TAdvSmoothTileList: Designing Smooth, Animated Tile Layouts

Troubleshooting layout and performance issues in the TMS Software TAdvSmoothTileList component requires understanding its architectural foundation. Because this VCL component relies heavily on GDI+ for rendering complex gradients, transparency, and smooth animations, it can become a bottleneck if not configured properly.

The most common issues, along with actionable solutions to optimize and resolve them, are detailed below. 🧱 Layout Inconsistencies and Truncation

Layout issues usually stem from a mismatch between content size, tile dimensions, or High-DPI scaling conflicts. Tiles Overlapping or Misaligned:

Cause: Unsynchronized Columns and Rows properties or hardcoded pixel coordinates that fail when tiles resize.

Fix: Set Layout configurations to adapt dynamically. Verify that Columns and Rows match the scale of your parent container. Avoid explicit tile positioning when relying on automatic flow layouts. Text or HTML Clipping:

Cause: The built-in lightweight HTML engine cannot fit the raw text into the tile’s bounding box.

Fix: Ensure that font size properties are accounted for. You can either increase the tile’s Width and Height or wrap text content using standard HTML line breaks (
) to match the estimated tile width. High-DPI and Multi-Monitor Blurring:

Cause: Older versions of the component pack have known bugs handling multi-monitor DPI scaling.

Fix: Upgrade to the latest version of the TMS VCL UI Pack, which includes overhauled high-DPI scaling calculations for smooth controls. Ensure the form’s Scaled property is set to True. ⚡ Performance Bottlenecks and Laggy Animations

Because every visual element uses alpha transparency and smooth anti-aliased drawing, performance can degrade rapidly when handling large datasets or excessive updates. Flickering or Heavy Lag During Updates:

Cause: The control is forced to recalculate positions and repaint the GDI+ canvas after every individual modification.

Fix: Wrap bulk changes (adding, deleting, or modifying tiles) inside BeginUpdate and EndUpdate blocks.

AdvSmoothTileList1.BeginUpdate; try // Perform multi-tile modifications or loading here finally AdvSmoothTileList1.EndUpdate; end; Use code with caution. Slow Initial Load and Maximization Delays:

Cause: Lazy-loading frames or heavy property extraction triggering too early during the first render or maximization transition.

Fix: Separate heavy data retrieval from the initial UI load. If using custom content visualizers, ensure they do not perform synchronous database queries or complex file I/O operations inside layout initialization blocks. Stuttering Animations:

Cause: Excessive graphical overhead from shadow blur, complex gradients, or an oversized global ImageList / PictureContainer.

Fix: Toggle intensive visual features off if performance drops. Try setting Animation properties to False or reducing the shadow complexity (GlowAnimation := False). Ensure background images are pre-scaled to the exact tile dimensions instead of forcing GDI+ to stretch them on the fly. 🔍 Diagnostic Checklist for Developers
