How to create plugin like "Look up" for selected text?

i need to  create plugin "look up" selected text. can guve hint starting plugin

0. if don't have c/c++ skills, wrong project doing first.

 

1.  if don't have sdk, download it. constant companion time come. read developer faq in entirety.

 

2. consider compatibility. should download sdk oldest version of acrobat want end users able use. (sdks older 9.0 not available).

 

3. if have never built plug-in, compile , test of samples, sure works.

 

4. if want build plug-in reader, can't. not without following many restrictions , getting license , key, described in sdk. need acrobat development.

 

5. purposes, basic knowledge of pdf file format must. (this case might exception).

 

6. plug-in free use apis on system run on, 2 key exceptions: (a) threading , (b) takes while because block acrobat. (threading not impossible, requires great care ensure acrobat not called thread.

 

for specific project...

i don't think can add context menu you'll need add tool button function. button can find out type of selection, verify text, text unicode, , process it.
