Form

The form widget is used to lay out many input fields with labels and optional cancel and submit buttons. In its most bare form it aligns labels to the left of each input widget. By setting OnCancel or OnSubmit the form will add a button bar with the specified handlers called when appropriate.

The widget can be created with widget.NewForm(...) passing a list of widget.FormItems, or by using the &widget.Form{} syntax illustrated in the example. There is also a helpful Form.Append(label, widget) that can be used for an alternative syntax.

In this example we create two entries, one of which is a “multiline” (like HTML TextArea) to hold values. There is an OnSubmit handler which prints the information before closing the window and therefore the application.
