File ViewMessageTest.cpp, 3.4 KB (added by simonsouth, 23 months ago)

Indicates which messages are actually received by BView.

Line 
1// Tests whether certain messages are received by a BView instance.
2//
3// Compile and execute with:
4//
5// g++ -lbe -o ViewMessageTest ViewMessageTest.cpp
6// ./ViewMessageTest
7//
8// Please run this on a real BeOS instance and using the keyboard and mouse,
9// try to check as many boxes as possible. Then post a screenshot with the
10// results.
