Experimental feature request: "Snap to object" (sticky selection?) mode #64

Closed dmitrypuzyrev closed 1 year ago

The idea is to decrease the required operations (and mouse clicks) during correction by the following:

introduce a "snap to object" mode which can be toggled by a button (for example g)
in this mode, the rod which is closest to the mouse pointer is automatically selected (dynamically, i.e. moving mouse around the picture changes the selected rod). The distance to rod center could be tried first.
by this, one extra click needed to select the rod before editing the endpoints could be usually removed.

A prototype of this mode is now available on the viewing_efficiency branch. @dmitrypuzyrev: Please evaluate, whether this is what you intended when writing this issue.

@DrMole0815 It actually work well and seems to be quite intuitive! It only need to be toggleable + there seems to be a small bug that changes the thickness of the selected rod to 1.

@dmitrypuzyrev: The mode is already toggleable in the View menu as the action Autoselect rods. There is no shortcut assigned to it though.

The changed rod thickness was no bug but rather part of the implementation of @KirstenHarth's and @mahmoham's request for keeping the previous rod displayed during editing. I have now changed that to keep the line thickness and rather increase the transparency during editing.

The Autoselect rods mode can now be toggled using G as the shortcut.
