Python 如何创建由tkinter中的for循环生成的图像按钮的单选按钮类型组
我现在很难让这段代码按照我需要的方式工作。本质上,我需要它像一个单选按钮一样工作,其中所选的“节点”(通过鼠标单击)将更改为不同的图像 节点由for循环生成,节点数量取决于一些外部输入。每个按钮都有悬停图像的绑定。我目前的两次尝试基本上是向for循环中的节点添加一个命令,该命令确定按下了哪个按钮(使用输入列表的索引),并使用grid将另一个图像放置在同一网格空间中的节点顶部。这一半可以工作,但似乎会暂时删除所有其他节点,直到激活悬停绑定。runNodes列表是一个旧解决方案的一部分,它的结果与此基本相同。为了能够引用节点,我暂时将它放在那里,但我甚至不确定我是否正确地这样做 或者,我尝试向我创建的自定义按钮类添加另一个绑定,在该绑定中,单击鼠标,图像将更改为所选图像。不幸的是,当鼠标离开节点时,鼠标悬停绑定会将其删除 我有一种感觉,这些解决方案中的一个或两个都可以工作,但我的代码中缺少了一些可以让它们工作的东西。。然而,我也愿意接受完全不同的解决方案。我已经包含了我认为相关的代码,但是如果需要更多信息,请告诉我。下面提供的代码代表我的两个解决方案中的前一个。后者只是创建了另一个类似于hoverOn和hoverOff的函数,使用mouseclick绑定。任何帮助都将不胜感激Python 如何创建由tkinter中的for循环生成的图像按钮的单选按钮类型组,python,tkinter,radio-button,Python,Tkinter,Radio Button,我现在很难让这段代码按照我需要的方式工作。本质上,我需要它像一个单选按钮一样工作,其中所选的“节点”(通过鼠标单击)将更改为不同的图像 节点由for循环生成,节点数量取决于一些外部输入。每个按钮都有悬停图像的绑定。我目前的两次尝试基本上是向for循环中的节点添加一个命令,该命令确定按下了哪个按钮(使用输入列表的索引),并使用grid将另一个图像放置在同一网格空间中的节点顶部。这一半可以工作,但似乎会暂时删除所有其他节点,直到激活悬停绑定。runNodes列表是一个旧解决方案的一部分,它的结果与此
