Make 5 Stunning Pro GUI Applications in C++

Learn how a server stores content and serves it to clients, and how a proxy server acts as a gateway with caching to speed requests.

Explore the differences between TCP and UDP, comparing reliable, connection-oriented delivery with guaranteed in-sequence packets to faster, unreliable delivery used in video conferencing, live streaming, and online games.

Explain processes versus threads: a process runs independently with isolated memory, while a thread is a lightweight unit inside a process enabling multithreading, shared memory, and context switching.

Install Python from python.org, set up an IDE like PyCharm, and create a Python project with a first video tutorial.py to start coding.

Configure music player widgets, showing current and total time, with play, stop, and pause controls in a horizontal layout, plus hover styling, rewind button, and volume slider (0–100, default 50).

Implement a music player with play, stop, and pause using QMediaPlayer and audio output for local file URLs from a playlist, managing current index and pause state.

Develop a music player feature by selecting a song from a list widget, updating the current index with change track, and driving play and pause with the play button.

We set up a GUI window for the screen recorder app by creating an application and widget, setting the title and size, and displaying the window with an executable method.

Build a screen recorder UI in C++ using Qt box layouts, center the title label, and style the record button. Organize widgets in a vertical layout for upcoming recording functionality.

Learn to implement a screen recorder: press record to start, choose a save location via a file dialog, then switch to stop recording; integrates a queue process and signal-slot connections.

download ffmpeg from ffmpeg.org/download.html, choose the build for the operating system, extract it to access ffmpeg executable in the bin folder, and prepare for screen capture with audio via DirectShow.

Explain starting the screen recorder: switch the record button to stop, build and run an ffmpeg command for screen capture and audio with a chosen microphone, then minimize the window.

Configure microphone input in system settings, start and stop screen recording, save output as mp4, and update the recording UI with button text, font size, and colors.

Build a pdf to audio app interface by creating a gui window, setting main window title to pdf to audio app, resizing to 400 by 300, and launching the app.

Build a pdf to audio book converter GUI in Qt using a vertical box layout, adding a title label, choose pdf button, file name label, convert button, and status label.

Click the choose button to open a file dialog (signal/slot) to select a PDF, store its path, update the status and file name labels, and show the convert button.

Add convert button logic to read the file path from the file name label, update status text, and plan a pdf-to-audio conversion via a server.

Implement a pdf to audio conversion feature in a pro gui app by uploading the pdf to a local server via http multipart post and updating the status.

Install Python from python.org, then set up the PyCharm IDE for easier coding. Create a Python project and file to start writing code.

Set up a Python server to convert PDFs into audio books with a convert function on port 5000. Install modules and run the server to support a C++ client request.

Create the application and a widget, set the window title to video converter formats app, and resize to 400 by 300. Show window and call executable method to display it.

Set up a vertical box layout for the video extension converter app, add title and instruction labels, center text, and style with style sheets in Qt C++.

Add a select button to open file dialog. Display video path in a label, and provide a format drop-down with a convert button for mp4, mkv, mov, or wav.

Wire up the select button to open a file dialog, capture the video file path, and reveal the file name label, format dropdown, and convert button.

download the ffmpeg source code from ffmpeg.org/download.html, then extract it to a chosen location; choose the appropriate Linux, Windows, or Mac build, and await the next video for setup steps.

Learn to build a video extension converter app in C++ using ffmpeg, handle file paths, user format selection, and status updates while converting videos with qprocess.

Explore core C++ concepts from iostream basics to object-oriented programming, covering variables, data types, arrays, strings, operators, control flow, functions, prototypes, recursion, and inheritance.
