===Design canvas===
The design canvas is in the center of the control. This is the space where activities can be placed and arranged, typically with Drag&Drop from the Toolbox.
===Property window===
The property window consumes the right area of the control and is there to configure a single workflow activity. A typical configuration consists of supplying parameters with expressions or variables.
All parameters are directed, which means they are either
* In
* Out
* Both
There is no design restriction that comes with that, it is more a supporting feature telling something about the argument: an inbound parameter will never write to a variable supplied and an outbound parameter will never read a value supplied to it.
===Working with the designer===
* The FlowChart executes its nested activities in the order you link them with connecting lines
After placing a new activity, use the [[#Property window|Property window]] to configure its arguments. Misconfiguration of an argument typically leads to a red exclamation mark on the activity, where the tooltip text displays the details of the error. {{Hint|Some activities expose special designers, that allow you to edit selected arguments directly in the canvas. However, this is just a different and limited view, the property window will always show all available arguments}} ==Other functionality=Variables===Variables are meant to pass values between activities and are therefore very important for the logic of a workflow. So if you want to i.e. pass a string from activity A to activity B, you need to* create a variable* assign it to an out string parameter of activity A* assign it to the in string parameter of activity B Variables can be created in the variables editor which is located at the bottom area of the design canvas. Once created, a variable can be referenced by its name in the activities. {{Attention|Unlike function or method names, variable names are case-sensitive}}
