gtk学习笔记01 helloworld

1. 先贴出油管大佬的教程博客https://prognotes.net/category/gtk-3/链接

2. 然后是https://www.cnblogs.com/tennysonsky/p/4257037.html链接

3. 接着是一些cairo的示例程序https://zetcode.com/gfx/cairo/链接

4. 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
     
     

5. 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
      

6. 解压后得到目录gtk+-3xxx

   • 我这里放到了H:mysoftclionclionWorkSpace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）
     

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

   1. H:mysoftclionclionWorkSpace部分需要自己修改哦
   2. 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/include/gdk-pixbuf-2.0
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/glib-2.0/include
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/gtk-3.0/include
      )
      
      

   3. 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
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libcairo-script-interpreter.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libcairo.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libcroco-0.6.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libffi.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libfontconfig.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libfreetype.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libgailutil-3.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libgdk-3.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libgdk_pixbuf-2.0.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libgio-2.0.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libglib-2.0.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libgmodule-2.0.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libgobject-2.0.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libgthread-2.0.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libgtk-3.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libjasper.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libjpeg.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/liblzma.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libpango-1.0.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libpangocairo-1.0.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libpangoft2-1.0.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libpangowin32-1.0.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libpixman-1.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libpng.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libpng15.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/librsvg-2.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libtiff.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libtiffxx.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libxml2.dll.a
              H:/mysoft/clion/clionWorkSpace/gtk+364/lib/libz.dll.a
      )
      

   4. 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)
      

8. 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;
       }
   

9. 点击clion的小绿锤子编译（当然是可选的）得到.exe可执行文件

   • 

10. 把可执行文件和那些.dll放到同级目录下，双击运行即可（我还不知道如何把他们打包成单个可执行文件）
