InteractiveTools

Declaration

type TAddPolygonPartTool = class(TAddLinePartTool)

Description

TCustomInteractiveTool is an abstract base class. Its descendants (mainly in InteractiveTools) handle on-screen interaction between the user and the grid or TScreenObjects.

The main procedures in which the interaction is handled are MouseDown, MouseMove and MouseUp. These are called in TframeView.ZoomBoxImage32MouseDown, TframeView.ZoomBoxImage32MouseMove, and TframeView.ZoomBoxImage32MouseUp.

The hints in TfrmGoPhast.frameTopView, TfrmGoPhast.frameFrontView, and TfrmGoPhast.frameSideView are set by the current tool via GetHint, Activate, and Deactivate.
