Toolbar
The toolbar widget creates a row of action buttons using
icons to represent each. The widget.NewToolbar(...)
constructor function takes a list of widget.ToolbarItem
parameters. The builtin types of toolbar items are action,
separator and spacer.
The most used item is an action that is created using the
widget.NewToolbarItemAction(..) function. An action takes
two parameters, first being the icon resource to draw and
the latter is the func() to call when tapped. This creates
a standard toolbar button.
You can use widget.NewToolbarSeparator() to create a
small divider between items in a toolbar (usually a thin
vertical line). Lastly you can use widget.NewToolbarSpacer()
to create a flexible space between elements. This is most
useful to right align the toolbar items that are listed
after the spacer.
A toolbar should always be at the top of the content area
so it’s normal to add it to a fyne.Container using the
layout.BorderLayout to align it above other content.
package main
import (
"log"
"fyne.io/fyne/v2/app"
"fyne.io/fyne/v2/container"
"fyne.io/fyne/v2/theme"
"fyne.io/fyne/v2/widget"
)
func main() {
myApp := app.New()
myWindow := myApp.NewWindow("Toolbar Widget")
toolbar := widget.NewToolbar(
widget.NewToolbarAction(theme.DocumentCreateIcon(), func() {
log.Println("New document")
}),
widget.NewToolbarSeparator(),
widget.NewToolbarAction(theme.ContentCutIcon(), func() {}),
widget.NewToolbarAction(theme.ContentCopyIcon(), func() {}),
widget.NewToolbarAction(theme.ContentPasteIcon(), func() {}),
widget.NewToolbarSpacer(),
widget.NewToolbarAction(theme.HelpIcon(), func() {
log.Println("Display help")
}),
)
content := container.NewBorder(toolbar, nil, nil, nil, widget.NewLabel("Content"))
myWindow.SetContent(content)
myWindow.ShowAndRun()
}
