Select Unselect logic in Salesforce - salesforce

I have a requirement, where there is a checkbox on UI when I select it the first time it gets selected when I click it again it is deselected.
So in logic, I am adding the selected parameter to a set, and if it is already present I remove it for deselecting the parameter.
But this approach is not working when I have to count how many I have total, it gives incorrect values.
I have to implement select multiple and deselect multiple in a web page. Can anyone help me with this

Do you have a wrapper? Have a select all/deselect all command link, that command link will call an action which will select/deselect all of the records, then just rerender the table..

I am new to react and need your help.
I have a dropdown and on selecting a value I am checking if selected value is not meeting a condition I need to prompt a dialog box to user if he wants to continue to go with the selection,if he selects yes then selected value to be saved in database.
On select and on selecting yes are two callback functions. My query is how to set the state for current selected value during OnSelect callback so that I can make it available within OnSelectYes also.

Material-Table replace checkboxes with radio buttons

I'm using material-table to show some data, now I want to select one row at the time to pass the row's data to another component, so being able to select multiple rows at the time isn't what I'm looking for and the main suggestion is to go for a radio button. So is there a way to replace the checkbox on the table with radio buttons or make the selection option to only allow one row to be selected at the time?
According to documentation your hands are tied. But, this might work:
Add selectedRow key to the component which uses MaterialTable
Create some method or function e.g. handleSelection and pass it to onSelectionChange prop. Argument to this func is an array which handleSelection returns
When user select some row, set selectedRow to that row object
If user click on "slelect all" checkbox (top left) - show notification that action is not supported. If there is no way to unselect all checkboxes programatically - unmount and than mount MaterialTable (to reset checkboxes)
If one row is already selected, than another one get selected (which makes two selected rows) - repeat step "4"
I know this is a bit complicated, but it's a best I could think of at the moment
n.b. Another thing you can do (to force users to select only one row) is to hide table on multiple selection and show message about what they can do. Message could be closable. When message get closed fresh table could appear (mount aggain).
Update
Just have found another option that might work for you. Take a look at this page at the "Simple Action Example". There you have buttons instead of checkboxes. I am starting to think that:
options={{
selection: true
}}
is not the right option for you.

How to access click event of option in React dual list box?

I am using react-dual-listbox. Here I am able to select the columns and deselect and use the selected values. But, I want to access the selected option in selected items on click of that particular item.

Deselecting a ttk::checkbutton

I have defined multiple ttk::checkbutton in a table. There requires a single Master checkbutton which will select or deselect all other checkbuttons at once. We can also select single checkbutton.
Now the problem is, I can select the child checkbuttons But I can not deselect them through code. I know I can deselect them all with a variable but I dont want to do that.Because all checkbuttons will then be linked. what to do.
Is Linking all checkbuttons with with different variables and then reseting them is the only option ?
Select code which works fine:
$childCheck state selected
the deselect code I have tried but failed:
$childCheck state deselected
Just got the answer. :)
Instead of deselected use !selected in state.
$childCheck state !selected
