ElXTree: ElTreeInplaceCheckBox: Which values to use for True and False?

RaymondWKRaymondWK
edited March 2013 in LMD ElPack
The ElXTree has a column with type set to Boolean in the HeaderSections property.

I placed the ElTreeInplaceCheckBox on the form and set the Tree to be my ItemTree.

I left the default value to be '*', because that's what was there when I dropped it on the form.

However, the values of Boolean are True/False or -1/0.

I don't see checkboxes in the column.

What value do I give ItemTree.Items.Item[i].Cells[1].Text so that the cell will display as a checked checkbox?
What value for an unchecked checkbox?

Thanks.

Raymond

    They are shown, when field is in edit mode.

    Maybe here is great misunderstanding. To show checkboxes you use cell controls. 
    A CheckBox inplace editor is used to allow enduser to select between (text) values - using either DefaultConversion (therefore DefaultValueAsText for checked items) or writing an own AfterOperation method for the editor. Example:

    procedure TfrmLMDElXTree_InplaceEdit.ElTreeInplaceCheckBox1AfterOperation(Sender: TObject; var Accepted, DefaultConversion: Boolean);
      if TElTreeInplaceCheckBox(Sender).Editor.Checked then
        TElTreeInplaceCheckBox(Sender).ValueAsText := 'I am checked'
      else
        TElTreeInplaceCheckBox(Sender).ValueAsText := 'I am not checked';
      DefaultConversion := false;
      Accepted := true;
    end;
