[vlc] My first plugin

[YuGiOhJCJ Mailing-List]

Hello,

I am trying to develop a plugin for VLC which add the text to speech feature to heard the name of the current track.
So I am learning how to develop a plugin for VLC.
I read documentation to understand[1][2][3][4][5].
Also, I read the source code in the module/ directory to see examples.
Then, I read a HACKING file at the source code root. 
Finally, I have my first plugin [6].
I just want to display a window with a customised text to begin...
So I found the 'dialog_Question' function defined in vlc_dialog.h.
My plugin is listed in the Tools > Plugins and extensions > Plugins so this is good for me :-)
The problem is that the window is not visible.
Probably because the plugin is listed but not loaded.
I can read[5] that the modules are loaded automatically by VLC using the higher-score for a capability.
So I just need to put a big score like 152.
But if I do this, my plugin will be the only loaded in VLC for the "interface" capability and the other plugin with a score of 151 will not be loaded. But this plugin is also important.
So I would like to display a window with my plugin but it doesn't work.
Can you explain me how to do this?

Thank you.
