Map Projection Basics in Qt--help needed

[swamyonline]

hi ppl,
im new to qt. in my application i want to use a geographical map of a city in 2D. the requirement is: i should be able to add points, lines, place marks onto it,, draw x,y values in real time, zooming operations. can some body put some light onto this issue. how can i do it..

the main idea is to use a map in a simple qt application and plot points on it with zoom operations... thanks in advance for ur suggestions...bye

Long story short - switch to Qt4 and use Graphics View. Sticking to Qt3 might get you nowhere - the canvas module (which is a Qt3 counterpart to GraphicsView) is too crude and buggy to handle the things you want.
