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:

Linux: just open a terminal and type "qlcplus" followed by the parameters you need
Windows: create a shortcut of qlcplus.exe (usually located in C:\QLC+) on your desktop. Right click on the shortcut and select "Properties". In the "Target" field you will see something like C:\\QLC+\\qlcplus.exe. There you can add command line parameters. When done click OK.
For example, to force the German language at startup, modify your shortcut command line like this:

OSX: This is the most difficult case since QLC+ on OSX is bundled into a DMG package. You need to open a terminal and "cd" into the QLC+ DMG like this: cd QLC+.app\\Contents\\MacOS
When done, type "qlcplus" followed by the parameters you need

-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
