QString::toStdString() crashes

今天在Qt中开发程序时,遇到一个QString::toStdString()的内存问题,用法如下:

void test(const QString& theFileName) { std::string aFileName = theFileName.toStdString(); std::ofstream aFile(aFileName); aFile << aFileName; }

在函数还没执行完就崩溃了,跟踪发现是std::string的问题。最后发现是因为引用的库的Runtime Library不同导致的,一个是MDd,一个是MTd,后来改成一致即可。

Consolas 字体

Consolas是一套等宽字体的?#20013;停?#23646;无衬线字体,由Lucas de Groot设计。
概述 这套?#20013;?#20351;用了微软的ClearType ?#20013;推交?#25216;术,并随同Windows Vista、Office 2007及Microsoft Visual Studio中发行,或可在微软的网站下载。在Windows Vista的6套新?#20013;?#20013;,Consolas近似于前版Windows中 的2款内建?#20013;停篖ucida Console与Courier New,主要为程序代码的显示?#20013;?#32780;设计的,特别之处是它的“0”字加入了一斜撇,以方便与字母“O”?#30452;妗? 在Consolas之前,程序代码的显示?#20013;?#22823;多为Courier New或其他等宽?#20013;停中?#30340;柔边(反锯齿)效果则依个人喜好选择开启或关闭,然而Consolas是专为柔边效果而设计的?#20013;停?#29305;别是为了搭配微软的ClearType技术,如果不开启ClearType,Consolas的显示效果会打大折扣。另外,ClearType技术还需要搭配液晶显示器才会有最佳表现。
应用 传统上,程式编写员在Windows环境底下,一般都会使用Courier New或其他近似的等宽字体来显示程序代码。通常用来编写程序代码的程序都会让编程员选择用来显示程序代码的字体。由于Courier New的?#20013;?#27604;较肥大,使每个画面或页面所能显示的程序代码大为减少。Consolas除了能够在较少的空间显示更多的内容,它的清晰?#20013;?#20134;使编程员能够更快捷的?#30452;?#27599;一个文字。

这个字体用来编码很清晰,舒服,主要是数字0和字母0可以容易的区别出来,这里做个备忘,方便在编码环境中设置这个字体。
