Click handler for a span

Hi
I have a TextFlow which contains several span elements. (Each has an ID attribute.) When the user clicks on one of these spans, a pop up should appear whe the user can style the span.
I tried to assign a different event listener to each of the spans, but failed.
This brings the same result for both spans:
     element.tlf_internal::getEventMirror().addEventListener(MouseEvent.CLICK, regionClickHandler);
    public function regionClickHandler(evt:MouseEvent):void {
       Alert.show(evt.currentTarget.name.toString());
Any ideas?
Tobi

Thanks for your reply Richard!
I have
textFlow.interactionManager = editManager;
and no SelectionManager. (I assume only one of them can be used for a specific TextFlow instance).
It seems editManager.tlf_internal::computeSelectionIndex doesn't exist.
To all TLF implementers:
When a user clicks on a span in an editable TextFlow, my click handler should do something with that span (open a pop up containing a style editor for that span).
Is there a simple way to get the span that the user clicked on? It would be great if the event would have a method which returns that span.

How to get event.target/event.currentTarget for HTML-5 canvas for click handler

Hi,
I hope everyone is doing great.
I belong to Actionscript background and just started on Flash CC HTML-5 canvas.
How to get event.target or event.currentTarget in Flash CC for HTML-5 canvas for click event.
Like we used to do it in AS 3.0
btn.addEventListener(MouseEvent.CLICK , go);
function go(evt:MouseEvent){
trace(" evt - "+evt.currentTarget); // It will let us know the clicked target
For HTML-5
btn.addEventListener('click' , go.bind(this));
function go(evt){
console.log(" evt - "+evt.????t); // what is the correct syntax here?
Thanks,

Hey guys found the answer from stackoverflow
it is - evt.target

How to find out the set handler for a particular signal?

I have an interesting puzzle to solve. l'm investigating problems with someone else's code and I'd like to get the name of the handler that is set for SEGV. psig shows that the process catches SEGV, however I don't have access to the source code for all the libraries it links against and none of the source code I have sets a handler for SEGV. Is there a way to find out the name of the signal handler that is set for a particular signal in a process? I'm sure the source was compiled with cc -g. Solaris 8

Hello Haritha,
Please follow the path.
Go to RSA1 -> Metadata Repository ->DataStore Objects(ODS) -> Find you DSO(ODS) there and click on that, you will get all the details(Queries, Objects - Char, Key figures, update rules,etc..) related to that particular DSO(ODS), same is the case for Cube as well.

hi. maybe i did not make my self clear. okay, here's how this button works, you have a open dialog button, and a open dialog box, you click the file, and it loads in the data grid. now you click on the save button, and a message says file was saved, need
try / catch code, to catch this, if the file was not saved, or other errors, then a error friendly message, any code for this. read the article, but need a specific error handler for the save button, like i had for the open dialog file dialog box. any suggestions,
or links, to look at sample code. thanks.

Event Handling for Graphic Shapes

Hi guys,
I have a problem on the implementation of a piece of software that i'm making, to be more specific i implement a GUI. In this GUI i draw rectangles, lines and that kind of things.
The problem is that i want when clicking on a rectangle, an event to take place such as the drawing of something else, or a message, etc.
How am i to achieve that? I've tried many things but didn't succeeded it unfortunately. How am i going to "give" life to my rectangles by adding event handling for them? What code should i write?
Note: My class extends JPanel & i'm using paint(Graphics g) for drawing the shapes
Thanks,

Hi Jocelyn,
Thanks for that reply.
I tried the transactions SICF and WF_HANDCUST.
1. In SICF under sap>bc>webflow-->wshandler when i double click on wshandler it shows that the service is active. But when i right click on the same and try to TEST it, i get an error
Error in Web service execution
The launch handler was called with an incomplete parameter list 
I am not sure what this error means.
The configurations available in this service are as follows,
ICF path --> /default_host/sap/bc/webflow/

Decription --> English
Logon Procedure --> Standard
Security Requirements --> Standard
Basic Authentication --> Standard R/3 user
Anonymous logon data

I am not clear what id and password should be maintained here. Can you please help us on this.
2. When i try to generate the URL in WF_HANDCUST and test them i get a success message.

