tkinter - Make input table with initial entries and save changes with tikinter in python -


i trying make input table in python using tkinter. input table has initial values can changed. when alle inputs have been edited, want save changes. use tinydb database store input values.

can show easy example on how that?

i see got lot of critical responses not showing initial code. think found solution when typing simple example, seems work ok. have make object oriented, though.

from tkinter import * tinydb import tinydb, query  # name on database stored parameter values (confined , free parameters)  param_db_name = 'db5.json'   db2 = tinydb(param_db_name)    # field name , values free parameters in model1:  model_name = 'model1'   felt = query()   fields = (db2.search(felt.model_name == model_name)[0]['free_par']).keys()   fields_val = (db2.search(felt.model_name == model_name)[0]['free_par']).values()   #print('fields_val: ',fields_val)    def save_params(entries, fields):      res_dict = {}    field in fields:       res_dict[field] = float(entries[field].get())    print('res dict:', res_dict)    felt = query()    db2.update({'free_par': res_dict}, felt.model_name == model_name)   def makeform(root, fields,ff):    entries = {}    = 0    field in fields:       row = frame(root)       lab = label(row, width=32, text=field+": ", anchor='w')       ent = entry(row)       ent.insert(0, [ff[i]])       row.pack(side=top, fill=x, padx=5, pady=5)       lab.pack(side=left)       ent.pack(side=right, expand=yes, fill=x)       entries[field] = ent       i=i+1    return entries  if __name__ == '__main__':    root = tk()    root.wm_title("model parameters")    ents = makeform(root, fields, list(fields_val))    b1 = button(root, text='lagre',command=lambda: save_params(ents,fields))    b1.pack(side=left, padx=5, pady=5)    b2 = button(root, text='avslutt', command=root.quit)    b2.pack(side=right, padx=5, pady=5)    root.mainloop()

the db2 database consists of 2 entries:

[{'model_name': 'model1','con_par': {'cpar1': 1, 'cpar2': 2, 'cpar3': 3.0},'free_par': {'fpar1': 0.589, 'fpar2': 1.44, 'fpar3': 3.0, 'fpar4': 2.427}},  {'model_name': 'model2','con_par': {'cpar1': 11, 'cpar2': 12, 'cpar3': 13.0},'free_par': {'fpar1': 10.589,'fpar2': 11.44,'fpar3': 13.0,'fpar4': 12.427}}]

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...
