[英]ttk Treeview selection_set can't accept spaces
I'm building a gui using tkk in python and I'm having trouble with the Treeview
command selection_set()
.我正在使用 python 中的 tkk 构建一个 gui,我在使用
Treeview
命令selection_set()
遇到了问题。 I'm trying to use it to set the default selection when my program starts but it seems that it can't accept a string with spaces in it.我试图在我的程序启动时使用它来设置默认选择,但它似乎不能接受带有空格的字符串。
tree.selection_set("Sunset Grill")
Causes:原因:
return self.tk.call(self._w, "selection", selop, items)
_tkinter.TclError: Item Sunset not found
Can anyone give any suggestions?任何人都可以提供任何建议吗?
You might try the following:您可以尝试以下操作:
tree.selection_set('"Sunset Grill"')
I'm guessing this based on the code for ttk.py
and my limited understanding of Tcl.我猜测这是基于
ttk.py
的代码和我对 Tcl 的有限理解。 The call to tree.selection_set()
calls self.selection("set", items)
, which in turn calls self.tk.call(self._w, "selection", selop, items)
where selop
is 'set'
and items is the string initially passed to selection_set()
.对
tree.selection_set()
调用调用self.selection("set", items)
,后者又调用self.tk.call(self._w, "selection", selop, items)
其中selop
是'set'
和 items是最初传递给selection_set()
的字符串。
I'm not sure if the self.tk.call()
is doing any massaging of the arguments before passing them to Tcl as it's a call into the _tkinter.c module
and I don't know enough about the Python/C interface to grok that code.我不确定
self.tk.call()
在将参数传递给 Tcl 之前是否对参数进行了任何按摩,因为它是对_tkinter.c module
的调用,而且我对 Python/C 接口_tkinter.c module
理解那个代码。 ;)
尝试tree.selection_set(["Sunset Grill"])
