[CLOSED] Merge cells (Stringgrid)
«
on:
December 04, 2021, 09:09:11 pm »
I found this code to merge cells. It half works, but the cells under the spanned cells are still selecable and the grid lines are visible.
How can I fix this?
Code: Pascal
[Select]
[+]
[-]
procedure
TForm1
.
StringGrid1DrawCell
(
Sender
:
TObject
;
aCol
,
aRow
:
Integer
;
aRect
:
TRect
;
aState
:
TGridDrawState
)
;
var
i
,
x
,
y
:
Integer
;
begin
if
gdFixed
in
aState
then
Exit
;
if
not
(
ARow
in
[
1
,
3
]
)
then
Exit
;
{Draw row 1 with text from cell 1,1 spanning all cells in the row}
with
Sender as TStringGrid
do
begin
{Extend rect to include grid line on right, if not last cell in row}
if
aCol <
Pred
(
ColCount
)
then
aRect
.
Right
:
=
aRect
.
Right
+
GridlineWidth
;
{Figure out where the text of the first cell would start relative to the
current cells rect}
y
:
=
aRect
.
Top
+
2
;
x
:
=
aRect
.
Left
+
2
;
for
i
:
=
1
to
aCol
-
1
do
x
:
=
x
-
ColWidths
[
i
]
-
GridlineWidth
;
{Paint cell pale yellow}
Canvas
.
Brush
.
Color
:
=
$7FFFFF
;
Canvas
.
Brush
.
Style
:
=
bsSolid
;
Canvas
.
FillRect
(
aRect
)
;
{Paint text of cell 1,1 clipped to current cell}
Canvas
.
TextRect
(
aRect
,
x
,
y
,
'A rather long line which will span cells'
)
;
end
;
end
;

See the demo project in folder examples/gridexamples/merged_cells of your Lazarus installation.

Thanks for the pointer.
Turned mcgrid into a component and it works great.
