Text

using Fugl
using Fugl: Text

function MyApp()
    Container(
        Text("Some Text")
    )
end

Wrapping

The Text component support wrapping by default.

using Fugl
using Fugl: Text

function MyApp()
    Container(
        Text("Some strings may be too long to fit, and must be drawn over multiple lines.")
    )
end

screenshot(MyApp, "text_wrap.png", 400, 150);

Text Clipping

By setting wrap_text=false, text will be rendered on a single line and clipped if it exceeds the container width, similar to VS Code's sidebar behavior.

using Fugl
using Fugl: Text

function MyApp()
    Container(
        Column([
            Text("This text will wrap normally because wrap_text is true by default", wrap_text=true),
            Text("This very long text will be clipped instead of wrapping to multiple lines", wrap_text=false)
        ], spacing=10.0)
    )
end

screenshot(MyApp, "text_clip.png", 400, 150);

Horizontal Alignement

using Fugl
using Fugl: Text

function MyApp()
    Container(
        Column([
            Text("Align left",   horizontal_align=:left),
            Text("Align center", horizontal_align=:center),
            Text("Align right",  horizontal_align=:right)
        ], padding=0.0, spacing=0.0);
        style=ContainerStyle(;padding=0.0f0)
    )
end

screenshot(MyApp, "text_align.png", 812, 150);

Vertical Alignement

using Fugl
using Fugl: Text

function MyApp()
    Container(
        Row([
            Text("Align top",    vertical_align=:top),
            Text("Align middle", vertical_align=:middle),
            Text("Align bottom", vertical_align=:bottom)
        ], padding=0.0, spacing=0.0);
        style=ContainerStyle(;padding=0.0f0)
    )
end

Word Wrapping with Vertical Alignment

Word wrapping also respects vertical alignment, centering or positioning the entire wrapped text block as a unit.

using Fugl
using Fugl: Text

function MyApp()
    Container(
        Row([
            Container(
                Text("This long text will wrap to multiple lines and be aligned as a block at the top",
                     vertical_align=:top, horizontal_align=:center, wrap_text=true),
                style=ContainerStyle(background_color=Vec4f(0.3, 0.3, 0.6, 1.0))
            ),
            Container(
                Text("This long text will wrap to multiple lines and be centered as a complete block in the middle",
                     vertical_align=:middle, horizontal_align=:center, wrap_text=true),
                style=ContainerStyle(background_color=Vec4f(0.6, 0.4, 0.4, 1.0))
            ),
            Container(
                Text("This long text will wrap to multiple lines and be positioned as a block at the bottom",
                     vertical_align=:bottom, horizontal_align=:center, wrap_text=true),
                style=ContainerStyle(background_color=Vec4f(0.4, 0.6, 0.4, 1.0))
            )
        ]),
    )
end

Text Style

Style is handeled by the TextStyle struct.

using Fugl
using Fugl: Text

my_style = TextStyle(
    # font_path="SomeFont.ttf",
    size_px=32,
    color=Vec4f(0.1, 0.7, 0.7, 1.0), # RGBA
)


function MyApp()
    Container(
        Text("Some text"; style=my_style)
    )
end

screenshot(MyApp, "text_style.png", 812, 150);

Text Rotation

Text can be rotated by wrapping it with the Rotate component. Positive angles rotate counter-clockwise.

using Fugl
using Fugl: Text, Rotate

function MyApp()
    Container(
        Row([
            Rotate(Text("0°", horizontal_align=:center, vertical_align=:middle), rotation_degrees=0.0f0),
            Rotate(Text("45°", horizontal_align=:center, vertical_align=:middle), rotation_degrees=45.0f0),
            Rotate(Text("90°", horizontal_align=:center, vertical_align=:middle), rotation_degrees=90.0f0)
        ], padding=20.0, spacing=20.0)
    )
end
