Description

The Drag and Drop Component Suite is a freeware VCL component library that enables your Delphi and C++Builder applications to support COM based drag and drop and integrate with the Windows clipboard.

The drag and drop system that is built into the VCL, is limited in that it only supports drag and drop within the same application. If you need to drag data from your application to other applications (e.g. Word, Explorer or Outlook), or if you need to be able to accept data dropped from other application (e.g. the Explorer), you have to use COM based drag and drop. COM based drag and drop is an integral and very important part of the Windows user interface and the Drag and Drop Component Suite makes it very easy to leverage all the features of COM based drag and drop in your own Delphi and C++Builder applications.

Every drag and drop operation involves two objects: A drop source and a drop target. The drop source provides the data to be dragged, and the drop target accepts the dragged data.

Likewise there are basically two sets of components in the Drag and Drop Component Suite; Drop source components and drop target components. Most of the source and target components are specialized to handle just one type of data, but a few of the components supports a wider range of data types or are completely generic.

In addition to the drag and drop components, the Drag and Drop Component Suite also includes components that can be used to build Windows Shell Extensions.

Description

When dragging files in Windows Explorer you can hold down the Control or Alt key to make a copy or a shortcut to the file rather than just moving it. The mouse cursor changes appropriately to indicate which operation you are performing. This component duplicates that functionality when doing drag/drop operations in Delphi.

Description

DropMaster is a set of 4 native VCL controls for use in Delphi and C++Builder. While the VCL components included with Delphi and C++Builder permit drag and drop between windows in the same application, DropMaster allows developers to add support for drag and drop between applications. The drag and drop can be between the developer's new application and existing applications such as the Microsoft Office suite, a web browser, etc., or between two custom-written applications.

DropMaster's functionality is divided according to whether you want to allow the user to drag from his application to elsewhere, i.e., a drag source, or from elsewhere to his application, i.e., a drop target. In addition to the actual drag and drop functionality, the components expose several events that allow the developer to get feedback on the drag and drop process while it is happening, or to modify it.

The 4 DropMaster components are: TDMTextSource, TDMTextTarget, TDMGraphicSource, TDMGraphicTarget.

Description

LMD NG Drag&Drop is a part of Next Generation (NG) package suite. All these packages are based on new IDE and language features of latest Delphi IDE versions. NG Drag&Drop provides the ability to exchange data with other applications via standard Windows OLE drag&drop protocol. There are a lot of common applications, which uses Windows drag&drop:

• Windows Explorer (shell) - allows to drag/receive real or virtual file objects.
• MS Office application (Word, Excel, Outlook, ect), WordPad, other text editors - allows to drag/receive ANSI, Unicode, RTF and HTML text data, images, metafiles, files.
• Internet Browsers (Internet Explorer, Google Chrome, ect) - allows to drag/receive URLs (to open new page or as a bookmark), text (as search query to open new page), files (as downloads).
• Adobe Photoshop - allows to drag/receive images.
• many other high quality Windows applications actually support drag&drop.

NG Drag&Drop provides Fluent Interface API, which is an easy and very convenient way for supporting drag&drop operations, without placing any component on the form. API supports both source and target parts.

Description

Highlight with blinking Drop control(s) at form(s) when Drag&Drop operation took place. When dragging is started from a source, all controls, which can accept this drag source becomes blinking. The components search for drag target in whole application object, so source and target can be inserted at different forms. One should pay attention to definition OnDragOver event in target(s) in the case when returned value variable CanAccept depends upon X,Y coordinate of dragging object. TFindTarget sends -1,-1 values for X,Y. In the case returned value of variable CanAccept has to be settled True. Another requirement: DragMode must be equal dmAuthomatic value.

Description

Five components are included in this pack. The three major ones enable applications to support Windows Explorer file drag and drop operations. The remaining two subsidiary components link to and filter the files dropped on one of the primary components. The components are:

• TPJDropFiles: This windowed component catches files dropped anywhere over its window. It can act as a container for other components.
• TPFormDropFiles: This non-visual component catches files dropped anywhere on its form, including the non-client areas.
• TPJCtrlDropFiles: This non-visual component catches files dropped on an associated TWinControl or TFrame.
• TPJExtFileFilter: When linked to a TPJDropFiles or a TPJFormDropFiles this component filters dropped files by extension. One or more extensions can be provided.
• TPJWildCardFileFilter: Like TPJExtFileFilter except that it filters based on a DOS-style wild-card string.

In addition to the above an abstract base class is provided from which developers can derive other filter components.

Key features of TPJDropFiles, TPJCtrlDropFiles and TPJFormDropFiles are:

• An OnDropFiles event is triggered when files are dropped.
• The names of dropped files are made available through the Files array property. For convenience, the name of the first such file is also stored in the FileName property.
• The list of dropped files can be configured to include only files, only folders or all files and folders.
• Dropped folders can be recursed so that all the files and sub-folders in each of the dropped folders are listed.
• Filters can be applied to the dropped files and folders. This is done either by linking to a filter component (see above) or by handling the OnFileFilter event and deciding which files and folders to pass through the filter in the event handler.
• The mouse co-ordinates where the files were dropped can be retrieved, as can a reference to any control under the mouse cursor at the time.
• The OnBeforeDrop event can be used to perform pre-processing before the files are actually dropped.
• The IsFolder array property tells if the equivalent item from Files array is a file or a folder.
• The owning window can be brought to the front when files are dropped.
• Some design time assistance is provided by component and property editors.

A OpenHelp compatible help file is included that integrates with the OpenHelp system of Delphi 3 to 7. The help file can be used independently of the Delphi 2005 and 2006 IDEs with some loss of functionality.

The components are also documented in a wiki

Two demo programs are included in the download. The first exercises both drop files components and the related file filtering components. The second shows how to use TPJCtrlDropFiles with frames.

Description

By adding this small Delphi component to your form, you can accept the files which are dropped from Windows Explorer to your form. You can also specify which file extensions are allowed.

Dragging and dropping files from the Windows Explorer on your application form, can not be implemented with the standard events like OnDrag and OnDrop. You need to capture some Windows messages (WM_DROPFILES) and call some API functions like DragQueryFile and DragFinish. This component has encapsulated them all. You only have to add it to your form and implement the OnDrop event.
