MessageDialog {
id: messageDialog
title: "Tcp Server Connection Status"
text: "Connection to" server_name_id.text "Failed"
icon: "Critical"
onAccepted: {
console.log("What is the issue. Please check")
//server_name_id.enabled = true;
//server_port_id.enabled = true;
tcpip_connect_id.checked = false
}
visible :false
}
