Panel

Panels

In a software context, panels are windows, dialogs or similar generic interface elements which are presented to the user. Panels can either be small prompts or dialogs which facilitate an inquiry or message towards the user, or they can be larger, more complex interface components containing multiple texts and/or elements.

Panels in the Tygron Platform

In a project, panels are a term specifically used for a user-defined interface element, which can be created and configured in the editor. Panels are purposefully left generic and abstract. The contents are entirely left open for a project- or template-specific implementation. A panel can be placed inside the 3D World, where its location is indicated by a pop-up icon, which has to be clicked on to reveal the hidden panel. Panels can also be opened via client events or even left idle.

Most panels render HTML-content, which means they can display text without additional formatting. Further layout and styling can be implemented by using HTML, CSS, and JavaScript. This enables panels to also be opened in a web browser or included in the rendering of a web interface.

Panel types

There are 5 types of panels available in the Tygron Platform.

Panel type	Description	Functioning
Text panel	Its contents are defined directly as text.	The text is interpreted as HTML-content and directly displayed as content of the panel. If it is HTML-formatted content, it will be displayed according the specified styling.
Web panel	Its contents are defined by a URL (web address).	The web page to which is referred constitutes the content of the panel. When attempting to open the panel in a web browser, the web page will be accessed directly (i.e. not via the Tygron Platform).
Global panel	One or more globals are linked to this panel, allowing an end-user to edit the values of those globals during a session.	The panel has a predefined structure in the session interface and a fixed location. For each linked global an input field with that global's value is displayed. This value can be altered and submitted by the end-user in the session. The value of the global will be changed accordingly. This panel does not have an HTML-representation, hence it can neither be opened in a web browser nor can it be integrated in the web interface.
Excel panel	Its contents are defined by an Excel file.	Each time data in the project or session are updated, the Excel file is recalculated. The results are interpreted as (HTML-formatted) text and displayed as such. Effectively, this panel is similar to a text panel, but rather than a static definition of the text content, the definition is dynamically generated through the spreadsheet.
Template Excel panel	This is not a panel in itself, but forms a definition by which panels can be generated automatically. The "instances" produced by a template panel behave the same as their 'regular' counterparts.	Based on how the template panel is defined, a number of "instances" of the panel will be generated. Configurations, such as the size, model, and attributes of the panel are carried over directly. The panel name, the assigned stakeholder and certain queries from the Excel file are modified based on what the template panel is applied to.

Properties of panels

Panels have a number of properties which can be configured in the editor. They also allow for the definitions of arbitrary attributes.

Property	Description
Name	When a panel is opened, its name is displayed at the top, telling the end-user what the panel is about.
Sizing	The size of the panel can be adjusted, so that it fits the content well. It is also possible to set the location of the panel within the interface.
Availability	When the panel is placed in the 3D world, it can be set to either be visible or invisible. If it is set visible, it can also be told whether to draw attention or not. The panel can also be made only accessible to a specific stakeholder or a selected group of stakeholders.
Visualization	When the panel is placed in the 3D world, its corresponding pop-up icon is that of a green tick mark. However, there is selection of different icons available from which one can be chosen. The selected icon has both a 3D representation as well as a 2D representation for higher zoom levels and for the web interface.
Overlay	A panel, in itself, may not provide all the information the user wishes to show. If its content is related to specific geographic information that belongs to a certain overlay, the panel can be coupled to that overlay. Whenever the panel is opened in the future, the coupled overlay will be applied simultaneously.
Content	The core functionality of panels is displaying their content. Depending on the type of panel, the type of content can differ. In general, a panel without content has no purpose.

Attributes

Panels can have any number of arbitrary attributes, which allows for additional data to be attached to them in an accessible and versatile fashion. Some attribute names are reserved and have a special function.

