Qt Diagramming libraries
Are there any Qt-based diagramming libraries available to buy or as open source?
I mean something a little more than drawing every element and their connections one by one...
Hi and welcome
You mean something like http://www.qcustomplot.com ?
Or what you mean by
" a little more than drawing every element and their connections one by one" ?:)
Explain what you want to draw and perhaps someone can provide information on that.
Is it graphs or diagrams like UML?
I have looked around actually, I think it shouldn't be too hard to code this but a starting point would be good...
Actually I have never seen such a library.
What I have done in the past (3 years ago) was to draw some elements connected to each other using Qt Quick (QML) and it worked pretty good.
Another option is to look at the new modelling plugin that will be part of Qt Creator 3.6. And since Qt Creator is open source, you can look at how it is done and perhaps use that as a starting point.
