emwin自定义消息问题 -凯发k8官方网

例如我要定义一个wm_ic的消息

1.在emwin窗口文件的头文件.h文件中声明 #define wm_ic (wm_user 0x00)//自定义消息

2.然后在 switch (pmsg->msgid) {....}中定义一个case wm_ic：...break;

然后就是想在地方产生此消息用wm_sendmessagenopara(wm_getclientwindow(hdlg),wm_ic)即可

其中wm_getclientwindow为返回客户端窗口句柄。具体在《emwin5中文手册》窗口管理器（wm）中14.5wm api这一节中。
