如何将垂直滚动条Scrollbar一直自动滚在下面比如用滚动条看一个text 我写进去一些东西滚动条自动向下滚而不用我手动的按向下帮助文档里看了看好像是可以的就是没看得太懂 SCROLLING COMMANDS When the user interacts with the scrollbar, for example by dragging the slider, the scrollbar notifies the associated widget that it must change its view. The scrollbar makes the notification by evaluating a callback specified as the scrollbar's -command option. The callback may take several forms. In each case, the intial arguments passed are those specified in the -command callback itself, which usually has a form like [yview => $widget]. (Which will invoke $widget->yview(...) where the ... part is as below. See the Tk::callbacks manpage for details.) The callback is passed additional arguments as follows: scroll,number,units The widget should adjust its view by number units. The units are defined in whatever way makes sense for the widget, such as characters or lines in a text widget. Number is either 1, which means one unit should scroll off the top or left of the window, or -1, which means that one unit should scroll off the bottom or right of the window. 有谁能举段代码的例子吗多谢

你的问题我没有看的很明白.它本来就是自动下滚的. #!/usr/bin/perl use Tk; $mw=new MainWindow; $text=$mw->Scrolled(Text,-scrollbars,'osoe'); $text->pack(-anchor,'nw'); MainLoop;
