我在TKinter的样式中苦苦挣扎我的主要问题是您无法在树视图中单击任何内容。
要测试，只需按下“按测试”按钮
出于某种原因，style.theme_create接管了我的treeview小部件，无论我尝试什么，我似乎都无法找到解决方案。我尝试激活光标，selection_set，focus_set等。
如果我评论我可以单击的样式，但不能打开它。
我对python还是很陌生，将不胜感激。
我尝试了t1.bind（''）并试图找到一个选定的样式，但似乎无法使其工作，绑定本身不起作用。我已经阅读过文档，但是我尝试过的所有与选择有关的尝试似乎都失败了。

问题：无法在树视图中单击任何内容。
单击正常，您可以通过将回调绑定到事件'<Button...来进行验证。
def on_selected(event):
print('on_selected{}'.format(event))
t1.bind('<ButtonRelease-1>', on_selected)
参考：
widget.bind(event, handler)对于每个小部件，您可以将Python函数和方法绑定到事件。如果在窗口小部件中发生与事件描述匹配的事件，则将使用描述事件的对象来调用给定的处理程序。
您正在松开widget.bind(event, handler)样式，或者'selected'样式变为相同。因此，如果单击“行”，则会发生no颜色更改。
解决方案：在新的'!selected'中为'selected'小部件设置explicit一种Treeview样式。
theme参考：
style.theme_create("fclassic", parent="alt",
settings={
'Treeview': {
'map': {
'background': [('!selected', 'blue'), ('selected', 'red')],
'foreground': [('selected', 'black')],
'font': [('selected', ("Century Gothic", 10, 'bold'))],
} # end 'map'
} # end 'Treeview'
} # end settings
)
