TJamSystemShellView Class

A TJamSystemShellView control looks and behaves like the right pane of the Windows Explorer.

Syntax

Pascal

TJamSystemShellView = class(TJamShellControl, IOleWindow, IShellBrowser, IJamShellControl, ICommDlgBrowser, ICommDlgBrowser2);

File

JamSystemShellView

Remarks

This control displays the contents of a folder in a ListView like control. It is a true instance of the right pane of the Windows Explorer and therefore looks and behaves exactly like the Windows Explorer on the system it is running on. In contrast to that, the TJamShellList is derived from the Windows ListView common control and just mimics the right pane of the Windows Explorer. While the TJamSystemShellView looks and behaves more similar to the Windows Explorer on the target system, the TJamShellList offers more control on the appearance and actions.

You can switch between the ViewStyle Details, Small Icons, Large Icons, List and Thumbnails. It also supports the background context menu.
