Is SciLexer.dll part of Boost Library? and Why adopted?

[Bin Wang]

Dear All,

i am very new to c++. but i very much appreciate the concept of Notepad++ development — use pure Win32 API to keep the performance.

my question are as below:
1 doe notepad++ use Boost Library?
2 the use of Boot library in notepad++ is for simplifying the GUI development ? if yes, can you give me some examples of GUI components referred in Boost by notepad++
3 what is SciLexer.dll for?

thanks in advance

1. Yes
2. No; Boost is used in Notepad++ for its regular expression engine, not any part of its GUI
3. SciLexer.dll is the (modified) Scintilla project code that is the core of Notepad++'s editing abilities
