TKinter样式和Treeview点击问题 [英] TKinter Style & Treeview Click Issues
问题描述
我正在为TKinter的样式苦苦挣扎 我的主要问题是您无法在树形视图中单击任何内容.
I am struggling with styles in TKinter My main problem is that you cannot click anything in the treeview.
要进行测试，只需按下按测试"按钮
To test, simply press the "Press To Test" Button
由于某种原因，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.
For some reason it looks like, style.theme_create takes over my treeview widget, and no matter what I try, I cannot seem to find a solution around it. I tried activating the cursor, selection_set, focus_set, etc.
如果我评论了我可以单击的样式，但没有打开它.
If I comment the style I can click, but not with it on.
我对python还是很陌生，希望能获得一些见识.
I am still quite new to python and would appreciate some insight.
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.我已经阅读了文档，但是我尝试过的所有与选择有关的尝试似乎都失败了.
I tried the t1.bind('') and tried to find a selected style but can't seem to make it work, the bind on its own doesn't work. I've read the documentation but all i've tried related to the selection seems to fail.

推荐答案
问题:无法在树形视图中单击任何内容.
使用.theme_create会禁用Treeview中的selected样式.
Question: cannot click anything in the treeview.
Using.theme_createdisablesselectedstyle inTreeview.
点击正常，您可以通过将回调绑定到事件'<Button...来验证这一点.
Click is working, you can verify this by binding a callback to the event '<Button....
def on_selected(event):
print('on_selected{}'.format(event))
t1.bind('<ButtonRelease-1>', on_selected)
参考:
对于每个小部件，您都可以将Python函数和方法绑定到事件. 如果在窗口小部件中发生了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.
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.
您正在松开'selected'样式，或者'!selected'样式变得相同.因此，如果单击行"，则不会发生颜色变化.
You are loosing the 'selected' style or the '!selected' style becomes the same. Therefore no color change happens if you click at a Row.
解决方案:
在新的theme中为Treeview小部件设置显式一种'selected'样式.
Solution:
Set explicit a 'selected' style for the Treeview widget in your new theme.
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
)
