Module layout 

Simple layout helpers for positioning widgets.

Structs

GridLayout

Grid-based layout for a plugin UI.

GridWidget

A widget placed in a grid layout.

HeaderTitles

Title band drawn above a layout. The title slot renders larger / brighter on the left of the band; the subtitle slot renders smaller / dimmer on the right. Each slot is independently optional - set either, both, or neither.

KnobDef

A widget definition for the layout - either explicit type or auto-detected.

KnobRow

A row of widgets with an optional section label.

PluginLayout

Layout configuration for a plugin UI.

Section

A group of widgets with an optional section label.

Enums

Layout

Layout variant for editor dispatch.

WidgetKind

Explicit widget type for layout overrides.

Constants

AUTO

Sentinel value for auto-placed grid widgets.

DROPDOWN_BOX_HEIGHT

Pixel height of the dropdown button box (the closed state - clicking this opens the popup). Both widgets::draw_dropdown (paint side) and interaction::open_dropdown (popup-anchor math) need to agree.

GRID_DEFAULT_CELL_SIZE

Default cell size in logical points when GridLayout::build is called without .with_cell_size(...). Matches the scaffolded plugin’s pre-refactor value so untouched scaffolds render the same as before.

GRID_GAP

GRID_HEADER_H

GRID_PADDING

GRID_SECTION_H

HEADER_HEIGHT

Pixel height of the title-bar header widgets::draw_header paints at the top of the editor.

ROWS_COLUMN_GAP

Horizontal gap between adjacent widgets in a row. The full pitch between widget origins is knob_size + ROWS_COLUMN_GAP.

ROWS_LAYOUT_TOP

Y-offset of the first row below the header. The 4-pixel gap between HEADER_HEIGHT and ROWS_LAYOUT_TOP is the breathing room between the title bar and the first row of widgets.

ROWS_ROW_GAP

Vertical gap below a row. The full pitch between row origins is knob_size + ROWS_ROW_GAP.

ROWS_SECTION_LABEL_HEIGHT

Vertical pixels reserved for a section label (Row::label) drawn above its row.

Functions

compute_section_offsets

Compute cumulative section-label pixel offsets per row.

meter

Level meter widget.

section

Create a labeled section of widgets for GridLayout::build().

selector

Click-to-cycle selector widget.

Horizontal slider widget.

toggle

Toggle switch widget.

widgets

Wrap bare widgets into an unlabeled section (no section header).

xy_pad

XY pad controlling two parameters.
