Applet based Text Editor

Hi Genies
How can i create a Text Editor without using TextArea? I would like to use only AWT not Swing or Java 2. Any Idea ?
Shan

The AWT tools are woefully inadequete for creating a text editor. The AWT textarea does not support fonts, colors, custom line wrapping, line numbers, or anything else that would make a good text editor.
You could do it as an applet, but you would have to create your own text display by subclassing Canvas and writing text to specific locations. You would also have to write your own scrollbar, toolbar, button class that supports icons, etc.
It is usually just easier to make sure that people have swing installed. If you use a later version of Java, you can also do Java WebStart which will allow you to open and save files on the hard drive if the user chooses them. You can't do that easily with applets (requires signing your applet for $200 per year).
If you end up writing a text editor, I would suggest putting my syntax highlighting libraries into it:

Basics for a Java based text editor.

I want to try and write a simple java text editor I can upgrade as I learn more about java. Can anyone point me in the right direction or tell me the basic layout of a text editor?

I want to try and write a simple java text editor I
can upgrade as I learn more about java. Can anyone
point me in the right direction or tell me the basic
layout of a text editor?A text editor consists of three parts. User command interaction, text screen presentation and text data handling. Start with a small Java application with a GUI and check out the different Swing components and how they work. Internally the text can be held in a double-linked list where each blocks have space for 1000 characters or so. You'll also need some file handling to store the text externally.

Dynamic Text Editor

I am making a dynamic text editor.
Some of the fonts do not embed well? I have imported the
fonts, put a linkage name, assigned data to the label.
Some of the fonts change, but not on the server?
I am using the setTextFormat?
Does anyone have any ideas? It would be greatly appreciated,
Emma

Hello I am wondering if you can help me. I am sorry I have no
answer for your problem.
I am looking to also create a custom text editor in flash but
I have no idea on how to do that. Would you happen to have a
tutorial or can direct me to one on the web that I can learn how to
create such a thing?
I am looking for tutorials on this subject for both AS2 AND
AS3 based text editor creation.
Thank you.

Java Text Editor

I have created an applet editor that will enable a user to break a text file down into a series of smaller html files. This does serve a purpose that is not really important at the moment and I don't want to bore you all.
The problem I am having is that upon clicking the open button and the 2 save buttons, the applet opens file chooser where you can select a file. The problem is that once the file is open, the applet, for some reason starts the openfile() method again. The same happens when using the the 2 saveFile() methods. Can anyone help?

The apps listed at java-tips.org are just some of those that happen to be written in Java. If you want an editor that does syntax highlighting and other programming-specific tasks, you have dozens more options. A few Windows editors that spring to mind are EditPad, Crimson Editor, Scite, UltraEdit and Notetab. Then there are the old Unix standys, Emacs and vi, which have Windows versions as well. I use EditPad Pro, which isn't free like many of the others, but is worth the money anyway, IMO.

Query Regarding Rich Text Editor in Oracle 10G

Hello.
Can anyone let me know is their any privilege in Oracle 10g that we Incorporate the Rich Text Editor functionality. Currently we are working on Laboratory / Radiology Template based Reports in which they are requesting their should be option through which we can simply Cut and Paste our organized TEXT(REPORT) which are formatted in MS WORD with Bold,Underline and in Bullets format, it should simply paste in Editor and we can view a Template based report with formatted REPORT.
We are using Oracle 10G and it's Applet based Application. Any clue how can we Accomplish this? Any Suitable Suggestion?
Thanks

Sorry, I referred this already.. This also returns the HTML text. But i don't want the HTML text. I want Normal Text what i enter in the Editor. But as of now all the editors are returning HTML text. So in the front end also it is showing HTML text only.
I entered the text in Editor as
System Defaulted Note
Quote entered
But editor returns as below and the same way it is showing in the Front end application instead of above text.
<html>
<head>
</head>
<body>
System Defaulted Note

Options - Text Editor - C/C++ missing intellisense entry. Intellisense not working

Options -> Text Editor -> C/C++ missing intellisense entry. Intellisense not working. Solutions to turn options for the editor off and on are not working. The intellisense entry is present for other languages,
such as C#, but not C/C++.
By not working, I mean the intellisense right click menu items are grayed out, and intellisense files are not produced.

Hi JerroldBrody,
Thank you for posting in MSDN forum.
>>I mean the intellisense right click menu items are grayed out, and intellisense files are not produced.
Based on your issue, could you please share me a screen shot about the intellisense right click menu items are grayed out?
Generally, I know that it is default that we can enable the intellisense for C/C++ by going to the TOOLS->Options -> Text Editor -> C/C++ ->Advanced-> IntelliSense like the following screen shot.
So please try to check if you set Disable Intellisense property as False in the VS IDE.

