&dhprg; Virtual MIDI Piano Keyboard
&dhprg; options...

## DESCRIPTION

This manual page documents briefly the &dhprg; 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.

## vmpk Options

The following options apply to &dhprg; 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.

## Standard Options

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

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

`-qwindowicon` icon

  Set the default window icon.

`-qwindowtitle` title

  Set the title of the first window.

`-session` session

  Restore the application from an earlier session.

`-display` hostname:screen_number

  Switch displays on X11. Overrides the `DISPLAY` environment variable.

`-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.
