type of action. Would this add much value over merely defining a method for each type of action in the main app and just calling this method when the relevant button/menu item was pressed/selected?
There doesn't seem to be a universal approach to event handling, but I thought there might have been one accepted strategy when an app has large numbers of buttons (some created on the fly, ruling out action commands).

Handling button events for dialog boxes of a used component

Hello,
After I call a dialog box/window for the view of the used component, how can I handle the button events of the window that I called?
I create the window using the method CREATE_WINDOW_FOR_CMP_USAGE of the interface IF_WD_WINDOW_MANAGER. This method returns window reference of type IF_WD_WINDOW.
Thanks & Regards,
Reena

It's very easy.

Best Way to Handle Buttons

I have a complex button graphic that I use for all the
buttons in my Flash project. Currently, for every different button
function I need, I've duplicated the button and linked it to a
separate class. So if I need buttons that link to rules, credits,
playgame, and the main menu, I've got 4 separate button symbols and
4 separate classes.
Is there a better way handle this?
And one other thing. All of my classes are in the "game"
package. I tried putting the buttons in a "game.buttons" package,
but then I could not access the classes in the "game" package, so I
could not go:
(parent as Main).gotoAndStop('Credits");
because it didn't know what "Main" was. (Main is a class in
the "game" package.) What do I need to do to fix this.?
Thank you.

I would create a hidden page item on Page 14 (P14_CALLING_PAGE) and set it via the URL to the appropriate calling page (8 or 12). In other words, when Page 8 navigates to Page 14, it would set P14_CALLING_PAGE to 8 and when Page 12 navigates to Page 14, it would set P14_CALLING_PAGE to 12
Now, you can create your Cancel button with a URL Redirect of &P14_CALLING_PAGE.
This way, when Page 14 is rendered, the Cancel button will be configured to go the appropriate "calling page"
Hope this helps.

[iphone] Handling button touch events

I have a view controller which contains a view which in turn manages 2 subviews that take up the entire scree, think like a playing card, where the 2 subviews simulate the front and back of the same card. When the user taps anywhere on the card, the card flips to show the other side. I have added a button to the card but when I tap within the button, it still triggers the main event to flip the card, not the action associated to the button. How do I make this happen? Thanks

Wups, hit Enter too fast:
Here's what I am doing:
1. Create UIViewController
2. Add a UIVew subclass instance to it. Can override touchesBegan in this object.
3. Add a UIWebView subclass instance to UIView as a subview.
The UIWebView seems to be eating all events silently. I override touchesBegan inside of it, and my printf statement doesn't ever get called, so I am suspecting that touch events are not handled by this class, even though it does inherit from UIView.
Anyone have any ideas?
Thanks!

Click handler button function to control symbols

Hi,
I have a remote control image which has 2 buttons (Slide button & Bar Graph button). Thanks to help from resdesign the first button controlling a slideshow of 15 images works. In the slideshow there are question slides that need to launch an animated bar graph symbol showing the results. I'm able to launch the first bar graph for slide 3. I'm using the container method to place the bar graph on the stage. The bar graph symbol can be closed using a click event from within the symbol.   Here are my questions:
How to toggle the bar graph off OR delete the bar graph symbol when the Bar Graph button is clicked again.
How to prevent multiple instances of the bar graph from launching in the container?
How to close the bar graph if the user advances to the next slide?
Here's the code to control the Bar Graph button on compositionReady:
var bgOn = false;
sym.$("buttonbg").click(function(){
                    if (bgOn == false) {
                    sym.createChildSymbol("bg1", "bargraph_container3");
                    var container = sym.getSymbol("bargraph_container3");
                    sym.container("bg1").play();
                    bgOn = true;
                    else {
      sym.deletesymbol(); //If bar graph symbol is already on, when buttonbg is clicked again then delete "bg1"
      bgOn = false; // reset to false, click will relaunch "bg1"
Here's the project file.

==> file attached.
1) Symbol "stage", compositionReady:
sym.bgOn = false;
sym.$("buttonbg").click(function(){
if (!sym.bgOn) {
sym.bg1 = sym.createChildSymbol("bg1", "bargraph_container3").play();
//var container = sym.getSymbol("bargraph_container3");

} else {
sym.bg1.deleteSymbol(); //If bar graph symbol is already on, when buttonbg is clicked again then delete "bg1"

Help needed to handle buttons in the screen

hi
i have two buttons in my screen say button1 and button2
by default when i display this screen as per my requirement only button1 should be visible and button2 should be invisible
button2 should only be visible when i click on my first button i.e. button1.
where and how to code this
vamsi

Hi
You can use Modification groups while declaring the buttons. Assume we assign group1 as B1 for button1 and B2 for button 2.
fcode for button1 as BUT1 and fcode for button2 as BUT2.
at pbo
if sy-ucomm = 'BUT1'.
loop at screen.
case screen-group1.
when 'B1'.
     screen-active = '0'.
     modify screen.
when 'B2'.
     screen-active = '1'.
     modify screen.
endcase.
endloop.
else.
loop at screen.
case screen-group1.
when 'B2'.
     screen-active = '0'.
     modify screen.
when 'B1'.
     screen-active = '1'.
     modify screen.
endcase.

