wxpython中的所有文本框都是TextCtrl，不同的形式的文本框通过样式来实现，下面创建了一个密码输入框
''' |
wx.TE_CENTER：控件中的文本居中。 |
wx.TE_LEFT：控件中的文本左对齐。默认行为。 |
wx.TE_NOHIDESEL：文本始终高亮显示，只适用于Windows。 |
wx.TE_PASSWORD：不显示所键入的文本，代替以星号显示。 |
180 / 565 |
wx.TE_PROCESS_ENTER：如果使用了这个样式，那么当用户在控件内按下回车 |
键时，一个文本输入事件被触发。否则，按键事件内在的由该文本控件或该对话框管 |
理。 |
wx.TE_PROCESS_TAB：如果指定了这个样式，那么通常的字符事件在Tab键按下 |
时创建（一般意味一个制表符将被插入文本）。否则，tab由对话框来管理，通常是 |
控件间的切换。 |
wx.TE_READONLY：文本控件为只读，用户不能修改其中的文本。 |
wx.TE_RIGHT：控件中的文本右对齐。 |
用法： |

pwdText = wx.TextCtrl(panel, -1, ”password”, size=(175,-1),style=wx.TE_PASSWORD | wx.TE_PROCESS_ENTER) |
