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

RaymondWK

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.

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;
