Detailed Description
Represents an installed application.
To obtain a KService instance for a specific application you typically use serviceByDesktopName(), e.g.:
Other typical usage would be in combination with KApplicationTrader to obtain e.g. the default application for a given file type.

◆ aliasFor()

static |
Find an application by the name of its desktop file, not depending on its actual location (as long as it's under the applications or application directories).
For instance "konqbrowser" or "kcookiejar". Note that the ".desktop" extension is implicit.
This is the recommended method (safe even if the user moves stuff) but note that it assumes that no two entries have the same filename.
- Parameters
-
_name the name of the configuration file
- Returns
- a pointer to the requested application or
nullptr
if the application is unknown. Very important: Don't store the result in a KService* !

It's usually better to use serviceByStorageId() instead.
- Parameters
-
_path the path of the configuration file
- Returns
- a pointer to the requested application or
nullptr
if the application is unknown. Very important: Don't store the result in a KService* !

static |
Find a application by its menu-id.
