The top-level items in the tree are processes. If you have traced more than one process on the target system, you can switch between them by selecting them in this view. Selecting a process causes the Trace view to only display calls for that process.

Function calls are further grouped depending on the API in use. For example, OpenGL ES calls are grouped into frames and render passes. For each item in the tree, including the groupings, the name, index, and extra interesting information for that item are shown. For certain items, extra information can be found in the tooltip for the item.

Selecting an item in the tree causes other views to be updated to provide information about that item. Selections that are made in the Trace view, Breadcrumb bar, or the Statistics view Charts tab cause the selection in the Trace Outline view to update. If the item selected in another view is not an item in the Trace Outline view, a selection line indicates where the item would be.

When you have a trace with many frames, you can use the Show Only Frames With Features Enabled option to quickly find interesting frames. With this mode turned on, only frames that meet one of the following criteria are shown:

• Frame Capture
• Fragment Count
• Overdraw Mode
• Shader Map Mode

To collapse all the items in the tree, click Collapse All.

Right-clicking on items in the tree allows you to generate a diff report between two items and export framebuffers. See 4.6 Comparing state between function calls and 5.11.1 Exporting assets for more information.

Each call that is executed in a different EGL context is highlighted using a different color.
