ColorDialog odd behavior
lazarus / 31-LCL

----------------------------------------------------------------------

If I start a ColorDialog and choose right away a color on the right
side (I mean the smooth colors in the right box) by clicking with the
mouse the color is not shown on the colored panel beneath (in my
german version named "Farbe Basis" - should be "Color Basis" in
english).

So, if I close the Box now, the color is not chosen and used in my
program as expected.

Only if I choose a color in the Box on the left side of the
ColorDialog first and afterwards choose one on the right again, the
color is updated as it should be.

I think this is a bug in Lazarus. Does anybody have a workaround for
this?

If I am right and it is a bug. How can I post it to be mended?

Thanks for any help! I am new to this forum.

Add:
As I now discovered this seems to be a normal behavior (same as in
Delphi) of the TColorDialog. I was just irritated by the fact that
choosing a color at the right side doesnt change the lightness from
just black to something lighter. So you just get black if you don't
specify the lightness and then close the dialog.

I'm not sure what the correct behaviour is myself.

To report a bug, use the link for Lazarus -> Bugtracker on the left
hand side of this forum.
ie http://bugs.freepascal.org/view_all_bug_page.php?project_id=1

Also, please read:
http://wiki.lazarus.freepascal.org/How_do_I_create_a_bug_report

UPDATE: Whoops, I missed your update :-)   OK, so if it works the same
under Delphi, it's unlikely to be changed.  And if it works the same
under Delphi, then it's problems an operating system dialog (I'm
assuming Windows), and so unlikely to be fixable.

But, if it's annoying, lodge a bug report.  Someone may be able to fix
it :-)

Thank you for the information on "reporting a bug". Probably it will
be usefull in other cases.

At the right of the color gradient box there is another slider for the
brightness. It is at its minimum for userdefined colors by default,
i.e. all colors are black. Slide it up and you will see the color
appear in the color box ("FarbeBasis"), and OK will select this color.
