Add bond custom query field

[AlexanderSavelyev]

Background
There is no way to make a SMARTS query for bonds

Solution
Add Text field to the Ketcher Bond Properties

(checkbox) "Custom query"
(input textfield)

• By default, checkbox=False, text field is empty and disabled

• if checkbox is true then text field is enabled, but all other controls in bond properties are disabled and should be empty

• if checkbox pressed to false again, the properties should return to the initial states

• after press on checkbox=true then all the current properties should be copied into the input field with ";" as a separator

  • following SMARTS to be used
  • single bond: -
  • double bond: =
  • triple bond: #
  • aromatic bond: :
  • any bond: ~
  • single up: /
  • single down: \
  • topology ring: @
  • in all other cases make empty

• Examples

  • e.g. if Bond Type= "Single" , Topology = "Either"
    then customQuery = -

  • Bond Type= "Double" , Topology = "Ring"
    then customQuery = =;@

• Only one validation: input field should not be empty

• If custom query is not empty UI Ketcher should display content of the custom query on the bond. Bond should be displayed on canvas as any bond

• after pressing apply with (customQuery not empty and checkbox=true) and press edit the bond again, press checkbox=false then the bond properties should be set to default: type=single, topology=either, center=unmarked

• In KET format customQuery should be saved into the bond object without other properties

• right click menu should be available without any changes. If customQuery is defined on a bond and the type is changed by right click menu (e.g. select Single bond) - the customQuery should be removed from the bond
