Posted in Dev Loop, Performance, Qt, Qt Quick, Qt Quick Controls

Since announcing research on Qt Quick Controls optimized for embedded use, we’ve made good progress towards achieving feature parity with the original Qt Quick Controls. We’ve also added some new controls that didn’t exist (Drawer, RangeSlider, and SwipeView, to name a few). The previous blog post cited performance reasons as the motivation for having one fixed style. However, we […]

Qt Weekly #21: Dynamic OpenGL implementation loading in Qt 5.4

Published Thursday November 27th, 2014 | 15 Comments on Qt Weekly #21: Dynamic OpenGL implementation loading in Qt 5.4
Posted in Graphics, OpenGL, Qt Quick, Windows

In Qt 5.4 there is a new configure option on Windows: -opengl dynamic. This, in addition to -opengl desktop and -opengl es2, changes the OpenGL implementation (and implicitly the window system interface API) that Qt is built against.

Qt Weekly #6: Sorting and filtering a TableView

Published Wednesday April 16th, 2014 | 5 Comments on Qt Weekly #6: Sorting and filtering a TableView
Posted in Qt Quick | Tags:

The QtQuick Controls TableView offers a variety of ways to provide data. Supported data model types include the traditional QAbstractItemModel derivative models, QObjectList, JS arrays, and even plain numbers. This flexibility imposes an unfortunate limitation that TableView doesn’t know how to sort arbitrary data models. TableView merely offers a visual enabler, a sort indicator, and […]
