Questions about Preferences:

6. What is the small icon that's displayed when double-clicked? How should I turn it on/off?
A. This icon is useful for those who dislike seeing a tooltip on double-click.This icon will remain visible for 5 seconds during which if you move your mouse over the icon, the tooltip or iframe is displayed. This is also useful for those who have a habit of double-clicking to select the word and copy the word. This icon allows to differentiate when you really want to view the meaning and when you want to select a word.

7. What are the preferences for invoking the tooltip?
A. The preferences allows you to customize how and when to show the tooltip. When you double-click on a word, the toolitp pops up. You can disable/enable the double-click feature by removing the check mark on the checkbox.Similarly there are other choices like Ctrl+Dbl-Click for those who feel double-click annoying. Alternatively, you can press Ctrl+Shift+K (or any key of your choice) or right-click and choose "View Definition" to invoke the tooltip.

8. How to set the location of the tooltip?
A. By default, the tooltip is shown near the selected word. You have a choice whether to show the tooltip near the selected word (or) always at the same location.

9. What are the list of all websites and preferred websites?
A. The list of all dictionaries (left list) is the total availabe dictionaries/websites. The preferred list (right) is the one that will be displayed on the dropdown in the tooltip. So, keep the dictionaries that you use the most in the preferred list so that your dropdown is not cluttered. These lists also enable to sort (order shown in the dropdown) the dictionaries/websites.

10.How do I import a new dictionary/website?
A As said in answer to Q. 2, the extension works by slicing of the unwanted part from the webpage, it uses XML for storage of code. You can import the code stored in xml to do the slicing for you from my website.

http://www.rjonna.com/ext/ext_download.php

Just select the websites/dictionaries that you want to add from the list and click "Download XML" button. Give the location you want to save the file. Then, click on the "Import Website" button from the "options" and select the file you downloaded. That's all, the dictionaries that you selected would appear in the list boxes/

11. How do I add a new dictionary? What is the difference between simple mode and expert mode?
A. Read answer to Q. 2 if you haven't read before proceeding. Simple Mode just allows you to add the dictionary/website to the list. It doesn't do the slicing. Expert mode allows you to add javascript code yourself to do the slicing if you know scripting.

Simple Mode:You have to provide information to only 3 fields.

Name : Give a name to the website that you add. This will be the name that is displayed in the dropdown.

Url : This is the actual url of the website. The "search term" has to be replaced by $$ (2 dollar signs). '$$' is replaced by the word you select on the webpage.
eg. actual url : http://www.thefreedictionary.com/arrow?p (actual url with 'arrow' as the search term). You may have to replace 'arrow' by $$.
converted url : http://www.thefreedictionary.com/$$?p

Sub Categories List: This list is the 2nd drop-down that usually has the conversion between different languages from the same website. For example, in dict.org there are many options to convert between languages. You can leave '*' if the dictionary/website that you add doesn't have any such language conversions. This is a comma separated list. To add multiple options, make it a comma separated string. They will be split as options and shown in the drop-down.

Expert Mode: You should know javascript and DOM (a must) to do this. If you don't know javascript send a request to me by giving the url and your email id(just to notify you after it's complete) at http://www.rjonna.com/ext/ext_download.php. I will do it in my free time.

I tried my best to make it simple..Ok. we shall start. Best way to start is look at the "Code Preview" for the existing dictionaries (particularly dict.org) (or) You can look at the actual generated script file in a directory called dictionarytip in your profiles folder. An array of these objects "arrDict" is created and called as shown below.

toolTip.curDict = arrDict[prefDict];
toolTip.curDict.assignUrl(this.selectedText); //this assigns the url and replaces $$ with the selected word
frameTip.setAttribute("src", this.curDict.url); //frameTip is the iframe object

After Page Load:
toolTip.curDict.filterPage(ftDoc); //this function filters the web content

How to fill the fields?

Sub Categories Value List: This is again the comma separated list which holds the 'value' part of the options in the dropdown. This should be in synchronous with the Sub Categories List. ie they should have the same number of comma separated values. What's the use of this? Take 'dict.org' as the example. This has many choices like converting from english-> english, en->spanish, spanish->en. This is what is shown in the drop-down. This field helps to show readable names in the drop-down and have the actual values in their 'value' fields. The actual value that's sent to the server is different. The values you provide in this field is sent to the server. See the url below to get an idea.

prefLang is the index variable for the 2nd dropdown. It is the "selectedIndex" for the dropdown.
this.subCatValue holds the comma separated string you enterd in this field

url = "http://www.dict.org/bin/Dict?Form=Dict1&Query=$$&Strategy=*&Database=" + this.subCatValue.split(",")[prefLang];

Code for Url: As seen above, if you need multiple options in the same dictionary you have to give a complex url. The variable 'url' stores the url which is provided as the source to the iframe.

Code to parse webpage: This is where you parse the webpage that's loaded in the iframe.You have the variable called 'ftDoc' which is the actual 'document' object for that iframe. You can filter the content using this ftDoc (document) object.

eg. (en.wiktionary.org) Look in the DOM Inspector for en.wiktionary.org

var newContent = ftDoc.getElementById("bodyContent").cloneNode(true);
var wiktionaryFont = ftDoc.createElement("font");
wiktionaryFont.setAttribute("size", "2");
wiktionaryFont.appendChild(newContent);

ftDoc.body.innerHTML = "";
ftDoc.body.appendChild(wiktionaryFont);

This code eliminates the outer table and shows only the content.

As said earlier, this is an experiment and I tried my best to make it simple. I am not yet sure if this works for all websites/dictionaries.
