This suggestion concerns implementing a method in html to incorporate transient windows, such as may be produced with Java. I've been sitting on this for a while, hoping to work this idea out a little more. I haven't been able to due to lack of space-time. So here it is, raw & unprettied. This idea came to me while working on an intranet site for engineering info. I found that I needed transient windows for certain documents which included drawings and images (actually, the documents _were_ drawings & images) which were rather large in size to let users see information about parts of the image without having to move between documents. It is supposed to make it easier for the user to work with. The idea was conceived before Java, based at the time on the little popup windows that one may see in a Windows app when the mouse pointer is moved over a function button and also based on the transient windows used in the Windows Help facility where a small textbox appears when certain tags within a help document are clicked. While it is possible to do the same thing with Java, not everyone can play with Java (me included)--or perhaps not permitted to ([@$%&*!!!]company policies!). So it would be useful to have it as part of html and not some add-on. It can use some improvements: There could be an "onmouseover" action and some other options, as well, for example. Please note that this is a rather raw "brainstorm" and not an attempt at a formal specification. -- Don't read Spam! EAT IT!

Can be used to replace separate definitions page. Can be used to provide dynamic data about a graphic. (ie, a commercial page displaying product images--popups can provide pricing and availability info without having to move user to a different page) Useful for speeding up http transfers? No need to send a whole document... Reduces cache sizes? Two kinds: 1. Embedded 2. Subdocument A transient window is a small window that pops up when it's link within a document is selected. It contains either static or dynamic data. Static data is data embedded within a transient window tag in a HTML document. Dynamic data is data returned by the server when it's link is selected in a subdocument known as a "popup". Embedding a transient window with static data: The data to be displayed in a transient window is enclosed within the <POPUP> </POPUP> tags A browser that is capable of recognizing the <POPUP> tags should hide the contents of the embedded tag until it is selected then overlay a small window on the current document without changing it. A browser which does not recognize the tags should hopefully ignore the unrecognized tag and display the tag contents normally inline. Using a subdocument for a transient window: A transient window may contain a subdocument known as a "transient document". A "transient subdocument" is a HTML document with an additional option within the HTML tag to specify that it is not a normal subdocument, e.g., "<HTML "TRANSIENT">" or "<HTML "POPUP">. A browser capable of recognizing the "TRANSIENT" or "POPUP" options should display a small window which may overlay the current document with the contents of the subdocument without changing the current document. A browser that does not recognize the "TRANSIENT" or "POPUP" options should display the document as if it were a normal HTML document. The transient window may be dismissed or closed by explicit or implicit means: 1. Explicitly by clicking within the window (not recommended if links are to be permitted within transient windows) or on a "Dismiss" or "Close" button within the window (preferred). 2. Implicitly by clicking anywhere within the browser's window, including within the popup window. To tell the browser which action should be required to close a transient window, an option should be added to the <POPUP> tag: <POPUP="IMPLICIT">, etc. The default action should be to require explicit dismissal. [More dismiss options: A dismiss button option...] For a subdocument, this method is suggested: <HTML "TRANSIENT=IMPLICIT"> Again, the explicit dismissal method should be the default. A transient window should be smaller than the browser window. The maximum size should be limited to less than 60 percent of the browser window size. A transient window should be contained within a frame boundary and never cross another frame. Exception: If the frame is too small to contain the window, it may be placed over another frame but adjacent to it's own frame. Perhaps a line can attach the popup with it's parent frame? A transient window subdocument should have all other options permitted for regular documents such as background color or image, font colors, images, et cetera. A transient window must close when it's parent is no longer displayed, i.e., when user moves to another document. except... Could a transient window be "nailed down" by user? Might be useful if user needs to keep it for a while. If so, it should stay until explicitly dismissed by user, even when user moves to another document. Accomodating the future: For HTML, declare a subdocument type with the "SUBDOCUMENT" option. For example, to declare a HTML document as a transient window subtype: "<HTML SUBDOCUMENT="TRANSIENT,IMPLICIT">. This will allow easier additions of new document subtypes in the future. <POPUP> CLOSE= "EXPLICIT" "IMPLICIT" "BUTTON" </POPUP> <HTML> SUBDOCUMENT= "TRANSIENT, CLOSE= EXPLICIT" IMPLICIT" BACKGROUND= BGCOLOR= FONTCOLOR= FONT= </HTML ==END== -- Don't read Spam!
