Our review

Provides design thinking and technical guidelines for creating polished QML widgets for the Quickshell desktop environment, specifically for the 'Obelisk' configuration.

Strengths

  • Structured design process with a clear aesthetic direction
  • Rigorous use of the Theme singleton for visual consistency
  • Existing reusable components (OText, OButton, OPanel, etc.)
  • Emphasis on animation and visual polish (shadows, gradients, transitions)

Limitations

  • Only applicable to Quickshell with the specific Obelisk configuration
  • Requires prior knowledge of QML and Quickshell components
  • May be difficult to adapt to other shells or desktop environments
When to use it

Use when building or customizing desktop widgets for the Obelisk Quickshell environment to ensure consistency, reusability, and high aesthetic quality.

When not to use it

Do not use for general QML development outside of Quickshell or for other shell configurations without adaptation.

Examples

System Monitor Widget
Create a new system monitor widget for the Obelisk Quickshell shell that shows CPU, RAM, and network usage using the SystemInfo service. Follow the design principles from the frontend design skill.
Custom Launcher
Design a minimalist application launcher widget for Quickshell's Obelisk configuration. It should have a search bar, display frequently used apps, and use OPanel for the dropdown. Use the Theme tokens for styling.
Weather Widget
Implement a weather widget for the Quickshell desktop that fetches data from a service, displays current conditions and forecast, and uses smooth transitions. Ensure it integrates with the Obelisk theme.

Frontend Design Skill

This skill guides the creation of high-quality QML interfaces for Quickshell, specifically tailored to the @quickshell/.config/quickshell/ configuration. It combines technical Quickshell expertise with high-end aesthetic design thinking.

Design Thinking

Before coding, commit to a BOLD aesthetic direction that fits the "Obelisk" shell but pushes it further:

  • Tone: Pick a flavor: brutally minimal, retro-futuristic, refined luxury, industrial/utilitarian, or organic.
  • Differentiation: What is the one thing that makes this widget UNFORGETTABLE?
  • Intentionality: Bold maximalism and refined minimalism both work; the key is executing with precision.

Quickshell Design Principles

  • Native Integration: Widgets must look and feel like part of the existing "Obelisk" shell.
  • Theming: Rigorously use the Theme singleton (qs.Config) for all colors, sizes, radii, and fonts.
  • Reusability: Use existing components from qs.Components (OText, OButton, IconButton, OPanel) whenever possible.
  • Reactive: Bind properties to Services (qs.Services) for live data.

Technical Foundation

Always include necessary imports:

import QtQuick
import QtQuick.Layouts
import Quickshell
import Quickshell.Wayland
import qs.Config      // Theme, Settings
import qs.Components  // OText, OButton, OPanel, etc.
import qs.Services    // Core, SystemInfo, WM

Theming Guidelines (Theme.qml)

  • Backgrounds: Theme.bgColor, Theme.bgElevated, Theme.bgElevatedAlt
  • Accents: Theme.activeColor, Theme.onHoverColor, Theme.critical (red), Theme.warning (orange)
  • Text: Theme.textActiveColor, Theme.textInactiveColor
  • Spacing: Theme.spacingXs to Theme.spacingXl
  • Radii: Theme.itemRadius, Theme.radiusMd, Theme.radiusLg

Aesthetics & Polish

  • Typography: Stick to Theme.fontFamily (CaskaydiaCove) and Theme.iconFontFamily. Use OText variants for hierarchy.
  • Motion: Use Behavior on <property> with Theme.animationDuration and Easing.InOutQuad for all transitions. Focus on staggered reveals and smooth width/opacity changes.
  • Visual Details: Create depth. Use RectangularShadow or MultiEffect for subtle shadows. Use Canvas for custom gradient borders (see CardStyling.qml).
  • Avoid "AI Slop": No predictable layouts or generic "purple on white" color schemes. Stay true to the project's Catppuccin/Dracula/Obelisk color palettes.

Component Usage

  • OText: OText { text: "Label"; bold: true; muted: true }
  • IconButton: For circular icon-only buttons.
  • OPanel: For dropdowns/menus. Always provide a unique panelNamespace.
  • ExpandingPill: Use for collapsible groups of buttons (like PowerMenu or Workspaces).

New Modules

When creating a new widget:

  1. Place it in Modules/<Category>/<Name>.qml.
  2. Use pragma ComponentBehavior: Bound.
  3. Example Pattern:
pragma ComponentBehavior: Bound
import QtQuick
import QtQuick.Layouts
import qs.Config
import qs.Components

Rectangle {
    color: Theme.bgElevated
    radius: Theme.itemRadius
    border.color: Theme.borderLight
    border.width: 1

    ColumnLayout {
        anchors.fill: parent
        anchors.margins: Theme.spacingMd
        spacing: Theme.spacingSm

        OText {
            text: "Widget Title"
            bold: true
            size: "lg"
        }
        // ... content
    }
}
