Cogent Core: A New GUI Framework for Go
GUI framework written in Go that allows you Code Once, Rune Everywhere (Core) (macOS, Windows, Linux, iOS, Android and web)
The same Cogent Core app running on many devices using the same code:
- Simple Hello World app:
package main
import "cogentcore.org/core/core"
func main() {
b := core.NewBody()
core.NewButton(b).SetText("Hello, World!")
b.RunMainWindow()
}
- Supports all usual GUI widgets:
core.NewButton(b).SetText("Send").SetIcon(icons.Send).OnClick(func(e events.Event) {
core.MessageSnackbar(b, "Message sent")
})
core.NewText(b).SetText("Name:").SetTooltip("Enter your name in the text field")
core.NewTextField(b).SetPlaceholder("Jane Doe")
value := 0.5
spinner := core.Bind(&value, core.NewSpinner(b))
slider := core.Bind(&value, core.NewSlider(b))
spinner.OnChange(func(e events.Event) {
slider.Update()
})
slider.OnChange(func(e events.Event) {
spinner.Update()
})
core.NewColorButton(b).SetColor(colors.Orange)
type language struct {
Name string
Rating int
}
sl := []language{{"Go", 10}, {"Python", 5}}
core.NewTable(b).SetSlice(&sl).OnChange(func(e events.Event) {
core.MessageSnackbar(b, fmt.Sprintf("Languages: %v", sl))
})
- Interactive plots of data
type Data struct {
Time float32
Users float32
Profit float32
}
plotcore.NewPlotEditor(b).SetSlice([]Data{
{0, 500, 1520},
{1, 800, 860},
{2, 1600, 930},
{3, 1400, 682},
})
