推荐答案

您可以使用 QTextCharFormat 来设置 QPlainTextEdit 中文本的颜色.使用 QTextCharFormat::setForeground设置颜色.然后使用样式表通过 color 属性更改光标的颜色.

You can use QTextCharFormat to set the color of the text in your QPlainTextEdit. Use the QTextCharFormat::setForeground to set the color. Then use a stylesheet to change the color of the cursor by using the color property.

QPlainTextEdit *p_textEdit = new QPlainTextEdit;
p_textEdit->setStyleSheet("QPlainTextEdit{color: #ffff00; background-color: #303030;"
                          " selection-background-color: #606060; selection-color: #ffffff;}");
QTextCharFormat fmt;
fmt.setForeground(QBrush(QColor(255,255,255)));
p_textEdit->mergeCurrentCharFormat(fmt);
