我一直在寻找一种方法,将输入textctrl字段的文本转换为大写。我尝试使用验证器并使用'ord'将键事件对象的值转换为大写字母char值但是我找不到任何'set'方法。我可能能够直接访问事件类变量,因为python中的类变量从来都不是私有的,但我很难找到我需要的确切信息。
无论如何,这似乎是一种过于复杂的方法。有没有人有任何建议。我错过了一些明显的东西吗?

试试这个。
import wx
class UpperTextCtrl(wx.TextCtrl):
def __init__(self, *args, **kwargs):
super(UpperTextCtrl, self).__init__(*args, **kwargs)
self.Bind(wx.EVT_TEXT, self.on_text)
def on_text(self, event):
event.Skip()
selection = self.GetSelection()
value = self.GetValue().upper()
self.ChangeValue(value)
self.SetSelection(*selection)
class Frame(wx.Frame):
def __init__(self):
super(Frame, self).__init__(None, -1, 'Uppercase Text Control')
panel = wx.Panel(self, -1)
sizer = wx.BoxSizer(wx.VERTICAL)
text = UpperTextCtrl(panel, -1, style=wx.TE_MULTILINE)
# change the font
font = text.GetFont()
font.SetPointSize(12)
text.SetFont(font)
sizer.Add(text, 1, wx.EXPAND|wx.ALL, 10)
panel.SetSizer(sizer)
if __name__ == '__main__':
app = wx.PySimpleApp()
frame = Frame()
frame.Show()
app.MainLoop()

检查此解决方案。
import wx
import string
class UpperTextCtrl(wx.TextCtrl):
def __init__(self, *args, **kwargs):
super(UpperTextCtrl, self).__init__(*args, **kwargs)
self.Bind(wx.EVT_CHAR, self.on_char)
def on_char(self, event):
key=event.GetKeyCode()
text_ctrl=event.GetEventObject()
if chr(key) in string.letters:
text_ctrl.AppendText(chr(key).upper())
return
event.Skip()
class Frame(wx.Frame):
def __init__(self):
super(Frame, self).__init__(None, -1, 'Uppercase Text Control')
panel = wx.Panel(self, -1)
sizer = wx.BoxSizer(wx.VERTICAL)
text = UpperTextCtrl(panel, -1, style=wx.TE_MULTILINE)
# change the font
font = text.GetFont()
font.SetPointSize(12)
text.SetFont(font)
sizer.Add(text, 1, wx.EXPAND|wx.ALL, 10)
