wxPython | wx.Toolbar 中的 CreateTool()函数

在这篇特别的文章中，我们将学习 wxPython 中 wx.ToolBar 类中的 CreateTool()函数。 CreateTool()函数是用于创建新工具栏工具的工厂函数。 CreateTool()函数仅创建使用 AddTool()函数进一步添加的工具。

Syntax:
wx.ToolBar.CreateTool(self, id, label, bitmap, bmpDisabled=wx.NullBitmap, kind=wx.ITEM_NORMAL, clientData=None, shortHelp=””, longHelp=””)

Parameters :

Parameter	Input Type	Description
toolid	int	An integer by which the tool may be identified in subsequent operations.
label	string	The string to be displayed with the tool.
bmpNormal	wx.bitmap	The primary tool bitmap.
bmpDisabled	wx.bitmap	The bitmap used when the tool is disabled.
kind	int	kind of toolbar.
clientData	PyUserData	An optional pointer to client data which can be retrieved later using GetToolClientData.
shortHelp	string	This string is used for the tools tooltip.
longHelp	string	detailed string associated with tool.

例子：

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()
        # create a tool using CreateTool() function
        self.ptool = self.toolbar.CreateTool(12,
                                             'oneTool',
                                             wx.Bitmap('path / wxPython / right.png'),
                                             shortHelp ="Simple Tool")
          
        self.btn = wx.Button(pnl, label ='Add created tool', 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):
        # Add toolbar tool using AddTool() function
        self.toolbar.AddTool(self.ptool)
        self.btn.SetLabel("Added tool")
  
def main():
  
    app = wx.App()
    ex = Example(None)
    ex.Show()
    app.MainLoop()
  
  
if __name__ == '__main__':
    main()
