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 deals with dragging data from your application to another. For simple use, you can assign a TWinControl on your form to the DonorComponent property, detect the drag in the control's OnMouseDown event, and call the Execute method. Appropriate content (e.g., selected text or list items, etc.) is then dragged to the other application. For more sophisticated use, there is a Text property to which you can assign any content you like.
TDMTextTarget deals with accepting data dragged into your application from another. You assign a TWinControl on your form to the AcceptorControl property, and write an OnDrop handler to tell the TDMTextTarget how to deal with the data that has just been dropped. Natively, TDMTextTarget knows how to accept text, RTF, HTML, lists of files, and URLs.
TDMTextTarget is also the component that is used for accepting arbitrary formats other than text, through the use of its CustomFormat property. In the OnDrop event you can find out what formats are available and decide which to process.
Other than the native formats in TDMTextTarget, graphic images are the most commonly requested data types for drag and drop. For convenience, we provide TDMGraphicSource which works just like TDMTextSource, except that it has DonorImage and Picture properties (of type TImage and TPicture, respectively), which correspond to the DonorComponent and Text properties of TDMTextSource. Dragging a picture becomes as easy as assigning it to a property, detecting the drag, and calling Execute.
TDMGraphicTarget can accept pictures dragged from another application. For convenience, it deals with multiple formats like DIBs, bitmap handles, metafiles and enhanced metafiles, so the developer need only provide a home for the TPicture data that is accepted. Of course, there is ample opportunity for customizing the process as with the other components.
DropMaster comes with a collection of more than 40 example applications, which demonstrate the features of the DropMaster components in real-world situations. They also represent the results of extensive research into the drag and drop behavior of many popular commercial applications.
DropMaster comes with complete source code for all components, packages, and design editors at no additional charge. Documentation is provided in an extensive context-sensitive online help system. DropMaster also features one-step installation, automatic help integration and dynamic component registration.
