gtk学习笔记01 helloworld

本文主要是介绍gtk学习笔记01 helloworld，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

首先要有非常好用的clion工具
- clion选择编译器，我这里选择了MinGW
  file->settings->ToolChains->点击+号(我这里自动识别了）->OK
- 并且去配置cmake生成debug和release
  - debug是默认有的，release我点加号的时候也自动识别了
- 新建一个c++工程file -> new project -> c++ project并得到目录结构
搭建开发环境
1. 下载GTK+ 3.6.4 Bundle for Windows
  
  网址http://www.tarnyko.net/dl/gtk.htm
解压后得到目录gtk+-3xxx
- 我这里放到了H:\mysoft\clion\clionWorkSpace目录下
- 下面有bin，include和lib之类的目录
- bin目录下的dll是要放在编译好.exe文件的同级目录下，.exe文件才能运行（windows下优先搜索当前文件夹下的dll）

把include和lib里的东西添加到cmakelists.txt(使用cmake构建)

H:\mysoft\clion\clionWorkSpace部分需要自己修改哦

include的

include_directories(
        H:/mysoft/clion/clionWorkSpace/gtk+364/include
        H:/mysoft/clion/clionWorkSpace/gtk+364/include/gtk-3.0
        H:/mysoft/clion/clionWorkSpace/gtk+364/include/cairo
        H:/mysoft/clion/clionWorkSpace/gtk+364/include/gdk
        H:/mysoft/clion/clionWorkSpace/gtk+364/include/glib-2.0
        H:/mysoft/clion/clionWorkSpace/gtk+364/include/pango-1.0
        H:/mysoft/clion/clionWorkSpace/gtk+364/include/atk-1.0

        H:/mysoft/clion/clionWorkSpace/gtk+364/lib/glib-2.0/include
        H:/mysoft/clion/clionWorkSpace/gtk+364/lib/gtk-3.0/include
)

lib的所有.a文件

link_libraries(
        H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libatk-1.0.dll.a
        H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libcairo-gobject.dll.a

使用Mingw编译好.exe后，双击运行时会弹出黑窗口控制台，在cmakelists.txt里添加以下代码可消除黑窗口

# mingw消除黑窗口 C++工程
set(CMAKE_CXX_FLAGS ${CMAKE_CXX_FLAGS} -mwindows)

# mingw消除黑窗口 C 工程
# set(CMAKE_C_FLAGS ${CMAKE_C_FLAGS} -mwindows)

编写helloworld代码，把以下代码拷贝到main.cpp里面

    #include <gtk/gtk.h>
    #include <string.h>

    int main(int argc, char **argv) {
        GtkWidget *window;
        // 要先init
        gtk_init(&argc, &argv); 
        // 才能new
        window = gtk_window_new(GTK_WINDOW_TOPLEVEL);

        g_signal_connect(window, "delete_event", gtk_main_quit, NULL);
        gtk_widget_show_all(window);
        gtk_main();
        return 0;
    }
