[SOLVED] SynEdit resize text
«
on:
May 29, 2023, 07:38:02 pm »
Hi,
I would like to resize the text in a TSynEdit with mouse scrolling. I have the following but it doesn't work well. If you reduce the size, the text suddenly becomes large again.
Code: Pascal
[Select]
[+]
[-]
procedure
TFrmMain
.
SynEditJsonDataMouseWheelDown
(
Sender
:
TObject
;
Shift
:
TShiftState
;
MousePos
:
TPoint
;
var
Handled
:
Boolean
)
;
begin
if
(
ssCtrl
in
Shift
)
and
Sender
.
InheritsFrom
(
TSynEdit
)
then
begin
TSynEdit
(
Sender
)
.
Font
.
Size
:
=
TSynEdit
(
Sender
)
.
Font
.
Size
-
1
;
Handled
:
=
true
;
end
;
end
;
procedure
TFrmMain
.
SynEditJsonDataMouseWheelUp
(
Sender
:
TObject
;
Shift
:
TShiftState
;
MousePos
:
TPoint
;
var
Handled
:
Boolean
)
;
begin
if
(
ssCtrl
in
Shift
)
and
Sender
.
InheritsFrom
(
TSynEdit
)
then
begin
TSynEdit
(
Sender
)
.
Font
.
Size
:
=
TSynEdit
(
Sender
)
.
Font
.
Size
+
1
;
end
;
end
;
It is for Windows only.

Make sure you don't go through zero.
Negative font sizes are valid values, and the font becomes larger. (IIRC pixels vs points).
SynEdit already has zoom.
add emCtrlWheelZoom to SynEdit.MouseOptions.

I had overlooked that option.
Thanks, zoom now works fine.
