原文:WPF中获取TreeView以及ListView获取其本身滚动条的方法,可实现自行调节scoll滚动的位置(可相应获取任何控件中的内部滚动条) 对于TreeView而言: TreeViewAutomationPeer lvap = new TreeViewAutomationPeer(treeView); var svap = lvap.GetPattern(PatternInterface.Scroll) as ScrollViewerAutomationPeer; var scroll

1.循环遍历数组是,想添加条件修改时,只删除第一个 # -*- coding: utf-8 -*- a=[11,22,33,44,55] for i in a: if i == 11 or i ==22: a.remove(i) for i in a: print(i) ''' 22 33 44 55 [Finished in 0.1s] ''' 2.应该引入被删除为一个数组 # -*- coding: utf-8 -*- a=[11,22,33,44,55] b=[] for i in a:
