一、设置颜色,支持html语言格式的
ui->textEdit->append("<font color=\"#FF0000\">红色字体</font> ");
信息显示用到,错误的红色字体
光标移到后面
teMsg_->moveCursor(QTextCursor::End);
void MainWidget::slotShowMsg(MainWidget::MsgType type,QString msg) { if(type==MSG_ERROR) { msg="<font color=\"#ff0000\">"+msg+"</font>"; } teMsg_->append(QDateTime::currentDateTime ().toString ("[yyyy/MM/dd hh:mm:ss zzz] ")+msg); logCount_++; if(logCount_>LOG_MAX_SIZE) { teMsg_->clear(); logCount_=0; //qDebug()<<"clear"; } teMsg_->moveCursor(QTextCursor::End); }
