Expression of feedback to make unavailable area clear in drawing lines
Disclosed is representation of unavailable area for a graphical editor. The representation improves usability in edit operation with pointing device. This document consists of the followings: 1. Implementation example 1 2. Implementation example 2 3. Features and Benefits
1. Implementation example1 This example shows how unavailable area appears in dragging a box. In this, a box must not be on the top of other boxes.
State 1(See Figure 1)
For changing location of "}Class4"}, a user drags it and drops where he wants to locate it. While dragging "}Class4"}, a square with dotted line is drawn as feedback. State 2(See Figure 1) When "}Class4"} becomes on the top of "}Class3"}, unavailable area appears and the cursor's shape is changed. While the cursor is in the unavailable area, the drag&drop operation of "} Class4"} is canceled even if a user drops it. The area is displayed until the cursor gets off the area.
2. Implementation example 2 This example shows how unavailable area appears in dragging a connector line. In this, a connector line must not be on the boundary of a box.
State 1, State 2(See Figure 2)
For changing route of a line, a user drags "}P2"} and drops it where he wants to locate it. While dragging "}P2"}, a line "}P2P3"} is re-drawn as feedback.