Click Handler

Hi,
this might be pretty simple, but I'm trying to find the
button component's click Handler in flash... can anyone help me
with this or help me with the action scripting for such an event...
thanks!

click handler is for component under flash MX & below,
you can find it under parameters at property inspector, or
component inspector...
in MX2004 & above, we can attach the script directly to
the component instance
on(click){
//do something
}

3.2 to 4.1 Upgrade - Error Handling for Unavailable Database Links

Hi,
I'm having a 3.2 -> 4.1 upgrade issue related to error handling for failed database links.
I have a conditional Exists button on a page that has a SQL query to linked tables. However, for the 10 minutes every day where the target of the database link is getting a cold backup, the query fails. In the old 3.2 apex I simply got an error inside the region where the button is located but otherwise the page was still visible:
"Invalid exists/not exists condition: ORA-02068: following severe error from MYDBLINK ORA-01034: ORACLE not available ORA-27101: shared memory realm does not exist"
However, in apex 4.1.0.00.32 I get the following unhandled error, and clicking "OK" takes me to the edit page when logged in as developer.
i.e., the page can't be run at all while the database links are failing in this one region.
Error Error processing condition.

General users see this:
Error Error processing condition.
ORA-01034: ORACLE not available ORA-02063: preceding line from MYDBLINK
clicking "OK" takes user to another page, not sure how apex decides which, but not a concern at the moment.
I've done a search and read the page http://www.inside-oracle-apex.com/apex-4-1-error-handling-improvements-part-1/ but the new apex error handling isn't clear to me, and I don't know if the apex_error_handling_example provided on that page would be applicable to this situation.

    end loop;
    return false;
exception when others then
    sys.htp.p('Invalid exists/not exists condition: ' || sys.htf.escape_sc(sqlerrm));

end;As a view is simply a query I'm surprised this should make any difference but it now looks similar to the 3.2 error, inside the region, when the linked database gets its morning cold backup, and this is fine:
Invalid exists/not exists condition: ORA-12518: TNS:listener could not hand off client connection

How to use common event handler for selected movie clips?

I have a 50-state map in a flash movie. Each state is a movie
clip.
Goal: when mouse moves over a state or is clicked in a state,
the state will be highlighted in a bright color and a small box
will pop up near the state and display some information about the
state.
Question: I know I can add mouse event handler for each state
movie clip. But this is simply not good since this has to be done
50 times and codes thus scattered different places. Ideally, I only
want to have one script that determines where the mouse position is
when events trigged and then do right things (highlight the state
and display info. in a pop-up). How can this be implemented?
Thanks!

There are a number of ways. Which way is best depends on how
you have things set up so far.
E.g. If they have an enumerable naming convention:
e.g. each clip is like state_0 , state_1 etc.
Then you can loop through them and assign them all to the
same mouse event handler via the loop. You would need properties
other than the name of the clip to identify the state. E.g. each
clip could contain its own data or the index could be a pointer to
the state data (objects with state name and info properties) in a
separate array.
//state clips named
for (var i=0;i<50;i++) {
this["state_"+i].stateindex=i;
this["state_"+i].onPress= statePressHandler;
var stateData:Array = [{name:"StateName,info:"this state
Info"}, name:"StateName,info:"this state Info"}, etc...]
function statePressHandler() {
trace(this);
trace(stateData[this.stateindex].name+"="+stateData[this.stateindex].info);
Other ways are possible too but the best approach depends on
how you have named the clips and whether you're creating them with
code or whether they're already on stage from authoring (my guess).
If they're already on stage and they're called "Alaska" etc, then I
would be inclined to put them all inside a container clip that
contains nothing else other than states. It would avoid the need
for an array of clip names or for checking some other specific
property of each clip to determine if its a 'state' clip and not
something else in a for..in loop.

Is there a Drag-Drop handler for TextAreas ?

