How To Download On Window 10

The Window interface is home to a variety of functions, namespaces, objects, and constructors which are not necessarily directly associated with the concept of a user interface window. However, the Window interface is a suitable place to include these items that need to be globally available. Many of these are documented in the JavaScript Reference and the DOM Reference.

In a tabbed browser, each tab is represented by its own Window object; the global window seen by JavaScript code running within a given tab always represents the tab in which the code is running. That said, even in a tabbed browser, some properties and methods still apply to the overall window that contains the tab, such as resizeTo() and innerHeight. Generally, anything that can't reasonably pertain to a tab pertains to the window instead.

Returns the horizontal (X) coordinate of the top-left corner of the window's viewport, in screen coordinates. This value is reported in CSS pixels. See mozScreenPixelsPerCSSPixel in nsIDOMWindowUtils for a conversion factor to adapt to screen pixels if needed.

Returns the vertical (Y) coordinate of the top-left corner of the window's viewport, in screen coordinates. This value is reported in CSS pixels. See mozScreenPixelsPerCSSPixel for a conversion factor to adapt to screen pixels if needed.

Listen to these events using addEventListener() or by assigning an event listener to the oneventname property of this interface. In addition to the events listed below, many events can bubble from the Document contained in the window object.

A window is an opening in a wall, door, roof, or vehicle that allows the exchange of light and may also allow the passage of sound and sometimes air. Modern windows are usually glazed or covered in some other transparent or translucent material, a sash set in a frame[1] in the opening; the sash and frame are also referred to as a window.[2] Many glazed windows may be opened, to allow ventilation, or closed, to exclude inclement weather. Windows may have a latch or similar mechanism to lock the window shut or to hold it open by various amounts.

In addition to this, many modern day windows may have a window screen or mesh, often made of aluminum or fibreglass, to keep bugs out when the window is opened. Windows are primarily designed to facilitate a vital connection with the outdoors, offering those within the confines of the building visual access to the everchanging events occurring outside. The provision of this connection serves as an integral safeguard for the health and well-being of those inhabiting buildings, lest they experience the detrimental effects of enclosed buildings devoid of windows. Among the myriad criteria for the design of windows, several pivotal criteria have emerged in daylight standards: location, time, weather, nature, and people. Of these criteria, windows that are designed to provide views of nature are considered to be the most important by people.[3]

Types include the eyebrow window, fixed windows, hexagonal windows, single-hung, and double-hung sash windows, horizontal sliding sash windows, casement windows, awning windows, hopper windows, tilt, and slide windows (often door-sized), tilt and turn windows, transom windows, sidelight windows, jalousie or louvered windows, clerestory windows, lancet windows, skylights, roof windows, roof lanterns, bay windows, oriel windows, thermal, or Diocletian, windows, picture windows, Rose windows, emergency exit windows, stained glass windows, French windows, panel windows, double/triple-paned windows, and witch windows.

The English language-word window originates from the Old Norse vindauga, from vindr 'wind' and auga 'eye'.[4] In Norwegian, Nynorsk, and Icelandic, the Old Norse form has survived to this day (in Icelandic only as a less used word for a type of small open "window", not strictly a synonym for gluggi, the Icelandic word for 'window'[5]). In Swedish, the word vindga remains as a term for a hole through the roof of a hut, and in the Danish language vindue and Norwegian Bokml vindu, the direct link to eye is lost, just as for window. The Danish (but not the Bokml) word is pronounced fairly similarly to window.

Window is first recorded in the early 13th century, and originally referred to an unglazed hole in a roof. Window replaced the Old English eagyrl, which literally means 'eye-hole', and eagduru 'eye-door'. Many Germanic languages, however, adopted the Latin word fenestra to describe a window with glass, such as standard Swedish fnster, or German Fenster. The use of window in English is probably because of the Scandinavian influence on the English language by means of loanwords during the Viking Age. In English, the word fenester was used as a parallel until the mid-18th century. Fenestration is still used to describe the arrangement of windows within a faade, as well as defenestration, meaning 'to throw out of a window'.

In the 13th century BC, the earliest windows were unglazed openings in a roof to admit light during the day.[citation needed] Later,[when?] windows were covered with animal hide, cloth, or wood. Shutters that could be opened and closed came next.[when?] Over time, windows were built that both protected the inhabitants from the elements and transmitted light, using multiple small pieces of translucent material, such as flattened pieces of translucent animal horn, paper sheets, thin slices of marble (such as fengite), or pieces of glass, set in frameworks of wood, iron or lead. In the Far East, paper was used to fill windows.[1]The Romans were the first known users of glass for windows, exploiting a technology likely first developed in Roman Egypt. Specifically, in Alexandria c. 100 CE, cast-glass windows, albeit with poor optical properties, began to appear, but these were small thick productions, little more than blown-glass jars (cylindrical shapes) flattened out into sheets with circular striation patterns throughout. It would be over a millennium before window glass became transparent enough to see through clearly, as we expect now. In 1154, Al-Idrisi described glass windows as a feature of the palace belonging to the king of the Ghana Empire.[6][7]

Over the centuries techniques were developed to shear through one side of a blown glass cylinder and produce thinner rectangular window panes from the same amount of glass material. This gave rise to tall narrow windows, usually separated by a vertical support called a mullion. Mullioned glass windows were the windows of choice[when?] among the European well-to-do, whereas paper windows were economical and widely used in ancient China, Korea, and Japan. In England, glass became common in the windows of ordinary homes only in the early-17th century, whereas windows made up of panes of flattened animal horn were used as early as the 14th century.[8]

Modern-style floor-to-ceiling windows became possible only after the industrial plate glass-making processes were perfected.[when?] Modern windows are usually filled using glass, although a few are transparent plastic.[1]

The introduction of lancet windows into Western European church architecture from the 12th century CE built on a tradition of arched windows [9] inserted between columns,[10] and led not only to tracery and elaborate stained-glass windows but also to a long-standing motif of pointed or rounded window-shapes in ecclesiastical buildings, still seen in many churches today.

Up to about 1680 windows tended to be horizontal in proportion, a shape suitable for lighting the low-ceilinged rooms that had resulted from the insertion of the upper floor into the hall-house. After that date vertically proportioned windows came into fashion, partly at least as a response to the Renaissance taste for the high ceiling. Since 1914 the wheel has come full circle and a horizontally proportioned window is again favoured.[11]

The term eyebrow window is used in two ways: a curved top window in a wall or an eyebrow dormer; and a row of small windows usually under the front eaves such as the James-Lorah House in Pennsylvania.[14]

A fixed window is a window that cannot be opened,[15] whose function is limited to allowing light to enter (unlike an unfixed window, which can open and close). Clerestory windows in church architecture are often fixed. Transom windows may be fixed or operable. This type of window is used in situations where light or vision alone is needed as no ventilation is possible in such windows without the use of trickle vents or overglass vents. ff782bc1db
