How to follow/trace an event in Xcode

How do you trace a Cocao event/message? For example, how do you follow a touch event on a UITableView cell on the iPhone screen up to the tabbleView:didSelectRowAtIndexPath: callback of a UITableViewController based class?
If I put a breakpoint in the tabbleView:didSelectRowAtIndexPath: callback I can see a call stack. How can I put breakpoint within the Cocoa/Core/Library stuff ? It seems like I can only see source code for either bottom end ( int main(int argc, char *argv[]) or top end ( didSelectRowAtIndexPath ... ) It does not seem possible to put a breakpoint on th Cocoa/core/library functions in in between.
I did figured out I could add breakpoints for something like the global 'sendEvent' but that is quite low level and still pretty far from an actual target object. How can I trace objects in between?

OOPS!!
I posted my question in the wrong community

How can we trace the event

Hello Expert,
We have a lot of process chain which was trigger by one event with different variant. However, since the last two days, the process chain did not run. it seems the event was not triggered.
How can we trace the event? I mean, if it is triggered or not within one day.
As I checked the process chain, some of the process chain was successfully triggered by the same event. it is really weird...
Thanks

Hi......
Copy the event...........then go to SE16 >> RSEVENTHEAD............there in the event field give the event name.........then execute............from there you will get the event collector name................
If you don't get it here then search in table RSEVENTCHAIN.........
Copy the event and go to RSA1OLD(if you are in 7.0)............otherwise go to RSA1...............from there go to the Event collector........give the event collector name and check whether it registered or not............if registered when last it was registered.............if you are unable to find this event in these two chains............then go SM37................from there choose the event..........and in the Job field write BI_PROCESS_TRIGGER..............from there check when this job last triggered for this event.............
Hope this helps.........

How to trace an event

Hello,
If your requirement is to start a workflow for the creation of a material, please make an entry in the tcode SWECwith the following inputs,
Change doc. object = MATERIAL
Object Type = BUS1001006 or the BO that you are going to use, but make sure that the key fields of the change document object and the business object are same.
Event = Event of the BO.
check the 'On Create' radio button for Triggering event.
Hope this will help.
Thanks,

How to use JDI handle event, need you help!~

Hi,
In our recent project, I need listen some event such as ClassPrepareEvent, MethodEntryEvent using JDI and handle it. I am trying to mend the TTY and let it
do something simple when MethodEntryEvent occur.
I just add a print line in the method methodEntryEvent in TTY.java. But I noticed that this method is not invocated after I input "run" commond. I don't konw why? And how can I listen this event? And when the methodEntryEvent method in TTY will be invocated?
Anyone can help me ???
Thank you!!!
PS: methodEntryEvent method is post as follow:
public void methodEntryEvent(MethodEntryEvent me) {
Thread.yield(); // fetch output
//notice:
//i want print this sentens when every method entry.
System.out.println("Method Entry:");
StringBuffer buffer = new StringBuffer("\nMethod Entered: ");
buffer.append(me.method().declaringType().name());
buffer.append(".");
buffer.append(me.method().name());
buffer.append(" ");
out.print(buffer.toString());
otherEvent(me);
Duan
SJTU

You must enable a MethodEntryRequest before any MethodEntryEvent will
be reported.
In the jdb/TTY reference debugger, use the 'trace methods [thread]'
and 'untrace methods [thread]' commands to turn tracing on or off
for method entry and exit.
Once you request MethodEntry/Exit notification, then the methodEntryEvent
handler in TTY.java will be called and you will see the println() you
added to the code.

How can I get the events from a java program?

I want to make a monitor to watch a java program.How can I get the events from the GUI of this program some as mouse cliking, keyinput. So I can watch these in my monitor.
Thanks

Hi,
To put a monitor to the events occuring in the GHUI u need to register required components with the appropriate EventListeners.
Liek if u want to get notified when a mouse is clicked, then u need to add The MouseListener to the component which u want to be monitored.
Say
myFrame which is the JFrame object which shuld be monitored for the events.
Then in ur program u have to add following code
myFrame.addMouseListener( someObectReference );
Here the someObjectReference should be an instance to a concrete class ..i.e. U write a class like the following
public class MyMouseListener implements MouseListener {
// override the followig methods
public void mouseClicked(MouseEvent me){ sop("MOUSE CLICKED ON THE FRAME");}
public void mousePressed(MouseEvent me){}
public void mouseReleased(MouseEvent me){}
If u dont want to use another class for listening to the events. Then u can make teh current class monitor the events. To do so ur class should implement the appropriate listener and should override the required methods.
and u should say myFrame.addMouseListenet( this );
thats it

How to handle tab change event in UI shell main area

Hi,
I have two tabs(two taskflows) in UI shell main area. one is department tab and another is employee tab. My department tab shows employees department wise. On employee tab I have emplyee table which shows employees jobwise. This employee table has the functionality of adding new record to employee vo as well.
Now i follow these steps.
1. by defualt department tab is open.
2. by clickinng on Tasks menu link i open Employee tab in to main area. Now i have both tabs in main area.
3. at Employee tab I search all employees job = accountant. It shows the search result well.
4. Now i add a new record to it and without saving/deleting this record i move to department tab.
5. at Department tab i search employees where department =20, here no relation b/w job and department.
6. Now i return to employee tab. my newly added record got disappeared. It is there but does not show in table.
How to resolve it??
I have one solution in my mind while changing the tab i can prompt to user "you can not leave the newly added record..either save it or delete it". But how to catch tab change event here? where i can write code to prompt msg to user?
Pls help.

