Internal GUI

From Navit's Wiki
Jump to: navigation, search

The Internal GUI is designed to be used on touch screen devices, but also work very well on other devices such as netbooks and laptops. It is under continual development and as such features are constantly being added and improved upon. If you think that a particular feature is missing or poorly implemented, come talk to us in the irc channel or open up a feature request on the trac system.

Configuring Internal GUI

Enabling Internal GUI

The Internal GUI is configured as the default GUI for Navit, so if you're reading this after a first install no further configuration is required.

If the configuration has changed since first install, the Internal GUI can be chosen by setting the type attribute in the <gui> tag.

<gui type="internal" enabled="yes">

Ensure that any other gui tags are disabled by setting their enabled attribute to "no".

Keyboard Preferences

Some options inside the Internal GUI menu require keyboard input - for example, Town search. By default, Navit provides a custom on-screen keyboard to enter text. If your device has it's own keyboard which you'd prefer to use, and you'd like to conserve some screen space then set the keyboard attribute to "false" inside the <gui> tag.

<gui type="internal" enabled="yes" keyboard="false">

Map-click Preferences

By default, the menu appears when the map is clicked. This can be disabled by adding the following to the <gui> tag:

menu_on_map_click="0"

This of course means that you now can't access the menu by clicking on the map. Instead you will have to add an OSD item with the command gui.menu(), as shown in the example below:

<osd enabled="yes" type="button" x="-100" y="290" command="gui.menu()" src="gui_active.png"/>

You can use the following example to enable/disable the menu_on_map_click behaviour from an OSD#button:

<osd enabled="yes" type="button" x="-70" y="290" command="gui.menu_on_map_click=!gui.menu_on_map_click" src="gui_active.png"/>

Icon and font sizes

You can also configure the icon sizes used in the menu. The syntax is as follows:

<gui type="internal" enabled="yes" font_size="250" icon_xs="48" icon_s="48" icon_l="64">

font_size is off course the font size, icon_xs is the size of the green "ticks" you see here. icon_s is the size of the world and home icon and of the icons in the POI selector. Finally, icon_l is the size of the icons defined in the menu html. The icon sizes need to be available as files in Navit (they should be by default).

Menu Configuration

Using Internal GUI, the menu can be brought up by clicking (almost) anywhere on the map, or pressing the Enter (Return) key on the device's keyboard.

The menu is configured using a html-like syntax inside the <gui> ... </gui> tags. Of course, this configuration can be customised - alternative configurations can be found in Internal GUI/Menu configurations.

Initial Start-up

N810-OSD-Home.png

When Navit is first started using the Internal GUI one should see (depending on the skin you have selected to use) something similar to the image to the right. The layout of the internal GUI is controlled by the OSD tags located in the navit.xml file. These tags should be located within the first 100 lines of the file. For information on how to modify the appearance of the OSD layout please reference this link. OSD Layout

Using the Internal GUI

Basics and breadcrumbs

The Internal GUI should be mostly self-explanatory (that's the idea, at least - if it is not, please file a bug). It basically consists of different screens which show icons that can be clicked / touched, lists (such as search results) and input fields. For text input, a virtual keyboard is available. Of course, a regular hardware keyboard can be used if available.

On all screens of the Internal GUI, there is a breadcrumb trail at the top of the screen, which shows the current position inside the screen hierarchy of the Internal GUI. The breadcrumbs are clickable, to return to an earlier screen.

Operation with keyboard or rotary encoder

While the Internal GUI is mainly designed to be used with a mouse or touch screen, it can also be operated using a (hardware) keyboard or even a rotary encoder (which only offers "forward", "backward" and "enter").

The GUI elements can be navigated using arrow keys, and activated using Enter, as usual. Additionally, all GUI elements can also be reached using only PgUp/PgDown - this allows the use of a rotary encoder, if its actions are mapped to these two keys.

When using a rotary encoder (or cursor keys), it may be useful to set option hide_impossible_next_keys<tt> to hide irrelevant keys when searching. See the full list of options for details.

Support for rotary encoders was added in December 2015, and hide_impossible_next_keys in February 2017.

Main Menu

InternalGui-MainMenu.png

The main menu is accessed by a single click (or tap for touch screen) anywhere on the map. From here all other sub-menus and actions are accessible. The sub menu items are:

  1. Actions
  2. Settings
  3. Tools
  4. Route
  5. About


Actions

InternalGUI-Actions.png

The Actions menu brings up several sub menus that are focused primarily on routing and location finding. The sub menu items are:

  1. Bookmarks
  2. Former destinations
  3. Map Point
  4. Current Location
  5. Town
  6. Quit - Closes Navit


Bookmarks

InternalGUI-Bookmarks.png

Bookmarks provide a convenient way to store often used destinations. Since Navit does not fully support entering a complete address using OpenStreetMap maps, a user can locate some oft-used destinations on the map and then add that point as a bookmark. That way the next time the user would like a route for that particular destination the user only has to select it from the Bookmarks menu and does not have to go through the tedium of panning the map and zooming into the destination location.

Bookmarks can be arranged hierarchical using / as a separator - anything before the separator becomes the folder name; anything after the separator becomes the bookmark name. For example, if you name your bookmarks Friends/Joe and Friends/Bill, you will have a folder named Friends and the bookmarks Bill and Joe in there.

