 Programming with Qt
Course Duration : Four Days: 9 am - 6 pm Course Fee : Rs. 15,000/- (plus service tax)
Course Overview
Qt is a multiplatform C++ application development framework. It has become the emerging standard development environment for IT professionals who want to write a single source-tree, port it to multiple platforms with a simple recompile, integrate it easily with Motif and ActiveX, make it database-capable, globalize it, give it a native look and feel, and run it at native speed. After completion you will have: A knowledge of the capabilities & limitations of Qt; A knowledge of multi platform development using Qt; Experience programming with Qt.
Pre-Requisites
Very good knowledge of the C++ programming language. Awareness of atleast on UI toolkit is a plus, but not required, Should be comfortable using a GNU/Linux distribution. Knowledge of OpenGL would be a plus (only for learning the Qt/OpenGL module)
Target Audience
Programmers developing applications for desktops, embedded devices and/or targeting multiple platforms - Windows, Unix and Mac will greatly benefit from this training.
