Buttons & StringGrid - bugs or features ?

Hi,
I have two questions.
1, TButton or TBitBtn: When Button. Enabled=False then is not possible
do Click. O.K. But OnMouseDown and OnMouseUp methods works. Is it
normal or bug?

2, TStringGrid: I have StringGrid and I have defined for example 5
columns via Columns property. All of them are ReadOnly=True. When I
set global option  goEditing=True for my StringGrid, then is not
possible edit any column, because they are ReadOnly, expect the very
last one (here it is the fifth). I think it's bug.

Lazarus with Qt 4.5 widgetset on Kubuntu 9.04 64bit.

Thanks for help
B.

Qt sends event and propagate it to LCL - so if it's bug then it is
inside qt.

I just tested the same with GTK2.

1, Buttons don't generate OnMouseDown & OnMouseUp methods. So this
problem seems to be only with Qt.

2, There are also the bug with the last StringGrid column, when
goEditing is true and ReadOnly is true, it is possible to write to
cells.

Is it on bugreports? And where would I post them?

Thanks
B.

it's fixed in lazarus rev 22437, thanks for reporting.
Next time, please use the bug tracker
http://bugs.freepascal.org/main_page.php bugs reported on forums are
easy to be missed.

Thanks for fix, I see in rev. 22450 StringGrids work fine,

but I have one more question about Buttons.

I downloaded Qt Creator and made little test with Qt 4.5.3. In world
of CPP are signals press, release instead of our OnMouseDown and
OnMouseUp methods, but in simple app. made in Qt Creator disabled
button doesn't generate any of these signals.
So does exist some solution on this? It's not critical for me, but it
would help.

Thanks for help.
