vmpk - Man Page

vmpk [options...]

This manual page documents briefly the vmpk program.

This program uses standard Qt options.

Virtual MIDI Piano Keyboard is a MIDI events generator and receiver. It doesn't produce any sound by itself, but can be used to drive a MIDI synthesizer (either hardware or software, internal or external). You can use the computer's keyboard to play MIDI notes, and also the mouse. You can use the Virtual MIDI Piano Keyboard to display the played MIDI notes from another instrument or MIDI file player.

The following options apply to vmpk only:

-h|--help

Displays a help text.

-v|--version

Displays version information.

-p|--portable

Enables portable settings mode using a default configuration file name.

-f path/file.conf

This option implies --portable as well. Reads and writes path/file.conf as the portable settings configuration file name.

This configuration file is always a text file with INI format, despite the running Operating System conventions.

The following options apply to all Qt5/6 applications:

-style= style / -style style

Set the application GUI style. Possible values depend on the system configuration. If Qt is compiled with additional styles or has additional styles as plugins these will be available to the -style command line option.

-stylesheet= stylesheet / -stylesheet stylesheet

Set the application styleSheet. The value must be a path to a file that contains the Style Sheet.

-widgetcount

Print debug message at the end about number of widgets left undestroyed and maximum number of widgets existed at the same time.

-reverse

Set the application's layout direction to Qt::RightToLeft. This option is intended to aid debugging and should not be used in production. The default value is automatically detected from the user's locale (see also QLocale::textDirection()).

-platform platformName[:options]

Specify the Qt Platform Abstraction (QPA) plugin.

-platformpluginpath path

Specify the path to platform plugins.

-platformtheme platformTheme

Specify the platform theme.

-plugin plugin

Specify additional plugins to load. The argument may appear multiple times.

-qwindowgeometry geometry

-qwindowicon icon

Set the default window icon.

-qwindowtitle title

-session session

Restore the application from an earlier session.

-display hostname:screen_number

-geometry geometry

Specify the window geometry for the main window on X11. For example: -geometry 100x100+50+50

-dialogs= [xp|none]

Only available for the Windows platform. XP uses native style dialogs and none disables them.

-fontengine= freetype

Use the FreeType font engine.
