About wxMediaCtrl in wxWidgets

Recently, I was running on wxMediaCtrl to make a MetroLyricMaker

to use wxMediaCtrl, you must pass  --enable-mediactrl to ../configure.


You may also install libgstreamermm-0.10-dev to build the library

wxWidgets in CodeBlocks

wxWidgets has upgraded to 2.9, and I'm migrated from Dev-Cpp to Code::Blocks

Following is the way to setup the wxWidgets project in Code::Blocks

You should build your library with MSYS

1. Open a project

2. Go through Project / Properties...

3. Go to Project's build options...

4. In Compiler settings / #defines tab, we will add some information here.

4.1 Open MSYS, type wx-config --cppflags, and the terminal will popup like:


-I/usr/local/lib/wx/include/msw-unicode-2.9 -I/usr/local/include/wx-2.9 -D_LARGEFILE_SOURCE=unknown -DWXUSINGDLL -D__WXMSW__


4.2 Copy the this part to #defines


5. Go through Linker settings


5.1 For the Link libraries part, you just copy the file's path that end with .dll.a to here by click Edit button.  After testing, without this step, it still works.


5.2 For the other linker options, type wx-config --libs in MSYS, and the terminal will popup like:



-L/usr/local/lib   -Wl,--subsystem,windows -mwindows -lwx_mswu_xrc-2.9 -lwx_mswu_html-2.9 -lwx_mswu_qa-2.9 -lwx_mswu_adv-2.9 -lwx_mswu_core-2.9 -lwx_baseu_xml-2.9 -lwx_baseu_net-2.9 -lwx_baseu-2.9

Copy the this part to Other linker options

6. Goto Search directories

6.1 In compiler tab, add the directory path

mines are:

C:\wx\wxWidgets-2.9.1\mswDebug\lib\wx\include\msw-unicode-2.9
C:\wx\wxWidgets-2.9.1\include


Note that there is always two paths there, former one for the library's setting (unicode? for example).  Later one is for other header files.


6.2 In Linker tab, add the directory path


mines is:


C:\wx\wxWidgets-2.9.1\mswDebug\lib


This is where the library place

如何在jade的環境下動態載入Agent並執行之

對於沒學過java，而直接寫jade的人，一定對這個標題有問題

有問題的原因就是：jade沒有提供function來做

可是在找過網路後，發現有 java.lang.ClassLoader 和 java.net.URLClassLoader 可以用。

使用方式如下：

try{
            URL url[] = new URL[1];
            url[0] = new URL("file:///pathTojar.jar");
            ClassLoader m_loader = new ClassLoader(url, ClassLoader.getSystemClassLoader());
            getContainerController().acceptNewAgent("test", (Agent)m_loader.loadClass("examples.hello.HelloWorldAgent").newInstance());
            getContainerController().getAgent("test").start();
        } catch(Exception e) {
            e.printStackTrace();
}

如此一來，就可以將jar檔裡的class檔讀出來，並動態執行之