How to call a text editor from a module pool program

Hi All,
I want to call the text editor from my modulepool program. Enter my text in it and save it.This text needs to be saved in a Z-program with 2 fields as primary keys. The next time while I call this same record from this z table, I need to fetch the existing text and display it.
The user now can put in additional text and can again save it. This process thus goes on..
If anyone has worked in this type of scenario, then please help me in doing this.
Useful answers will surely be rewarded.
Thanks,
Susanth.

Hi Sushanth,
We save the text not as fields in a ztable directly but as a text.Please check the format below since it is based on a working code....
first you need to create a text in s010 transaction...
there should be some key based on which you plan to save the text..imagine it is Purchase order then..PO+item numner is always unique.eg:0090010(900PO/item10).so in the code you can append these two and they will be unique..so you can always retrieve them,overwrite,save them anytime you need

Newbie help with sample Studio app. "Plain Text Editor"

I'm trying to make the jump from AppleScript to AppleScript Studio, and because I want to eventually write a document producing application I thought I'd start with the textbook example "Plain Text Editor" included with Xcode. I think I see how menu items are connected to "Target/Actions," and I was able to build and run it without difficulty. It's remarkable how little AppleScript had to be written to produce a rudamentary text editor. But in playing with the built application, I noticed that the Revert menu item does not work exactly as expected.
If you create a text document, and then make some change to it, and then click the Revert menu item, you get the expected little dialog asking if you want to revert to the most recently saved version, but if you then click the Revert button, the text displayed in the text view object does not revert to the original. However, something is happening, because whatever code is behind the Save, Close, and Quit menu items does seem to be "aware" that the Revert item has been invoked: because if you click one of these after Revert, the "do you want to save changes?" warning doesn't appear, just as one might expect.
The Revert menu item seems to be connected to a "Target/Action" called "revertDocumentToSaved:" which sounds perfectly reasonable. But does the fact that Revert doesn't cause the displayed editing text to revert mean that (a) there is a bug in the code behind this Target/Action, or (b) that the writer of this textbook example just didn't bother to do everything needed for the Revert item to work in an intuitive manner?
Whichever the answer, what would I do to make it work properely?
It seems like there must be some sort of connection between the text view object in the editing window, and the Close, Save, Quit suite of menu items, because the behavior of these is dependant on whether or not there are unsaved changes in the text view object. But looking through the Inspector for this object, I don't see any, neither AppleScripts, nor Outlets, nor Target/Actions. Where and for what should I be looking?

I think -- and I'm sure someone will correct me if I'm wrong -- that this is a place where AppleScript Studio's implementation just isn't done right. Either they intended to add a "revert" handler somewhere and forgot, or else they meant to have it send an existing message and didn't.
I haven't done any document-based applications -- heck, I've only dabbled slightly in AppleScript Studio -- so there may be a "deeper" answer to this, but you might consider just hooking the menu item up to send its "choose menu item" handler to your document script, and have it react accordingly.

Using the Document Manager Rich Text Editor

I'm wondering whether there is a reasonable way we can use the Rich Text Editor (based on CKEditor) that is contained within the Document Manager task flow (primarily for editing Wiki pages) outside of the Document Manager itself? We have another type of content we need a Rich Text Editor for, but it would be great if we could use the inline image links, tables, links to documents in the content repository, etc.

Have you consider use Site Studio + Content Presenter?

Max characters in a Rich Text Editor?

Is there a "hard limit" on the number of characters I can enter into a Rich Text Editor?
My testing suggests that you can only have 4000 characters. If i submit more than 4000 i.e. 4001, I get the following error message:
ORA-01461: can bind a LONG value only for insert into a LONG column
The data type I am trying to insert into is of type CLOB (which if memory serves can store upto 4 GIG).
We are using Oracle Application Server (Apache and MOD_PLSQL) so I imaging that there is possible a limit here as well with how much data can be posted.
Thanks for any help.

Hi Duncs,
I tried to reproduce your problem on our internal development system but was not able to do so. What did I do?
1) Created a new table with the following statement
CREATE TABLE DEPT_WITH_CLOB
   (     "DEPTNO" NUMBER(2,0),
     "DNAME" VARCHAR2(14),
     "LOC" VARCHAR2(13),
     "MORE_TEXT" CLOB,
      PRIMARY KEY ("DEPTNO") ENABLE
   ) ;2) Created a new application with a "Report and Form" based on the DEPT_WITH_CLOB table.
3) Modified P2_MORE_TEXT to use Rich Text Editor as item type.
4) Executed the page and entered a text which was more than 18,000 char long
5) Clicked apply changes and everything was stored without a problem.
Can you provide more information about your system?
1) APEX version
2) Database Version
3) Do you use database links in your apps or do other applications use database links?
4) If yes, which database version are those databases?
5) If you are able to reproduce the problem on apex.oracle.com that would also be of great help.
Thanks
Patrick

Rich Text editor in Webdynpro

Hi,
With the new FormattedTextView in 2004s one will be able to render xhtml compliant rich test in Webdynpro.
This however only covers the rednering of rich text.
There still does not seem to be a rich text editor control available for webdynpro applications, which I think might be a common requirement for document centric applications.
I was wondering :
1 - will there be a richt text editor control available for WDP in the forseeable future ?
2 - if not, are there any workardounds available to allow for the generation of rich text ?

