Lasso Selection Demo

This demo shows how to use LassoSelectionInputMode to select graph elements by drawing a lasso around them.

Things to Try

• Selection Styles: Choose between different selection styles:

  • Free-hand Selection: Draw a free-form shape around elements by dragging the mouse.
  • Polyline Selection: Create a polygon by clicking to add points. Double-click to complete the selection.
  • Marquee Selection: Use the traditional rectangular selection by dragging the mouse.

• Select Nodes: Choose how nodes are considered selected by the lasso tool:

  • Nodes Complete: Nodes are selected only if fully contained within the lasso path.
  • Nodes Intersected: Nodes are selected if they intersect or are fully contained within the lasso path.
  • Nodes Center: Nodes are selected only if their center point is contained within the lasso path.

• Finish Radius: Adjust the radius around the starting point where the lasso can be closed. When dragging the lasso near the starting point, a circle with the corresponding radius is highlighted.
