Client Usage

This document is the reference about the concepts of the graphical user interface (also known as Tryton client ) of the Tryton application framework.


tryton - Graphical user client of the Tryton application framework


tryton [options] [url]

On startup the login dialog is displayed.



Show program version number and exit

-h, --help

Show help message and exit

-c FILE, --config=FILE

Specify alternate configuration file

-d, --dev

Enable development mode, which deactivates client side caching

-v, --verbose

Enable basic debugging

-l LOG_LEVEL, --log-level=LOG_LEVEL

Specify the log level: DEBUG, INFO, WARNING, ERROR, CRITICAL

-u LOGIN, --user=LOGIN

Specify the login user

-s SERVER, --server=SERVER

Specify the server hostname:port


When an url is passed, the client will try to find already running client that could handle it and send to this one to open the url. If it doesn’t find one then it will start the GUI and open the url itself.

The url schemes are:

tryton://<hostname>[:<port>]/<database>/model/<model name>[/<id>][;parameters]

tryton://<hostname>[:<port>]/<database>/wizard/<wizard name>[;parameters]

tryton://<hostname>[:<port>]/<database>/report/<report name>[;parameters]

where parameters are the corresponding fields of actions encoded in JSON.


model is for act_window


report must have at least a data parameter with ids, id and model name


On startup the login dialog is displayed. It allows to select a existing profile (or to manage them) or to enter the host and database information.

The following schematic illustration of the Tryton client shows the names of all important visual parts.

Tabbed Main Frame

This part of the client contains all the related contents and functions provided by the Tryton server modules. All aspects inside the main frame depend at least on the individual set of activated modules.

The main frame provides a tabbed document interface to arrange different views side by side. New tabs are opened by special actions, like choosing a menu item or clicking some action buttons. All tabs include titles which show the name of the provided view.

Tabs can be arranged by Drag and Drop.


Inside views there can be tabs, too.

Application Menu

The following section describes the action of the application menu. A rule of thumb: All items of the menu bar that are suffixed by three dots (…) will open an intermediate dialog for setting up the provided menu action. Most dialog provide a Cancel button, used to stop the complete dialog process.


The Options menu sets up several visual and context depending preferences.

  • Default: Shows labels and icons as defaulted in the GTK configuration.

  • Text and Icons: Shows labels and icons in the tool bar.

  • Icons: Shows icons only in the tool bar.

  • Text: Shows labels only in the tool bar.

  • Save Column Width: Check box to enable saving of manually adjusted widths of columns in lists and trees.

  • Save Tree Expanded State: Check box to enable saving of expanded and selected nodes in trees/lists.

  • Spell Checking: Check box to enable spell checking in fields.


Tool Bar

The tool bar contains the functionalities linked to the current tab. Some operations are working with one record or with a selection of records. In form view the actual record is selected for operations. In tree view all selected records are used for operations.

There are a several widgets used on Tryton in client side. The follow sections will explains some of them.

Date/DateTime/Time Widgets

These widgets have several key shortcuts to quickly modify the value. Each key increases if lower case or decreases if upper case:

  • y: by one year

  • m: by one month

  • w: by one week

  • d: by one day

  • h: by one hour

  • i: by one minute

  • s: by one second

The = key sets the widget value to the current date and time.

TimeDelta Widgets

This widget represent a duration using different symbol of time separated by space:

  • Y: for years (default: 365 days)

  • M: for months (default: 30 days)

  • w: for weeks (default: 7 days)

  • d: for days (default: 24 hours)

  • h: for hours (default: 60 minutes)

  • m: for minutes (default: 60 seconds)

  • s: for seconds (default: 1 seconds)

The hours, minutes and seconds are also represented as H:M:s.

For example: 2w 3d 4:30 which represents: two weeks, three days and four and an half hours.

The value of each symbol may be changed by the context of the widget. For example, a day could be configured as 8 hours.

Search Widget

The search widget adds the ability to easily search for records on the current tab. This widget is visible only on tree view.

The Syntax

A query is composed of search clauses. A clause is composed of a field name (with : at the end), an operator and a value. The field name is optional and defaults to the record name. The operator is also optional and defaults to like or equal depending on the type of the field. The default operator is = except for fields of type char, text and many2one which is ilike.

Field Names

All field names shown in the tree view can be searched. Field names must be followed by a :

For example: Name:

If the field name contains spaces, it is possible to escape it using double quotes.

For example: "Receivable Today":


The following operators can be used:

  • =: equal to

  • <: less then

  • <=: less then or equal to

  • >: greater then

  • >=: greater then or equal to

  • =: not equal

  • : not equal or not like (depending of the type of field)

For example: Name: != Dwight


The ilike operator is never explicit and % is appended to the value to make it behaves like starts with


The format of the value depends on the type of the field. A list of values can be set using ; as separator.

For example: Name: Michael; Pam

It will find all records having the Name starting with Michael or Pam.

A range of number values can be set using ...

For example: Amount: 100..500

It will find all records with Amount between 100 and 500 included.

There are two wildcards:

  • %: matches any string of zero or more characters.

  • _: matches any single character.

It is possible to escape special characters in values by using double quotes.

For example: Name: "Michael:Scott"

Here it will search with the value Michael:Scott.

Clause composition

The clauses can be composed using the two boolean operators Boolean operations and Boolean operations. By default, there is an implicit Boolean operations between each clause if no operator is specified.

For example: Name: Michael Amount: 100

is the same as Name: Michael and Amount: 100

The Boolean operations operator has a highest precedence than Boolean operations but you can change it by using parenthesis.

For example: (Name: Michael or Name: Pam) and Amount: 100

is different than Name: Michael or Name: Pam and Amount: 100

which is evaluated as Name: Michael or (Name: Pam and Amount: 100)

RichText Editor

This feature create a rich text editor with various features that allow for text formatting. The features are:

  • Bold: On/off style of bold text

  • Italic: On/off style of italic text

  • Underline: On/off style of underline text

  • Choose font family: Choice from a combo box the desired font family

  • Choose font size: Choice from a combo box the desired size font

  • Text justify: Choice between four options for alignment of the line (left, right, center, fill)

  • Background color: Choose the background color of text from a color palette

  • Foreground color: Choose the foreground color of text from a color palette

Besides these features, it can change and edit text markup. The text markup feature has a similar HTML tags and is used to describe the format specified by the user and is a way of storing this format for future opening of a correct formatted text. The tags are explain follows:

  • Bold: Tag b is used, i.e. <b>text</b>

  • Italic: Tag i is used, i.e. <i>text</i>

  • Underline: Tag u is used, i.e. <u>text</u>

  • Font family: It is a attribute font-family for span tag, i.e. <span font-family=”Arial”>text</span>

  • Font size: It is a attribute size for span tag, i.e. <span size=”12”> text</span>

  • Text Justify: For justification text is used paragraph tag p. The paragraph tag is used to create new lines and the alignment is applied across the board. Example: <p align=’center’>some text</p>

  • Background color: It is a attribute background for span tag, i.e. <span background=’#7f7f7f’>text</span>

  • Foreground color: It is a attribute foreground for span tag, i.e. <span foreground=’#00f’>text</span>


The client can be styled using the file theme.css.

Here are the list of custom selectors:

  • .readonly: readonly widget or label

  • .required: widget or label of required field

  • .invalid: widget for which the field value is not valid

  • headerbar.profile-: the name of the connection profile is set on the main window

For more information about style option see GTK+ CSS
