Command-Line Parameters

QLC+ supports a number of command line parameters to automate/extend some functionalities on startup.
Using command line parameters can be tricky depending on the operating system you're using:


-c or --closebutton

Description: Define a position for a close button in the virtual console. The button can be used to close QLC+. Only has an effect in kiosk mode (see -k) and is most useful when in fullscreen mode without a window manager.

Parameters: x,y,w,h

Examples:
Create a button at (x400, y500) whose size is (w70, h50):
qlcplus -c 400,500,70,50
qlcplus --closebutton 400,500,70,50

-d or --debug

Description: Enable debug mode and optionally set the output level. Note that since 4.8.0 messages for level DEBUG (0) are not included in released binaries.

Parameters: Level (see QtMsgType)

Examples:
Enable debug mode and set debug level to 0:
qlcplus -d
qlcplus --debug

Enable debug mode and set debug level to 3:
qlcplus -d 3

-f or --fullscreen

Description: Start the application in fullscreen mode

Parameters: Method (either 'normal' or 'resize')

Examples:
Tell the window manager to give the whole screen space to QLC+:
qlcplus -f
qlcplus --fullscreen
qlcplus -f normal
qlcplus --fullscreen normal

Resize QLC+ to take up the whole screen space (useful in custom X11 sessions without a window manager):
qlcplus -f resize
qlcplus --fullscreen resize

-g or --log

Description: Log debug messages to a file ($HOME/QLC+.log)

Parameters: None

Examples:
Enable debug messages and store them to log
qlcplus -d 0 -g
qlcplus --debug 0 --log

-h or --help

Description: Display command-line help (only in Linux & OS X)

Parameters: None
