TcxEditRepositoryImageComboBoxItem Class

An edit repository item that stores image combo box settings.

Declaration

TcxEditRepositoryImageComboBoxItem = class(
    TcxEditRepositoryItem
)

Remarks

An image combo box is a combo box editor that can display images in addition to text in items available for selection.

The TcxEditRepositoryImageComboBoxItem class overrides the Properties property that allows you to access and customize image 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 an Image Combo Box Repository Item at Design Time

To create an image combo box repository item at design time, double-click an edit repository component to invoke its collection editor.

The collection editor dialog allows you to manage repository items. Click the Add… button to invoke a repository item creation dialog.

Select the ImageComboBox item and click the Ok button to create an image combo box repository item.

Create an Image Combo Box Repository Item in Code

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

Delphi

uses cxEdit, cxEditRepositoryItems;
// ...
var
  AImageComboBoxItem: TcxEditRepositoryImageComboBoxItem;
  ARepositoryItem: TcxEditRepositoryItem;
begin
  ARepositoryItem := cxEditRepository1.CreateItem(TcxEditRepositoryImageComboBoxItem);
  AImageComboBoxItem := ARepositoryItem as TcxEditRepositoryImageComboBoxItem;
  AImageComboBoxItem.Properties.Images := cxImageList1; // Assigns an image source (TcxImageList)
  AImageComboBoxItem.Properties.ImageAlign := iaRight; // Aligns displayed images to the right border
  // Assigns the created repository item to two existing unbound image combo boxes
  cxImageComboBox1.RepositoryItem := AImageComboBoxItem;
  cxImageComboBox2.RepositoryItem := AImageComboBoxItem;
end;

C++

#include "cxEdit.hpp"
#include "cxEditRepositoryItems.hpp"
// ...
  TcxEditRepositoryImageComboBoxItem *AImageComboBoxItem;
  TcxEditRepositoryItem *ARepositoryItem;
  // ...
  ARepositoryItem = cxEditRepository1->CreateItem(__classid(TcxEditRepositoryImageComboBoxItem));
  AImageComboBoxItem = dynamic_cast<TcxEditRepositoryImageComboBoxItem*>(ARepositoryItem);
  AImageComboBoxItem->Properties->Images = clImageList1; // Assigns an image source (TcxImageList)
  AImageComboBoxItem->Properties->ImageAlign = iaRight; // Aligns displayed images to the right border
  // Assigns the created repository item to two existing unbound image combo boxes
  cxImageComboBox1->RepositoryItem = AImageComboBoxItem;
  cxImageComboBox2->RepositoryItem = AImageComboBoxItem;

Image Combo Box Repository Item Deletion

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

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