wxpython textctrl style 动态文字颜色

问题描述

我正在尝试用wxpython（textCtrl）做一个高亮编辑器，问题是当我改变每个单词的颜色时它很慢，有时它不带颜色

import wx
from threading import Thread
import time


class MainFrame(wx.Frame):

    def __init__(self):
        wx.Frame.__init__(
            self,None,title='Variable TextCtrl style text color')
        self.panel = wx.Panel(self)
        self.tc0 = wx.TextCtrl(
            self.panel,-1,pos=(10,10),size=(350,100),style=wx.TE_RICH | wx.TE_MULTILINE)
        self.tc0.Bind(wx.EVT_TEXT,self.ChangeText)
        self.tc0.SetFont(wx.Font(28,wx.MODERN,wx.norMAL,False,u'Consolas'))
        self.SetDoubleBuffered(True)
        self.styleThread = StyleThread(self.tc0)

        self.Show()

    def ChangeText(self,event):
        self.styleThread.setApplyStyle(True)


class StyleThread(Thread):

    def __init__(self,txtCtrl):
        Thread.__init__(self)
        self.applyStyle = False
        self.setDaemon(True)
        self.start()
        self.tc0 = txtCtrl
        self.lastStyled = 0

    def run(self):
        while True:
            if self.applyStyle:
                self.style()
            #Even if I change the time the program start to require more resources
            time.sleep(0.5)

    def style(self):
        try:
            endLine = self.tc0.GetInsertionPoint()

            startLine = 0 if endLine < self.lastStyled else self.lastStyled

            word = ""

            unitary = False

            while startLine < endLine:
                character = self.tc0.GetValue()[startLine]


                if not character.isdigit() and character != "." and not character in ["+","-"]:
                    word += character

                if character in ["+","-"]:
                    self.tc0.SetStyle(self.tc0.GetInsertionPoint(
                    )-1,self.tc0.GetInsertionPoint(),wx.TextAttr(wx.RED))
                    word = ""
                elif word.strip() in ["Derivar","Integrar"] or word.strip() in ["Pi","Grados"]:
                    self.tc0.SetStyle(self.tc0.GetInsertionPoint(
                    )-len(word),wx.TextAttr(wx.GREEN))
                else:
                    self.tc0.SetStyle(self.tc0.GetInsertionPoint(
                    ),self.tc0.GetInsertionPoint()+1,wx.TextAttr(wx.BLACK))
                    unitary = True

                if unitary:
                    self.tc0.SetStyle(self.tc0.GetInsertionPoint(
                    )-len(word),wx.TextAttr(wx.BLACK))
                    unitary = False

                self.tc0.SetDefaultStyle(wx.TextAttr(wx.BLACK))
                startLine += 1
            self.lastStyled = endLine
        except:
            print("ERROR")

    def setApplyStyle(self,applyStyle):
        self.applyStyle = applyStyle


if __name__ == '__main__':
    app = wx.App()
    frame = MainFrame()
    app.MainLoop()

我读了很多，但我找不到为此目的的特殊事件，即使我使用了 StyledTextCtrl 并且我工作得很好，不幸的是屏幕阅读器不能完全访问它，因为它是应用程序。我想知道是否有任何方法可以做到这一点？谢谢:D
