Added Jcombobox into awt.frame causing handling event function cannot receive event
Dear Sir,
I want to ask how an awt.Choice can set the number of rows that it can display, like the method setMaximumRowCount in JCombobox. Since I want to set more row can be displayed, but choice no any method can set. And I have tried to add Jcombobox into awt.frame, then, the handling event function cannot receive event for the right-top cornet button(minimize, maximum, close).
Best Regards,
please post a Short, Self Contained, Correct Example showing your problem.
bye

Adding ClientCertLoginModule into SOAP adapter causes problem for HTTP
Hi there,
We are configuring SOAP adapter to use HTTPS with client authentication
for a B2B project. We followed note 891877 to add ClientCertLoginModule
into service sap.com/com.sap.aii.af.soapadapter*XIOAPAdapter in the
security provider service,
ClientCertLoginModule, SUFFICIENT
BasicPasswordLoginModule, SUFFICIENT
The interface for the B2B project works fine after the change.
But other interfaces which are using HTTP to connect to SOAP adapter
are all failing with HTTP code 302. Because all these interfaces are
using HTTP protocal with username/password for authentication, we
expect they should still work because the BasicPasswordLoginModule is
listed in the login module stack.
Any help is much appreciated..Hi there,

Adding Data into text and graphic frames - PLEASE CAN SOMEONE HELP?
Hello Script buddies,
Here is my script and I want to place data into the frames which I set up already in the inDesign template which loads correctly but unable to place the data into the frames, please refer to comments and if anyone can help me I will be very grateful.

WScript.QuitHi Robert,
Your problem starts here:
Set DepthMarker = myDocument.Textframes.Item
...which item? Item takes either an integer (the index of the item) or a string (the contents of the label property, if any).
Next, however, is that you should be more specific about *where* the text frame is in the document. What page or spread is it on? Let's say that the frame "DepthMarker" is on page 1:
Set DepthMarker = myDocument.Pages.Item(1).TextFrames.Item(1)
If there's only one frame on that page, you're in great shape. If not, you need to come up with some way to differentiate one frame from another. Script labels are a great way to do this. Let's say you've used the Script Label panel to add the label "DepthMarker" to the relevant frame on page 1, and added the label "WarningText" to another frame. In that case, you'd use something like this:
Set DepthMarker = myDocument.Pages.Item(1).TextFrames.Item("DepthMarker")(0)
Set WarningText = myDocument.Pages.Item(1).TextFrames.Item("WarningText")(0)
...When you use a string to refer to a page item by its label, InDesign returns an array, so you need to get the first item in the array (assuming that there's only one page item on the page with that label).
Hope this makes sense! I'm typing it off the top of my head because I have to go speak at a conference tomorrow and am short on time--but it should get you pointed in the right direction.
Thanks,

Event handler in later sequence frame is handling my event
Consider a case where you have a sequence with two frames. Each frame has an event handler. If you are in frame 0 processing events, do you think that the event handler in frame 1 should have any relevance? The attached vi demonstrates that it does. This seems like a bug to me or at least something to watch out for. I spent a half-day trying to figure this one out.
kc64 wrote:
I read the caveats and recommendations several times. I recognize that my example vi shows two event structures in one loop but, in my application , this is not the case. I don't see any clear instruction on that help page that would indicate that I have broken some rule of event structure use.
That's bothersome. I use sequences all the time and nobody has ever commented that my code is badly designed. I wonder why NI provides that function if it promotes poor code design. You did say "often" and not "always" so I have an out. :^)
Well, maybe they missed something in the caveats But using more than one Event Structure is not a good idea.
I just posted something to that effect this morning: http://forums.ni.com/ni/board/message?board.id=170&thread.id=337440
As for using a sequence structure (especially Stacked Sequences), I totally agree with Denis that it is poor design. Unfortunatley, NI cannot remove them from the palette due to compatibility with older versions. I would vote that they be removed ASAP.
However, it is your choice to follow other people's advice or not to follow it.

Hi!
I would like to know which one of the following is the best way to handle events in Swing application.
Method 1
Write annonymus inner classes in the same class
Method 2
=======
Write a seperate class which extends the adapter class of the event handling and create an object of that in the main class and assign it to the components with addActionHandler() method.
I am trying to use the second one and I have the following design issue.
I have a class frmMain.java in which I have a frame and to that frame I am adding a panel which consists of 'N' No. of components.
I want to make this panel added to the frame when I click on a menu item (login) and want to remove the panel from frame when I click on a menu item(logout).
I have a main class called Application.java where I create the object of my frame(frmMain.java).
Thanks in advance,
AV1. Your JFrame is now subject to receive action events from anywhere. You will have to be more careful that you respond only to the right events.
2. If you have a lot of possible consequences to an event(for example, based on button pressed), you'll need a long if...then...else statement to determine what to do based on the source of the event.
3. With individual ActionListener classes, it's easier to add the same listener to multiple components and no need to worry about source.
4. Kind of the same thing: With individual classes, the event and its consequences are so tightly coupled.
End preaching....basically, my style boils down to what I call the tool set vs Swiss army knife rule. Java seems designed around the concept of a large number of specific purpose classes vs a smaller number of multi purpose classes and I think its a design methodology that makes sense, because I believe strongly in functional isolation in my code. -

How to prevent the automatic full-white repainting of an AWT Frame?
Using Java 1.6.0, Windows XP, 1.6.0-b105 Client VM I have the following problem:
I made a double buffered AWT frame. But it still flashes sometimes. It gives one flash about 6 seconds after start of application. There seems to be an incoming event "for no discernible reason". I have overridden all paint/repaint/update methods in my Frame sub class.
These unwanted flashes are caused by the AWT painting the frame in white and then calling paint.
I may have caught these weird calls:
The good/normal case looks like:
java.lang.Exception: Stack trace

at java.awt.EventDispatchThread.run(EventDispatchThread.java:121)
The differences in the bad case: (Not all traces of this kind cause the flashing. But after all flashes there seems to be such a trace.)

