python - searching in treeview and highlight/select the row that contains the item that is searched -


i making simple gui patient's list patient's name , date of visiting, using tkinter , treeview, have entry user should type name of patient , idea if name of patient located in list, row (or rows) contain patient's name highlighted(selected). or other option can in listbox patients, display entries patient's name search for.

i have not used treeview before , not find data functions , examples, struggling selection/highlight part, ideas helpful @ point....

my code far is:

import tkinter tkinter import ttk  class mainpage:      def __init__(self,master):          self.master = master         self.frame = tkinter.frame(self.master)         self.master.columnconfigure(0, weight=1)         self.master.columnconfigure(1, weight=3)         self.master.columnconfigure(2, weight=1)         self.master.columnconfigure(3, weight=1)         self.master.columnconfigure(4, weight=1)          self.searchfield = tkinter.frame(self.master)         self.searchfield.grid(row=1, column=0, columnspan=4)          self.search_var = tkinter.stringvar()         self.search_var.trace("w", lambda name, index, mode: self.selected)         self.entry = tkinter.entry(self.searchfield,                       textvariable=self.search_var, width=45)         self.entry.grid(row=0, column=0, padx=10, pady=3)         self.searchbtn = tkinter.button(self.searchfield, text='search',                           command=self.selected)         self.searchbtn.grid(row=0, column=1)         self.treeframe = tkinter.listbox(self.searchfield, width=45, height=45)         self.treeframe.grid(row=1, column=0, padx=10, pady=3)           self.tree = ttk.treeview( self.treeframe, columns=('name', 'date'))         self.tree.heading('#0', text='id')         self.tree.heading('#1', text='name')         self.tree.heading('#2', text='date')         self.tree.column('#1', stretch=tkinter.yes)         self.tree.column('#2', stretch=tkinter.yes)         self.tree.column('#0', stretch=tkinter.yes)         self.tree.grid(row=4, columnspan=4, sticky='nsew')         self.treeview = self.tree          self.i = 1         self.patient_list = [{"name": "jane", "date": "05.09.2017"},                              {"name": "david", "date": "04.09.2017"},                              {"name": "patrick", "date": "03.09.2017"}]         p in self.patient_list:             self.tree.insert('', 'end', text="id_"+str(self.i), values=                              (p["name"], p["date"]))             self.i = self.i + 1          self.search_item = self.entry.get()         p in self.patient_list:             if p["name"] == self.search_item:                 self.selected(self.search_item)       def selected(self):         currentitem = self.tree.focus()         print(self.tree.item(currentitem)['values'])    root=tkinter.tk()  d=mainpage(root)  root.mainloop()

thanks in advance!

please see explained snippet below:

from tkinter import * tkinter import ttk  class app:     def __init__(self, root):         self.root = root         self.tree = ttk.treeview(self.root) #create tree         self.sv = stringvar() #create stringvar entry widget         self.sv.trace("w", self.command) #callback if stringvar updated         self.entry = entry(self.root, textvariable=self.sv) #create entry         self.names = ["jane", "janet", "james", "jamie"] #these test inputs tree         self.ids = [] #creates list store ids of each entry in tree         in range(len(self.names)):             #creates entry in tree each element of list             #then stores id of tree in self.ids list             self.ids.append(self.tree.insert("", "end", text=self.names[i]))         self.tree.pack()         self.entry.pack()     def command(self, *args):         self.selections = [] #list of ids of matching tree entries         in range(len(self.names)):             #the below if check checks if value of entry matches first characters of each element             #in names list length of value of entry widget             if self.entry.get() != "" , self.entry.get() == self.names[i][:len(self.entry.get())]:                 self.selections.append(self.ids[i]) #if matches appends id selections list         self.tree.selection_set(self.selections) #we select every id in list  root = tk() app(root) root.mainloop()

so this, every time entry widget updated, cycle through list of names , check if value of entry widget matches value of element in names list length of value of entry widget (eg, if enter 5 character long string check against first 5 characters of element).

if match append id of tree entry list.

after names have been checked pass list of matching ids self.tree.selection_set() highlights of matching tree entries.

Add a dynamic header in angular 2 http provider -

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom...
