Replacing drawing objects when chart is moving/zooming
Posted: Tue Nov 17, 2015 10:45 pm
Hi all,
when I use the drawing tools in a qscript how I can replace my drawing objects (line, rectangle ...) when the chart will be zoomed, moved, scaled or whatever replaces the the candle bars on the canvas. What I mean is that I need a mechanism to move the drawing objects in the same moment when the chart itself moves over the canvas in the correct relation I have placed the drawing objects initially.
Is there something like events for zooming , moving, scaling and so on?
Many thanks in advance.
