How can I do the same for the maximize button of the window?

推荐答案

它没有标准协议，无论是在 X11 ICCCM 集 或 FreeDesktop 套装.因此，wm 协议 不可能用于它.但是，您可以使用 事件来跟踪窗口的所有大小更改.请注意，如果您将其设置在顶层，您还将收到该窗口内所有小部件的通知，因此您应该在对其采取行动之前检查该事件是否真的与顶层有关，可能如下所示:

There's no standard protocol for it, either among the X11 ICCCM set or the FreeDesktop set. As such, wm protocol cannot possibly be used for it. However, you can use the <Configure> event to track all size changes for a window. Note that if you set it on a toplevel, you will also get notifications for all widgets inside that window, so you should check to see if the event was really about the toplevel before acting on it, perhaps like this:

bind $toplvl <Configure> {
    if {"%W" eq [winfo toplevel "%W"]} {
        ActOnResize %W %w %h [wm attributes %W -zoomed]
    }
}

您可能还想检查 -fullscreen 属性.

You might also want to check the -fullscreen attribute.
