doActivate method
void
doActivate()
Start reshaping, if #findToolHandleAt finds a reshape handle at the mouse down point.
If successful this sets #handle to be the reshape handle that it finds and #adornedLink to be the Link being routed. It also remembers the original link route (a list of Points) in case this tool is cancelled. And it starts a transaction.
Implementation
void doActivate() {
_i4.callMethod(
this,
'doActivate',
[],
);
}
