This one hour presentation will cover some of the more complex areas of QML and present tips, tricks, best practices and common areas of error and confusion. The material is based on real-world experience developing customer applications for mobile, embedded and desktop.
The topics covered will include some or all of the following:
Anchors - QML offers a flexible and useful way of binding properties between objects but, if used incorrectly, can have a negative impact on application performance. For visual items, anchors offer a better implementation option.
Data Models and Views - This will cover support for data models and views in QML including static models, dynamic models, delegates and using C++ models with QML views.
Keyboard Input Handling - QML provides the means to handle keyboard input at either a fine-grained or high level. There is convenient built-in functionality for tab and arrow key navigation and forwarding of input events. The rules defining how keyboard events are processed are simple, but one needs to pay attention to several important details (as well as to the behavior of the built-in QML items) to get the right behavior.
Time will be allotted to answer questions from the audience.
