| def grc.gui.elements.FlowGraph.update_selected_elements | ( | self | ) |
Update the selected elements. The update behavior depends on the state of the mouse button. When the mouse button pressed the selection will change when the control mask is set or the new selection is not in the current group. When the mouse button is released the selection will change when the mouse has moved and the control mask is set or the current group is empty. Attempt to make a new connection if the old and ports are filled. If the control mask is set, merge with the current elements.

What is selected? At the given coordinate, return the elements found to be selected. If coor_m is unspecified, return a list of only the first element found to be selected: Iterate though the elements backwardssince top elements are at the end of the list. If an element is selected, place it at the end of the list so that is is drawn last, and hence on top. Update the selected port information.
| coor | the coordinate of the mouse click | |
| coor_m | the coordinate for multi select |
