    proc popup_window { win {title "Popup Window"} {
        toplevel $win -borderwidth 10 -width 600 -height 400
        wm title $win $title
        text $win.text
        pack $win.text -fill both
    }
    
    popup_window .test_popup "Hello World"
    
    

    最大化弹出窗口

    proc maximize_toplevel {
        if {([catch {package present Tk 8.3}] == 0) &&
            [string equal $::tcl_platform(platform) windows]} {
             wm state $toplevel zoomed
             return
         }
         pack propagate $toplevel 0
         update idletasks
         wm geometry $toplevel +0+0
         wm minsize $toplevel [winfo screenwidth $toplevel] [winfo screenheight $toplevel]
    }

    set w .dlg
    
    toplevel $w   ; # 创建对话框, ...
    
    # 限制事件的发生范围
