Stаcking Window Manager
A stacking window manager is a window manager that draws all windows in a specific order, allowing them to overlap, using a technique called painter's algorithm. All window managers which allow the overlapping of windows, but are not compositing window managers are considered stacking window managers, although it is possible that not all use exactly the same methodologies. Other window managers that are not considered stacking window managers are those that do not allow the overlapping of windows. These are called tiling window managers.
Stacking window managers allow windows to overlap by drawing them one at a time. Stacking, or repainting (in reference to painter's algorithm) refers to the rendering of each window as an image, painted directly over the desktop, and over any other windows that might already have been drawn, effectively erasing the areas that are covered. The process usually starts with the desktop, and proceeds by drawing each window and any child windows from back to front, until finally the foreground window is drawn.
The order in which windows are to be stacked is called their z-order.
Famous quotes containing the words manager and/or window:
“I knew a gentleman who was so good a manager of his time that he would not even lose that small portion of it which the calls of nature obliged him to pass in the necessary-house, but gradually went through all the Latin poets in those moments. He bought, for example, a common edition of Horace, of which he tore off gradually a couple of pages, read them first, and then sent them down as a sacrifice to Cloacina: this was so much time fairly gained.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (16941773)
“It is a pleasure to stand upon the shore, and to see ships tossed upon the sea: a pleasure to stand in the window of a castle, and to see a battle and the adventures thereof below: but no pleasure is comparable to standing upon the vantage ground of truth ... and to see the errors, and wanderings, and mists, and tempests, in the vale below.”
—Francis Bacon (15611626)
