gowut是一个 功能全面、简单易用、平台无关的纯go语言WebUI工具包。

例子如下:

package main    import (          "code.google.com/p/gowut/gwu"          "strconv"  )    type MyButtonHandler struct {          counter int          text    string  }    func (h *MyButtonHandler) HandleEvent(e gwu.Event) {          if b, isButton := e.Src().(gwu.Button); isButton {                  b.SetText(b.Text() + h.text)                  h.counter++                  b.SetToolTip("You've clicked " + strconv.Itoa(h.counter) + " times!")                  e.MarkDirty(b)          }  }    func main() {          // Create and build a window          win := gwu.NewWindow("main", "Test GUI Window")          win.Style().SetFullWidth()          win.SetHAlign(gwu.HA_CENTER)          win.SetCellPadding(2)            // Button which changes window content          win.Add(gwu.NewLabel("I'm a label! Try clicking on the button=>"))          btn := gwu.NewButton("Click me")          btn.AddEHandler(&MyButtonHandler{text: ":-)"}, gwu.ETYPE_CLICK)          win.Add(btn)          btnsPanel := gwu.NewNaturalPanel()          btn.AddEHandlerFunc(func(e gwu.Event) {                  // Create and add a new button...                  newbtn := gwu.NewButton("Extra #" + strconv.Itoa(btnsPanel.CompsCount()))                  newbtn.AddEHandlerFunc(func(e gwu.Event) {                          btnsPanel.Remove(newbtn) // ...which removes itself when clicked                          e.MarkDirty(btnsPanel)                  }, gwu.ETYPE_CLICK)                  btnsPanel.Insert(newbtn, 0)                  e.MarkDirty(btnsPanel)          }, gwu.ETYPE_CLICK)          win.Add(btnsPanel)            // ListBox examples          p := gwu.NewHorizontalPanel()          p.Style().SetBorder2(1, gwu.BRD_STYLE_SOLID, gwu.CLR_BLACK)          p.SetCellPadding(2)          p.Add(gwu.NewLabel("A drop-down list being"))          widelb := gwu.NewListBox([]string{"50", "100", "150", "200", "250"})          widelb.Style().SetWidth("50")          widelb.AddEHandlerFunc(func(e gwu.Event) {                  widelb.Style().SetWidth(widelb.SelectedValue() + "px")                  e.MarkDirty(widelb)          }, gwu.ETYPE_CHANGE)          p.Add(widelb)          p.Add(gwu.NewLabel("pixel wide. And a multi-select list:"))          listBox := gwu.NewListBox([]string{"First", "Second", "Third", "Forth", "Fifth", "Sixth"})          listBox.SetMulti(true)          listBox.SetRows(4)          p.Add(listBox)          countLabel := gwu.NewLabel("Selected count: 0")          listBox.AddEHandlerFunc(func(e gwu.Event) {                  countLabel.SetText("Selected count: " + strconv.Itoa(len(listBox.SelectedIndices())))                  e.MarkDirty(countLabel)          }, gwu.ETYPE_CHANGE)          p.Add(countLabel)          win.Add(p)            // Self-color changer check box          greencb := gwu.NewCheckBox("I'm a check box. When checked, I'm green!")          greencb.AddEHandlerFunc(func(e gwu.Event) {                  if greencb.State() {                          greencb.Style().SetBackground(gwu.CLR_GREEN)                  } else {                          greencb.Style().SetBackground("")                  }                  e.MarkDirty(greencb)          }, gwu.ETYPE_CLICK)          win.Add(greencb)            // TextBox with echo          p = gwu.NewHorizontalPanel()          p.Add(gwu.NewLabel("Enter your name:"))          tb := gwu.NewTextBox("")          tb.AddSyncOnETypes(gwu.ETYPE_KEY_UP)          p.Add(tb)          p.Add(gwu.NewLabel("You entered:"))          nameLabel := gwu.NewLabel("")          nameLabel.Style().SetColor(gwu.CLR_RED)          tb.AddEHandlerFunc(func(e gwu.Event) {                  nameLabel.SetText(tb.Text())                  e.MarkDirty(nameLabel)          }, gwu.ETYPE_CHANGE, gwu.ETYPE_KEY_UP)          p.Add(nameLabel)          win.Add(p)            // Create and start a GUI server (omitting error check)          server := gwu.NewServer("guitest", "localhost:8081")          server.SetText("Test GUI App")          server.AddWin(win)          server.Start("") // Also opens windows list in browser  }

结果如下:
