We need an "Undo Autocorrect" button/method
It would be great to have a button/button combo that would undo the last autocorrection made and revert to the intended spelling.
Autocorrect as a whole is an excellent feature. What would make it even better is the option to undo the last autocorrect without having to delete what was inserted and type it all over again.
You can just dismiss the suggestion.

Hi to everyone!!!
I need your advice for my problem!!
when I cliked new in the file to create a new JTextPane the undo redo button will multiply and if I have so many JTextPane then I have many undo redo in my toolbar

Need to Add a button in ALV Tool Bar
Hi,
I have a requirement where in i need to add a button to a standard ALV report. Its using the class CL_GUI_ALV_GRID. There is a Badi for the report. The Report is co05n and the Badi is WORKORDER_INFOSYSTEM . I am getting the handle of
CL_GUI_ALV_GRID object reference before screen display. Any guidance on how to add new button now to that toolbar?
Any help will be rewarded.
Thank you.

Retrieving Vector Elements / Button methods
1.Hi, I have a small query regarding vectors. My applet is to dynamically create an arbitrary number of buttons, and to do that, in my init() method, I read in from a text file a list of button names/their associated URLs
I can create those buttons/URLs and store them in the vector, but now I have problems trying to access them.
I can't add the buttons into the applet area, since Vectors return an object of type Object and I need to use the add() method to add my buttons ( incompatible type ).
Is there anyway to "type cast" these objects back into button types, or am I stuck?
2.Also, is there a way to create more than one button ( each when clicked, loads a different URL ), without using arrays/vectors, but only with set/get action? If so, how?
Thanks in advance.For the first part you can cast the returned object into what is should be
so if we had:
vector.set(0,jbutton);
then we can do this:
(JButton)vector.get(0);
alternativley, you could store the urls in an object and construct the buttons later. -
Help please! I need code for a button to stop a movieclip, when both are in a nested animation.
I'm working on a project that has a button and a movieclip, which we want the button to stop, both nested in a movieclip on the main timeline.
The button instance = muteBtn
The clip to stop instance = backmusic
The movieclip they are nested in = ecard
There's also a preloader that works just fine on the main timeline.
I've seen a wide variety of ways to stop a streaming MP3 and they all look way too complicated for my current Flash knowledge level. As far as I know, if the MP3 is in a movieclip, stopping that clip will also stop the MP3. If that's just dead wrong and what I'm trying to do will never work, please just let me know so I can struggle in another direction.
What I'd prefer though would be the coding to make this button work. I've tried a wide variety of ways to code something that seems like it should be so simple, and keep getting the error "Access of undefined property muteBtn". I'm assuming this means it can't find the muteBtn in the nested layer. How do I better define the muteBtn? Do I then need to add something else that more clearly defines where the clip I want it to stop is since it is nested too? PLEASE HELP ME!! Thank you in advance!
Some of what I've tried:
function endMusic(e:Event):void {
ecard.backmusic.stop();
or
function endMusic(e:Event):void {
backmusic.stop();
with...
muteBtn.addEventListener(MouseEvent.CLICK, endMusic);When you target objects, you need to consider the path to the object based on where you are trying to target from. So if your code is in the main timeline and your button is inside a movieclip, then you need to target the button via the movieclip...
movieclipName.muteBtn.addEventListener(MouseEvent.CLICK, endMusic);
As far as stopping a moiveclip resulting in stopping a sound from playing, it is not likely to work. To stop a sound you need to target the sound to stop it. -
Undo/Redo button are not performing more than one operation at a time
Hi,
I have created undo/redo button on my paint application. But it performing only last action to undo.I have just the code which store offscreen image into undo buffer image like this :
if (OSC == null || widthOfOSC != getSize().width || heightOfOSC != getSize().height) {
// Create the OSC, or make a new one if canvas size has changed.
OSC = null; // (If OSC & undoBuffer already exist, this frees up the memory.)
undoBuffer = null;
OSC = createImage(getSize().width, getSize().height);
widthOfOSC = getSize().width;
heightOfOSC = getSize().height;
OSG = OSC.getGraphics(); // Graphics context for drawing to OSC.
OSG.setColor(getBackground());
OSG.dispose();
undoBuffer = createImage(widthOfOSC, heightOfOSC);
OSG = undoBuffer.getGraphics(); // Graphics context for drawing to the undoBuffer.
OSG.setColor(getBackground());
OSG.fillRect(0, 0,widthOfOSC, heightOfOSC);
and the button performed it's action :
else if (command.equals("Undo")) {
// Swap the off-screen canvas with the undoBuffer and repaint.
Image temp = OSC;
OSC = undoBuffer;
undoBuffer = temp;
repaint();I want to create undo button that performed end operation on canvas.
please help me
Thanks in advance....Don't post the same question repeatedly. I've removed the thread you started 4 days after this one with the identical same question.

I have a requirement, where I need to hide the default method that is getting displayed in the approval task of the workflow.
The employee object and Trip objects default method are getting displayed in the preview of approval task. And same is getting displayed in the universal worklist in the columns of attachments.
There is an option in univesal worklist configuration where we can remove the attachments for display.
But to our requirement , only certain objects and attachments should be shown in portal and R/3 of the approval task.We need to restrict the employee object and trip object which is shown in objects and attachments column of the standard descision task.
Let me have any suggestion on this.
Thanks in advance.
regards,
Sabari Prabhu.Hi,
I took a look into this same issue some time ago, and at least I didn't find a way to restrict only certain attachments for displaying in UWL. If the attachments cannot be hidden, I have tried to avoid using the business objects as much as possible. For example the employee object is many times binded to the task only because you want to display certain attributes in the task description. Then I have just binded the needed attributes into separate container elements. Of course this will not solve all the cases.
Then other useful options are that you change the default method, and this method is implemented in a way that it either does not display anything, or displays something (maybe just an error message etc.) that makes more sense than the default method that SAP delivers. Or then you can implement for example your own web dynpro application that will be launched when you click the attachment.

Need Help with a getText method
Gday all,
I need help with a getText method, i need to extract text from a JTextField. Although this text then needs to converted to a double so that i can multiply a number that i have already specified. As you may of guessed that the text i need to extract already will be in a double format.e.g 0.1 or 0.0000004 etc
Thanks for your help
ps heres what i have already done its not very good though
ToBeConverted.getText();
( need help here)
double amount = (and here)
total = (amount*.621371192);
Converted.setText("= " + total);Double.parseDouble( textField.getText() );

you can't use the button itself if you want to maintain the
DOWN state after
release as button automatically resets itself once the mouse
lives the HIT zone.
Use movie clip instead and on press simply send it to a frame
where there
is DOWN state like image.

Need to know of a method / process that can be used to send the same msg to all those appearing in my email listings with the same extension after the "@" sign in their address(es) on my macbook [Snow Leopard].
If you simply want to send the exact same message to everyone in your address book with emails ending in "@whatever.com", you can do the following:
Create an email with subject, message and attachments but no addresses
Open Address Book, All Contacts
Search in Address Book for @whatever.com
Select the results and drag them into the To: or Bcc: field of the email. If Bcc: then put your email address in the To: field.
Send the email
This will not personalize the emails (such as with "Dear firstname:" at the top of the message) but it will let you send an idential message to everyone who meets your criteria. -
In which case we need a class with all methods defined as abstract ?
In which case we need : A class with all methods defined as abstract (or should we go for Interface always in this case)
The concept of interface and abstract class overlaps sometime, but we can have the following thumb rule to use them for our specific need:
1) Interface: This should be use for code structuring. They standardize your application by providing a specific contract within and outside. If you think abstract class also provide structure, then reconsider as it limits the structure re-usability when there are many super-classes to inherit from. Java allow multiple inheritance by interface and not by Abstract class.
2) Abstract Class: This should be use for code-reusability. Interface doesn't have any code so can't be used for code-reusability.
Actually we can use both to provide the best.Taking a refernce to J2EE framework, the "Servlet" is an interface. It laids down the contract/structure for any code to be a servlet.
But the "GenericServlet" class is an abstract class which provides implementation of some of the methods defined in the "Servlet" interface and leave some method abstract.
Thus we see that the "Servlet" interface standardise the structure and the "GenericServlet" abstract class gives code re-usability.
Original Question:
In which case we need a class with all methods defined as abstract ?To this question, as all methods are abstarct we don't have option for code-reusability. so why not add standard structure concept to your application. So if there is not any restriction on making the field variable(if any) as final, we should go with the interface concept. -

Seriously need an Undo for assigning keywords... a couple of times now when in a Smartalbum showing various keywords, somehow I have managed to assign a new keyword to all photos, which mixes them up with other ones, and I have to manually go through them all again to remove the keyword as there is no "undo" when you assign the keywords.
ThanksThanks, have submitted it as a bug report, I cant think of the issue as anything else. Although I tend to prefer forums over bug reports/feature requests, I dont think in my life I have ever had any positive outcome when contacting large companies with bugs or feature requests. Usually the community provide much better support!

Need to undo file renaming upon import
Help!
I didn't see the tiny box checked that re-named hundreds of images when I imported them.
I need to undo this and get the files names back.
Anyone know how?Thanks! Don't know if I'll go this direction or not, I don't think my files need any rebuilding, etc, but was just curious if I could work between bridge and lightroom! Sometimes a lot eaiser to go to bridge, do your thing then have it be compatible with LR!
Quick and Dirty!:)
Thank You,
