我想为文字,背景和前景色都设置颜色。我首先学习了tkinter,但似乎wxpython没有类似的方法。
以下代码易于测试,复制" hello world,Hello World,heLLo WORLD"到area_example,告诉我如何突出显示"你好",ignorecase
#!/usr/bin/env python
# coding=utf8
import wx
rows = 5
cols = 2
vgap = 20
hgap = 10
class Search(wx.Frame):
#not_resizable = wx.DEFAULT_FRAME_STYLE ^ (wx.RESIZE_BORDER | wx.MAXIMIZE_BOX) # ok
not_resizable = wx.DEFAULT_FRAME_STYLE & ~(wx.RESIZE_BORDER | wx.MAXIMIZE_BOX)
def __init__(self, parent, title, size):
super(Search, self).__init__(parent, title=title, size=size, style=self.not_resizable)
self.init_elements()
self.lay_out()
self.Centre()
self.Show()
def init_elements(self):
self.panel = wx.Panel(self)
self.entry_name = wx.TextCtrl(self.panel)
self.entry_name.SetFocus()
self.btn_add = wx.Button(self.panel, label="Add")
self.btn_add.Disable()
self.btn_recite = wx.Button(self.panel, label="Recite")
self.btn_recite.Disable()
self.btn_flash = wx.Button(self.panel, label="Flash")
self.btn_flash.Disable()
self.label_phonetic = wx.StaticText(self.panel, label='')
self.area_meaning = wx.TextCtrl(self.panel, style=wx.TE_MULTILINE)
self.area_example = wx.TextCtrl(self.panel, style=wx.TE_MULTILINE)
self.btn_save = wx.Button(self.panel, label="Save")
self.btn_sort = wx.Button(self.panel, label="Sort")
def lay_out(self):
hbox = wx.BoxSizer(wx.HORIZONTAL)
grid = wx.FlexGridSizer(rows, cols, vgap, hgap)
grid.AddMany([
(self.entry_name), (self.btn_add),
(self.label_phonetic), (self.btn_recite),
(self.area_meaning, 1, wx.EXPAND), (self.btn_flash),
(self.area_example, 1, wx.EXPAND), (self.btn_sort),
(self.btn_save),
])
grid.AddGrowableCol(0, 1)
grid.AddGrowableRow(2, 1)
grid.AddGrowableRow(3, 1)
hbox.Add(grid, proportion=1, flag=wx.ALL | wx.EXPAND, border=15)
self.panel.SetSizer(hbox)
#self.panel.SetSizerAndFit(hbox)
def OnKeyUp(self, e):
code = e.GetKeyCode()
if code == wx.WXK_RETURN:
self.enter_handler(e)
def enter_handler(self, e):
word = self.entry_name.GetValue()
if word:
self.highlight(word)
def highlight(self, name):
# todo
# add background color and foreground color, ignore case
print 'highlight'
def search_test():
app = wx.App()
title = 'Search Test'
size = (800, 500)
s = Search(None, title, size)
s.entry_name.Bind(wx.EVT_KEY_UP, s.OnKeyUp)
app.MainLoop()
if __name__ == '__main__':
search_test()
当我问这个问题时的doc版本是wxPython 3.0.3,最后更新于2015年3月13日,修订版1725 + 2c3b7a8。
但osx上的wxPython版本brew安装版本为3.0.2,某些类和方法不可用。

在文档中,它解释了如何执行此操作:http://wxpython.org/Phoenix/docs/html/TextCtrl.html#phoenix-title-textctrl-styles
以下是一个示例代码段(应该低于您对self.area_example的定义)
self.area_example.SetDefaultStyle(wx.TextAttr(wx.RED))
self.area_example.AppendText("Red text\n")
self.area_example.SetDefaultStyle(wx.TextAttr(wx.NullColour,
wx.LIGHT_GREY))
self.area_example.AppendText("Red on grey text\n")
self.area_example.SetDefaultStyle(wx.TextAttr(wx.BLUE))
self.area_example.AppendText("Blue on grey text\n")
至于检查单词是否为“hello”,我现在只能想到绑定它并检查它。
self.area_example.Bind(wx.EVT_CHAR, self.OnKeyDown)
“OnKeyDown”功能只是一个例子。它运行但你很可能想要一个更好的方法。
def OnKeyDown(self, e):
last_word = self.area_example.GetValue().split()[-1]
if last_word.lower() == "hello":
print("Change color")
e.Skip()
从那里你应该能够完成你所需要的。
