|
|
* This program is used to replicate the Windows desktop and start menu
|
|
* into the native desktop's copies. Desktop entries are merged directly
|
|
* into the native desktop. The Windows Start Menu corresponds to a Wine
|
|
* entry within the native "start" menu and replicates the whole tree
|
|
* structure of the Windows Start Menu. Currently it does not differentiate
|
|
* between the user's desktop/start menu and the "All Users" copies.
|
|
*
|
|
* This program will read a Windows shortcut file using the IShellLink
|
|
* interface, then invoke wineshelllink with the appropriate arguments
|
|
* to create a KDE/Gnome menu entry for the shortcut.
|
|
*
|
|
* winemenubuilder [ -w ] <shortcut.lnk>
|
|
*
|
|
* If the -w parameter is passed, and the shortcut cannot be created,
|
|
* this program will wait for the parent process to finish and then try
|
|
* again. This covers the case when a ShortCut is created before the
|
|
* executable containing its icon.
|
|
*
|
|
* TODO
|
|
* Handle data lnk files. There is no icon in the file; the icon is in
|
|
* the handler for the file type (or pointed to by the lnk file). Also it
|
|
* might be better to use a native handler (e.g. a native acroread for pdf
|
|
* files).
|
|
* Differentiate between the user's entries and the "All Users" entries.
|
|
* If it is possible to add the desktop files to the native system's
|
|
* shared location for an "All Users" entry then do so. As a suggestion the
|
|
* shared menu Wine base could be writable to the wine group, or a wineadm
|
|
* group.