Is there a Drag-drop handler for TextAreas where new x,y positions can be saved as well ? Thanks in advannce

Bernd, thanks for the helpful suggestion - I may be able to change my procedure and use that feature. It would save me thousands of mouse clicks if I just found and dragged each .doc into the target folder, then used an Action to convert them all to PDF. I still like the 'smart' folder idea, though....it would be a cool utility.

Unable to get automatic event handling for OK button.

Hello,
I have created a form using creatobject. This form contains an edit control and Search, Cancel buttons. I have set the Search buttons UID to "1" so it can handle the Enter key hit event. Instead its caption changes to Update when i start typing in the edit control and it does not respond to the Enter key hit. Cancel happens when Esc is hit.
My code looks like this -
Dim oCreationParams As SAPbouiCOM.FormCreationParams
        oCreationParams = SBO_Application.CreateObject(SAPbouiCOM.BoCreatableObjectType.cot_FormCreationParams)
        oCreationParams.UniqueID = "MySearchForm"
        oCreationParams.BorderStyle = SAPbouiCOM.BoFormBorderStyle.fbs_Sizable
                Dim oForm As SAPbouiCOM.Form = SBO_Application.Forms.AddEx(oCreationParams)
oForm.Visible = True
'// set the form properties
        oForm.Title = "Search Form"
        oForm.Left = 300
        oForm.ClientWidth = 500
        oForm.Top = 100
        oForm.ClientHeight = 240
        '// Adding Items to the form
        '// and setting their properties
        '// Adding an Ok button
        '// We get automatic event handling for
        '// the Ok and Cancel Buttons by setting
        '// their UIDs to 1 and 2 respectively
        oItem = oForm.Items.Add("1", SAPbouiCOM.BoFormItemTypes.it_BUTTON)
        oItem.Left = 5
        oItem.Width = 65
        oItem.Top = oForm.ClientHeight - 30
        oItem.Height = 19
        oButton = oItem.Specific
        oButton.Caption = "Search"
        '// Adding a Cancel button
        oItem = oForm.Items.Add("2", SAPbouiCOM.BoFormItemTypes.it_BUTTON)
        oItem.Left = 75
        oItem.Width = 65
        oItem.Top = oForm.ClientHeight - 30
        oItem.Height = 19
        oButton = oItem.Specific
        oButton.Caption = "Cancel"
oItem = oForm.Items.Add("NUM", SAPbouiCOM.BoFormItemTypes.it_EDIT)
        oItem.Left = 105
        oItem.Width = 140
        oItem.Top = 20
        oItem.Height = 16
        Dim oEditText As SAPbouiCOM.EditText = oItem.Specific
What changes do i have to make to get the enter key to work?
Thanks for your help.

Sheetal

Hello Felipe,
Thanks for pointing me to the correct direction.
So on refering to the documentation i tried out a few things. But I am still missing something here.
I made the following changes to my code -
oForm.AutoManaged = True
oForm.SupportedModes = 1 ' afm_Ok
oItem = oForm.Items.Add("1", SAPbouiCOM.BoFormItemTypes.it_BUTTON)
        oItem.Left = 5
        oItem.Width = 65
        oItem.Top = oForm.ClientHeight - 30
        oItem.Height = 19
oItem.SetAutoManagedAttribute(SAPbouiCOM.BoAutoManagedAttr.ama_Visible, 1, SAPbouiCOM.BoModeVisualBehavior.mvb_Default)
        oButton = oItem.Specific
        oButton.Caption = "OK"
AND
oForm.Mode = SAPbouiCOM.BoFormMode.fm_OK_MODE
oItem = oForm.Items.Add("1", SAPbouiCOM.BoFormItemTypes.it_BUTTON)
        oItem.Left = 5
        oItem.Width = 65
        oItem.Top = oForm.ClientHeight - 30
        oItem.Height = 19
oItem.AffectsFormMode = False
I get the same behaviour OK button changes to update and enter key does not work.
Could you please tell me find what is it that i am doing wrong?
