Hi, I am planning to develop a non linear video system editor (After Effect, Final Cut Like)... The main Widget of this kind of software is the Timeline (composed of layers, in which you can add key frame, and on the left panel you can directly set value of the keyframes). you can see the curve between keyframe, hide layers, ... zoom, unzoom, scroll..
- I have develop similar software years ago : first Qt2 or 3 (don't remenber) : using Qpainter and adding removing visible items in the timeline on the fly... - Then I have do that for another software with QGraphicsView : Easy ! you add all the items in qgraphicsScene And Qt do all the job to manage the large number of items... I have a QtreeWidget to change property of each keyframe on the left... It was working fine ! But when you wants to customize some parts in the QtreeWidget it was not very easy ... - Now I plan to use Qt Quick /Qt5 (I know it's not ready to use now ... but it's a project for next year !) : I plan to replace all the widgets (QTreeWidget/QgraphicsWidget) by a Qml and QAbstractModel : it will be more flexible to use javascript, easier to break rectangular area, effects, .... But How can I do that in QML efficiently ? I will have a large numbers of items ... In short how to code what can be easily and efficiently done with QGraphicsView ? _______________________________________________ Qt5-feedback mailing list [email protected] http://lists.qt.nokia.com/mailman/listinfo/qt5-feedback
