Checkbox: checkboxes
Build checkboxes with Checkbox. This page includes a runnable example, all props, and behavior constraints.
Complete example
Complete environment setup first. Copy this complete main.go and run go run ..
go
package main
import (
"fmt"
"github.com/dxui-org/dxui"
"log"
)
func main() {
checked := false
app := dxui.NewApp(dxui.AppOptions{
Title: "Checkbox",
Width: 640,
Height: 480,
Background: dxui.RGBA(248, 250, 252, 255),
})
if err := app.Run(func() dxui.View {
return dxui.Box(
dxui.BoxProps{
Gap: 16,
Style: dxui.Style{
Padding: dxui.Padding(24),
},
},
dxui.Box(
dxui.BoxProps{
Gap: 12,
},
dxui.Checkbox(
dxui.CheckboxProps{
Checked: checked,
OnChange: dxui.Assign(&checked),
},
dxui.Label("Accept terms"),
),
dxui.Label(fmt.Sprint(checked)),
),
)
}); err != nil {
log.Fatal(err)
}
}Parameters and API
go
func Checkbox(props CheckboxProps, label View) View| Field | Type | Purpose, defaults, and constraints |
|---|---|---|
Key | string | Stable unique identity within one parent; empty by default. Use business IDs in dynamic lists, not changing indices. |
Style | Style | Local layout, paint, and text styling; zero uses intrinsic sizes and theme defaults. |
Token | ComponentToken | Component theme entry; empty selects its default. |
States | StateStyles | Paint patches for actual interaction states; cannot fabricate state or change layout. |
Pointer | PointerBehavior | Defaults to PointerAuto; PointerNone excludes the entire subtree from pointer participation, unlike Disabled. |
Checked | bool | Controlled boolean, default false; accept changes in OnChange. |
Disabled | bool | Defaults to false; true removes focus and cancels interaction on interactive components. |
OnChange | func(bool) | Proposes a complete new value; write it to state for the next build. See behavior for nil callbacks. |
Behavior and limitations
Accepts one label View. Checked is controlled; pointer or Space proposes toggling it. Nil OnChange does not change the business value and is not Disabled. Disabled removes focus and cancels pressing. No tri-state support.
All components share identity, style, and pointer rules. See full declarations for referenced enums, structs, and comments. Running examples explains build verification.
