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

时间:2022-05-15 07:13:18
'''
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)
