Cross-Platform GUI Programming with wxWidgets (Paperback)
內容描述
Description
Unlike other cross-platform GUI
toolkits (Tcl/Tk, Qt, AWT) wxWidgets
supports the native look-and-feel of
the local OS. And unlike Qt, wxWidgets is
truly Open Source. It also works with
virtually every standard C++ compiler.
It is a perfect solution for
organizations interested in porting Windows
applications to Linux and other
platforms. And with Mac OS X and Linux
gaining marketshare daily, many
organizations -- including Xerox, Advanced
Micro Devices, AOL, Lockheed Martin,
NASA--have adopted wxWidgets in
order to support Windows, Linux, OS X,
and Unix for their applications. See
http://www.wxwidgets.org/
And wxWidgets is HOT. Mitch Kapor's
OSAF is using wxWidgets for its
Chandler PIM. Bram Cohen uses
wxWidgets for BitTorrent. Borland has
added enormous credibility to
wxWidgets by incorporating it into its newest
C++ IDE: C++ BuilderX. wxWidgets is
Borland's cross-platform
development
solution.
