go walk 消息窗

walk.MsgBox

消息窗

func MsgBox(owner Form, title, message string, style MsgBoxStyle) int

owner Form 父窗体句柄
title 消息窗的标题
message 消息内容
style 消息窗的样式

walk.MsgBox(
        mw,
        "Title",
        "Message",
        walk.MsgBoxServiceNotification)

参数style 取值比较多可参照 walk 包下面的 messagebox.go 中定义的

消息按钮事件的触发

walk.MsgBox 方法的返回值是int ，这个返回值就是点击消息窗按钮时返回的，返回用户点击的具体的按钮的Id,可以通过判断这个来触发点击回调。具体实现如下,部分关键代码：

   OnClicked: func() {
            cmd=walk.MsgBox(
                mw,
                "Title",
                "Message",
                walk.MsgBoxYesNoCancel)
            switch cmd {
            case walk.DlgCmdYes:
                le.SetText("click 是")
            case walk.DlgCmdCancel:
                le.SetText("click 取消")
            case walk.DlgCmdNo:
                le.SetText("click 否")
            }
        },