A fully functioning bookmark editor is currently not available, though some common edits can be performed from within the Bookmarks menu. Bookmarks are stored in a plain-text bookmarks file in your Navit directory (~/.navit on unix systems).

Former destinations

A list of the last destinations that were set in Navit. Every time a destination is set (via a bookmark, via a map point or by searching for an address and choosing it as a destination), the destination will be added to this list.

The list of former destinations is a convenience feature, to quickly reuse a destination. The functionality offered is similar to the Bookmarks menu (however, the list cannot be edited, as it is meant as a record of the destinations selected).

To prevent the list from getting too long to be useful, only the last 10 destinations are kept. This limit can be changed in navit.xml (attribute "recent_dest" in element "<navit>"). So normally, each time a new destination is selected, it will be added to the list, and the oldest entry in the list will be discarded. As an exception, if a destination is set that is already in the list, it will not be repeated in the list; instead the entry will just be moved to the top.

Map Point

InternalGUI-MapPoint.png

The world icon brings up the Map Point sub menu for actions that can be performed for the point that was selected on the map. The items contained in this sub menu are:

  • Set as Destination: Will generate a route to that location from either current GPS data or where vehicle position is manually set (see Vehicle Position).
  • Set as Position: If no GPS data is available then you can specify your "current" location in order to have a route generated from that position to your desired destination.
  • Add as Bookmark: Brings up a keyboard so a name can be entered for the bookmark. The point can then be easily recalled via the Bookmark menu.
  • POIs: Brings up a list of all known POIs around the map point.


POIs
InternalGUI-POIs.png

The POIs sub menu shows all of the POIs that are close to the location that was clicked on the map, with the distance to the POI shown in kilometres. At the top of the menu there are various filter options that allow for specifying the types of POIs to be displayed. The user can click on the POI and select to be routed to that location. Navit will create a route from the current position to the location of the POI selected.

Vehicle Position

InternalGUI-VehiclePosition.png

The vehicle icon brings up the Current Location sub menu. This sub menu allows for various actions to be taken for the GPS position of the device.

  • Set as Destination: Will generate a route to that location from either current GPS data or where vehicle position is manually set (see Vehicle Position).
  • Set as Position: If no GPS data is available then you can specify your "current" location in order to have a route generated from that position to your desired destination.
  • Add as Bookmark: Brings up a keyboard so a name can be entered for the bookmark. The point can then be easily recalled via the Bookmark menu.
  • POIs: Brings up a list of all known POIs around the map point.
  • View on Map: Re-pans the map to display the current "known" position based upon GPS data.


Town

InternalGui-Town.png

The town icon allows for searching for different cities within your map set. Note that Navit attempts to auto complete the town name based upon names available in the mapset being used. On slow devices this can result in a slight pause as each character is typed in. Once a town is located and selected another sub menu will come up allowing for a street to be found within that town.

The icon in the upper left corner (just below the world icon) shows the current country which is being searched. To change the country just click on the icon and another menu will appear allowing you to select the country you would like to search in. Note that this menu also attempts to auto complete as the user types in the name of a country.

Note that if you compiled Navit yourself there can be issues with the icons not being properly generated. This will result in no icon image at all. If you have this problem check your logs to see what is happening during compiling.

If you are having problems with search, please check OpenStreetMap#Problems_with_OSM_and_navit_or_navigation_in_general.

Settings

InternalGUI-Settings.png

The settings menu provides several sub menus to enable certain aspects of how Navit operates to be modified. Note that at this time there is only a limited set of options that can be changed through these sub menus. In order to change settings not currently available in this sub-menu it is necessary to modify the navit.xml file. At some point in the future a more robust settings menu will be implemented that will allow for configuring Navit through a GUI instead of the navit.xml file.

The sub menu items are:

  1. Display
  2. Maps
  3. Vehicle
  4. Rules


Display

InternalGUI-Display.png

The display sub menu provides items to control various display features within Navit.

  1. Layout
  2. Fullscreen/Window Mode
  3. 3D


Layout
InternalGUI-Layout.png

Layout allows for different layouts specified in the navit.xml file to be shown on the map. Different layouts can be used for different reasons including allowing one to see other friends position (if their GPS data is specified in the layout tag). Note that layout options MUST be enabled in the navit.xml file before they can be turned on or off in this menu.

Window Mode (Toggle)

Changes Navit from windowed mode to fullscreen mode and vice versa.

3D (Toggle)

This is a toggle button that enables / disables drawing the map in either a 2D mode or a 3D mode. Currently the only way to modify the "tilt" for the 3D mode is to modify the navit.xml file.

Maps

InternalGUI-Maps.png

Displays the maps that are specified in the navit.xml file and allows for activating/de-activating those maps. Note that a map must be enabled in navit.xml before it will appear in this menu.

Vehicle

InternalGUI-Vehicle.png

Brings up a menu showing what GPS device is currently being used for the current vehicle. Tapping the GPS device name opens a menu with available routing profiles.


Rules

InternalGUI-Rules.png

The rules menu provides for options that change how Navit behaves when there is a satellite lock. Note that some of these items are currently not function and must be changed in the navit.xml file.

Tools

The tools menu allows the user to check what Locale Navit is set to.

Route

InternalGUI-Route.png

The route icon brings up the route menu that will display the active route.

  1. Route Description
  2. Height Profile, requires a dedicated binfile to providing heightlines.


Route Description

InternalGUI-RouteDescription.png

The route description sub menu displays all of the directions for the currently calculated route.
