Explanation of (undocumented?) XUL dialog attribute buttoniconaccept (and similar) - firefox-addon

I am pulling this attribute directly from Mozilla Firefox's about.xul file which shows the About dialog box for an add-on. It is a relatively simple XUL dialog with no inputs, locale data pulled from DTD entities, string bundle properties and JavaScript.
<!-- omni.ja!/chrome/toolkit/content/mozapps/extensions/about.xul -->
<!-- chrome://mozapps/content/extensions/about.xul -->
<dialog id="genericAbout"
xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"
onload="init();"
buttons="accept"
buttoniconaccept="close"
onaccept="close();">
MDN: Dialogs and Prompts and MDN: dialog both mention something about attributes that are formed by concatenating (pseudo-regexp):
"button" + "(label|accesskey|oncommand)" + "(accept|cancel|disclosure|help|extra[12])"
For example: buttonlabelaccept.
However, I could not find any documentation about the use of icon. The word icon does not even show up on either of the above-mentioned pages! What does it do? What is the correct way to use it?
I'm trying to make my add-on about page more modular, without loading internal files from omni.ja(r), which pulls in a LOT of unnecessary code with it. I am developing a very streamlined version, that will style itself appropriately depending on calling context.
I want it to look like Firefox's official About < addon.name > dialog if called from about:addons context-menu, or from my add-on's status-bar context-menu. I want a slightly different appearance if viewed from within the Options dialog as an iframe inside a XUL. I already have that structure set up. Just tweaking the little quirks.
This is not critical design or feature wise, and indeed the entire API will go away in a few months, but it just bothers me to not really understand this, so I want to figure it out before I let it go an move on to more important things. But I will if I absolutely can't find an answer. But it's one of those stupid little things that will just bother me a disproportionate amount. =D
If you can point me to documentation I may have missed, or even specific Mozilla source code, and a few examples, or a more complete explanation and typical use-cases, that would be great.

If you check the "blame" for about.xul, you'll see that the line was added to fix bug 422763. Judging from the screenshot in the bug, GNOME (Linux) has (had?) a convention of putting icons on dialog buttons, and this attribute allows overriding the default icon (inferred from the button type).
If you search for buttonicon, you'll find the code that handles this attribute in toolkit/content/widgets/dialog.xml.

How To Create a Standalone Swift SDK

I would like to create a SDK to use without iOS or Xcode.
Let me explain. I would like to use Swift language to create a framework with which to develop front-end. In few words with this framework I would like create html pages for web and substitute HTML, CSS and javascript with swift. The idea get from what Apple does with iOS. If you look how is made a xib or storyboard you can see xml file. I would like to do the same thing or take the idea and applicate for the web.
To do this I need to create an SDK that is not connected to iOS but that I can use in any IDE like VSCode or similar or also in a my own IDE created by me.
An other thing that could help you to understand what I mean is Javascript. In javascript there is a command createElement that let you to create an element, adding class, attribute and, yes, style. But create UI in this way, you understand well that is very hard. So, I Would like create a framework in iOS style, to create frontend in simpler and easier way.
I would like create create this framework (if it's possible) in Xcode and I don't want have any interference by iOS.
So, have you any suggests about how to start?
thank you
XIB layout is constraint-based, which means you describe your view hierarchy and constraints, and autolayout system does the layout for you every time according to constraints you've provided. Technically, inside it converts constraints to a system of linear equations and solves it in run-time, thus calculating frames for every UIView. And .xib file is just an XML with all the views, their properties and constraints. (that's a bit simplified, but you've got the idea)
HTML layout is totally different: HTML is a declarative way to describe elements on a page, i.e you describe every element with tags, and every tag (or its parent, or CSS file) already contains all necessary information about its positioning and appearance, so browser just parses and renders a page accordingly.
Theoretically, you could've reinvented a web browser: write your HTML parser, then write UI to somehow render it, and add feature to alter HTML tags by moving the page elements with mouse. But that would've taken a lot of time and effort :)
There are many website constructors on WWW, which allow you to build simple sites only with drag-and-drop (no coding needed). Also, you can inspect element in your browser, and then change some attributes of some element right in the debug window, and see changes in realtime.
P.S Im not a web/frontend developer, but I suppose that IDE's popular among frontenders already have some features or plugins that allow them to render HTML/CSS code and see changes in realtime, just like browser's debug menu.

Delphi: Set Browsers Homepage

I want my application to be able to set IE, Firefox, Chrome & Operas homepages when a button is pressed. I understand IEs homepage is set in the registry, which I understand how to change, but can anyone give me any help with the others? Thanks
Chrome stores the homepage in a file called 'Preferences'. On Windows XP, this is located at;
C:\Documents and Settings\USERNAME\Local Settings\Application
Data\Google\Chrome\User Data\Default
On Vista+, it's located at;
C:\Users\USERNAME\AppData\Local\Google\Chrome\User Data\Default
This file is JSON format, and so it can be opened and viewed as plain text. In order to change the homepage, you'd need to load the JSON from this file, and change the homepage field value. You may also need to change the homepage_changed field value in order for it to stick. Using something like SuperObject to change the field would be an easy solution (if I get time, I'll write up some example code later).
Firefox uses a pref.js file to store it's settings, and realistically, a way of changing this would be to load this file, find the something that's along the lines of;
user_pref("browser.startup.homepage", "[URL]");
...and edit it as appropriate before saving the file. This should be a simple task using some simple find-and-replace code. I'd strongly advise that you use a pos() function though, as it could be that the end-user has already got their own custom homepage set and so searching for a preset string (e.g. [URL]) may not work, and certainly wouldn't be reliable.
A quick search hasn't given me enough information about Opera to provide a solution, but I'll keep looking and respond if I do find such a way.
Note that none of these methods have been tested and are merely provided based upon some very quick research.

