wxWidgets uses native controls (on linux it will use GTK, motif or even xlib) on windows it uses the win32 api, etc,...
QT draws it's own controls, and thus doesn't look integrated into the OS.

. It should probably work fine with bcb.http://sourceforge.n...rojects/wxscintilla/
There is a wonderfull cross platform example of wxWidgets + scintella in the open source Code::Blocks IDE. (http://www.codeblocks.org/
