Lotus Notes のメイン UI にいくつかの UI を追加し、ユーザーがメールを作成して送信するときに次の処理を行う Lotus Notes プラグインを開発する必要があります。
これは Lotus Notes プラグインで実行できますか?
よろしくお願いします、ナディーム・ウラー
Java Lotus Notes API を使用して実行できると思います。ここから例をダウンロードしてください。 http://www.nsftools.com/tips/NotesTips.htm#javascraps javascraps.zip ファイルをダウンロードしてください。
作業を完了するには、Lotus Notes で Java エージェントを作成する必要があります。次に、Java API を使用して要件に従って Java コードを記述し、タスクを完了させる必要があります。

/*
* The MessageBox class allows you to create simple message boxes
* using only the java.awt classes. All you have to do is create an instance
* of a MessageBox and use it to call the doOkCancelDialog or the
* doInputBox methods. You can use a single MessageBox instance to
* create multiple dialogs.
*
* This class has been implemented here as an inner class, but there's
* no reason why it couldn't be a class all by itself. The functionality to
* create buttons and messageboxes has been modularized, so it should
* be easy for you to add your own methods to this class, or make global
* modifications as you desire.
*
* The only really complicated/weird thing I had to do was to write and
* include the MultiLineLabel class, which is included towards the end
* of this class as an inner class. Read the comments associated with
* that class to see what's going on there.
*
* Make sure you import java.awt.* and java.awt.event.*

* Okay, this is a pain, but java.awt doesn't natively have a Label-type class
* that allows you to display text that's more than one line. So I had to write one
* myself. The class below is a modification of some code from the fantastic
* book, "Java in a Nutshell".
*
* The big change I made was to allow this multi-line label to have a fixed width,
* so the Label wouldn't fly off the screen if you had a big paragraph of text to
* display. The width is specified in "columns", which I defined as the width of
* the letter "X" in whatever font is being used. The text that you add to the label
* is automatically split into chunks that are no longer than the number of columns
* specified (you'll see the code to do this in the parseLabel method).
*
* This sample implementation is an inner class of the MessageBox class, although
* it could also be a separate class all by itself. I made it an inner class to make it
* easier to copy and paste everything from one agent to another.
