The 1.2.0 version begins with govcl with a minimum requirement of go1.9.

Note: linux and macOS only part of the components, properties, events and methods are valid.

If you want to support linux arm and linux 32bit, you need to compile the corresponding liblcl binary.

Librarys binaries

Note: The "libvcl" library binary (libvcl. dll, libvclx64. dll) contained in the compression package is only for preview and test purposes. Please compile the "libvcl" source code for official use. please refer to the instructions in UILIbSrcources.

res2go Tool

Note: Designed in Delphi/Lazarus, code written in Golang.

usage:

go get github.com/ying32/govcl

• Method 1:

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()
}

• Method 2:

package main


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

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

var (
    mainForm *TMainForm
)

func main() {
    vcl.Application.Initialize()
    vcl.Application.SetMainFormOnTaskBar(true)
    vcl.Application.CreateForm(&mainForm)
    vcl.Application.Run()
}


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!")
}

• Method 3:

package main


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

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

var (
    mainForm *TMainForm
)

func main() {
    vcl.Application.Initialize()
    vcl.Application.SetMainFormOnTaskBar(true)
    vcl.Application.CreateForm(mainFormBytes, &mainForm)
    vcl.Application.Run()
}


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

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

Method 3 needs to be used in conjunction with the UI designer or the res2go tool.
