Visual user interface designer for qt4.
Qt Designer simplifies the process of designing and creating graphical user interfaces (GUI) using the award-winning Qt toolkit. Qt Designer is easy to learn. There are tutorials, walkthrough examples and the reference documentation accelerating you through the learning phase. After that, Qt Designer greatly reduces the time and effort needed to develop even the most complex dialogs with an easy-to-use GUI and an integrated help system.
Qt Designer provides a rich set of features aimed at making the creation of dialogs as easy and smooth as possible without reducing the power of Qt. It offers all the strength of the Qt layout system with a well-designed user interface. This, combined with the Qt Designer's undo/redo system makes it simple to try different arrangements of the widgets until the result satisfies you.
Using Qt Designer's convenient property editor along with the dynamic Qt property system it is easy to set the initial state of your widgets. Special editors for some widgets (like listboxes, comboboxes, etc.) allow you to fill these widgets with content without writing any code. Using the object hierarchy view, the parent-child relationship between the widgets of a dialog can be understood at a glance.
Integrating dialogs into a Qt project is straightforward thanks to the User Interface Compiler (UIC), which generates C++ code from the XML dialog description on the fly. The programmer can easily extend the functionality of the generated classes by subclassing without touching generated code at all or running the risk of loosing their changes.
