The Qt® 4 Resource Center

The Look of Qt 4 RC 1

As the first release candidate of Qt 4 has been released it is time to take a good look at the examples and demos supplied along the library and tools. This article consists of a range of screenshots from the release candidate.

The Demos

We start with the affine demo, demonstrating anti-aliased transformated vectorgraphics. Click on any of the screenshots for a full size version.

The next set of images shows the the main window framework. The middle image shows the available settings for the toolbar, while the right-most shows the settings for the dock windows.

The demo showing the possibilities for gradients looks stunning. First, three shots of the different spread methods, followed by three shots of the different gradient types. This makes me wish for a Qt 4 based vector graphics package! The last image shows the in-demo information screen.

The text edit widget has gained many features. The first image shows the capabilites regarding lists and styles, while the other image shows in-line images and the long awaited improved support for tables.

The vector deformation demonstrations looks great! Could this mean that the next generation of the kmagnify tool will look this stunning? :-)

The Interview framework demonstration shows a common selection between a table, a tree and a list along with an explored branch of the tree.

The next pair of shots shows the paths' demonstration.

Finally, a small spreadsheet application is shipped as a demo.

The Examples

The Interview framework examples contains a chart viewer application and the pixelator. Both featuring custom views.

The next image shows the too rarely used syntax highlighter class in action.

Drag and drop is illustrated by a fridge magnet application.

The OpenGL module offers 3D graphics capabilites.

Custom widgets include the animated, colorful wiggly widget and the classical tetrix demonstration.

The painter features are shown in a set of examples including the basic drawing example, the concentric circles demonstration (showing the difference between anti-aliasing and aliased graphics along side ints and floats).

The painter paths example is shown in the two available fill modes, odd/even to the left and winding to the right.

Last, but not least importantly, the classic cannon tutorial is still with us! :-)

Notice that this article does not cover all demonstrations and examples that are shipped with Qt 4 RC 1.
