Button
The button widget can contain text, an icon or both, the constructor
functions are widget.NewButton()
and widget.NewButtonWithIcon()
.
To create a text button there are just 2 parameters, the string
content
and a 0 parameter func()
that will be called when the button is tapped.
See the example for how that can be created.
The button constructor with an icon includes an additional parameter
which is the fyne.Resource
which contains the icon data.
The builtin icons within the theme
package all adapt appropriately
to a change in theme. You can pass in your own image if it is loaded
as a resource - helpers such as fyne.LoadResourceFromPath()
may assist,
though bundling resources is recommended where possible.
To create a button with only an icon you should pass “” as the label
parameter to widget.NewButtonWithIcon()
.
package main
import (
"log"
"fyne.io/fyne/v2/app"
"fyne.io/fyne/v2/widget"
//"fyne.io/fyne/v2/theme"
)
func main() {
myApp := app.New()
myWindow := myApp.NewWindow("Button Widget")
content := widget.NewButton("click me", func() {
log.Println("tapped")
})
//content := widget.NewButtonWithIcon("Home", theme.HomeIcon(), func() {
// log.Println("tapped home")
//})
myWindow.SetContent(content)
myWindow.ShowAndRun()
}