Dynamically Changing Labels for Multi Row Block Buttons

Forms [32 Bit] Version 9.0.4.1.0 (Production)
Oracle Database 10g Enterprise Edition Release 10.2.0.5.0 - 64bit Production
On my local: Windows 7 OS
I am having a difficult time in doing the following in forms, and not sure if it can be done?
I have a multi row block,based on DB table, which displays filename and another column from the table.
It also has a push button on each row, which opens and displays the physical file from its source, when clicked. The filename thus can have 3 diff statuses depending on its sources and accordingly corresponding button should display appropriate label:
a) View Image (its is in content server and successfully imaged. In this case I display the file in the browser, from the content server, when the button is clicked)
b) View File (Display the file from file system)
c) View Error (Display imaging error message from the table, as file failed to make it to the imaging server)
I have this logic currently coded in the post query trigger, at the block level, and tried using set_item_property(button_id, label, <button_lable>), where I programmatically set the button lable, based on the file status (imaged, not imaged or has error) in that row. This wroks well, only if all the files in the multi row block have the same status. If each of them have diff statuses, then only last processed files's status gets reflected into the button label. For eg: The file in the first row of the block is imaged, and one in the second row has an imaging error. The button label for the first row should say 'View Image' and button for the second row should say 'View Error'. But now buttons for both the rows display 'View Error', as thats what got processed last!
I __can not use set_item_instance property for 'label'__ (which lets us dynamically change the label on the push buttons).
Is there any way to do this for ORacle forms? I am now playing with having 3 diff button items in that block, laying them on top of each other and showing only those that are appropriate and hiding the others... But I am not sure it is going to give me what I need? I think I am going to end up facing the same issues as in above case!!
Any expert advice is highly appreciated.
Thanks in advance for your time:

<p>I have just updated this existing PJC, that was originally constructed to handle Text Fields. You can, now, also handle buttons with it.
Set the Button's Implementation Class property to : oracle.forms.fd.MultiButton.

This is the code you have to put one triggers of your based block:
When-New-Record-Instance trigger: (based on the EMP table)
declare
     LN$Pos pls_integer ;
     LN$Rec pls_integer := Get_Block_Property('EMP', CURRENT_RECORD) ;
     LN$Max pls_integer := Get_Block_Property('EMP', RECORDS_DISPLAYED) ;
     LC$C    Varchar2(15) ;
Begin
     LN$Pos := LN$Rec - (trunc(LN$Rec/LN$Max) * LN$Max) ;
     If LN$Pos = 0 Then LN$Pos := LN$Max ; End if ;
     If LN$Pos > 0 Then
          Set_Custom_Property('EMP.BT', LN$Pos, 'SET_LOG', 'true' );
          -- Add the new item --
          Set_Custom_Property('EMP.BT', LN$Pos, 'SET_NEW_REC', to_char(LN$Rec) );
          -- Set some properties --
          Set_Custom_Property('EMP.BT', LN$Pos, 'SET_LABEL', to_char(LN$Rec) || ',' || :EMP.ENAME );
          If :EMP.JOB = 'MANAGER' Then
            Set_Custom_Property('EMP.BT', LN$Pos, 'SET_FONT', to_char(LN$Rec) || ',Arial,bold,14' );
            Set_Custom_Property('EMP.BT', LN$Pos, 'SET_FGCOLOR', to_char(LN$Rec) || ',0,0,255' );
          End if ;

thanks in advance.
santhosh

Hi Santhosh,
   Check the following code.
* create a custom area on the screen
DATA : gref_ver_toolbar      TYPE REF TO cl_gui_toolbar,
       gref_custom_container TYPE REF TO cl_gui_custom_container.
* initializing toolbar
* Creating toolbar container............................................
create object gref_custom_container
exporting
container_name              = iv_ccarea   " control area on screen
exceptions
   cntl_error                  = 1
   cntl_system_error           = 2
   create_error                = 3
   lifetime_error              = 4
   lifetime_dynpro_dynpro_link = 5
   others                      = 6
* creating reference to toolbar........................................
create object gref_ver_toolbar

   others             = 4
* subroutine to create buttons
* Local data............................................................
data: lv_fcode       type ui_func,
        lv_icon        type iconname,
        lv_is_disabled type c,
        lv_quickinfo   type iconquick.

        lt_event type cntl_simple_events.
ls_event-eventid    = cl_gui_toolbar=>m_id_function_selected.
ls_event-appl_event = space.
append ls_event to lt_event.
* Method for Registering Events for Toolbar.............................
call method gref_toolbar->set_registered_events
    exporting
      events                    = lt_event[]
    exceptions
      cntl_error                = 1

      illegal_event_combination = 3
      others                    = 4.
* Setting handler for the Toolbar Buttons..............................
set handler gref_application->handle_function_selected
          for gref_toolbar.
just copy paste the above code in the PBO of the screen also you need to create a method handle_function_selected which will take care of the function on the button
* Method to handle button on toolbar....................................
     handle_function_selected
                    FOR EVENT function_selected
                           OF cl_gui_toolbar
                    IMPORTING fcode.
method handle_function_selected.
      case fcode.
        when 'DELETE'.
*          code...
     endcase.
endmethod.
Hope the above code snippet help you.
