[英]what does -1 indicate in wx.ListCtrl in wxpython
can anyone help me out knowing what does -1 indicate in following line of code?谁能帮助我知道 -1 在以下代码行中表示什么?
self.lst2 = wx.ListCtrl(self.right_panel, -1, style=wx.LC_LIST)
Also, what does ('') indicate in following line of code?另外,('')在以下代码行中表示什么?
self.lst1.InsertItem(0, '')
@Bhagya, @Bhagya,
For the first question:对于第一个问题:
In that code snippet -1
is the ID of the control.在该代码段中,
-1
是控件的 ID。
You can assign your own ID but -1 means that you let wxPython assign the ID for you.您可以分配自己的 ID,但 -1 表示您让 wxPython 为您分配 ID。
For the second question:对于第二个问题:
It means that you are inserting empty string into the control.这意味着您正在将空字符串插入控件。
