VCL Editors Library: A Color Combo Box Example

The TcxEditRepositoryColorComboBox class overrides the Properties property that allows you to access and customize color combo box settings.

Edit Repository Items and Standalone Editors

Edit repository items are useful when you need to share the same settings between multiple editors of the same type. To accomplish this goal, you can assign the same edit repository item to RepositoryItem properties of all target editors.

Edit Repository Items and Container Controls

A container control item (such as a toolbar edit item or a column (or any other data item) in a Data Grid, Vertical Grid, or Tree List control) can embed an in-place editor shipped with the ExpressEditors Library. An in-place editor exists (and, therefore, has its own WinAPI handle) only when the target container control item is being edited. Otherwise, the container control item displays a static editor image for resource usage optimization.

Create a Color Combo Box Repository Item in Code

The following code example creates a color combo box repository item, customizes color combo box settings, and assigns the created repository item to two existing unbound color combo boxes:

uses cxEdit, cxExtEditRepositoryItems;
// ...
var
  AColorComboBoxRepositoryItem: TcxEditRepositoryColorComboBox;
  ARepositoryItem: TcxEditRepositoryItem;
begin
  ARepositoryItem := cxEditRepository1.CreateItem(TcxEditRepositoryColorComboBox);
  AColorComboBoxRepositoryItem := ARepositoryItem as TcxEditRepositoryColorComboBox;
  // Allows users to select custom colors
  AColorComboBoxRepositoryItem.Properties.AllowSelectColor := True;
  // Aligns color boxes to the right border
  AColorComboBoxRepositoryItem.Properties.ColorBoxAlign := cbaRight;
  // Assigns the created repository item to two existing unbound color combo boxes
  cxColorComboBox1.RepositoryItem := AColorComboBoxRepositoryItem;
  cxColorComboBox2.RepositoryItem := AColorComboBoxRepositoryItem;
end;

Color Combo Box Repository Item Deletion

To delete all color combo box repository items in a TcxEditRepository component, call its RemoveItems procedure and pass a reference to the TcxEditRepositoryColorComboBox class as a parameter.

If you need to delete an individual color combo box repository item, release it directly in code (call the Free procedure in Delphi or use the delete keyword in C++Builder).
