wxPython wx.ToolBar中的DeleteToolByPos()函数

在这篇文章中，我们将学习wxPython的wx.ToolBar类的DeleteToolByPos()函数。DeleteToolByPos()将指定的工具从工具栏中移除，并将其删除。DeleteTool()和DeleteToolByPos()函数之间的唯一区别是DeleteToolByPos()通过其索引指定工具。

语法： wx.toolbar.DeleteToolByPos(self, pos)

返回： 如果工具被删除，则为真，否则为假。

import wx
 
 
class Example(wx.Frame):
    global count
    count = 0;
    def __init__(self, *args, **kwargs):
        super(Example, self).__init__(*args, **kwargs)
 
        self.InitUI()
 
    def InitUI(self):
        pnl = wx.Panel(self)
        self.toolbar = self.CreateToolBar()
        self.ptool = self.toolbar.AddTool(12,
                                          'oneTool',
                                          wx.Bitmap('path / wxPython / right.png'),
                                          shortHelp ="Simple Tool")
         
        self.ptool = self.toolbar.AddTool(13,
                                          'oneTool',
                                          wx.Bitmap('path / wxPython / wrong.png'),
                                          shortHelp ="Simple Tool")
         
        self.btn = wx.Button(pnl,
                             label ='Delete',
                             pos =(20, 20))
 
        self.btn.Bind(wx.EVT_BUTTON, self.Onclick)
        self.toolbar.Realize()
        self.SetSize((350, 250))
        self.SetTitle('Control')
        self.Centre()
 
    def Onclick(self, e):
        # delete tool using DeleteTool() function
        self.toolbar.DeleteToolByPos(0)
 
 
def main():
 
    app = wx.App()
    ex = Example(None)
    ex.Show()
    app.MainLoop()
 
 
if __name__ == '__main__':
