Viewing and Editing Dependencies

Dependency lines on the Gantt chart give you a visual overview of how tasks connect. GlidePath renders these lines in real time as you add or change links.

Reading Dependency Lines on the Gantt

​

Line Appearance

​

Direction and Arrows

Each dependency line runs from the predecessor task bar to the successor task bar:

• FS: Line exits the right end of the predecessor, enters the left end of the successor
• SS: Line exits the left end of the predecessor, enters the left end of the successor
• FF: Line exits the right end of the predecessor, enters the right end of the successor
• SF: Line exits the left end of the predecessor, enters the right end of the successor

​

Hover to Highlight

Hovering over a dependency line:

1. Highlights the line in a brighter color
2. Highlights both the predecessor and successor task bars
3. Shows a tooltip with the relationship type and lag value

This makes it easy to trace chains of dependencies in complex schedules.

​

Showing and Hiding Dependency Lines

Use the Dependencies toggle buttons in the toolbar:

• Show Critical: Display only critical-path dependency lines
• Show All: Display all dependency lines
• Hide: Hide all dependency lines (useful for printing or dense schedules)

​

From the Gantt Line (Click)

1. Click on a dependency line
2. A small popup appears showing the relationship type and lag

4. Modify the type or lag, then click Save

​

From the Task Right-Click Menu

Viewing All Dependencies for a Task

To see every link connected to a specific task:

2. The Predecessors field lists all predecessor task IDs and relationship types
3. Successor relationships are visible when you open dependent tasks

​

Predecessor Column

Enable the Pred column in the Gantt task list to see each task’s predecessors inline:

1. Click Columns in the toolbar
2. Check Predecessors
3. Each task row shows its predecessor IDs (e.g., 3FS, 7SS+2d)
