Countdown

Latest Release

Countdown provides a window on your desktop, counting for a specific date.

By default, it counts to 2025.6.7, the University entrance exam in China.

Features

• Customizable title, date and graphical effect.
• Auto refresh at 00:00 (current timezone).

Configuration

Click the '天' character on the bottom right to expand or fold settings panel.

Here you can set the date to count to and whether the window is Translucent (or, transparent) (Requires restart).

Other options can only be edited from consistent.ini. You can find it in the program directory after launching it for the very first time.

Config

Default config file as this:

[app]
Animation=true
TargetDate=2025-06-07
TargetString=距离高考还剩：
Timer=true
Translucent=true

[widget]
Stylesheet=".QWidget{ background-color: rgba(255,255,255,180); border-radius: 10px; } .QLabel{ color: black; } .QPushButton:checked{ color: green; }"

• [app] These are program behaviors.
  • Animation(bool): Whether window animation is enabled.
  • TargetDate(string): Target date, formatyyyy-mm-dd.
  • TargetString(string): The title of the countdown.
  • Timer(bool): Enable 12:00 update. On computers that definitely restart everyday (like a classroom computer), disabling this can save a little power. (has almost no difference on performance)
  • Translucent(bool): Whether window background is translucent.
• [widget] These are widget graphical effect.
  • Stylesheet(string): The stylesheet of the widget. See Style

Style

The default stylesheet in config:

[widget]
Stylesheet=".QWidget{ background-color: rgba(255,255,255,180); border-radius: 10px; } .QLabel{ color: black; } .QPushButton:checked{ color: green; }"

The format used is qss (q style sheet). Check Qt Online Help Document (EN), csdn(1) or csdn(2) for more details.

The base widget's name is centralwidget. Note that almost all ui element classes are derived from QWidget, so you should use .QWidget instead of QWidgetselector, as long as you don't want to apply it to everything. Check for names in ui file. For a more friendly interaction, try QtCreator or Designer application.

If you want to customize it without learning qss, give this to AI with your requirements:

Write a qss file which should be in a single line. 
The program is a Qt countdown widget, the background is QWidget centralwidget, Title: QLabel labelName, Content: QLabel label_Day, The main window has a configurable translucent background. 
Example: ".QWidget{ background-color: rgba(255,255,255,180); border-radius: 10px; } .QLabel{ color: black; } .QPushButton:checked{ color: green; }" 
My requirements are...

UI Behaviors

Countdown hovers 15 pixels from the top right corner of your primary display.

It automatically adapts to your scaling (Thanks to the powerful qt).

The geometry (position and size) is currently NOT adjustable.

You cannot move, resize, minimize/maximize or close the window.

The program creates a tray icon, which contains a "config" to your config file (Windows only) and "Quit".

Known issues

• (Ubuntu) Cannot hide its icon in the task bar.
• (Windows) "Config" tray menu not working.
