Gantt chart Demo

[adilsonpazzini]

There is some Demo / example in the lazarus referring to the use of "gantt chart"
according to link https://plus.google.com/102234507512662777040/posts/EJ35qRssmLG .

I saw this feature also in ERP Promet, needed an example of how to use, if anyone can help me I thank

As far as I'm aware, there is no gantt chart in the default installation of lcl or fpc.

If you need to quickly raise a Gantt issue, check out this class.
https://github.com/pichugin-m/pk_gtfc
It's not yet a component; it's created through code.

The initial post is almost 10 years old, but maybe it's worth mentioning that TAChart of Laz/main now has a TStateSteries which can be used for a simple Gantt plot (https://wiki.lazarus.freepascal.org/TAChart_documentation#TStateSeries), see demo in components/tachart/demo/stateseries of the Lazarus installation.

If you search the internet, you can find 3-4 possible solutions, but they're all disparate pieces that don't form a cohesive, neat structure. In my opinion, they're a disgrace. They don't allow you to quickly create a live diagram. After looking at the demos, I realized I had to either use VirtualStringTree and train it, or create my own. I actually chose to create my own (the results are above), considering the need for live task manipulation from the canvas.

I know this is an old topic, but I don't like it when search engines return empty topics without solutions.

PS: sorry, I didn't notice that this topic was originally in the TAChart group.
