KDE Contributor and Developer Conference
2004 KDE Community World Summit
Speaker:David Faure
Language: English
Talk is scheduled for: Sunday, 22nd of August 2004, 16:30 - 17:30
Check the Schedule for an overview of all talks during this conference.
Qt is without doubt a wonderful toolkit that is very well designed. However, well designed it is, there will always be tiny details here or there that is utterly hard to implement, or perhaps just non obvious.
Kalle and Jesper have in their book "Practical Qt" (which should be in book stores just about aKademy) described 85 different problems in Qt plus solution for these.
The problems range from rather simple problems like:
- How to hide the header in a listview
- How to get titles in pop up menus
Over more exotic questions like
- How do I implement a double QSplitter that splits a window in four
- How do I emit a signal from a const method
To hard questions like
- How do I implement a widget that uses a combo box for editing items in QListview
- How do I set up communication among threads.
Basically the book consist of two kinds of problems:
- problems that lots of people faces
- problems that shows a general way of solving issues with Qt
In this presentation we will show examples from the book, among these
- An intelligent busy cursor
- Shoot a bug (An interesting debugging approach)
- How do I set up communication among threads
- Clipping to non-rectangular and non-contiguously regions
and if time permits
- Determining screen properties
- A QProgress dialog showing time to completion
- A QSpinBox with floating point numbers
