Launchers are buttons which reside in your
Panel and start an application or execute a
command when clicked. A launcher can use any icon and has a
customized tooltip to display a message when the cursor is passed
over the launcher.
You can change a launcher's properties, such as the icon it uses
and its name, by right-clicking on the launcher and selecting
Properties... from the pop-up menu. This
brings up the Launcher properties dialog,
shown in Figure 7. A similar dialog is
used when you create a new launcher (see the section called Adding objects to the panel). Note that internally GNOME makes no distinction
between menu items and launchers: these are just different
representations of the same thing. You can place any menu item on a
Panel, and it will appear as a
launcher. Therefore, all the information below applies equally to
launchers and menu items.
The Laucher Properties dialog has two tabs:
Basic and Advanced. In
the Basic tab, you can set:
Name — this is the application
name, for example, GNOME
terminal. This name will be used if you later
put this launcher in a menu.
Comment — this is a brief
explanation of what this application does, for example,
Terminal emulation program. This will
be used for tooltips.
Command — the actual command that
runs the application, for example,
gnome-terminal.
Type — should be
Application; do not change it unless
you want to create something other than an application
launcher.
Icon — this is the icon which
will be used to represent the launcher in the
Panel. If no icon is specified, a
default icon will be used. To change the icon, just click on
it to launch the icon browser.
Run in Terminal — this specifies
whether the application should be run inside a terminal. If
the application doesn't create any windows on its own, check
this button. If you are unsure, leave it unchecked.
The Advanced properties tab is shown
below. It is intended for advanced users; most of the time, you
will not need to change any of these settings.
Figure 8. Launcher Advanced Properties Dialog
In the Advanced tab, you can set:
Try this before using — you can
enter a command here, and GNOME will check if this command
can be executed. If the command cannot be successfully
executed, the launcher (or menu item) will not be shown even
if you added it to a Panel or
menu. It is mostly used by people preparing GNOME
distributions. For example, the default GNOME Main
Menu contains an item for the
TkRat e-mail program, but you
will only see this item if you have
TkRat installed on your system.
Documentation — currently not
used.
Name/Comment translations — here
you can set translations of the Name
and Comment to other languages. For
example, for GNOME Terminal, the
translations to Spanish (es) are name: Terminal
UNIX de GNOME and comment: Emulador
de terminal GNOME. This means that if a user
sets his language to Spanish during login (this can be done
by selecting the desired language from
Languages menu of the GNOME
Display Manager when logging in) he will see
Terminal UNIX de GNOME in the
menu and Emulador de terminal GNOME as
the tooltip. The actual command that runs the terminal is
unchanged.
To add a new translation, enter the language 2-letter code
and translations of Name and
Comment fields in the empty fields
under the list of current translations, and press the
Add/Set button. To change one of
existing translations, select the row from the list, edit
the fields you want to change, and press the
Add/Set button. To remove one of
existing translations, select it in the list and press the
Remove button.
All of the changes you make in the Launcher
Properties dialog will take effect when you press
Apply or
OK. Pressing OK
closes the dialog; pressing Apply will
allow you to continue editing.
