Window:onClose() event
This event is fired when the window is about to be closed (when the user has clicked on the window close button).
Return value
This event returns true if the application actually wants to close the window or false otherwise (and the window will remain open).Example
local ui = require "ui"
-- create a window that never closes !
local win = ui.Window("Window:onClose() sample", 320, 200)
-- set a onClose() event : returns false to prevent the window to close
function win:onClose()
return false
end
win:show()
while win.visible do
ui.update()
end
