Tile windows

The tileWindows function in this module is primarily meant for use by hs.window.layout; however you can call it manually (e.g. for your custom layout engine).

Signature hs.window.tiling.tileWindows(windows,rect[,desiredAspect[,processInOrder[,preserveRelativeArea[,animationDuration]]]])
Type Function
Description Tile (or fit) windows into a rect
Parameters
  • windows - a list of hs.window objects indicating the windows to tile or fit
  • rect - an hs.geometry rect (or constructor argument), indicating the desired onscreen region that the windows will be tiled within
  • desiredAspect - (optional) an hs.geometry size (or constructor argument) or a number, indicating the desired optimal aspect ratio (width/height) of the tiled windows; the tiling engine will decide how to subdivide the rect among windows by trying to maintain every window's aspect ratio as close as possible to this; if omitted, defaults to 1 (i.e. try to keep the windows as close to square as possible)
  • processInOrder - (optional) if true, windows will be placed left-to-right and top-to-bottom following the list order in windows; if false or omitted, the tiling engine will try to maintain the spatial distribution of windows, i.e. (roughly speaking) pick the closest window for each destination "tile"; note that in some cases this isn't possible and the windows might get "reshuffled" around in unexpected ways
  • preserveRelativeArea - (optional) if true, preserve the relative area among windows; that is, if window A is currently twice as large as window B, the same will be true after both windows have been processed and placed into the rect; if false or omitted, all windows will have the same area (= area of the rect / number of windows) after processing
  • animationDuration - (optional) the number of seconds to animate the move/resize operations of the windows; if omitted, defaults to the value of hs.window.animationDuration
Returns
  • None
Notes
  • To ensure all windows are placed in a row (side by side), use a very small aspect ratio (for "tall and narrow" windows) like 0.01;
  • similarly, to have all windows in a column, use a very large aspect ratio (for "short and wide") like 100
  • Hidden and minimized windows will be processed as well: the rect will have "gaps" where the invisible windows
  • would lie, that will get filled as the windows get unhidden/unminimized
