Graphic component for Delphi

Job ID: 34777305

Budget: €12 – €18 EUR

I want a graphic component: TTreeView + TGrid + Network chart.

Necessary opportunities:
Drag-n-drop data editing (extend, shorten, crop and transfer rulers with mouse movement).
Ability to change the time scale;
The possibility of convenient customizing of drawing time rulers (by adding code). For example, there was one thick time ruler, and I wanted to draw two different thinner rulers next to each other instead (for example, at first only the duration was drawn, then I wanted to draw both the duration and progress of the project).

The deadlines are not in a hurry, but also without delays.

I am a professional programmer myself, so I can evaluate the quality of the source code, its correctness.
