我找到了一个很好的组件来实现ComboBox的Caption< - >值列表:
Is there a ComboBox that has Items like a TcxRadioGroup?
唯一的问题是:它有一个Sorted属性,但不起作用。
那么,我如何对TcxImageComboBox的项进行排序?
答案 0 :(得分:3)
快速而肮脏的方法,对大多数情况应该可以正常工作:
function CompareItems(AFirst: TcxImageComboBoxItem; ASecond: TcxImageComboBoxItem): Integer;
begin
Result := AnsiCompareText(AFirst.Description, ASecond.Description);
end;
procedure SortCxComboBoxItems(AItems: TcxImageComboBoxItems);
var
I : Integer;
J : Integer;
PMin : Integer;
begin
AItems.BeginUpdate;
try
// Selection Sort (http://en.wikipedia.org/wiki/Selection_sort)
for I := 0 to AItems.Count - 1 do
begin
PMin := I;
for J := I + 1 to AItems.Count - 1 do
begin
if CompareItems(AItems[J], AItems[PMin]) < 0 then begin
PMin := J;
end;
end;
if PMin <> I then
begin
AItems[PMin].Index := I;
end;
end;
finally
AItems.EndUpdate;
end;
end;