Attribute	Unit	Description
ATTENTION	boolean	Whether the panel is drawing attention. This is an attribute representation of the attention property. Changing this attribute causes the panel to draw attention or not.
COLOR	color	The color of the 2D icon of the panel's popup. This can be used to differentiate popups from one another. An additional effect of different colors is that when you zoom out to the 2D view, icons of different colors are not combined.
POPUP_TYPE	nominal integer	The model of the panel's popup. Changing this attribute changes the icon of this popup.
SCALE	decimal value	The size of the 2D icons of the panel's popup in the 3D world. Note that the size is only updated when the visibility of the panel is updated. Either because it is (re)placed in the world, or the visibility is toggled.
VISIBLE	boolean	Whether the panel is visible. This is an attribute representation of the visibility property. Changing this attribute causes the panel to become visible or invisible.
VISIBLE_TIMEFRAME	integer	Starting from which timeframe this panel should be visible. VISIBLE should be set to 1, otherwise the panel is not shown at any timeframe. This dynamic visibility of the panel is applied when viewing a weather effect. The visualisation and division of timeframes is automatically derived from Water Overlays present in the project.

Answers

A panel can be given "Answers". These are buttons that are added to a panel, which allow an end-user to close it by selecting a specific response or option. These answers can be further enriched by adding events to them. When the user views the panel, and they select an answer with one or more events attached to it, the events are fired and changes can be effected in the session.

Use-cases for panels

Information

The most obvious use for panels is to provide information to the end-user. By making a panel accessible, any text or images displayed on it provide a source of (static) content in the session. Especially text panels and web panels are used primarily for this purpose, but especially excel panels can provide information, even dynamically, about the current state of things in the session.

Interaction

Panels can offer options to interact with the session as well. Either answers can be added to a panel, or the html content can define buttons which send instructions to the project via the API. With some work, it's possible to define complex interactions with the 3D world via panels. Text, web, and excel panels can all be used with answers. Text and excel panels can most easily be used to add html buttons and input elements as well.

Calculation model

By not placing the panel anywhere in the world, and not making the panel otherwise accessible by the end-users, it is possible to add a calculation model to a project without "unintended" side effects. For example, if a project requires a dynamic traffic model, an excel panel can be added to the project, with an excel sheet with the appropriate calculations and queries. It would use SELECT queries to retrieve information from the project, use some calculation to determine the appropriate amount of traffic in the various locations in the 3D world, and then use UPDATE statements to change the traffic intensities in the 3D world. By placing this calculation model in an unreachable panel, no stakeholder will see any trace of this calculation model, other than the changing traffic intensities.

Web interface

Main article: Web interface

In the web interface functionality, it is possible to enrich the web interface with your own html, css, and javascript, to provide the functionality you want to the end-users experience. Panels provide the primary means of adding your own information and programming.

The right panel for panels in the editor.

Name

The field for the "name".

The name of the panel. You can change this by altering the text in the "Name" field.

Panel Layout

The fields for the location.

The location of the panel, in pixels of distance from the bottom-left corner of the screen. "-1" places the panel in the default location. You can change this by changing the value in the first input field for the horizontal location, and the second input field for the vertical location.

Panel Width & Height

The fields for the size.

The size of the panel, in pixels. The size set is the outer edge of the panel, there is some distance between the outer edge and the edge of the content placed in the panel. You can change the size by changind the value in the first input field for the width, and the second input field for the height.

Visible

The checkbox for visibility.

Whether the panel's popup should be visible in the 3D world. If the panel has a location in the 3D world, and the panel is visible, a popup is present in the 3D world, clickable by the end-user. If the panel has no location in the 3D world, or is not set to be visible, the panel's popup is not visible in the 3D world.

Request Attention

The checkbox for attention.

Whether the panel's popup should draw attention in the 3D world. If the panel has a location in the 3D world, and the panel is visible, and the panel draws attention, an arrow will appear for the end-user indicating where the panel is.

Assign to Specific Stakeholder

The checkbox and dropdown for the panel's stakeholder.

Whether the panel is only available to one stakeholder, or to all. If the checkbox is unchecked, the panel is available to all stakeholders. If checked, only the stakeholder indicated in the dropdown can see or access the panel. Other stakeholders will not be able to see the panel in the 3D world. If another stakeholder attempts to open the panel, for example via the web interface, they will get an error message that they are not allowed to access the panel.

Model

The model to use for in-map visualization.

The model used for the panel's popup. The model consists of both a 3D model for most zoom levels, and a 2D icon for the higher zoom levels and the web interface. Change the selection in the dropdown to change the used model and icon.

