(SOLVED) TStringGrid merge 2 colors

[xinyiman]

Hello guys, i have a problem. If you compile the example you will see that in two cells of a StringGrid'm going to split the cell into two colors: green and gray.

I actually wish that the gray is merged with the green to make it look like the green area is disabiliitata. Just I do not understand how. If I draw first one and then the other me overlaps, it makes a merger. How can I fix? Thank you

Not idea?

Sure, the method is color blending and it is used extensively on alpha blending with a 255 steps of blending with 0 is pure color 1(or green in this case) and 255 is pure color 2 (or gray in this case)

Can you tell me where I find an example?

Replace filling the two rectangles:

Code: Pascal  [Select][+][-]

1.       Brush.Color := RGB(160,160,160);
2.       FillRect(LRct);
3.  
4.  
5.  
6.       Brush.Color := clGreen;
7.       FillRect(RRct);

with filling the main rectangle:

Code: Pascal  [Select][+][-]

1.       GradientFill(aRect, RGB(160,160,160), clGreen, gdHorizontal);

Check the attached image.

Ok, thanks a lot, but your example is gradually fade the color in another. What you need to me it is being able to make it look like a colored cell of a grid as if it was disabled. So for example, if a cell has all the green background it must seem dull green or semi-transparent. In short, a color that distinguishes it from any valid cell.

To be clear I would get something similar to the pictures that I attach
