c/c++语言开发共享Qt开源编辑器qsciscintilla的一些用法

//设置字体
qfont font("courier", 10, qfont::normal);      ui->textedit->setfont(font);      ui->textedit->setmarginsfont(font);      qfontmetrics fontmetrics = qfontmetrics(font);
//设置左侧行号栏宽度等      ui->textedit->setmarginwidth(0, fontmetrics.width("00000"));      ui->textedit->setmarginlinenumbers(0, true);      ui->textedit->setbracematching(qsciscintilla::sloppybracematch);      ui->textedit->settabwidth(4);
//设置括号等自动补全      ui->textedit->setautoindent(true);
//初始设置c++解析器      ui->textedit->setlexer(new qscilexercpp(this));   //设置自动补全      ui->textedit->setcaretlinevisible(true);
//设置光标所在行背景色      ui->textedit->setcaretlinebackgroundcolor(qt::lightgray);       // ui->textedit->setcursorposition(2,2);      //int markerdefine(markersymbol sym, int markernumber = -1);      ui->textedit->sendscintilla(qsciscintilla::sci_setcodepage,qsciscintilla::sc_cp_utf8);//设置编码为utf-8
//得到光标位置
int line,col;
ui->textedit->getcursorposition(&line,&col);
