Qt's painting system is able to render vector graphics, images, and outline

font-based text with sub-pixel accuracy accuracy using anti-aliasing to

improve rendering quality.

These examples show the most common techniques that are used when painting

with Qt, from basic concepts such as drawing simple primitives to the use of

transformations.

The example launcher provided with Qt can be used to explore each of the

examples in this directory.

Documentation for these examples can be found via the Tutorial and Examples

link in the main Qt documentation.

Finding the Qt Examples and Demos launcher

==========================================

On Windows:

The launcher can be accessed via the Windows Start menu. Select the menu

entry entitled "Qt Examples and Demos" entry in the submenu containing

the Qt tools.

On Mac OS X:

For the binary distribution, the qtdemo executable is installed in the

/Developer/Applications/Qt directory. For the source distribution, it is

installed alongside the other Qt tools on the path specified when Qt is

configured.

On Unix/Linux:

The qtdemo executable is installed alongside the other Qt tools on the path

specified when Qt is configured.

On all platforms:

The source code for the launcher can be found in the demos/qtdemo directory

in the Qt package. This example is built at the same time as the Qt libraries,

tools, examples, and demonstrations.
