一直崇拜c/c++的牛人，崇拜那些只有几百K甚至几十K的程序。
我知道只有C/C++可以帮助我。 我的内心发出狂热的呼喊：我要学C++ 于是无奈之下安装了N个G的Visual studio。。。 Visual C++，我回来了，请不要抛弃我，虽然以前我没有耐心的学习你。。。 我潜心阅读MSDN的文档。。。 MFC，不是我想要的。。。一个很莫名奇妙的框架，以前就是他这个第三者破坏了我和C++良好的感情 Winform是什么？？原来是披着C++外衣的.net狼。 我要的是最美最纯的C，接受C++其实是一种妥协，但还要我接受这些浮华的勒涩吗？NO！！！ 我知道，windows下我也可以用printf来写最纯的C，但是，我们还需要GUI，除了要单纯的心，我们要一个美丽的脸庞。 GDI、GDIPlus，WIN API，非常好，我终于找到我的梦中情人了，我要的就是这样的最单纯的程序。 我潜心的读相关的文档，就像在读着盼望已久的情书。。。 TRUE，FALSE，VOID，怎么不是 true ，false ，void，我是不是看花了。 WCHAR NWPSTR, LPWSTR, PWSTR; 。。。 我理解这良苦用心，希望我更容易看懂。 INT_PTR，LRESULT 。。。 虽然我很爱她，但我终于忍不住对她发火了：美女，请问你真的是C小姐吗？你可以正常点说话吗？ Please help me ， How could I found my Miss C ？ =================================== 最后补充一下，看了下WCHAR，LPWSTR这些玩意的定义，最终是用到了 __wchar_t 这个非标准的关键字。 MS定义这些别名我想也是为了适应将来的编译器变化。 另外在32位和64位操作系统中，int、long、的长度也是不一样的，甚至64位windows和64位的 nix的long长度也不一样。 请看此文：一个长整数的自述 说到底 c/c++ 标准还不完善，但是我比较不满“Visual C++”的是，他太special了。 声明：ITeye文章版权属于作者，受法律保护。没有作者书面许可不得转载。

mikeandmore 写道 lz投奔linux吧。。。。
你在耍小白么？诸如wchar是C++标准中的unicode字符，你就是滚到linux里也是如此.GCC gui的能力弱得要死. 另外有一些是windows api的，你不调用Windows API，何必关注？ LZ到底是要从C写GUI界面，还是用C++写GUI界面？ 以我看来，你还是放弃想用C写界面的想法吧：一个什么都不做的Windows界面，用C大概要300多行,你自己要去处理所有的消息。。 用MFC创建个界面，那不是相当简单的么？何至于那么难哈？ 下面就是纯C写的，不知道楼主看了有什么感想

在win上要是不嫌界面不好看的话，可以试试gtk这玩意儿，我觉得这东东写些简单的程序用glade生成xml还是比较方便的。

ray_linn 写道 mikeandmore 写道 lz投奔linux吧。。。。
你在耍小白么？诸如wchar是C++标准中的unicode字符，你就是滚到linux里也是如此.GCC gui的能力弱得要死. 另外有一些是windows api的，你不调用Windows API，何必关注？ LZ到底是要从C写GUI界面，还是用C++写GUI界面？ 以我看来，你还是放弃想用C写界面的想法吧：一个什么都不做的Windows界面，用C大概要300多行,你自己要去处理所有的消息。。 用MFC创建个界面，那不是相当简单的么？何至于那么难哈？ 涨见识了啊。gcc和gui能联系到一起。。。。真是搞笑。。。 再说wchar_t也不只是C++标准，见C99标准7.24节 |

七猫 写道 在win上要是不嫌界面不好看的话，可以试试gtk<script type="text/javascript" src="http://www.iteye.com/javascripts/tinymce/themes/advanced/langs/zh.js"></script><script type="text/javascript" src="http://www.iteye.com/javascripts/tinymce/plugins/javaeye/langs/zh.js"></script>这玩意儿，我觉得这东东写些简单的程序用glade生成xml还是比较方便的。
非得在win下么，gtk这东西在linux下非常方便的，glade随便拖拖，生成一个gtkbuilder的xml，然后直接加载就好了。。。 |

于是给lz个sample。顺便来反驳一下C写UI是绝对恶心的观点。
#include <gtk/gtk.h>
static void
btn_clicked(GtkButton* wid, gpointer user_data)
{
GtkWidget* dlg = gtk_message_dialog_new(NULL, GTK_DIALOG_MODAL,
GTK_MESSAGE_INFO, GTK_BUTTONS_OK,
"Hello World!");
gtk_dialog_run(GTK_DIALOG(dlg));
gtk_widget_destroy(dlg);
}
int
main(int argc, char* argv[])
{
gtk_init(&argc, &argv);
GtkWidget* win = gtk_window_new(GTK_WINDOW_TOPLEVEL);
GtkWidget* btn = gtk_button_new_with_label("click me");
g_signal_connect(btn, "clicked", G_CALLBACK(btn_clicked), NULL);
gtk_container_add(GTK_CONTAINER(win), btn);
gtk_widget_show_all(win);
gtk_main();
return 0;
}
一共25行 |
