vincentwei / mgncs4touch Goto Github PK

你好， 我运行了下hscrollview(samples/hscrollview.c)，但是发现鼠标如果按住移出窗口后，scroll view不能自动回滚。看了下代码貌似鼠标移出事件被底层处理后，没有发给scroll view。
请问下如何解决？

编译mgncs4touch时总是报下面libmgplus.so相关的信息，在编译mgplus时，已经加入了--enable-ft2support=yes

执行编译sudo ./configure; sudo make; sudo make install 编译mgncs4时，遇到报错。当前未找到原因
