I'm not sure if this is the right place to ask a newbie question, if there is a better place please let me know. I have a form with a number of checkboxes and I want to be able to set them all to checked when a button is clicked. I have some code as follows:

button := testForm.AddButton("Select all", func() {
    for i:=0; i<testForm.GetFormItemCount(); i++ {
      item := testForm.GetFormItem(i)
      //item.checked = true
      fmt.Printf("1. Item Type    = %T\n", item)
      fmt.Printf("2. Item Type    = %T\n", &item)
    }
}

I would like to be able to programmatically check each checkbox item. I have tried using item.SetChecked() but I am told:

item.SetChecked undefined (type tview.FormItem has no field or method SetChecked)

When I print out the item type of item I get *tview.CheckBox and when I print the type of &item I get *tview.FormItem and when I print the value (using %v) I get what appears to be a struct with 12 fields which is where I think the value I want to set resides.

Any help clearing this up would be appreciated, I have searched online and perused the demo code trying to find examples of how to work with checkboxes without much luck.

Regards,

Daryl

Thanks for your reply, I appreciate the explanation and the example code, it really helped me to understand the Go language better and helped me get that code working.
