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:

1. Generate molecular formula from the name

2. Generate molecular weight

3. Generate SMILES (Simplified molecular-input line-entry system)

4. 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.
