Download Free/Trial Version Of UnitOOPS OLE Drag and Drop Components
Description. These components provide the Delphi and C++Builder developer with access to most common inter-application(OLE) drag and drop capabilities with almost no user code. And, they trigger events you can handle to get even more control over the dragand drop process. You can drag text, pictures (bitmaps or metafiles) and user-defined data formats to other applications. You can accept plaintext, file lists, rich text (RTF), Microsoft HTML format, URL links, bitmaps, DIBs, metafiles, and user-defined data formats (several at a time, ifnecessary). If you need to drag or accept a new format, you do not need to write a new descendant component; you only need to assignsome values to a property. You can even drag and drop live OLE links. All content is neatly encapsulated in Delphi-style objects (e.g.,graphical content is always in a TPicture, text is always in a Delphi string or TStringList). For dragging from your application, the componentssupport the use of whatever mouse button youchoose. You can even use different mouse buttons to drag different content.Typical usage. You need almost no code to get all of the functionality of drag and drop in your own applications: typically, for example, youddrop a TUOTextTarget component on a form, set a couple of properties, and write literally a line or two of code to do whatever you want withthe content a user drags and drops onto your application. In order to demonstrate this, the source code for a large number sample drag anddrop applications, both Delphi and C++Builder, is available online at <http://www.unitoops.com/uoole/examples>. The help for thecomponents is also available online on our web site at <http://www.unitoops.com/uoole/reference>. A trial version of the components(which will operate only while the Delphi or C++Builder IDE is running) is available for download from the web site, and includes the sourcecode for the sample applications.
