To do this, add a search element in the form attribute in the search element. Also, it is possible to send CGI parameters and post data at the same time -- to do this, use two question mark '? This example uses a post method to send postdata (highlighted): The download URL you use to host the XML file for the button becomes the button's unique ID for updating the button.
If a second attempt is made to download a button from the same URL, the toolbar will offer only to replace the old one, not add a new one.
Windows XP allows users to customize their color scheme, including toolbar backgrounds.
You could get around this by making a square icon that doesn't have any transparent parts, but they don't look as interesting.
Besides sending the search query, you can also specify the current URL the browser displays three different ways: You can also allow a custom button to send a piece of plain text that might be selected on the web page by the user.
This could be useful for a translation service, or maybe a blogging or messaging application.
Of the five ways to add a button, the first and last ways automatically know where the button updates should come from, and any tag that the user can easily change in the toolbar settings dialog box. Use the variable inside of any url template specification to insert the user's text.
This is useful, for example, in the case of a weather button to specify a zip code or a stock button to specifiy a ticker symbol. There is no validating or whitespace trimming of the input at this time, and the variable will escape whatever the user typed in using charset encoding (utf-8) and cgi parameter escaping, just as a text edit box on a form submit would.
Here is an example of a mood ring button that pulls from a feed: AAAAAAMAAAABAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACAAAAAw AAAAMAA AAABAAEAEBAAAAEAIABo BAAAFg AAACg AAAAQAAAAIAAAAAEAIAAAAAAAQAQAAAAAAAAAAAAAAAAA AAAAAAAAAAAGAAAAHAAAAEAAAABh AAAAcw AAAHQAAABp AAAAVQAAAD4AAAAp AAAAGAAAAAo AAAAD AAAAAQAAAAAAAAAAAAAAESZIXl4zd Jv AXb HS8m3C3f9Lnrr LFUtsmw ILEX4AAABz AAAAYQAAAEc A AAAq AAAAEw AAAAc AAAACAAAAACs9RTNOjr Dt W6n S/53u/f n/P//hej//2b P/P9Fq93w HGa Nrx Ev O4k AAAB6AAAAXw AAADw AAAAf AAAADAAAAANiha WST6XK/0h/kc Ad KCy WKTt Ag VJ/k Ihyt NKse873 9E w6v9Ru N39SXu Jpg QHCIo AAAB2AAAAUQAAACs AAAAPb6n U7m K65v9jqs76Kk NPq AUICJo AAACE AAAAax Ug JWBkr Miwsvv //D /v y1Nni Ij1Fn AAAAIg AAABc AAAALHS74PV1z Pn/c835/1Oezv9N iq7v NVRjrx Ui J5k BAg ORAQICh3u Lj Zz3 vr1 f///4PL5/wv Vmus AAAAig AAAFNyu TPdt L8/0Cp 7v8ng8X/CFOH/ytpjv86g J//R46z Th6jsov Vm Csd56px Nf2/f9Tu PH/W7fs/yp GV6UAAAByf77Y r02y7P9Zwfb/pu H3/y At P8j Z5f/KWKH/0p7h P Zr Vr/zc Ut/9v MKf/bz Sz/ts BP/3Ozr P9kl7Pp AAAAg HGdp Thatu T/0fn //b/// V0uv/NICu/4mvf P/czj L/3M0v/9r MKP/dzz T/3c83/9v NLf/b z S//nr WA/g AAAIMAMz MFbrrd2d/ ///5////t n6/4q6nf/czz X/3t A /97QPf/czj P/3d A7/97R Qv/czj D/3M4z/9DHLPo AAAB/AAAAAWSht Uix5 //5v7 /5Hf7//Bvjn/3M0v/9/SSP/g1FL/39RR / DVWv/e0kf/3t FA/9z NL//bz Cj/AAAAbw AAAAAAAAADcq7Fmpzo8f9rs L3/2ssl/93POf/f0kj/ 49pu/ ffh P/q45b/49pp/97SSv/cz S//yb0q4w AAAE8AAAAAAAAAAF54hh Nrq77BXp Cj/7 7Of/c zj H/3t FH/ bde P/w7cv/9PLa/ zlnf/g1VP/1so5/m Bf JHs AAAAr AAAAAAAAAAAAAAABa5Gg IHWs t/dym G3/3t E//9/UUv/o4Ij/9PHT//v67P/v6a3/08x Y/3u MX6UAAAAu AAAAEAAAAAAAAAAAAAAA AAAAAAKSvb9YSo Wa Wyag P wv2X/4NRO/ ngfv/m4Zf/r Le B lpub Ik AAAAl AAAADg AAAAMAAAAA AAAAAAAAAAAAAAAAAAAAAoqvu Dxkkp2g Yo c51m Hkv9lk5v/Y4e Ntl Bfa Eg AAAAWAAAACQAAAAIA AAAAAAMAAAABAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACAAAAAw AAAAMAA AADg AAAA8AEAAA== The icons should be in the same folder as the script.
You can also add custom server-based icons to the individual items on the feed dropdown menu.
Single color alpha channels, like GIF images, will have grainy-looking rounded exterior edges compared to a properly built alpha-blended icon, such as the ones on the Google Toolbar or Internet Explorer itself.
