golang imgui Layout中，布局里不能使用if判断，请问怎么解决

Answer 1

或许可以用种清奇点的思路

var windLay  类型
if vKey== "" { 
        windLay = giu.Layout{
            giu.Row( // 增加键名
                giu.Label("键名"),
                giu.InputText(&vKey),
            ),
        g.Row( // 
            giu.Label("值"),
            giu.InputText(&vVal),
        ),
    }    
} else{
    windLay = giu.Layout{

        g.Row( 

            giu.Label("值"),

            giu.InputText(&vVal),

        ),

    }
}
