自定义IP控件添加到MINIGUI源码中

刚开始接触minigui，需要用到很多的自定义控件，原有的控件有限，所以需要将自定义控件添加到源码中。

使用MINIGUI1.6.10  自定义控件IP

 

添加方法：

1、首先编写IP控件(最后附加程序)

2、修改configure

 

    $ vim configure

 

    仿照edit 在963行添加 enable_ctrlipedit

 

               在1707行添加   --enable-ctrlipedit      include IPEDIT control <default=yes>

 

               在9778行添加 build_ctrl_ipedit="yes"

 

               在10223行添加     # Check whether --enable-ctrlipedit was given.
                                      if test "${enable_ctrlipedit+set}" = set; then :
                                      enableval=$enable_ctrlipedit; build_ctrl_ipedit=$enableval
                                      fi

               在12252行添加    if test "x$build_ctrl_ipedit" = "xyes"; then
                                     
                                     $as_echo "#define _CTRL_IPEDIT 1" >>confdefs.h
                                     
                                     fi
3、 修改configure.in

 

     $ vim configure.in

 

     在249行添加  build_ctrl_ipedit="yes"

 

     在560行添加  AC_ARG_ENABLE(ctrlipedit,
                      [  --enable-ctrlipedit      include IPEDIT control <default=yes>],
                      build_ctrl_ipedit=$enableval)

 

    在2003行添加  if test "x$build_ctrl_ipedit" = "xyes"; then
                       AC_DEFINE(_CTRL_IPEDIT, 1,
                       [Define if include IPEDIT control])
                       fi

 

4、 $ vim mgconfig.h

 

     添加 #define _CTRL_IPEDIT 1

 

5、 $ vim src/gui/ctrlclass.c

 

    添加  #ifdef _CTRL_IPEDIT
           extern BOOL RegisterIpEditControl(void);
           #endif

 

    添加 #ifdef _CTRL_IPEDIT
           if (!RegisterIpEditControl())
              return FALSE;
           #endif

 

6、 $ vim include/ctrl/Makefile.am

 

    在libminiguiinclude_HEADERS= 下添加ipedit.h

 

7、  $ vim include/ctrl/Makefile.in

 

      仿照edit.h的添加方式添加ipedit.h

 

8、 $ vim src/include/control/Makefile.am

  

      添加ipedit_impl.h

 

9、 $ vim src/include/control/Makefile.in

 

     noinst_HEADERS = 下添加ipedit_impl.h

 

10 、$ vim src/control/Makefile.am

 

     添加SRC_FILES = ctrlmisc.c ipedit.c/

 

11、$ vim src/control/Makefile.in

     SRC_FILES = ctrlmisc.c ipedit.c/

12 $ vim src/include/control.h  

 

     #ifdef _CTRL_IPEDIT
     #include "ctrl/ipedit.h"
     #endif

 

 

make

make install
