Configuration

{
"should_auto_update": false, # (optional), default to false.
# If true, the widget will perform live calculation
# If false, the user have to click reload to update the value
"should_auto_update_when_empty": true, # (optional), default to true.
# If true, the widget will perform live calculation when the data is empty
# If false, the results will not be calculated on default

SMILES Structure
This widget uses Smiles Drawer to draw the chemical structure from SMILES.
Readonly view:
Click the 'Generate SMILES' button to create molecular weight based on the chemical name.

Import value:
SMILES string.
Molecular Formula
This widget can:
Generate molecular formula from the name
Generate molecular weight
Generate SMILES (Simplified molecular-input line-entry system)
Generate molecular structure
This widget requires the creation of these columns before it can be used. By default, these columns are created automatically in the chemical table.
molecular_weight
SMILES
molecular_structure
Some function of chemcalc is used for this widget.
