Summary0001647: JvInspectorColorItem: List height fix proposal/question
DescriptionI finally fixed the item list painting issue (list not being a multiple of item height) in ColorItem, it requires a change in TJvCustomInspectorItem.DropDown as follows:

    if TListBox(ListBox).IntegralHeight then
      ListBox.Canvas.Font := TListBox(ListBox).Font;
// change begin (declare _h: Integer; somewhere)
      _h := CanvasMaxTextHeight(ListBox.Canvas);
      DoMeasureListItem(ListBox, -1, _h);
      TListBox(ListBox).ItemHeight := _h;
// change end

The problem is that

// oldcode begin
    TListBox(ListBox).ItemHeight := CanvasMaxTextHeight(ListBox.Canvas);
// oldcode end

will return a value that is too small for color items.

Additionally, you need to remove iifOwnerDrawListVariable in TJvInspectorColorItem.SetFlags()


    inherited SetFlags(Value + [iifValueList,
                             - [iifOwnerDrawListVariable]);

I'm aware of the fact that calling DoMeasureListItem(x, -1, _h) might be a problem, but I don't know a better way to do it.
TagsNo tags attached.