how to create a window in firefox that looks like "lookup" window in mac os

I am trying to design a firefox extension which shows some information for the selected word in the page.
for those information I like to have a window with no boarders and with a pointer pointing to the selected word. something like this picture (lookup feature in mac os):
sample1
here is another example from firefox itself:
sample2
any idea on how I can create this kind of windows is highly appreciated.
I think you're looking for a Panel to do this and you could likely use the Selection module as well to work with the text. However you'll find it a little challenging to get your panel to point to the text like you want, currently the Panel doesn't easily support positioning like that.

textarea that was using plain text with option of markdown or textile filter now needs images

My clients can enter text into textarea and have the option to use the markdown or textile filters for each textarea.
With some models (articles, newsletter, etc) they can upload images to associate with the model, which are displayed in a column next to the text of the text.
This worked fine for a while, but they have now told me that the want the ability to put the images INSIDE the text a specific positions.
What is the best way to go about this? I suppose I may have to use a wysiwyg for this, but would rather not. And how would this work for images which are not yet on the server, etc?
There are different directions you could go to:
Follow the path of Confluence, which released in their new version 4.0 a rewritten WYSIWYG editor, that stores as source XHTML, not any more wiki markup.
Leads to an update of all pages when migrating.
Was pretty difficult to implement. I do not know if they use any more the TinyMCE editor of previous versions.
Follow the format of markdown how to include images in your source format. So by typing: This is my text. !image.png! The inline image shows ..., you will have a format that is understandable.
You have to expand the interpretation, so that the !<filename>! will be mapped that is stored locally anyway.
You have to add clear-up dialogs for the images that are yet not known, so doing bulk uploads ...
You may provide a drag area on your view, that then shows the filename and gives examples how to include that inside the text area.
Go for something in between, by allowing users to drag images inside the editor. There are plugins written in Javascript that allow you to do that, e.g. UI Draggable for jquery
I have no idea how to integrate that image inside the text editor. Overlay?
So the second one is the easiest, and the user knows how to do it. If they only decide that this is the solution they want to have :-)
I think I'm going to use a combination of #2 above, and the Liquid templating engine.

How Can I Automatically Execute A Link In Internet Explorer

I am trying to create an application to print documents over the web. I have created my document, and made a web page with a meta refresh tag, along the lines of this:
<meta http-equiv="refresh" content="3;http://example.com/download.epl2" />
I specify that the document has a content-type of application/x-epl2, and I have associated .epl2 files on my computer with a program that silently sends them to the printer.
I have put the website into my trusted sites zone.
Currently Internet Explorer pops up the "Open, Save, Cancel" dialog box with no option to automatically open the file.
Is there a setting in IE6/7/8 that I can use to have IE just open the file without prompting?
EDIT
The actual content of the file will differ based on the job, but essentially it is text that follows the Eltron Programming Language.
EDIT
I have accomplished this in both Chrome and Firefox by choosing "Automatically Open Files Of This Type From Now On"
EDIT
The machines this program will be used on will effectively be kiosks that are limited to only accessing my website from their web browsers, so I'm not worried about rogue websites sending documents to my printers.
EDIT
I am using PHP to generate the documents and HTML on the server side, though I expect the solution to be language agnostic.
I would expect that not to be possible, because then you could stumble onto a site that automatically loads and prints a 5000 page document or something, which would not be good.
If you always had a secret desire to develop a custom URL protocol (I know I do), this might be a good excuse to do it. ;-)

There are 1-2 prompts when opening such a link for the first time in IE, but you can choose to automatically open them after that.
I would use javascript to make this happen.
Javascript Window Open
EDIT
Since you have control of the windows box you could use an automate script process to interact with the print window.
autoit3: ControlClick
Write a small utility program that does nothing but send the file passed to it on the command-line to the default system printer.
Then, edit the registry under HKEY_CLASSES_ROOT to associate this program with the .epl2 filetype.
I don't have time to investigate it for You, but there were lots of exploits that could be helpful. Using ie6 without certain fixes seems helpful.
Also there should be an option called "Automatic prompting for file downloads". I use Linux nowadays so I can't chceck if it helps. I found it in some docs.
I'm on a Mac at the moment, but if this is possible in IE I would imagine this page holds the answer to it (or at least hints at it) http://support.microsoft.com/kb/883255
I believe what you're looking for is a setting in Windows, not IE:
Microsoft Support: Not Prompted to Specify Download Folder for File
Try using an older version of IE. Security was looser in the older versions and since it's a non-issue, this could be the quickest solution.
