Good afternoon,

In an SqlArray i want to change background color for some rows. For instance, in an array with 8 rows, i want rows 2 to 4 with red background then rows 5 and 6 with blue background and the last row with green background. I want to have the possibility to change colors in my program.

I found in the forum that i have to use Display. The documentation talk about ColorDisplay and i have seen something about a Display's function named PaintBackground.

Someone could explain to me how i can use all of these, please?

Thank you very much for your help.

Best regards.

Hi,
you can use SetLineColor:
array.SetLineColor(1, LtRed());
array.SetLineColor(2, LtRed());
array.SetLineColor(3, LtRed());

array.SetLineColor(4, LtBlue());
array.SetLineColor(5, LtBlue());



regards
omari.

Good morning omari,

Thank you for your answer, but the setLineColor function does not exist for SqlArray. I obtain this error message when i compile :

error: 'class Upp::SqlArray' has no member named 'setLineColor'

I had a doubt and i have looked after number of upp's version. I'm sorry for my last response, setLineColor exists but not in the version 9251. Mea culpa, mea maxima culpa.

Rhaaa, many problems with UPP 11873. I use TDM-GCC-64 compiler. If now i see setLineColor function in the IDE, i still have the error message when i compile :

error: 'class Upp::SqlArray' has no member named 'setLineColor'


I don't understand the problem Confused

my guess is that, you have more than one upp installation, and your app is still using the old one.
if your app is in MyApps assembly, please, check your file MyApps.var, verify that the uppsrc is in the new upp version.
here is mine
UPP = "C:\\upp/MyApps;C:\\upp/uppsrc";


Note:
instead of TDM-GCC, you can download upp-mingw-11873.7z, that chipped with a preconfigured mingw64 version.
and instead of the stable version, considere using the nightly build, it is also stable, and up to date.


regards
omari.

Hello patisab,

I agree to omari's suggestion that you should better use the MingGW64 version bundled with u++.

Aside from that, did you check the spelling? U++ does not use the so-called "camel case" notation: There is no setLineColor method in SQLArray. It should be SetLineColor.

Please take your time and read documentation (especially on coding style), it will help you a lot. Smile
