TPJCBView is a non-visual Delphi VCL component that notifies the user whenever the content of the clipboard changes.
Notification is by means of an event. By handling the event your application can respond to changes on the clipboard. The component can be used as the heart of a program that displays "live" information about the clipboard. Alternatively it can be used to enable and disable other components whose state depends on the available clipboard formats.
TPJCBView provides an Enabled property that is used to enable and disable the component and hence it's events. It also has a TriggerOnCreation property that triggers an event when the control is created.
For more information see the component's online documentation.
The component must be compiled with Delphi 7 or later. It is 32 bit an 64 bit compatible.
The unit has dependencies on the VCL and on the Windows API, so cannot be used with the FireMonkey framework or with non-Windows targets.
The Clipboard Viewer Component and its associated files are supplied in a zip file. Before installing you need to extract all the files from the zip file, preserving the directory structure. The following files will be extracted:
PJCBView.pas– component source code.PJCBView.dcr– component palette glyph.README.md– this file.CHANGELOG.md– project change log.MPL-2.txt– the Mozilla Public License v2.0.Documentation.url– short-cut to the component's online documentation.
In addition to the above files you will find the source code of a demo project in the Demo sub-directory.
The component can be installed into the Delphi IDE by including PJCBView.pas and PJCBView.dcr in some suitable package(s). If you need help doing this see here.
The source code of a program that demonstrates the component is included in the download.
This demo requires Delphi 7 as a minimum.
For more information about the demo see the file DemoReadMe.txt in the Demo directory.
A complete change log is provided in CHANGELOG.md that is included in the download.
