animation - Qt 5.9.0 QML How to Animate an Image with more than 256 colors (ie not a GIF) using AnimatedImage or otherwise -


i can use animatedimage works on gifs this;

import qtquick 2.7 import qtquick.controls 2.2  applicationwindow {     visible: true     width: 640     height: 480      rectangle      {         width: animation.width;          height: animation.height + 8          animatedimage          {             id: animation;             source: "myanimation.gif"         }          rectangle {              height: 8             width: animation.currentframe/animation.framecount * animation.width             y: animation.height             color: "red"              component.oncompleted: console.log("framecount ", animation.framecount);         }     } }

i lot of error messages too. printed on , over;

qqmlexpression: expression qrc:/main.qml:26:20 depends on non-notifyable properties:     qquickanimatedimage::framecount

i took example code here; http://doc.qt.io/qt-5/qml-qtquick-animatedimage.html

which doen't work @ all, wrong putting framecount property, changed in version.

i animate png apng. apparently there used mng support, not there anymore.

so call qmovie::supportedformats returns gif (on windows).

my question:

how can either use animatedimage on format supports non-palettised color (eg png etc) or there way animate image work?

thanks info.

it seems image formats not shipped standard installation of qt/qml. can install them plugin.

python - Best design pattern for collection of objects -

i have following architecture: +-----------------+ | collection | | | | | | | | | +-----------------+ | ^ | | create() | | | | v | getitem(b) +------------+ | | item | | | | | | +------+ | | +------------+ a class managing collection of items, creates items. , these items may need other items collection. the actual code in python, , collection passes parameter created item . see it, bad practice. improvement can see pass few functions of collection needed item , instead of whole instance. for example: class collection: getitem(self, id): ... createitem(self, id): item = item(id, self) # <-- pass self ... class item: __init__(self, id, col): ... col.getite...
