示例1: onDetach
# 需要导入模块: from pyjamas import DOM [as 别名]
# 或者: from pyjamas.DOM import setEventListener [as 别名]
def onDetach(self):
"""Called when this widget is being removed from the DOM tree of the document."""
if not self.isAttached():
return
self.doDetachChildren()
self.attached = False
DOM.setEventListener(self.getElement(), None)示例2: onAttach
# 需要导入模块: from pyjamas import DOM [as 别名]
# 或者: from pyjamas.DOM import setEventListener [as 别名]
def onAttach(self):
"""Called when this widget has an element, and that element is on the document's
DOM tree, and we have a parent widget."""
if self.isAttached():
return
self.attached = True
DOM.setEventListener(self.getElement(), self)
self.doAttachChildren()
self.onLoad()示例3: prepareImage
# 需要导入模块: from pyjamas import DOM [as 别名]
# 或者: from pyjamas.DOM import setEventListener [as 别名]
def prepareImage(self, url):
img = Image()
img.__isLoaded = False
img.addLoadListener(self)
# normally, event listeners are only set up when the widget
# is attached to part of the DOM (see Widget.onAttach). but,
# in this case, we want a load even _even though_ the Image
# widget is not yet attached (and quite likely won't be).
DOM.setEventListener(img.getElement(), img)
