Displaying Places information using views
views are one component of the places model-view-controller design. use them to display nsinavhistoryresult objects to the user. see querying places for information about obtaining and using nsinavhistoryresult objects, which this page assumes you are familiar with. an nsinavhistoryresult instance provides the data for a view. the view is responsible for expanding the root nsinavhistorycontainerresultnode of this instance and displaying the nsinavhistoryresultnode objects contained therein. the built-in views if you need to show the contents of bookmarks or history in your extension or application, you may want to use the built-in places views, which are generic and will save you a lot of time writing basic functionality so that you can focus on building your extension or applicat...

Querying Places
executing a query places queries have several basic parts: the query object: nsinavhistoryquery, holds the search parameters the query options: nsinavhistoryqueryoptions, allows configuration of the search result the history service: nsinavhistoryservice, executes the query the first first step is to create the query and options, and fill them with the parameters you want. use nsinavhistoryservice.getnewquery() and nsinavhistoryservice.getnewqueryoptions() to retrieve empty objects. the defaults for these objects will result in a query that returns all of your browser history in a flat list: chromeutils.definemodulegetter(this, "placesutils", "resource://gre/modules/placesutils.jsm"); // no query options set will get all history, sorted in dat...

Sizing items in CSS - Learn web development
cause your site to become slow, and it can cost users more money if they are on a metered connection. note: find out more about responsive image techniques. viewport units the viewport — which is the visible area of your page in the browser you are using to view a site — also has a size. in css we have units which relate to the size of the viewport — the vw unit for viewport width, and vh for viewport height. using these units you can size something relative to the viewport of the user. 1vh is equal to 1% of the viewport height, and 1vw is equal to 1% of the viewport width. you can use these units to size boxes, but also text. in the example below we have a box which is sized as 20vh and 20vw. the box contains a letter a, which has been given a font-size of 10vh. if you change...
...viewport height. using these units you can size something relative to the viewport of the user. 1vh is equal to 1% of the viewport height, and 1vw is equal to 1% of the viewport width. you can use these units to size boxes, but also text. in the example below we have a box which is sized as 20vh and 20vw. the box contains a letter a, which has been given a font-size of 10vh. if you change the vh and vw values this will change the size of the box or font; changing the viewport size will also change their sizes because they are sized relative to the viewport. to see the example change when you change the viewport size you will need to load the example in a new browser window that you can resize (as the embedded <iframe> that contains the example shown above is its viewport). open the examp...
...hat you can resize (as the embedded <iframe> that contains the example shown above is its viewport). open the example, resize the browser window, and observe what happens to the size of the box and text. sizing things according to the viewport can be useful in your designs. for example, if you want a full-page hero section to show before the rest of your content, making that part of your page 100vh high will push the rest of the content below the viewport, meaning that it will only appear once the document is scrolled. test your skills! we have covered a lot in this article, but can you remember the most important information? you can find some further tests to verify that you've retained this information before you move on — see test your skills: sizing. summary this lesson has given...

History Service Design
cument provides a high-level overview of the overall history service design of the places system. places is designed to be a complete replacement for the firefox bookmarks and history systems using storage. this system provides additional performance, flexibility, and querying capabilities over the old one, for both end users and extensions developers. view the service interface definition: nsinavhistoryservice.idl. objectives the primary objectives of the new history service implementation in places are: improve access to browsing history allow association of useful metadata with urls flexible query system for both end-users and add-ons developers clean architecture for ease of code reuse and maintainability the most known and visible feature of history are views. the user can qu...
...mmon interface. long term objectives include the ability to index more informations from the visited pages, through fulltext indexes, and the possibility to generalize the frecency algorithm to allow for its use in user's queries. might be also nice to provide a hook for third-party products so they can provide text searching capabilities to the places system. places core history service (nsinavhistoryservice.idl) is the core of places, every other places service depends on it to correctly work, so it gets always initialized at application startup. actual tasks executed by this service include: database creation, maintenance and initialization: all services rely on a common shared database called places.sqlite. history service checks for database existance and coherence, and initia...
...the moment this is used when catching favicons or bookmarks for redirected pages. querying for data querying data is a basic feature for places. thanks to the underlying database, history size has increased far more than 10 times from the previous mork based implementation, thus the need for a simple and efficient way to extract slices of data. a places query is made of of a query object (nsinavhistoryquery) and a query options object (nsinavhistoryqueryoptions) that defines the constraints results must obey to. these objects can be directly instantiated and built, setting their attributes, but places allows a more readable and manageable form for queries: place query uris. query uris (for example place:querytype=0&sort=8&maxresults=10) can be easily built and read by users (through a bui...

Using the Places favicon service
s sure that we aren't obsessively reloading favicons into the database for every page viewed, but also that changes in the favicon will be picked up quickly. most of the time, the favicon will be served from the browser's cache and will have minimal performance impact. this expiration time is not the time that the favicon will be deleted. expiration is handled by browser/components/places/src/nsnavhistoryexpire.cpp as described in places design. the expiration time is only used to determine whether data should be reloaded from the network (or cache) or whether the version in the database is fresh enough. getting favicon images you can use favicons in the browser ui using special annotation uris. nsifaviconservice.getfaviconimageforpage() returns an annotation uri for the favicon for a giv...

ging) transaction. that is not needed now. you can control the size of the memory cache using the cache_size pragma. this value controls the number of pages of the file that can be kept in memory at once. the page size can be set using the page_size pragma before any operations have been done on the file. you can see an example of setting the maximum cache size to be a percentage of memory in nsnavhistory::initdb in toolkit/components/places/src/nsnavhistory.cpp. sharding the cache between connections by default, storage enables the sqlite shared-cache mode which makes multiple connections to the same database share the same cache. the cache is threadsafe. all you need to do is use services.storage.opendatabase(file). some features (virtual tables, full text indexes) are not compatible with ...

Finding the code for a feature
look for "cmd_tag". i see it occurs in mail3panewindowcommands.js a couple of times. i look at the last occurrence, and see it is just an enable item with no real action involved. oops, i guess i need to get the submenu instead. repeating this process, i see that the submenu items all call a function togglemessagetagmenu. looking that up in mxr, its underlying function uses a very strange call prevhdrfolder[toggler](messages, key) to change the key. trying to figure that out from the code, i see that is just a clever way to do the addkeywordstomessages or removekeywordsfrommessages method call. (please don't do that guys, it really makes code search difficult!) so the answer the your question is, use the nsimsgfolder method "addkeywordstomessages" (and now i remember that i knew that!). if...
