.on_layout_change(&block) ⇒ Object

Register for notifications on layout change. The given block will be called whenever the layout changes - this could be due to making an app fullscreen, changing a space name, or changing the layout of the TotalSpaces2 grid. There are no arguments passed to the block.

TotalSpaces2.on_layout_change {puts "Spaces changed"}

sleep

When you get a notification from this method, you should re-fetch any information about the spaces that you may be storing.

There can only be one block registered at any time, the most recently registered one will be called.

  TSApi.tsapi_setLayoutChangedCallback(block)
end

.on_space_change(&block) ⇒ Object

Register for notifications on space change. The given block will be called whenever you move from one space to another. The arguments are the space number you moved from, and the one you are moving to.

TotalSpaces2.on_space_change {|from, to, displayID| puts "Moving from space #{from} to space #{to}"}

sleep

There can only be one block registered at any time, the most recently registered one will be called. This callback is called just before the space actually changes - current_space will still report the from space.

Any windows present on a desktop being removed will be moved to one of the remaining desktops. Returns true on success, false if number_to_remove was zero or would result in less than 1 desktop remaining. The on_layout_change notification will be sent if a change was made.

.set_grid_columns(columns) ⇒ Object

Sets the number of columns defined in TotalSpaces2 for the main display.

.window_listObject

Get a list of all the windows on your mac It returns an array containing a hash for each window. The hash contains the display id (key :display_id) and space number (key :space_number) and details for each window. The windows are in front to back order within each space. Each window hash also contains a window_id, title, frame, app_name and is_on_all_spaces flag

The below example would move the frontmost window to the next space to the right.

windows = TotalSpaces2.window_list
current_space = TotalSpaces2.current_space
main_display_id = TotalSpaces2.main_display[:display_id]
if !windows.empty?
  current_space_windows = windows.select {|window| window[:display_id] == main_display_id
