Center-Windows

Center-Windows is a lightweight background utility for Windows that automatically centers new windows on the screen. This feature is commonly found in Linux environments but is often unavailable or requires paid software on Windows. Center-Windows aims to solve this problem by providing an easy-to-use, free alternative.

Features

• Automatic Window Centering: Centers newly opened windows on the screen.
• System Tray Icon: Includes a system tray icon for easy control and status indication.

Installation

Option 1: Installer

You can download the precompiled installer from the Releases page.

1. Download Installer:

   • Navigate to the Releases page.
   • Download the latest Center-Windows-Setup.exe installer.

2. Install the Application:

   • Double-click on the installer file (Center-Windows-Setup.exe).
   • Follow the on-screen instructions to complete the installation.

3. Run the Application:

   • Once installed, you can run the application from the Start menu or desktop shortcut.

Option 2: Manual Compilation (Advanced)

1. Clone the Repository:

  git clone https://github.com/Basiiii/Center-Windows.git
  cd Center-Windows

2. Create a Virtual Environment (optional but recommended):

  python -m venv venv

3. Activate the Virtual Environment:

  venv\Scripts\activate

4. Install Dependencies:

pip install -r requirements.txt

5. Run the Application:

• To run in your terminal:

  python Center-Windows.py

• To compile and create an executable (allows running in the background without a terminal):

  python setup.py py2exe

  This will create an executable in the dist directory.

Usage

Once the application is running, it will automatically monitor for new windows and center them on the screen. The application runs silently in the background and can be controlled via the system tray icon.

System Tray Icon

• Hover Text: Displays "Center-Windows" when you hover over the icon.
• Quit: Right-click the system tray icon and select "Quit" to exit the application.

How It Works

Main Components

1. Window Monitoring: Continuously checks for new windows and centers them if they are not in the ignore list.
2. System Tray Icon: Provides an interface for users to interact with the application.

• get_window_title_from_hwnd(hwnd): Retrieves the title of the window associated with a given window handle.
• center_window(window): Centers a given window on the screen.
• on_quit_callback(sysTrayIcon): Stops the application and exits the monitoring loop.