Overlay

The overlay to activate when the panel is opened.

When the panel is opened, this overlay should be activated to provide (additional) geographical information to the end-user. If set to "NONE", no overlay is used. Change the selection in the dropdown to change the used overlay.

Point in 3D World

The options to assign the panel to a geographical location.

A panel can be given a location in the 3D world. To do so, select "Set Point", and use the brush to select a position. To remove it from the 3D world, select "Remove Point".

Open Panel

The button to open the panel in the session interface.

To open the panel for testing purposes, you can select "Open Panel" to open the panel in the session interface. You can also open the panel in the web browser by selecting "Open in Web Browser".

Content

Configuring and instantiating template panels

Template:Editor ribbon When you select a template panel, the right panel will be filled with the information pertaining to the template panel. A number of properties can be configured. Most properties are the same as for single panels. The important differences are listed here.

The right panel for template panels in the editor.

Name for template panel

The field for the "name".

The name of the panel. The name of an instance of a panel is composed of the name of the template panel, and the name of the item the template is applied on.

Stakeholder for template panel

The additional fields for the "stakeholder".

The stakeholder who has access to this panel. Rather than set a specific stakeholder, you can specify the type of relation the stakeholder should have with the item in question. For example, the "Use Owner" checkbox indicates that whoever owns an item at the time that the template panel is applied, is set to be the stakeholder with access to the panel.

The "Relational Filter" will make instances of panels appear only if the configured stakeholder has the indicated relation with the item the template panel is applied on. For example, if the filter is set to "Net Owner", and a stakeholder is set for the panel, there will only be instances of this template panel generated for those items of which the stakeholder is the net owner.

Template

The options for applying the template panel.

"Apply Template on" indicates what kind of item the template should be applied to. "With Attribute" allows a filtering on what items to apply the template panel to. If set, it will only be the items of the specified kind, with this specified attribute set to a non-zero value, for which panels will be created.

Not viewable

Note that there are no options to directly test what this panel will look like. This is because the template panel is merely a definition of how the actual instances should be structured, but which by itself is not an actual instance.

Applying

The "Apply Template" button will cause the actual instances of the panels to appear.

When the template panel is configured correctly, it can be used to create the actual panel instances which appear in the project. Select "Apply Template" to create the panel instances. You will be prompted with a message indicating how many panels will be created, which you can verify before creating the panel instances.

Editing panel instances

After applying a template panel, so that one or more panel instances are created based on the template panel, it is possible to edit them as though they were single panels. However, this practice is discouraged, because it is a common possibility that after applying the template, the template should be tweaked slightly to improve it and the instanced panels derived from it. After re-applying the template, any alterations made to specific instances of the panels are lost, as the instances are created anew. Instead, it is recommended to tag the items the panels are applied on using attributes, and including in the template panel itself some logic to handle the situations where that attribute is or isn't present.

Adding and editing answers

Adding/removing answers

How to add a template panel:

1. Select the panel you wish to add an answer to in the left panel.
2. Select "Add Answer".

How to remove an answer from a panel:

1. Select the answer you wish to remove.
2. Select "Remove".

Configuring answers

When you select an answer, the right panel will be filled with information pertaining to the answer. A few properties can be configured.

The right panel for answers of panels in the editor.

Name for answer

The field for the "name".

The name of the answer. The name is displayed to the end-user when the panels is opened, and is the text of the answer the end-user may choose. The name can be changed by changing the value in the name field.

Events

The events fired when the answer is selected.

The events fired when this answer is selected. The events are decided into server events and client events. Server events will also trigger changes in the state of the session. Client events will only affect the visualization of the end-user who selected the answer.

For the exact steps for adding, removing, and changing events, please see Editing Events.

Answers as part of template panels

Answers can also be added to template panels. When the template panel is applied on an item type, each event of each answer attached to the template panel is checked on whether they feature that same item type as parameters. If so, for each instance of the panel those parameters are changed to the exact item that panel instance is created for. For example, if an answer is defined with the NEIGHBORHOOD_SET_ATTRIBUTE event, and the template panel is applied on neighborhoods, each instance will have their answer with the NEIGHBORHOOD_SET_ATTRIBUTE event effect the specific neighborhood the instance is created for.
