TCP/IP Client server persistent connections

-

So just last week I was moved to another project where I'm gonna be working on a client server program.
So we are going to be using TCP/IP for communication. And its exciting since its been over two years since I last dabbled in networking. Life is looking exciting.
Anyway so the problem was everywhere I looked, I could find only simple networking examples. So I dug in and put together some code to keep a connection alive for back and forth connection. What I did was basically keep the connection open for next request rather than closing it and reopening it.
This enabled me to have a continuous chat like communication between client and server.
Then I spent some time refactoring the code to make it streamlined.
But I still have to add error handling to it. I'll share it here when I have it ready. It was fun!!!

QCalendarWidget CSS Stylesheeting

-
Recently I had to implement a calendar for a TouchScreen application. I resorted to css to modify the calendar widget's appearance so that it would be more accessible. Following is the code that enabled me to get a proper calendar. calendar->setStyleSheet("QMenu { font-size:20px; width: 300px; left: 20px; }"     "QToolButton {icon-size: 48px, 48px; font: 20px; height: 70px; width: 100px; }"     "QAbstractItemView {selection-background-color: rgb(255, 174, 0);}"     "QToolButton::menu-indicator{ width: 50px;}"     "QToolButton::menu-indicator:pressed,"     "QToolButton::menu-indicator:open{ top:10px; left: 10px;}"     "QTableView { font: 30px; }"     "QSpinBox { width: 100px; font: 20px;}"     "QSpinBox::up-button { width:40px;}"     "QSpinBox::down-button { width:40px;}");

Selecting new phone plan

-
I use a Reliance Jio SIM as my one and only cellphone number. I used to have another, but I found little use for that. So I discontinued that other SIM card. It was a Vodafone SIM and I had bought it thinking I would be using it when I visit my hometown. Turns out it's not usable there. So adios. Coming back to Jio, it was working so far so good for a while. And it was quite cheap. Then they increased the fares about 4-5 months ago. And it was costing ~Rs 7 per day. This was for unlimited Jio-Jio calling, ~300minutes free to other telcos, and 1.5GB daily cellular data. Now I got home internet, so I thought to cut costs on this. The current plan goes for INR555 for 84 days. This includes 1.4GB 4G cellular data per day, 300 min calling to other telcos, and jio-jio free. That's Rs 6.6 per day. Now I'm not even using 30minutes calling per day. And due to home internet my cellular usage has gone down. So I decided to go for some other cheaper plan. This one is INR1299 for 336 da...
