子控件自适应窗口大小的改变 对所有需要改变窗口大小的Dialog提供调用接口    * @方法功能:  子控件自适应窗口大小的改变        * @参数介绍：        -hWnd：要缩放的Dialog的窗口句柄，可在Dialog中通过GetSafeHwnd()方法获得;        -typeFlag: 缩放标志,其可能取值如下：0表示原始大小(缺省)，1最大化，2按照times的值放大或缩小一定倍数后居中。        -times : Dialog的放大倍数，缺省值为1.0，只有当typeFlag值为2时才有效    * @返回值：FALSE表示传入的第一个参数hWnd=NULL,否则返回TRUE；    * @注意事项：        -1、所有子控件的大小是按照原来的Dialog同比例进行放大，以免放大后失真        -2、放大后如果窗口大小超过显示器可用区域（除去任务栏），会自动调整使得窗口最大化但是长和宽的比例扔保持不变，以免失真        -3、放大后所有的子控件的字体采用的是系统默认字体，所有字体大小是放大后的统一大小        -4、当typeFlag=2&×

应用背景Build Instructions: Make sure you have autoconf, swig, texinfo, python-dev, build-essential packages or equivalent installed via your package manager. cd libredwg ./autogen.sh && ./configure && make && sudo make install cd ../dxflib ./configure && make && sudo make install cd .. Once the above dependencies have been built, edit /usr/local/include/dwg.h, and rename the THICKNESS constant (or add _ to end). It conflicts with another constant included in the converter, but is not used itself. After that, just run "make". That"s it! 关键技术GNU LibreDWG 是一个免费开源的 C 库用来处理 DWG 文件，这
