Wrong selected Item with surselection

*curselection

So I am very new to Ruby and Tk and I have a Problem, which solution I didn't find after hours of research:

I have a directory which contains many projects.
With the following code I insert the names of the existing projects into a Listbox:

$projects = Dir.entries("#{Dir.pwd}/projects")[2..-1] 
$projects.each {|f| $list.insert 'end', f} 
 

I created a searchbar with a button which allows to find a specific entry:

def searchprojects
    searchedprojects = []
    $list.clear()
    if $spec_ent.to_s.empty?
       $projects.each {|f| $list.insert 'end', f}
    else 
       $projects.each {|i|
           i = i.to_s
 

searchedprojects.insert(searchedprojects.length(), i) if i.downcase.include? $spec_ent.to_s.downcase}
searchedprojects.each {|f| $list.insert 'end', f}
end
end



And with the following code I chose the selected project (which shall be filtered before):

def show_project
  # updates the status of the chosen project 
  idx           = $list.curselection[0]
  $proj_name    = $projects[idx]
  $status.value = "Project chosen: #{$proj_name}"
end
 

My Problem: After I filtered the Listbox with my searchbar, and I chose a project in the Listbox, I get the wrong drectory(name), because of the index. For instance, when i filter the Listbox, it contains only 3 entries, and I chose the third, it will give me the third entry of the unfiltered Listbox.

Thanks for helping.

Solution:

def show_project
  # updates the status of the chosen project 
  chosenList    = $list.curselection()
  chosenItem    = chosenList[0]
  $proj_name    = $list.get(chosenItem)
  $status.value = "Project chosen: #{$proj_name}"
end
