Building Animated Interfaces with TAdvGlowButton

Customizing TAdvGlowButton — Tips, Tricks, and Best PracticesTAdvGlowButton is a visually rich, highly customizable button component commonly used in Delphi applications (part of TMS components) to create modern, attention-grabbing UI controls. It combines flexible styling, glow/hover effects, icons, and animation options to help you build interfaces that feel polished and responsive. This article covers practical tips, advanced tricks, and best practices to get the most out of TAdvGlowButton — from basic styling to accessibility, performance, and real-world usage patterns.

Overview: What TAdvGlowButton Offers

TAdvGlowButton provides:

• Customizable glow and hover effects with configurable color, intensity, and blur.
• Multiple visual states (normal, hot/hover, pressed, disabled).
• Support for glyphs/icons alongside captions.
• Rounded corners and flat/3D looks with brush and pen options.
• Animation and transition support for smooth state changes.
• Events for mouse, keyboard, and focus to implement interactive behaviors.

Getting Started: Basic Properties You Should Know

• Caption — the text shown on the button.
• Glyph/Icon — use an image or vector symbol for visual identity.
• GlowColor — sets the color of the glow effect.
• GlowSize/GlowBlur — controls the radius and softness of the glow.
• HotColor/PressedColor — colors for hover and pressed states.
• ShapeType/CornerRadius — for rounded or custom button shapes.
• Flat — toggles flat vs. raised appearance.
• AnimationDuration — how long transitions take.
• Enabled — allow default disabled appearance or customize DisabledColor.

Practical tip: start by setting a consistent base style (font, base color, corner radius) across all buttons for UI coherence; then vary glow and iconography for emphasis.

Styling and Theming

1. Color palette:

   • Use a limited palette (primary, secondary, accent) and choose GlowColor as a slightly brighter accent for emphasis.
   • For dark themes, prefer lighter glows (white/soft cyan); for light themes, slightly darker glows (soft blue/indigo).

2. Typography:

   • Keep button captions short (1–4 words).
   • Use bold for primary actions; smaller or regular weight for secondary actions.

3. Icons and spacing:

   • Use consistent glyph sizes (e.g., 16–20 px) and padding.
   • Align icon left with caption center-left to create consistent visual rhythm.

4. Shape and depth:

   • Rounded corners with 4–8 px radius work for modern UIs.
   • For subtle emphasis, use a shallow glow and small blur; for call-to-action, increase glow size and saturation.

Advanced Visual Techniques

• Layered glows: combine multiple glow layers by placing multiple TAdvGlowButtons with transparent backgrounds or by drawing additional glow in the button’s OnPaint (if supported).
• Animated transitions: set AnimationDuration to moderate values (120–250 ms) for smooth but snappy feedback.
• Dynamic glow color: change GlowColor at runtime in response to application state (e.g., success = green, error = red) for contextual feedback.
• Gradient fills: where supported, apply subtle gradients to the face of the button to add depth while keeping the glow soft.

Code example — change glow color on hover (pseudo-Delphi):

procedure TForm1.AdvGlowButton1MouseEnter(Sender: TObject); begin   AdvGlowButton1.GlowColor := clSkyBlue;   AdvGlowButton1.Invalidate; end; procedure TForm1.AdvGlowButton1MouseLeave(Sender: TObject); begin   AdvGlowButton1.GlowColor := clBtnFace;   AdvGlowButton1.Invalidate; end;

Functionality Tips

• Use different button roles: primary (strong glow, bold caption), secondary (flat, minimal glow), destructive (red glow or red border).
• Keyboard accessibility: ensure TabOrder includes buttons and set Default/Cancel behavior when appropriate.
• Tooltips: pair complex or icon-only buttons with clear tooltips to explain action.
• State feedback: combine glow with short animations or icon changes to indicate loading, success, or failure.

---

Performance Considerations

• Avoid overly large GlowSize/GlowBlur values for many buttons — rendering cost increases with blur radius.
• Reduce animation duration or disable animation for lists of many buttons (e.g., in a grid) to keep UI responsive.
• Cache complex glyphs as bitmaps at the required size rather than resizing vector icons repeatedly.

---

Accessibility & UX Best Practices

• Contrast: ensure caption and glow provide sufficient contrast against backgrounds (WCAG recommendations).
• Hit target size: keep buttons at least 44×44 px for touch devices.
• Focus indication: in addition to glow, provide a distinct keyboard focus rectangle or change border thickness for keyboard users.
• Labels: avoid using glow alone to indicate state — pair with text or icon changes for users with visual impairments.

---

Common Customization Scenarios

1. Icon-only toolbar button:
   • Use a moderate glow, no caption, constant tooltip, and increase hit area with padding.
2. Call-to-action (CTA):
   • Bold caption, larger corner radius, saturated glow, and subtle bounce animation on show.
3. Disabled/destructive states:
   • Use desaturated colors and lower glow intensity; for destructive, use red hues with confirmation dialogs.

Troubleshooting

• Glow not showing: verify component’s parent background and ensure opacity/transparency settings aren’t hiding the glow.
• Flicker on resize: use double buffering or set the button’s DoubleBuffered property if available.
• Inconsistent rendering across themes: test under light/dark OS themes and adjust color choices programmatically.

---

Example: A Small Style Library (Suggested Values)

• Primary button: GlowColor = clSkyBlue, GlowSize = 8, CornerRadius = 6, AnimationDuration = 180ms
• Secondary: GlowColor = clSilver, GlowSize = 4, CornerRadius = 4, AnimationDuration = 120ms
• Destructive: GlowColor = clRed, GlowSize = 6, CornerRadius = 6, AnimationDuration = 150ms

---

When Not to Use TAdvGlowButton

• Extremely minimalistic UIs where any glow would break aesthetic.
• Performance-critical lists with hundreds of items — use simpler controls there.
• Environments where platform-native controls are required for compliance or consistent OS look.

---

Final Best Practices (Quick Checklist)

• Keep a consistent base style across the app.
• Use glow for emphasis, not decoration.
• Ensure accessibility: contrast, keyboard focus, tooltips.
• Test performance on target hardware.
• Animate subtly and purposefully.
