在Delphi中的TreeView中保存多个数据
使用Delphi几年后,居然不知道还可以这么用,惭愧呀
type
PMyRec = ^TMyRec;
TMyRec = record
FName: string;
LName: string;
end;
procedure TForm1.Button1Click(Sender: TObject);
var
MyRecPtr: PMyRec;
TreeViewIndex: LongInt;
begin
New(MyRecPtr);
MyRecPtr^.FName := Edit1.Text;
MyRecPtr^.LName := Edit2.Text;
TreeViewIndex := StrToInt(Edit3.Text);
with TreeView1 do
begin
if Items.Count = 0 then
Items.AddObject(nil, 'Item' + IntToStr(TreeViewIndex), MyRecPtr)
else if (TreeViewIndex < Items.Count) and (TreeViewIndex >= 0) then
Items.AddObject(Items[TreeViewIndex], 'Item' + IntToStr(TreeViewIndex), MyRecPtr);
end;
end;
procedure TForm1.Button2Click(Sender: TObject);
begin
Label1.Caption := PMyRec(TreeView1.Selected.Data)^.FName + ' ' +
PMyRec(TreeView1.Selected.Data)^.LName;
end;
PMyRec = ^TMyRec;
TMyRec = record
FName: string;
LName: string;
end;
procedure TForm1.Button1Click(Sender: TObject);
var
MyRecPtr: PMyRec;
TreeViewIndex: LongInt;
begin
New(MyRecPtr);
MyRecPtr^.FName := Edit1.Text;
MyRecPtr^.LName := Edit2.Text;
TreeViewIndex := StrToInt(Edit3.Text);
with TreeView1 do
begin
if Items.Count = 0 then
Items.AddObject(nil, 'Item' + IntToStr(TreeViewIndex), MyRecPtr)
else if (TreeViewIndex < Items.Count) and (TreeViewIndex >= 0) then
Items.AddObject(Items[TreeViewIndex], 'Item' + IntToStr(TreeViewIndex), MyRecPtr);
end;
end;
procedure TForm1.Button2Click(Sender: TObject);
begin
Label1.Caption := PMyRec(TreeView1.Selected.Data)^.FName + ' ' +
PMyRec(TreeView1.Selected.Data)^.LName;
end;
