The Windows version of MeVisLab supports mouse gestures for network interaction.

The use of network gestures can be toggled in the Preferences on the Network Interaction tab: see Section 4.3.8, “Preferences — Network Interaction”.

A mouse gesture is performed by holding the right mouse button down while the mouse cursor is over the network background, and moving the mouse. The trail of the mouse while performing a gesture is rendered on the network for a better orientation.

The trail of the mouse gesture is color coded. If the gesture is not yet recognized, the trail is rendered in a yellow color, on recognizing a gesture the color changes.

The trail is cleared on releasing the right mouse button. No context menu is shown in case of having performed a gesture, not even if the gesture has not been recognized.

A gesture can be reset by pressing ESC while still holding the right mouse button down; the trail so far is then cleared as well.

3.17.1. Gesture for Closing the Current Network

The current network can be closed by a gesture that consists of a stroke down and then a stroke to the right, like drawing the letter 'L'. Once the gesture has been recognized by the system, the trail is rendered in a green color. To complete the command, simply release the right mouse button.

3.17.2. Gesture for Closing the Current Network Without Requester

The current, changed and unsaved network can be close without showing the requester asking whether the network should be saved by a gesture that starts as the gesture before (drawing an 'L'), but with an additional stroke down at the end. Once the gesture has been recognized by the system, the trail is rendered in a blue color. To complete the command, simply release the right mouse button.
