Change in TreeView (treeview.inc)
«
on:
November 27, 2021, 12:06:11 pm »
Hello,
I suggest a little change in the function FindNodeWithText:
Change:
Code: Pascal
[Select]
[+]
[-]
function
TTreeNodes
.
FindNodeWithText
(
const
NodeText
:
string
)
:
TTreeNode
;
begin
Result
:
=
GetFirstNode
;
while
Assigned
(
Result
)
and
(
Result
.
Text
<> NodeText
)
do
Result
:
=
Result
.
GetNext
;
end
;
To:
Code: Pascal
[Select]
[+]
[-]
function
TTreeNodes
.
FindNodeWithText
(
StrtIndex
:
Integer
=
0
;
const
NodeText
:
string
)
:
TTreeNode
;
begin
Result
:
=
TreeView1
.
Items
[
StrtIndex
]
;
while
Assigned
(
Result
)
and
(
Result
.
Text
<> NodeText
)
do
Result
:
=
Result
.
GetNext
;
end
;
If you have 2 (or more) nodes with the same text with a different parent node, you cannot find the next one.

Please post this in the bugtracker and mark it as feature request. The optional parameter must be at the end, though.

Also, since it returns a TTreeNode, maybe it should take a TTreeNode as optional arg?
Code: Pascal
[Select]
[+]
[-]
function
TTreeNodes
.
FindNodeWithText
(
const
NodeText
:
string
;
ContinueAfterNode
:
TTreeNode
=
nil
)
:
TTreeNode
;
Just an idea.
