TcxCustomEditButtons.Items Property

Provides indexed access to all editor buttons in the collection.

Declaration

property Items[Index: Integer]: TcxCustomEditButton read; write; default;

Property Value

Type	Description
TcxCustomEditButton	An editor button. To access all public API members of a stored editor button, cast the Items property value to the TcxEditButton or TdxBreadcrumbEditButton class. Tip You can call the Items.ClassName function to identify the actual editor button type.

Remarks

Pass an index as the Index parameter to access the corresponding editor button in the collection. Use the Count property to identify the number of buttons accessible through the Items property.

Code Example

The code example below demonstrates OnButtonClick and OnCreate event handlers.

The application form’s OnCreate event handler creates two additional embedded buttons in a TcxButtonEdit control and configures the appearance and behavior of all embedded buttons. The OnButtonClick event handler associates all created buttons with the editor’s functionality.

Note

This example uses a TcxImageList component with three SVG icons as a source of glyphs for the created buttons.

Delphi

procedure TMyForm.cxButtonEdit1PropertiesButtonClick(Sender: TObject;
  AButtonIndex: Integer);
var
  AEditor: TcxButtonEdit;
begin
  AEditor := Sender as TcxButtonEdit;
  if AButtonIndex = 0 then  // The first button clears the editor
    AEditor.Clear
  else if AButtonIndex = 1 then  // The second button selects content
    AEditor.SelectAll
  else if AButtonIndex = 2 then  // The third button hides or reveals content
  begin
    if AEditor.Properties.EchoMode = eemNormal then
      AEditor.Properties.EchoMode := eemPassword
    else
      AEditor.Properties.EchoMode := eemNormal;
  end;
end;

procedure TMyForm.FormCreate(Sender: TObject);
var
  AProperties: TcxButtonEditProperties;
  I: Integer;
begin
  cxButtonEdit1.ShowHint := True;  // Enables hints for the editor
  AProperties := cxButtonEdit1.Properties;
  AProperties.BeginUpdate;  // Initiates the following batch change
  try
    AProperties.Images := cxImageList1;  // Assigns the source of button glyphs
    // Create two additional buttons
    AProperties.Buttons.Add;
    AProperties.Buttons.Add;
    // Specify common button settings
    for I := 0 to AProperties.Buttons.Count - 1 do
    begin
      AProperties.Buttons.Items[I].Kind := bkGlyph;  // Changes the button content type to "glyph"
      AProperties.Buttons.Items[I].ImageIndex := I;  // Specifies image indexes in the source list
      AProperties.Buttons.Items[I].HotTrackMode := TcxEditButtonHotTrackMode.Editor;
    end;
    // Specify unique button settings
    AProperties.Buttons.Items[0].Hint := 'Clear';
    AProperties.Buttons.Items[1].Hint := 'Select All';
    AProperties.Buttons.Items[2].Hint := 'Hide/Reveal';
    AProperties.Buttons.Items[2].LeftAlignment := True;
    AProperties.Buttons.Items[2].Transparent := True;
  finally
    AProperties.EndUpdate;  // Calls EndUpdate regardless of the batch operation's success
  end;
end;
