Flow Tree and Global Flow Tree

## Flow Tree and Global Flow Tree
Any vision inspection project in VG3 is composed of flows. The flow arranges the inspection steps through functions, so as to adapt to different inspection scenarios. VG3 supports the creation of multiple flows, and each flow does not interfere with each other. At the same time, cross-flow data interaction and execution logic can also be designed through global flows and global variables.

## General Understanding of Project, Recipe, Flow, and Module
VG3 takes Project as the highest naming. Multiple recipes can be created in a project. There are two types of recipes, ***one is General Recipe, and the other is Global Recipe***. There can be only one global recipe, which is composed of multiple global flows. There can be multiple general recipes, and each general recipe can create multiple flows.

Please see the structure diagram below for better understanding.

#### ①: Flow Settings:
Includes flow name modification, flow search, flow prohibition running setting, flow prohibition display, flow execution mode, flow trigger ID, flow trigger interval time, whether to print logs (if yes is selected, the log print will be saved to the hard disk file, please check the latest file starting with info under VisionGroup2/logFile folder information)

>d **Deprecated**
>
> Whether it is a sub-flow, if there is a sub-flow, sub-flow input and output settings

#### ②: Recipe Name
#### ③: Flow Online Editing
For details, please refer to the [Online Editing](#h3-Online-Editing) introduction below
#### ④: Function Drag Enable
After locking, dragging inside the function list will be prohibited
#### ⑤: New Folder
Create a new folder and place some associated flows in different groups under folders to make the project easier to understand and maintain.
#### ⑥: Add Flow
Add a new flow under the current recipe
#### ⑦: Add Sub-flow
>d **Deprecated**
>
> Add sub-flow function, clicking it to create a flow is consistent with the effect of a normal normal flow.

### Global Flow

### Online Editing
Select a flow and click this icon to display the function tree editing interface of the currently selected flow in full screen.

#### ①: Replace Flow
Replace the modification of this flow to the current project. Click this button to save the modified parameters and replace them in real time. **Note that the flow compilation must be successful before the replace flow operation can be successful.**
#### ②: Save Project
Replace the modification of this flow to the current project, and save the modification of the entire project at the same time.
#### ③: Compile Flow
Check the port connection, data structure, function logic, etc. in the flow. If there is a problem, the compilation will fail, and all error messages will be displayed in the software prompt information area.
#### ④: Detection Settings
You can set some types of functions to be skipped during detection or continuous detection.

Flow supports import and export, reset (all functions under the flow will be cleared after reset), and other operations can be understood literally.
