删除网格 Tkinter 中的某些行/列 [英] Deleting certain rows/columns in a grid Tkinter

问题描述

如果我在 SAME 框架中有多个行和列以及多个条目/标签小部件，是否可以只选择其中一个并删除它，同时保留其他小部件.

If I have several rows and columns with several entry/label widgets in the SAME frame, is it possible to choose just a single one of them and delete it whilst leaving the others alone.

例如

class Window():
    def __init__(self):
        self.root = Tk()
        self.win1 = Frame(self.root)
        entry1 = Entry(win1, row=1, column=1)
        entry2 = Entry(win1, row=1, column=2)
        label1 = Label(win1, row=1, column=3)

    def main1(self):
        label2 = Label(win1, row=1, column=4)
        labeln = Label(win1, row=1, column=n)

然后我想从第 3 列开始删除，其中 n 可能是一个随机数.是否可以获取 grid_forget 并插入列数?行也可以吗?

I would then like to remove from column 3 onwards, where n could be a random number. Is it possible to get grid_forget and insert the number of columns? Is it also possible for the rows as well?

更新:或者是否可以简单地返回在init下创建的窗口并删除在main1下创建的那些(但已在同一框架中创建)?

UPDATE: OR is it possible to simply return back to the window created under init and delete those created under main1 (but have been created in the same frame)?

谢谢.

推荐答案

阅读 grid_remove 和 grid_forget 方法；这些将允许您从视图中删除现有的小部件.您还可以销毁小部件，使它们消失.

Read up on the grid_remove and grid_forget methods; these will alow you to remove existing widgets from view. You can also destroy widgets, causing them to vanish.

我已经有一段时间没有这样做了(并且目前没有可以在其上创建示例的计算机)，但我认为一个棘手的问题可能是您必须进入并明确设置网格行和/或列的高度、宽度或权重归零以回收空间.不过还是可以的.

It's been a while since I've done this (and don't currently have a computer on which to create an example), but I think the one sticky point may be that you will have to go in and explicitly set the grid row and/or column heights, widths or weights back to zero to reclaim the space. It's quite doable though.

您的另一个选择是通过方法或函数创建所有小部件.然后，您可以非常轻松地销毁和重新创建所有小部件.这对用户来说可能不太愉快，因为整个 UI 都会闪烁".

Your other choice is to create all of your widgets via a method or function. You can then pretty easily destroy and recreate all the widgets. This is probably less pleasant for the user since the whole UI will "blink".
