Download

You can download the latest pre-compiled binaries for Windows and Linux from the GitHub Releases page.

Window Repositioning

• Corner Positioning & Dragging: You can select a screen corner (Top-Left, Top-Right, Bottom-Left, Bottom-Right) in Settings -> Display, or drag the widget window directly on screen.
• Linux (Wayland & Snap): On Linux (including Wayland sessions and Snap packages), you can reposition the widget to any custom location by holding Super + Left Click Drag. WeatherWidget automatically detects the new coordinates and persists them for future app launches.

Compilation

Windows

    $env:PATH = "C:\msys64\ucrt64\bin;" + $env:PATH; $env:CGO_ENABLED = "1"; gcc --version | Select-Object -First 1

    go build -ldflags="-H windowsgui -s -w" -o weatherwidget.exe ./cmd/weatherwidget/
    .\weatherwidget.exe

Windows MSI Package

 .\installer\build-msi.ps1 -Version "1.2.0" -SkipSign

Linux

1. Install dependencies:

   sudo apt-get update && sudo apt-get install -y libgl1-mesa-dev xorg-dev

2. Build:

   make build

3. Build Snap Package:

   ./scripts/build-snap.sh
   # or
   make build-snap

Note: The first build may take several minutes as it compiles graphical dependencies (CGO). My updated Makefile includes the -v flag so you can monitor progress.

Troubleshooting

"Nothing happens" when clicking Settings or Weather Panel

If the app appears in your system tray (or is running in the background) but clicking Settings or Show Weather does nothing, it usually means the application failed to create the UI window.

You can verify this by running the application from the command line with the -debug flag to enable logging to a file:

.\weatherwidget.exe -debug

Then, check the log file at:

type $env:APPDATA\WeatherWidget\debug.log

If you see the following error: Cause: APIUnavailable: WGL: The driver does not appear to support OpenGL

The Fix: This happens on "clean" Windows installations (using the Microsoft Basic Display Adapter) or in Virtual Machines because the system lacks proper graphics drivers to support the required OpenGL 2.0+ context.

There are two ways to fix this:

1. Install Graphics Drivers: Install the proper Intel/AMD/NVIDIA graphics drivers for your system.

2. Use Mesa3D Software Renderer (Portable Fix): If installing drivers is not an option:

   • Download a pre-compiled Mesa3D for Windows package (e.g., from fdossena.com).
   • Extract the 64-bit opengl32.dll file.
   • Place that opengl32.dll file directly in the same folder as your weatherwidget.exe.

   Windows will automatically use this DLL to translate OpenGL hardware calls into software rendering, allowing the app to work flawlessly on any PC regardless of graphics drivers.

Note: A -software flag is also available (.\weatherwidget.exe -software) which instructs the Fyne framework to prefer software rendering, but this still requires basic OpenGL driver availability at the OS level.

  • Cancel Button: Added full localized translations (settings.cancel) across all 12 languages for both GTK and Fyne settings dialogs.
  • Live Taskbar & System Tray Menu Translation: Both GTK AppIndicator tray menu and Fyne desktop system tray now dynamically re-render all action items ("Show Widget", "Hide Widget", "Settings", "Quit") whenever the language is switched, keeping the taskbar menu perfectly in sync with the active UI locale.

v1.1.0 — 2026-08-19

• Font Size controls (GTK Linux) — New Font Size section in the Widget tab lets you independently adjust the text size for three areas of the widget:
  • City & Time — controls city name and clock (range 8–48 px)
  • Temperature & Icon — controls temperature value and weather icon size (range 10–72 px)
  • Weather Conditions — controls description, humidity, wind, and all info rows below temperature (range 6–36 px)
• Live font-size preview — Each row has ▼ / Npx / ▲ buttons that update the widget in real time as you click, with no need to hit Save first
• Icon scales with temperature — The weather icon resizes together with the Temperature & Icon font size so both grow and shrink in proportion
• Cancel reverts preview — Closing the settings dialog with Cancel restores all font sizes to what was last saved, discarding any unsaved live-preview changes
• Font sizes persisted — All three font size values are saved to config.json and restored on next launch; existing config files without these keys fall back to the original defaults.
• Full i18n coverage — Font size section title, subtitle, and all three row labels are fully translated across all 9 supported languages (English, German, Spanish, French, Italian, Dutch, Polish, Portuguese, Turkish)

v0.6.3 — 2025-06-26

• Added new "heavy rain" weather icon (heavy_rain.png) for heavy intensity rain conditions across all providers (OWM, WU, EWW)
• Fixed weather and time display staying frozen after PC wakes from sleep/hibernation — the widget now detects system resume and triggers an immediate refresh

v0.0.7 — 2025-07-03

• macOS: Rounded corners — Widget window now renders with 12pt rounded corners matching macOS design conventions
• macOS: Window transparency — Background transparency slider (25%/50%/75%/100%) now works on macOS using NSWindow.alphaValue with remapped values to keep content readable
• macOS: Auto-start at login — Added LaunchAgent support so the "Launch WeatherWidget when starts" setting works on macOS (creates ~/Library/LaunchAgents/com.weatherwidget.app.plist)
• macOS: Build script — Added scripts/build-darwin.sh for one-command universal .app + .dmg creation

v1.0.6 — 2026-07-31

• Humidity & wind display — Each city panel now shows humidity percentage and wind speed with compass direction (e.g. "💧 45% 💨 4.5 NW") below the weather description
• Live settings preview — Opacity, position, and temperature unit changes are applied to the widget in real-time as you adjust them in settings; reverts automatically if you close without saving
• Panel Display customization — New Widget tab in settings with checkboxes to toggle visibility of each panel element (City, Icon, Temperature, Description, Humidity & Wind, Time, Date) with a live 3-city preview
• Dynamic panel height — Widget window automatically resizes to fit only the visible elements when display fields are toggled
• Live About preview — The About tab now shows live weather data for 3 default cities with ticking clocks instead of a static screenshot
• Windows opacity fix — All transparency levels (25%/50%/75%/100%) now produce distinct visual results using combined LWA_COLORKEY + LWA_ALPHA
• Settings tab reorganization — Appearance tab renamed to Display; new Widget tab houses Panel Display and Temperature Unit with live preview
• Modernized Locations tab — City rows use icon buttons (move up/down/delete), bold city names, separators between entries, and coordinates grouped on a single row
