Perl TK bind事件

如何用bind绑定控件按下回车触发事件

wand65

cmd-> perldoc Tk::bind

Jack_Tan123

tk窗口置顶有这项属性吗？

为什么$mw->bind("<Enter>"=>sub);这样写不会触发enter事件呢

你指的是不是下面的东东

The deiconify method causes the Toplevel to be displayed noniconified or deiconifies it immediately if the window has already been displayed once. If the window has been withdrawn, a $toplevel->raise( ) must also be done to display the window correctly.

If you call it with no arguments, the raise method brings the Toplevel to the front of all the other Toplevel windows in the application:

$toplevel->raise( );
You can also put the Toplevel in front of another Toplevel:

$toplevel->raise($other_toplevel);
It is sometimes necessary to use both deiconify and raise to get the window to show up on the screen.

不是，是窗口置顶，整个窗口在系统的最顶端
