我想突出显示在PySide的QTextEdit中显示的文本中的单词,并且我发现PyQt的this answer相当不错并且工作良好,但它不适用于来自PySide的QTextEdit。在PySide.QTextEdit中突出显示文本
有人知道PySide在这里有什么问题吗?
这是我上面提到的答案代码:
from PyQt4 import QtGui
from PyQt4 import QtCore
class MyHighlighter(QtGui.QTextEdit):
def __init__(self, parent=None):
super(MyHighlighter, self).__init__(parent)
# Setup the text editor
text = """In this text I want to highlight this word and only this word.\n""" +\
"""Any other word shouldn't be highlighted"""
self.setText(text)
cursor = self.textCursor()
# Setup the desired format for matches
format = QtGui.QTextCharFormat()
format.setBackground(QtGui.QBrush(QtGui.QColor("red")))
# Setup the regex engine
pattern = "word"
regex = QtCore.QRegExp(pattern)
# Process the displayed document
pos = 0
index = regex.indexIn(self.toPlainText(), pos)
while (index != -1):
# Select the matched text and apply the desired format
cursor.setPosition(index)
cursor.movePosition(QtGui.QTextCursor.EndOfWord, 1)
cursor.mergeCharFormat(format)
# Move to the next match
pos = index + regex.matchedLength()
index = regex.indexIn(self.toPlainText(), pos)
if __name__ == "__main__":
import sys
a = QtGui.QApplication(sys.argv)
t = MyHighlighter()
t.show()
sys.exit(a.exec_())
它完全可与PyQt的,但是当我改变进口PySide它停止高亮的话。
PySide与PyQt的应该是怎么样的API的工作原理几乎相同。很多情况下,在很多情况下,您可以更改'import'行,而不是其他任何东西。那么,它究竟是如何“不工作”?你能显示一些代码吗? – 2013-10-07 23:04:16
我知道他们是非常相似的,但在这一个我认为是完全不同的东西。我添加了代码,谢谢 – Haiku
