After startup:

Click Maximize and then Restore to the original window. The blank disappears:

package main

import (
    "fmt"
    "os"

    "github.com/lxn/walk"
    . "github.com/lxn/walk/declarative"
)

type MyMainWindow struct {
    main *walk.MainWindow
    sbi  *walk.StatusBarItem
}

var mw *MyMainWindow

func main() {
    mw = new(MyMainWindow)
    MW := MainWindow{
        AssignTo: &mw.main,
        Title:    "客户端",
        Icon:     "../goFtp/images/client.ico",

            },
        },
    }

    if _, err := MW.Run(); err != nil {
        fmt.Fprintln(os.Stderr, err)
        os.Exit(1)
    }
}

There currently are some problems with ToolBar. Until they are fixed you can add your ToolBar to the list of Children of the MainWindow. Just be sure to wrap it on it's own in a Composite, or it will misbehave again.
