Execute the given block every interval milliseconds and return a timer object. Note that if the timer is garbage collected, the block will not be executed anymore, so the caller should keep a reference to it for as long as needed. To prevent further invocations of the block, use QTimer#stop.
# File lib/rui/toolkits/qtbase/qt.rb, line 341 def self.every(interval, &blk) time = Qt::Time.new time.restart timer = new timer.connect(SIGNAL('timeout()')) { blk[time.elapsed] } timer.start(interval) # return the timer, so that the caller # has a chance to keep it referenced, so # that it is not garbage collected timer end
in(interval, target = nil, &blk)

Execute the given block after interval milliseconds. If target is specified, the block is invoked in the context of target.
# File lib/rui/toolkits/qtbase/qt.rb, line 358 def self.in(interval, target = nil, &blk) single_shot(interval, Qt::BlockInvocation.new(target, blk, 'invoke()'), SLOT('invoke()')) end
