TRect Trouble..

Hi, I have recently finished making my first ever component called TExtLabel. It basically, so far, shows any text with a very accurate and neat border around it; at least I thought so.

After looking at the output a few times I noticed that the furthest left and furthest right pixel was being cut-off and made some characters look a little blocky. I have tried to fix the problem but everything I do will not work.

I have included full source and the DPK file here:
http://www.inspire-fx.com/TExtLabel.zip

If anyone could maybe fix my source so that it shows the extra pixel on both left and right sides of the label I will award the points. :)

Thanks very much, Nat.

hello Krakken, I looked at your code, and it seems that you are trying to Draw outside the controls paint area, so I added some code to expand the area of the control on the auto size for text, but I really did not see the "Left side" pixel not there, so All I did was increase the Right side of the control so the DrawText for offset rect to Right will have something to draw on - - - -



(Code removed at the request of the questioner because it is the code of the questioner.  I have saved the code for future reference only in the event it comes up again

if you still have Left side problems, then you might adj that as well

Yes the left pixel is still missing. Sorry it only shows on certain fonts.

I can't seem to fix this either.

you may want to increase the amount that you add to the Controls width, I used 3 pixels but 4 or 5 pixels may be better??

also you may want to change

if (rctFla and DT_CALCRECT <> 0) and ((Length(Caption) = 0) or
  ShowAccelChar and (Caption[1] = '&') and (Length(Caption) = 1)) then sText := ' ';

to

if (rctFla and DT_CALCRECT <> 0) and ((Length(Caption) = 0) or
  ShowAccelChar and (Caption[1] = '&') and (Length(Caption) = 1)) then Exit;

since there is no text drawn with a Space

and leave out the sText altogether and just use Caption
DrawText(Canvas.Handle, PChar(Caption),
