This class represents current app and provides app wide APIs.
This class can not be created by user, you can only receive its global
instance from the
app property of the module:
Set the name of current app.
The app name should be something like "My App", it will be used in vairous places, such as folder name when storing user data, or key name when writing registry.
You should always call this API at the beginning of your app.
On macOS it is strong recommended to use the same name with the
CFBundleName field of app bundle's
Return current app's name.
app.setName(name) has never been called, this API will try to guess a
name from existing information, for example the executable's version info,
or the app bundle information, or the executable file's base name.
Set the application ID.
The application ID must be globally unique, and it is recommended to use something like "org.myself.myapp".
On macOS the application ID is the app bundle ID, and there is no way to change it at runtime.
On Linux the application ID will be used in various places, such as the
name of the
or the base name of GSettings schemas.
On Windows the application ID is
it is mainly used to recognize which app a process belongs to. For
UWP/Desktop Bridge apps, Windows will assign an AppUserModelID to the app
and this API should not be used.
Return the application ID.
On macOS if the app is bundled, the app bundle ID will be returned, otherwise empty string will be returned.
On Linux the ID set by
setID will be returned.
On Windows the
will be returned. If neither you or Windows ever assigned an ID to the
app, empty string will be returned.
Set the application menu bar.
Return the application menu bar.
label to be displayed in dock’s badging area.
Get the label displayed in dock’s badging area.
Return whether app is running as UWP/Desktop Bridge.
On Windows the Win32 apps can run as UWP apps by using Desktop Bridge, which is required for submitting Win32 apps to Microsoft Store.
There are a few runtime differences when running apps as UWP, and this API can be used to detect the environment.
Create a start menu shortcut for current user linking to current process.
This API will write the
ToastActivatorCLSID to the
shortcut file, and the shortcut file's name will be the app's name, so it
is recommended to call
app.setName(name) before using this API.
Note that on Windows you should generally not write start menu shortcut automatically, by convention the file is commonly created by installers or users themselves. This API is usually used for testing purpose.
Return file path to the shortcut created by the
Make current app the active app.
force parameter is normally set to false. When the Finder launches
an app, using a value of false for
force allows the app to become active
if the user waits for it to launch, but the app remains unobtrusive if the
user activates another app. Regardless of the setting of flag, there may
be a time lag before the app activates—you should not assume the app will
be active immediately after sending this message.
Deactivate current app.
Return whether current app is the active app.
Modify the app's activation policy.
Return app's activation policy.
