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},