With apologies for the slow reply, I'm currently travelling.
Two things to note:
1) The af:document uncommittedDataWarning flag was designed to stop users navigating away from half entered records. More about this flag can be found here:
http://docs.oracle.com/cd/E23943_01/web.1111/b31973/af_orgpage.htm#CACDDDFH (see point 4)
http://www.oracle.com/technetwork/developer-tools/adf/unsaveddatawarning-096556.html
....please note our documentation from time to time spells this flag wrong with only one "t" in the word committed, so if you're attempting a bulk search check for this (and I'll raise document bugs to get this fixed in the future).
2) On addressing the ADF UI Shell, if you're switching between "pages" in the UI Shell, as separate to switching between dynamic tabs within a single page using the UI Shell, the UI Shell will actually restart the currently running task flow in the page you're returning too. You can verify this by implementing an initializer on your task flow with a log message, and watching when the initializer is called.
In addressing your last question, at this stage I think you need to assess my first answer then come back if you think you sill need to execute the code on the tab click. I also need to know are you talking about the primary level of tabs that represent each page in the UI Shell, or are you referring to the dynamic tabs within a single UI Shell page that hold your task flows?

How to handle double click event in a text control

Hi,
   Will u please send me information on handling double click events inside text control and also about locking and unlocking of DB tables for updation.
Regards,
Praba.

Hi Prabhavathi,
Here is how you handle double click events in Textedit control.
1)Create a custom control in screen (say TEXT_CONTROL)
2)In main program,
a) Declarations:
data: obj type ref to cl_gui_custiom_control.
      text type ref to cl_gui_textedit.
b) Create the instance of custom container
c) Create the instance of textedit control.
3)Now to handle double click events , create a local class as follows.
class shail_event definition.
public section.
methods:
handle_doubleclick for event dblclick of cl_gui_textedit .
endclass.
class shail_event implementation.
method handle_doubleclick .
here do the coding for handling the double click.
endmethod.
endclass.
4) Create an instance of the handler class(ie.ZSHAIL_EVENT).Let it be named hand.
5) Define varibles for event.
DATA: i_events TYPE cntl_simple_events,
      wa_events TYPE cntl_simple_event.
SET HANDLER hand->handle_doubleclick for text.
wa_events-eventid = cl_gui_textedit=>event_double_click.
wa_events-appl_event = 'X'. "This is an application event
APPEND wa_events TO i_events.
6)
    CALL METHOD texte->set_registered_events
      EXPORTING
        events                    = i_events
      EXCEPTIONS
        cntl_error                = 1
        cntl_system_error         = 2
        illegal_event_combination = 3
        OTHERS                    = 4.
    IF sy-subrc <> 0.
     MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
                WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    ENDIF.
These are the basic steps needed for handling events in Textedit control.You can go to SE24 and type CL_GUI_TEXTEDIT to find the associated events of the class.
If you want the program, kindly send your mail-id so that I can mail it to you.
Regards,
Sylendra.

Hi Naveen,
i think we use ABAP program under general services to generate an event.
searching form gave me following threads which might be helpfull
1) explains Evenet generation [Event raising procedure]
other helpfull threads
[Standard tools for Event raising]
[Event in Process Chain]
i could get the process for triggering it weekly,,,it may giv u some help in resolving
change the Start Process (1st process) in your Process Chain to trigger it to start after the event. To do this, maintain the Start Process of your Process Chain. Select "Direct Scheduling" and click the "Change Selections" icon. This will bring up a Start Time window. Click the "After Event" icon and enter your event name. Also, click the "Periodic Job" (this will insure that all the jobs created for each process in the Process Chain will reschedule themselves after executing the first time). Now save the Start Process, and reactivate and schedule the Process Chain.
To execute the Process Chain, use transaction SM64 to trigger the event.
If you want to trigger the event in batch, you will need to create an ABAP program that calls function module BP_EVENT_RAISE (sample ABAP code is available in this forum if you search for "BP_EVENT_RAISE").
We create batch jobs where we call an external program called SAPEVT, located on the server, and I believe is available on all SAP clients, with the following parameter:
EVTID('WEEKLY_PROCESS') SID(PU3) NUMBER(00) EVTPARM()
This will trigger the event WEEKLY_PROCESS.
See if this helps.

I've come across the same thing, and went to the Mac App Store and downloaded and installed Xcode through that.
However, it seems to have put the new Xcode.app straight into the Applications folder, whereas before (v 4.2.1) was installed in Developer\Applications\Xcode.app. In fact, it still is!
How do I uninstall everything that belongs to Xcode 4.2.1 from my system, but leaving Xcode 4.4. It seems parts of the new Xcode (4.4) have been put into the \Developer\ folder as well, so it's not obvious what I would need to delete... Can anyone shed some light on this?
