for industrial automation and SCADA I have developed an application mixed of Qt widgets and QML using QML 1.0 and QtDeclarative. The QML scenes have a lot of QML items inside like pipes, pumps, valves and tanks. These components have a specific position and size each connected to the other.
You can see a picture "here":http://www.imb-web.de/index.php/fuelcontrolmenu.
The problem is now, that this application needs to run on different resolutions, starting from 1024x768 until full hd resolution.
My question is if there is a technique to resize a complex QML scene so that the items are also resized proportional and also there positions are moved proportional.
I know of property binding but for a complex scene with hundreds of QML items it is not really a solution to calculate all the positions and width and height from the parent size so that it fits at the end.
Also the scaling is not really a solution because the rendering of a scaled scene is rather bad, and especially text is not longer readable.
