[docs]class SimulatorFragmentRenderingRules(object): """ This class gathers the rendering rules for simulator_fragment template. TVB > 2.0 brings a change of UI inside the simulator configuration page. Instead of a pre-loaded huge form with all the configurations, we want to have a wizzard-like page. Thus, the configurations are grouped into fragments and each fragment is rendered as a separate form. Each form provides the user with Next/Previous buttons, and some of them bring some extras: - model form provides the buttons: setup region model parameters/setup surface model parameters; - last fragment provides extra Launch/Setup PSE buttons, and a Branch button when it's the case. There are several cases that should be taken into consideration for the UX: - for a normal configuration, the user would just select the proper configurations and click Next to go to the next form. When the Next button is clicked, the current form is made read-only. If the user need to make changes to a previous form that is already read-only, he might use the Previous buttons to get there, make the change, and come back clicking Next again. - from the history list, the user could choose to inspect an existing simulator configuration, by clicking on it. This will load the full configuration as read-only forms, without any buttons. - from the history list, the user also has the option to copy an existing simulator configuration A and edit it, or start a new simulation B using the results from A as initial conditions. This results, in a semi-read-only load of simulator configuration A, because the user will have the options: - to use the Previous buttons in order to edit configuration A and the Launch/Setup PSE buttons to start a new simulation. - to use the Branch button in order to start a new simulation B that will use results from A as initial conditions. So, we need a series of rendering rules, to know when to display/hide each button, and also make fields read-only.
