一直用go写后台服务用，几乎没有写过gui程序，近日对各种的golang的gui库了解了一下，最后选择了用govcl试试，感觉还是不错的。用起来很顺手，下面把我写的基于MsTscAx控件的远程桌面程序发出来和大家共享下，一共就50行代码，
效果图如下：
````
package main
import (
"syscall"
"unsafe"
"github.com/ying32/govcl/vcl/types/colors"
"github.com/go-ole/go-ole"
"github.com/go-ole/go-ole/oleutil"
_ "github.com/ying32/govcl/pkgs/winappres"
"github.com/ying32/govcl/vcl"
)
var Form1 *TForm1
var atlDll = syscall.NewLazyDLL("atl.dll")
var AtlAxAttachControl = atlDll.NewProc("AtlAxAttachControl")
func main() {
vcl.Application.Initialize()
vcl.Application.CreateForm(&Form1)
vcl.Application.Run()
}
type TForm1 struct {
*vcl.TForm
Rdp1 RdpPanel
}
type RdpPanel struct {
*vcl.TPanel
rdp *ole.IDispatch
}
func (f *TForm1) OnFormCreate(sender vcl.IObject) {
f.SetCaption("windows远程桌面")
f.SetBounds(10, 10, 1024, 800)
f.Rdp1.Initrdp(f, 0, 0, 1024, 768, "192.168.2.28", "administrator", "pass")
}
func (rp *RdpPanel) Initrdp(f *TForm1, x, y, w, h int32, ip, username, pass string) {
ole.CoInitialize(0)
rp.TPanel = vcl.NewPanel(f)
rp.SetParent(f)
rp.SetBounds(x, y, w, h)
rp.SetParentBackground(false)
rp.SetColor(colors.ClRed)
unknown, _ := oleutil.CreateObject("MsTscAx.MsTscAx.2")
rp.rdp = unknown.MustQueryInterface(ole.IID_IDispatch)
AtlAxAttachControl.Call(uintptr(unsafe.Pointer(&unknown.RawVTable)), rp.Handle(), 0)
oleutil.PutProperty(rp.rdp, "server", ip)
oleutil.PutProperty(rp.rdp, "username", username)
set, _ := oleutil.GetProperty(rp.rdp, "AdvancedSettings")
set.ToIDispatch().PutProperty("ClearTextPassword", pass)
oleutil.MustCallMethod(rp.rdp, "connect")
ole.CoUninitialize()
}
````
最后，如果也有用govcl的小伙伴，希望能提供一下支持多标签页的方法。不胜感激~
