Apache-2.0

一个跨平台的Golang GUI库,底层绑定自Delphi VCL和Lazarus LCL


从1.2.0版本开始govcl将最低要求go1.9。


license Minimum Go version screenshots Chinese Wiki Chinese Chat Update log

Support Platform
注: linux和macOS由于底层使用了lcl库,则部分组件、属性和方法无效。

如果你想要支持linux arm及linux 32bit则需要自己编译对应的liblcl二进制。

预编译GUI库二进制下载:
Librarys
注:压缩包内包含的“libvcl”库二进制(libvcl.dll、libvclx64.dll)仅供预览和测试使用。正式使用请自行编译“libvcl”源代码,具体编译方法参考UILIbSrcources中的说明。

res2go工具下载
res2go
注:用Delphi/Lazarus设计界面,用Golang写代码。


使用方法

go get github.com/ying32/govcl

  • 方法一:
package main

import (
   "github.com/ying32/govcl/vcl"
)

func main() {
    vcl.Application.Initialize()
    mainForm := vcl.Application.CreateForm()
    mainForm.SetCaption("Hello")
    mainForm.EnabledMaximize(false)
    mainForm.ScreenCenter()
    btn := vcl.NewButton(mainForm)
    btn.SetParent(mainForm)
    btn.SetCaption("Hello")
    btn.SetOnClick(func(sender vcl.IObject) {
        vcl.ShowMessage("Hello!")
    })
    vcl.Application.Run()
}
  • 方法二:
package main


import (
   "github.com/ying32/govcl/vcl"
)

type TMainForm struct {
    *vcl.TForm
    Btn1     *vcl.TButton
}

type TAboutForm struct {
    *vcl.TForm
    Btn1    *vcl.TButton
}

var (
    mainForm *TMainForm
    aboutForm *TAboutForm
)

func main() {
    vcl.Application.Initialize()
    vcl.Application.SetMainFormOnTaskBar(true)
    vcl.Application.CreateForm(&mainForm)
    // 创建完后关联子组件事件
    vcl.Application.CreateForm(&aboutForm, true)
    vcl.Application.Run()
}

// -- TMainForm

func (f *TMainForm) OnFormCreate(sender vcl.IObject) {
    f.SetCaption("Hello")
    f.Btn1 = vcl.NewButton(f)
    f.Btn1.SetParent(f)
    f.Btn1.SetBounds(10, 10, 88, 28)
    f.Btn1.SetCaption("Button1")
    f.Btn1.SetOnClick(f.OnButtonClick)  
}

func (f *TMainForm) OnButtonClick(sender vcl.IObject) {
    vcl.ShowMessage("Hello!")
}


// -- TAboutForm

func (f *TAboutForm) OnFormCreate(sender vcl.IObject) {
    f.SetCaption("Hello")
    f.Btn1 = vcl.NewButton(f)
    //f.Btn1.SetName("Btn1")
    f.Btn1.SetParent(f)
    f.Btn1.SetBounds(10, 10, 88, 28)
    f.Btn1.SetCaption("Button1")
}

func (f *TAboutForm) OnBtn1Click(sender vcl.IObject) {
    vcl.ShowMessage("Hello!")
}
  • 方法三:
package main


import (
   "github.com/ying32/govcl/vcl"
)

type TMainForm struct {
    *vcl.TForm
    Btn1     *vcl.TButton
}

type TAboutForm struct {
    *vcl.TForm
    Btn1    *vcl.TButton
}

var (
    mainForm *TMainForm
    aboutForm *TAboutForm
)

func main() {
    vcl.Application.Initialize()
    vcl.Application.SetMainFormOnTaskBar(true)
    vcl.Application.CreateForm(mainFormBytes, &mainForm)
    vcl.Application.CreateForm("./about.gfm", &aboutForm)
    vcl.Application.Run()
}

// -- TMainForm

func (f *TMainForm) OnFormCreate(sender vcl.IObject) {
    
}

func (f *TMainForm) OnBtn1Click(sender vcl.IObject) {
    vcl.ShowMessage("Hello!")
}

// -- TAboutForm

func (f *TAboutForm) OnFormCreate(sender vcl.IObject) {
 
}

func (f *TAboutForm) OnBtn1Click(sender vcl.IObject) {
    vcl.ShowMessage("Hello!")
}

方法三需要配合UI设计器或者res2go工具使用。


注意:

当使用"liblcl"库时,是以兼容"libvcl"库形式运行的,所以有部分组件和组件的方法、属性及事件不可用。
