InsertLink by code with breakpoint?

[HPW]

When I want to insert a link by code between 2 nodes but with a breakpoint, what is the way to go?

Code: Select all

function InsertLink(Source, Target: TGraphObject; ALinkClass: TGraphLinkClass = nil): TGraphLink;

function InsertLink(Source: TGraphObject; const Pts: array of TPoint; ALinkClass: TGraphLinkClass = nil): TGraphLink;

function InsertLink(const Pts: array of TPoint; Target: TGraphObject; ALinkClass: TGraphLinkClass = nil): TGraphLink;

function InsertLink(const Pts: array of TPoint; ALinkClass: TGraphLinkClass = nil): TGraphLink;


The first version only links directly.
Does the versions with the Start/end-Pts link to a node which can be found there?

Directrly use TGraphLink.CreateNew constructor.

Oops, I missed it.
Thanks for the info.

I am trying to do this, but currently a bit struggled to build the array dynamicly:

Code: Select all

VAR
    ptarray      : array of TPoint;


    ....
    J := 1;
    FOR I := 0 TO ArrayCount DO
     BEGIN
      pt := point(....);
      ptarray[J] := pt;
      Inc(J);
     END;


Giving me access-violations.

I finally managed it with:

SetLength(ptarray, acount);
