doMouseMove method
void
doMouseMove()
Move the #draggedParts (or if copying, the #copiedParts) to follow the current mouse point.
If this creates any temporary parts, by default it adds them to the Tool layer.
This calls #doDragOver for any side-effects on stationary parts.
Implementation
void doMouseMove() {
_i4.callMethod(
this,
'doMouseMove',
[],
);
}
