====== Thunar - Advanced Settings ======

While most setting can be configured using the menu and/or the [[preferences|Preferences dialog]], some of the settings are not visible in the interface because they are considered not general enough for the average user.

===== The Settings Editor =====

Open the //Thunar// tab  in the **xfce4-settings-editor** in order to see which settings are currently stored and to modify them. Make sure to quit //Thunar// before with "thunar -q". Otherwise your changes will have no effect.

===== Hidden Settings =====

The hidden settings need to be specifically enabled in the settings channel of Thunar to enable or change their functionality.

Below a table of the settings and the commands on how to enable them.

^ Property ^ Value Type ^ Description ^
| /misc-always-show-tabs | bool | If the view tabs should always be visible. |
| /misc-case-sensitive | bool | Determines whether the sorting should be done in a case-sensitive manner. The default is //false//. |
| /misc-full-path-in-title | bool | Show the full directory path in the window title, instead of only the directory name. |
| /misc-horizontal-wheel-navigates | bool | Controls whether the horizontal mouse wheel is used to navigate back and forth within a Thunar view, or whether it should be used for horizontal scrolling. |
| /misc-image-size-in-statusbar | bool | Show the image size in the statusbar when a single image file is selected in the view. This is disabled by default because it causes relatively high I/O when changing the selection quickly. |
| /misc-remember-geometry | bool | Whether Thunar should remember the size of windows and apply that size to new windows. If //true// the width and height are saved to ''last-window-width'' and ''last-window-height''. If //false// the user may specify the start size in 'last-window-width'' and 'last-window-height''. This option is enabled by default. |
| /misc-small-toolbar-icons | bool | Use small icons on the toolbar instead of the default toolbar size. |
| /misc-tab-close-middle-click | bool | Whether to close tabs when the tab label is clicked with the 2nd/middle-mouse-button. |
| /misc-exec-shell-scripts-by-default | bool | Whether shell scripts should be executed or opened by default. The default action is to open them; setting this to TRUE will allow executing them. |

The quickest way to change a hidden settings is to run a command in the terminal-emulator.

  xfconf-query --channel thunar --property /property-name --create --type value-type --set new-value


So to enable the image size in the statusbar, run the following command:

  xfconf-query --channel thunar --property /misc-image-size-in-statusbar --create --type bool --set true

All hidden settings are boolean values, so the value can either be ''true'' to enable the functionality or ''false'' to disable.

===== Custom CSS =====

For most graphical elements of //Thunar// (and all other gtk3 applications) , it is possible to customize them via CSS, like it is done by themes.

Here an example for //Thunar// 1.8.x (gtk3 based):
  - Create a file ~/.config/gtk-3.0/gtk.css
  - Paste following content in this file:
  - Save and restart thunar (thunar -q; thunar)

  
  * {
     -ThunarAbstractIconView-row-spacing: 70;
     -ThunarAbstractIconView-column-spacing: 30;
   }


For thunar //Thunar// 1.6.x (gtk2 based):
  - Create a file ~/.gtkrc-2.0
  - Paste following content in this file:
  - Save and restart thunar (thunar -q; thunar)

  style "thunar-spaced-out-icons"
  {
     ThunarIconView::column-spacing = 70
     ThunarIconView::row-spacing = 30
  }
  class "ThunarIconView" style "thunar-spaced-out-icons" 
  
Check the [[https://developer.gnome.org/gtk3/stable/chap-css-overview.html|GTK+ CSS Overview page]] to see learn how CSS can be used in gtk3.

Use the  [[https://wiki.gnome.org/Projects/GTK%2B/Inspector|GTK Inspector]] together with thunar to see which properties can be modified on each element.
