TKinter 样式和 Treeview 点击问题
TKinter Style & Treeview Click Issues
我正在为 TKinter 中的样式而苦苦挣扎
我的主要问题是您无法单击树视图中的任何内容。
要进行测试，只需按 "Press To Test" 按钮
出于某种原因，style.theme_create 似乎接管了我的树视图小部件，无论我如何尝试，似乎都找不到解决方案。我尝试激活光标，selection_set、focus_set 等
如果我评论我可以点击的样式，但不能打开它。
我对 python 还是很陌生，希望能提供一些见解。
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。我已阅读文档，但我尝试的与选择相关的所有操作似乎都失败了。

Question: cannot click anything in the treeview.
Using .theme_create disables selected style in Treeview.
点击有效，您可以通过将回调绑定到事件来验证这一点 '<Button...。
def on_selected(event):
print('on_selected{}'.format(event))
t1.bind('<ButtonRelease-1>', on_selected)
参考：
widget.bind(event, handler)
For each widget, you can bind Python functions and methods to events.
If an event matching the event description occurs in the widget, the given handler is called with an object describing the event.
您正在失去 'selected' 风格或 '!selected' 风格变得相同。因此 no 如果您单击某行，颜色会发生变化。
解决方法:
为新 theme 中的 Treeview 小部件设置 explicit 'selected' 样式。
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
)
