Re: [Lazarus] ComparePoints func

First start by defining what ComparePoints is supposed to measure or compare. yes, of course: compare source editor x/y positions. Ie, it is CompareCoords. -- Regards, Alexey -- ___ Lazarus mailing list Lazarus@lists.lazarus-ide.org

Re: [Lazarus] ComparePoints func

IMHO you should consider 5 cases: P1 = P2 and the four quadrants https://en.m.wikipedia.org/wiki/Quadrant_(plane_geometry) - Quadrant I should correspond to > - Quadrant III should correspond to < - What about quadrants II and IV? You could compare your point to Y = -X line to reduce your study

Re: [Lazarus] ComparePoints func

What do you think about: function ComparePoints(P1, P2: TPoint): TPoint; begin Result.X := (P1.X - P2.X); Result.Y := (P1.Y - P2.Y); end; Best regards. Sandro Cumerlato On Jul 26, 2017 3:56 PM, "Alexey via Lazarus" wrote: I think LCL has many Compare

No I didn't try that, but I did right now. It locked up my linux. I couldn't even switch to another tty. I'll look into it and possibly file a bug. Thanks. -- ___ Lazarus mailing list Lazarus@lists.lazarus-ide.org

Juha, I just tested on Qt4 (I haven't tested Qt5 yet) and the sparta form designer is working great with the latest svn trunk, with one outstanding problem: TMainMenu is not working correctly with the Qt4 widget set. video
