在windows下使用Qt5開發GTK3圖形界面應用程序

首先，去MSYS2官網下載MSYS2環境並安裝在C:/mysys64下，我安裝的是64位的。進入MSYS命令行執行：

pacman -S mingw-w64-x86_64-gtk3

pacman -S mingw-w64-x86_64-toolchain base-devel

在工程的*.pro文件內加入頭文件和庫文件：

INCLUDEPATH += C:/msys64/mingw64/include/gtk-3.0 C:/msys64/mingw64/include/cairo C:/msys64/mingw64/include C:/msys64/mingw64/include/pango-1.0 C:/msys64/mingw64/include/atk-1.0 C:/msys64/mingw64/include/cairo C:/msys64/mingw64/include/pixman-1 C:/msys64/mingw64/include C:/msys64/mingw64/include/freetype2 C:/msys64/mingw64/include/libpng16 C:/msys64/mingw64/include/harfbuzz C:/msys64/mingw64/include/glib-2.0 C:/msys64/mingw64/lib/glib-2.0/include C:/msys64/mingw64/include C:/msys64/mingw64/include/freetype2 C:/msys64/mingw64/include C:/msys64/mingw64/include/harfbuzz C:/msys64/mingw64/include/libpng16 C:/msys64/mingw64/include/gdk-pixbuf-2.0 C:/msys64/mingw64/include/libpng16 C:/msys64/mingw64/include/glib-2.0 C:/msys64/mingw64/lib/glib-2.0/include C:/msys64/mingw64/include

LIBS += -LC:/msys64/mingw64/lib -lgtk-3 -lgdk-3 -lgdi32 -limm32 -lshell32 -lole32 -Wl,-luuid -lwinmm -ldwmapi -lsetupapi -lcfgmgr32 -lz -lpangowin32-1.0 -lpangocairo-1.0 -lpango-1.0 -latk-1.0 -lcairo-gobject -lcairo -lgdk_pixbuf-2.0 -lgio-2.0 -lgobject-2.0 -lglib-2.0 -lintl

*如果出現make找不到的情況，在構建設置裏手動設置一下就行了。

#include

int main(int argc, char *argv[])
{
GtkWidget *window;
GtkWidget *label;
//初始化GTK+庫
gtk_init(&argc, &argv);
//創建主窗口
window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
//設置窗口大小
gtk_widget_set_size_request(window,300,300);
//設置標題
gtk_window_set_title(GTK_WINDOW (window), "Hello World");
//當窗口即將被銷毀，停止主GTK+循環
g_signal_connect(window, "destroy",G_CALLBACK (gtk_main_quit), NULL);
//創建一個"Hello World"標籤
label = gtk_label_new("Hello, World");
//將標籤加入到主窗口
gtk_container_add(GTK_CONTAINER (window), label);
//設置窗口中的所有元素可見
gtk_widget_show_all(window);
//開始主循環，讓它在那裡休息，直到應用程序關閉
gtk_main;
return 0;
}
