DevExpress VCL Subscription 22.2.3

New Vector Graphics for UI Elements
We continue to enhance our UI controls to better support high DPI (4K+) devices and improve rendering regardless of DPI settings. The following controls can now display SVG graphics within UI elements, menus, and dialogs:
- Chart View in ExpressQuantumGrid
- Data Editors
- PDF Viewer
- Rich Text Editor
- Scheduler
- Spreadsheet
- TreeList
Our VCL controls will display SVG icons by default in v23.1. Enable our new global dxUseVectorIcons option in the initialization section of the main application unit to display SVG icons. This particular option has been enabled in our demos so you can see the difference when compared to previous versions.


"Light" Style Rendering
Clean, simple, and minimalistic UI design is a trend in modern software development. To address this trend, we added a "light" style rendering mode to our VCL Data Grid (ExpressQuantumGrid), and will support this mode in other UI controls in v23.1. When used, our VCL UI controls are rendered without double or thick borders, extra outlines, and other visual noise.
Call the TdxVisualRefinements.ApplyLightStyle class procedure in the initialization section of the main application unit to enable "light" style rendering.


New Sizable Panel
Our new Panel (TdxPanel) control is designed to break down a form into multiple resizable regions divided by one-pixel splitters. You can place a control on such a panel without gaps or double borders and create lightweight application layouts as needs dictate.


VCL Rendering Engine for Modern App-Design Paradigms and New Skins - Phase #1
Modern app-design trends and new themes like Windows 11 required us to rewrite our rendering engine for both greater performance and UI flexibility - the old schema could not address additional usage scenarios introduced by Windows 11. Our new "Light Style" rendering mode also required updates to old drawing schemas. We expect to deliver our new VCL rendering engine in our next major update (v23.1). Once we ship the new engine, we'll be in position to deliver new vector skins and help you ship more compelling/elegant user interfaces.
With this release (v22.2), we've completed the initial phase of our strategy:
- Fixed 40+ component layout and image-related issues across all VCL product demos and associated UI controls.
- Gathered unsupported UI scenarios and performance requirements for our 2023 rendering engine (to support the Windows 11 skin, new skin and palette selectors, "Light Style" mode, etc).

This list includes all issues that were resolved in 22.2.3.
