A new command can be a Python script, graph, or C++ plugin. Furthermore, it is possible to embed a command to RealFlow or keep an external file and create a link to it – a so-called reference. Click on the “Add” button and choose which type of command you want to create:
- A new dialogue appears – most of the input fields are self-explaining.
- Fill in the fields, create a shortcut, and choose an icon.
- Your changes will be saved to “RealFlowCommands.xml” file specified under → "Preferences".
C++ Plugins can also be added, but they are installed by throwing them to one of the folders under “plugins” of RealFlow's application directory.
Input Parameters
When a graph with “GraphInterface” nodes is executed you will see a user interface with initial values. Please take a look at the graph below:
Each of the three “GraphInterface” nodes has an initial value that is displayed in a small UI when you execute the graph with the triangle button.
The buttons of the “Input Parameters” provide direct access to these interface nodes and their values:
- “Edit Parameters [3]” let's you change the names of the three “GraphInterface” nodes' parameters.
- “Edit default values” is used to change the start values of the parameters.
- “Edit next execution values” let's you define a second set of values when the graph is executed the next time.
The checkboxes define when the graph's UI is shown:
- “Never”. The UI will not be shown, but the default values are used for the command's execution
- “On first execution”. With this option, the UI will be shown only once during a session.
- “Always”. In this case, the UI will be shown when the command is executed.
