Members
hwndOwner
Handle of the
owner window. When a file viewer creates a window to display a file, it should
specify this handle as the owner of the window.
iShow
Show command.
For a list of show commands, see the description of the ShowWindow function.
dwFlags
Show
information flags. This member can be a combination of these values:
|
FVSIF_CANVIEWIT |
The file
viewer can display the file. |
|
FVSIF_NEWFAILED |
The file
viewer specified a new file to display, but no viewer could display the file.
The file viewer should either terminate or continue to display the previous
file. |
|
FVSIF_NEWFILE |
A drag and
drop operation has dropped a file on the file viewer window. The file viewer
passes the name of the file to the shell by copying the name to strNewFile.
The shell attempts to load a file viewer that can display the new file. |
|
FVSIF_PINNED |
A pinned
window exists. A file viewer should either use the pinned window to display
the file or set a new pinned window and display the file in it. |
|
FVSIF_RECT |
rect contains valid data. |
rect
Address of a RECT structure that specifies
the size and position of the file viewer s window. This member is valid only if
dwFlags includes the FVSIF_RECT value.
punkrel
Address of an
interface whose Release member function is called by a new file viewer
to release the previous file viewer. This member is used when a drag and drop
operation drops a file on the file viewer s window.
strNewFile
Address of a
string that specifies the name of a new file to display. A file viewer sets
this member when a drag and drop operation drops a file on the file viewer s
window.
The shell
uses this structure to pass information to a file viewer, and a file viewer
uses it to return information to the shell.
