===== Add New Launchers =====
Besides adding launchers with the [[add-new-items|Add New Items]] window, it is also possible to drag-and-drop ''.desktop'' files straight onto the panel. A common way to do this is by finding the desired application in [[:xfce:xfce4-appfinder:4.18:start:|Application Finder]], and then dragging it from the list and onto the panel.

<note tip>If you try to drop it in between two existing launchers, Xfce will attempt to open the ''.desktop'' file with the nearest application. To prevent this, hold down **Ctrl** as you drag and drop the item.</note>

----

===== Arguments =====
All launchers accept ''text/uri-list'' as arguments when dropped on the launcher button, it will be used as an argument for the first application in the items list. See the [[:xfce:xfce4-panel:4.18:launcher#expanding_variables|Expanding Variables]] below for more information.

The **General** tab offers options down the right hand side for manipulating the selected item.

? Move up / Move down

? Edit the currently selected item
! Opens up an [[:xfce:exo:4.18:desktop-item-edit#editing_launchers|Edit Launcher]] window.

! Deletes the item from the list. If there is only one item, the launcher on the panel becomes blank.
? Add one or more existing items to the launcher
! Opens an Add New Item window with a list of all installed applications. Additional items added are displayed under a list accessible by an arrow that appears next to the launcher. If more than one items are present in the launcher, the first one that appears in the list is used as the primary target.
? Add a new empty item
! Opens a [[:xfce:exo:4.18:desktop-item-edit|Create Launcher]] window to create a new item for the list.

===== Expanding Variables =====

Each launcher's command is expanded before it is executed, meaning the .desktop files' field codes are processed. [[http://standards.freedesktop.org/desktop-entry-spec/latest/|See the specification]] for more details.

Below are some sample variables:

<code>
%F
%f
%U
%u
%i
%c
%k
%%
</code>

----

===== Plugin Events =====

It is possible to send events to launcher plugins over the command line. One example is this:

  xfce4-panel --plugin-event launcher:disable-tooltips:bool:true

This will disable the tooltips property for all launcher plugins in the panel.