Hi Valery,
Well, I already thought of that kind of solution, but I do not consider it a very clean solution. I know WDP supports portal eventing. On the other side of such a scenario you could even do without a 3rd party wysiwyg editor, cause SAP does offer an html editor control in its set of HTMLB controls.
We intend to use WDP as a UI layer on top of SAPs KM. Our scenario involves template based publishing of structured documents (we first looked at xml forms, but they showed too many limitations). The idea is to model the document structure and content at runtime as WDP context structures (based on xml schemas) and then to serialize WDP context into XML content and metadata, with KM acting as business and persistence layer. Markup and insertion of images into the different text parts of the document however has become an additional requirement, which is why we are looking for a ways to fit that in our current design.
You could indeed think of some kind of data exchange between a regular portal component and the wdp application, but I am not too confident whether that is going to be a reliable solution.
PS : for the serialization of WDP context, your post in a different thread on this forum helped me a lot in my first attempts to create KM documents from data wdp runtime data (context). The link provided to the online book and your little example was very welcome. Thanks for that !

Using Rich Text Editor with a Custom Attribute

Hello All,
Can anyone please tell me as how can I use the Rich Text Editor with a Custom Attribute?
I want to create a custom attribute based on text datatype, but when entering the value for this attribute in a Custom Item, portal shows a normal textarea. I want that the user should see the Richt Text Editor.
Thanks for help.
Regards

Hi,
Can you tell me what steps you are using to produce this, and which Portal version you are using. When I tried it, I wasn't able to reproduce it. Here are my steps:
1) Created Custom Item Type, based on Text, under
Page Groups > Shared Objects > Item Types
2) Selected Three attributes (Description, Name, Publish Date). Note Text and Display Name were already selected
3) In Add Item Wizard, configured list to allow for my
custom item type selection.
4) Then I was able to see the Rich Text Editor when editin
my custom item type.
Regards,
J.

Using rich text editor in new asset type input form

Hey everyone,
I'm currently trying to create assets based on a newly created asset type (which I of course, created). However, the STORAGE property I declared in the asset definition file is to support formatted text, which would normally be pasted from word documents. Note that I'm using the Basic Asset Model.
Thus, I need a rich-text editor to be used in the content input form. So, after looking at the tags reference in the developer's documentation, I thought that I could use EWEBEDITPRO to achieve my goal but there's always an error mentionning that the component can't be launched. I supposedly have to configure two parameters, one of them being the path for ewebeditpro.js. I looked for that but haven't found it. On the other hand, I looked at the Oracle WebCenter Sites Property File document and that one stated that EWEBEDITPRO is deprecated and not supported (?!?!).
So in short, what can I use, as a rich-text/html editor?? Thanks in advance for any reply!

Thanks. From what I've read in the developer's guide, CKEditor was available with assets built from the Flex model. However, I'm currently having a hard time trying to display the content of an attribute with content input through the CKEditor, because it's stored in a blob. Although I've found several examples showing how to read the content of a blob, none of them worked for me...

[SOLVED] recommendation for a text editor that can handle 25mb+ files?

Not sure where to put it, so I put it her (if it's not the right place, can someone please move it.. thanks!)
I'm building a database of about 60,000 files in folder X.
I'm using php to organise all the files and clean them up (for exmaple removing "-" and ":") and then sticking them into a database.
my main text editor is vim,and then I usually use a gui based editor for fast navigation (lets see you go through 1,010,131 lines of output in vim).
The output is usually suppressed, but the amount of files in X, changes daily (one day can go without change, then next day a user can add 20 files and another user can remove a file), so whenever a new file comes in I want to see that my code can handle it properly, then be able to stick in thee db properly.
recently trying to open a 1million line file in Kate, or Kwrite seems to crash dolphin (KDE).
If I install gvim, I'll need to remove Vim, and I dont want to do that.
I'm looking for something small with scroll bars, that only needs to edit txt files.

thanks for the suggestions thought , I see I have to work on my VIM navigation skills
If you know that it's some specific subdirectory that usually messes up, or you know the name of the file you want to find, you can do /FILENAME to search for it. If you know it usually is around line 600,000, then try out 600000G.

RTE Rich Text Editor

Hi Guys,
Anyone aware of a stable RTE Rich Text Editor code that can
be included in a record update page?
I need to have a RTE that allows for multiple fields. Most
only seem to allow for one field and do not work well with ASP code
and their Javascript.
Any suggestions welcomed please.
Thanks Jules

The TinyMCE "fine print" says it requires additional
extensions when using
FireFox for "some functions"