So how do I stop these unwanted white redraws of the Frame?Accidentally found the answer:

How to open page in new window while handling event on link.
Hi all
I have a requirement where page should be opened in new window when I click on link.My item style is 'link'.Despite of mentioning target frame _blank, I m not able to open it in new window.I m handling event by setting Action Type as fireAction.I hope this might be the reason because of that this happened. Can somebody suggest some solution so that I can open it in new window.
Thanks,
BhupendraHi ,
though i am not able to answer, i can get some answer for my question.
How the link item is handled thru the ActionType and event in the Client Action..?
The reason for this question is that we are trying to extend the customer search page in AR - EBSR12. there the search result page has the Account Name as a link and the Action event says viewAccountName and the action type says firePartialAction. I am trying to understand this so that i can add more parameters to the link so that i can use them in the target page of the link..
Any help is appreciated..
Thanks

SiriHi Sirisha,
You can get the event code for Enter because you have regitered in the event reciever .
But for the SAVE you will have to set in the PF-status of the screen and not the ALV-grid save .

Photos are being added to my iPad, without choosing any events in iPhoto or having them sync with iCloud
I just upgraded to IOS6, and now my ipad is full of pictures I did not choose to sync.
I cannot delete them without deleting them from all sources.
Actually, the message is when I go to hit EDIT, select a picture, and then choose DELETE: "This photo is used in an album. Do you want to delete it everywhere? Delete Everywhere"
Does that mean "Everywhere" on my iPad, or everywhere including whatever place on my computer it found the photos to begin with?
PLEASE HELP
Ps:
I've already done this:
To delete photos from your device
In iTunes, select the device icon in the Devices list on the left. Click the Photos tab in the resulting window.
Choose "Sync photos from."
On a Mac, choose iPhoto or Aperture from the pop-up menu.
On a Windows PC, choose Photoshop Album or Photoshop Elements from the pop-up menu.
Choose "Selected albums" and deselect the albums or collections you want to delete.
Click Apply.You can still sync the photos and keep the photos that are already on the device. You have to include all of the albums or events in the pictures folder that you sync from. If you are using iPhoto, select that in the Sync Photos from drop down menu and then select all of the albums or events that you want to sync. Make sure to check Selected Albums, events, faces and automatically include (no events). Using that option will allow you to choose exactly which albums and events to sync.
You have to remember that all photos must be included in every sync so you cannot sync photos from iPhoto today and then try to sync photos from another folder tomorrow, or you will erase all of the photos that were synced from iPhoto. You need to maintain one main Photos syncing folder for the photos that you want to transfer to the iPad. You can have subfolders within that one main folder and you can selectively sync those subfolders. You just have to place all of the photos that you want to sync into one main iPad syncing photos folder.
There are WiFi transfer apps that allow you to transfer photos to the iPad without having to sync with iTunes. I use this one. This app (and others like it) will allow you to use multiple computers to transfer photos.

Hello,
I'm very much confused about the handling events of JComboBox with ActionListener and ItemListener. Both are seemed similar to me. If anyone can explain me the differences, it would be helpful for me. Thanks everybody.ActionEvents are fired each time any item is selected, ItemEvents are only fired, if the selection changes.

Handling events in BSP application using WML tag Extensions
Hello Everyone ,
We are developing a BSP applications for Mobile handheld using WML tag library. I am looking for some code samples to know how we can handle evevents inside the BSP using the WML tag library.
Can any one of you plesae help us by placing a code snippet for handling onInputprocessing() methods (BSP Using WML Tag extensions).
I mean to ask how we can handle events inside the BSP applications that uses the WML tag library.
I know about how to handle BSP events using HTMLB and XHTMLB tags frameworks.
Thanks for your help in advance.
Thanks,
GreetsonIs this WML tag library something that is supplied by SAP u2013 as a BSP Extension Element? Or are you just using WML tags directly in your layout? I can tell you in general that if you want to generate HTMLB events from regular HTML code you can generate the JavaScript calls using the htmlbEvent tag of the BSP extension library. However your tags have to be running within an HTMLB Content tag for this to work.
If you want to work totally without HTMLB then you need to use the simple HTTP Post but format the input name as OnInputProcessing(<function code>) like this:
<input type="submit" name="OnInputProcessing(ok)" value="OK">
This will cause the OnInputProcessing event handler to trigger without needing any HTMLB tags (this is how it was done in WebAS 6.10 before we BSP Extensions). -
Handling Events in FXML-includes
Hi!
I am using FXML to define the GUI of my application. As the GUI is pretty complex with many regions and items in it, I have created a separate FXML file for each main region to reduce the overall complexity of maintaining the design.
My parent FXML file, called "Frame.xml", includes those "sub-regional" FXML-definitions using "<fx:include source="RegionXYZ.fxml" />".
What I am now stucked with is, how to handle events in this approach...
Questions:
a) Can I add a separate controller in each of the "sub-regional" FXML-files, like "fx:controller="FXMLRegionXYZController"?
b) Or must I, or even should I, use only a single controller inside the main FXML? Will this single controller be able to recognize and handle actions/events in the included FXML-definitions as well?
c) What is the best approach in general for this?
Thanks,

- if you could control everything from a single controller but you option (A) is much better
c) What is the best approach in general for this?
- Option (a)
