单击空白后清除选择 space

Question

我目前正在使用 python 3.9 并尝试在单击空白后清除选择 space
它看起来像 this.

这是我的代码：

fileTreeView = ttk.Treeview(m, name='fileTreeView')
fileTreeView['columns']=('name', 'datem', 'type', 'size', 'blankspace')
fileTreeView.column('#0', width=0, stretch=NO)
fileTreeView.column('name',  width=60)
fileTreeView.column('datem',  width=60)
fileTreeView.column('type',  width=60)
fileTreeView.column('size',  width=60)
fileTreeView.column('blankspace', width=60)

fileTreeView.heading('#0')
fileTreeView.heading('name', text='Name')
fileTreeView.heading('datem', text='Date modified')
fileTreeView.heading('type', text='Type')
fileTreeView.heading('size', text='Size')
fileTreeView.heading('blankspace', text="")

我希望当单击空白space 列时，它会清除选择。

提前致谢！

你可以在<Button-1>事件的回调中找到被点击的列，如果是blankspace则清除选择：

def on_clicked(event):
    # get the column index being clicked
    col = fileTreeView.identify_column(event.x)
    # get the column name of the clicked column
    name = fileTreeView.column(col, 'id')
    if name == 'blankspace':
        # clear the selection
        fileTreeView.selection_set()
        # disable default mouse click handler
        return 'break'

fileTreeView.bind('<Button-1>', on_clicked)
