Core Expertise

GPUI Layout System

Flexbox Layout

GPUI uses a flexbox-based layout system similar to CSS flexbox:

use gpui::*;

div()
    .flex()                    // Enable flexbox
    .flex_row()               // Direction: horizontal
    .gap_4()                  // Gap between children
    .items_center()           // Align items vertically
    .justify_between()        // Distribute space
    .child(/* ... */)
    .child(/* ... */)

Layout Properties:

• flex(): Enable flex layout
• flex_row(), flex_col(): Set flex direction
• flex_wrap(): Allow wrapping
• flex_1(), flex_grow(), flex_shrink(): Flex sizing
• gap(), gap_x(), gap_y(): Spacing between items
• items_start(), items_center(), items_end(), items_stretch(): Cross-axis alignment
• justify_start(), justify_center(), justify_end(), justify_between(), justify_around(): Main-axis alignment
• self_start(), self_center(), self_end(): Individual item alignment

Grid Layout

div()
    .grid()
    .grid_cols_3()           // 3 columns
    .gap_4()                 // Gap between cells
    .child(/* item 1 */)
    .child(/* item 2 */)
    .child(/* item 3 */)

Absolute Positioning

div()
    .relative()              // Positioning context
    .size_full()
    .child(
        div()
            .absolute()      // Absolute positioning
            .top_4()
            .right_4()
            .child("Badge")
    )

Sizing

div()
    .w_full()               // Width: 100%
    .h_64()                 // Height: 16rem
    .min_w_32()             // Min width: 8rem
    .max_w_96()             // Max width: 24rem
    .size(px(200.))         // Fixed size: 200px
