QR Generator (Windows)

Simple desktop app: enter content (number / URL / phone / WhatsApp / image / text) → generate the QR → save it as PNG.

Features

• QR preview.
• Supports QR codes for numbers, URLs, phone numbers, WhatsApp, images, and plain text (select the type in the app).
  • Note: to “show an image” when scanning, the QR must contain a URL. Prefer a public http/https image URL. file://... works only on the same PC.
• Option to add a footer image (optional) or choose an image at generation time.
• Installer with Spanish / English language selection.

Requirements

• Windows
• Python 3.11+ (this workspace already uses a venv in .venv/)

Run in development mode

1. Install dependencies:

   ./.venv/Scripts/python.exe -m pip install -r requirements.txt

2. Run the app:

   ./.venv/Scripts/python.exe qrgen.py

App logo

Footer image (in the app)

In the window you will see:

• Add footer image: enables/disables the footer image (not mandatory).
• Choose…: select any image (PNG/JPG/JPEG/BMP/GIF) as footer.
• Default: uses the image included with the project (Logo pausa.jpeg) if present.
• Remove: generates the QR without a footer image (but keeps the option enabled).

Tip: if you want to change the default logo for everyone, replace the file Logo pausa.jpeg with another image using the exact same name, then rebuild.

App language (Spanish / English)

• The installer lets you choose the language.
• The app uses that language on first launch.
• You can later change it from the Language / Idioma menu inside the app.

Generate an EXE

Run:

powershell -ExecutionPolicy Bypass -File .\build.ps1 -Mode onedir

Output:

dist\QR-Generador\QR-Generador.exe

Alternative (single file)

This usually takes longer to start:

powershell -ExecutionPolicy Bypass -File .\build.ps1 -Mode onefile

Output:

dist\QR-Generador.exe

Build everything (EXE + installer) with one command

If you made changes and want to generate everything at once:

powershell -ExecutionPolicy Bypass -File .\build-all.ps1

This builds:

• EXE (PyInstaller, folder mode) → dist\QR-Generador\QR-Generador.exe
• Installer (Inno Setup) → installer\Output\QR-Generador-Setup.exe

Useful options

• EXE only:

  powershell -ExecutionPolicy Bypass -File .\build-all.ps1 -AppOnly -Mode onedir

• Installer only (if the EXE already exists in dist):

  powershell -ExecutionPolicy Bypass -File .\build-all.ps1 -InstallerOnly

Create installer (optional)

If you want a classic “Next, Next, Finish” installer, the simplest option is Inno Setup.

1. Generate the build (folder mode) if it doesn’t exist yet:

   powershell -ExecutionPolicy Bypass -File .\build.ps1 -Mode onedir

2. Install Inno Setup (once, on the PC where you will build the installer).

3. Option A (automatic):

   powershell -ExecutionPolicy Bypass -File .\installer\build-installer.ps1

4. Option B (manual): open installer\qrgen.iss with Inno Setup and click Compile.

Output:

installer\Output\QR-Generador-Setup.exe

Installer language (Spanish / English)

The installer shows a language selector at startup. To change or adjust texts, edit installer\qrgen.iss (section [CustomMessages]).

Use on another PC

Copy the installer file and run it:

installer\Output\QR-Generador-Setup.exe

This creates the program folder and desktop shortcut, and the app is ready to use.
