- Reimplement previews using nested UISceneNodes with isolated styles and resources. - Preserve live XML/CSS editing, unsaved buffer previews, external file watching, and project resource loading. - Use UIApplication for initialization, font resolution, and offscreen rendering support. - Enable Breeze by default, add a menu toggle, and replace --use-app-theme with --disable-app-theme. - Automatically preserve declared project viewport dimensions, with an optional override to use the preview split size. - Support embedded HTML documents inside WebView XML elements. - Fix fading window shadows and shutdown with visible modal dialogs. - Update documentation and add regression coverage.

# UI editor
|
|
|
|
`eepp-UIEditor` previews native eepp XML layouts and CSS while you edit them. Open a layout,
|
|
a stylesheet, or a project from the menus or command line:
|
|
|
|
```sh
|
|
bin/eepp-UIEditor --xml /path/to/layout.xml --css /path/to/style.css
|
|
bin/eepp-UIEditor --project /path/to/project.xml
|
|
bin/eepp-UIEditor --xml /path/to/layout.xml --disable-app-theme
|
|
```
|
|
|
|
The preview uses the bundled Breeze stylesheet by default and opens it in an editor tab.
|
|
Use `--disable-app-theme` to start without it, or toggle **View → Use app theme (Breeze)** at runtime.
|
|
The toggle refreshes the preview with or without Breeze, preserves project and embedded styles,
|
|
and leaves the editor shell's theme unchanged. Use
|
|
`--pixel-density 2` to check HiDPI behavior and `--prefers-color-scheme light`, `dark`, or `system`
|
|
to select the preview's color preference.
|
|
|
|
## Live editing
|
|
|
|
XML and CSS changes in the built-in editor, including undo and redo, rebuild the preview after
|
|
350 ms of inactivity. Unsaved documents are parsed directly from memory, preserving their original
|
|
file URI for relative assets, CSS imports, and author font faces. Incomplete XML keeps the last
|
|
valid preview and logs a parse error to the console.
|
|
|
|
The selected XML, project CSS, and enabled base CSS are also watched for external changes,
|
|
including replacement files written by editors that save through a rename. Dirty editor buffers
|
|
take precedence over disk changes. New layouts have temporary backing files; Save prompts for a
|
|
permanent destination, as does Save All for edited new layouts. Save As preserves an existing source
|
|
file.
|
|
|
|
## Projects
|
|
|
|
Project paths are relative to the project file's directory, or to an optional `basepath` resolved
|
|
against that directory. Opening a project does not change the application's working directory.
|
|
|
|
```xml
|
|
<uiproject>
|
|
<basepath>assets</basepath>
|
|
<font><path>fonts</path></font>
|
|
<drawable><path>images</path></drawable>
|
|
<widget>
|
|
<customWidget name="GameScreen" replacement="RelativeLayout" />
|
|
</widget>
|
|
<layout width="1920" height="1080">
|
|
<path>layouts</path>
|
|
</layout>
|
|
<stylesheet path="style.css" />
|
|
</uiproject>
|
|
```
|
|
|
|
Font, drawable, and layout paths can name individual files or directories. `uitheme` elements can
|
|
name texture-atlas theme files. Custom widget replacements allow layouts using application-specific
|
|
widgets to be previewed with known native controls. The Layouts menu selects between project layouts.
|
|
|
|
Projects with positive layout width and height automatically use a fixed viewport at those pixel
|
|
dimensions, scaled down and centered when necessary to fit the preview split. Layout, viewport
|
|
units, and media queries use the project dimensions. Disable **View → Use project viewport** to
|
|
use the split's available size without scaling. Projects without valid dimensions and standalone
|
|
layouts use the split's size by default. F1 can resize the native window toward the project dimensions.
|
|
