GoVCL
Cross-platform Golang GUI library, The core binding is liblcl, a common cross-platform GUI library created by Lazarus.
GoVCL is a native GUI library, not based on HTML, let alone DirectUI library, everything is practical.
Full name: Go Language Visual Component Library
govcl minimum requirement is go1.9.2.

Support Platform
Windows | Linux | macOS
If you want to support linux arm and linux 32bit, you need to compile the corresponding liblcl binary.
Pre-compiled GUI library binary download (source code)
res2go IDE plugin source code(source code)
How to use: Installation method
Note: Designed in Lazarus, code written in Golang.
usage:
Step 1: Get the govcl code
go get -u github.com/ying32/govcl
Note: You can also use go module mode, configure in go.mod, such as: github.com/ying32/govcl v2.2.0+incompatible
.
Step 2: Write the code
- Method 1(Use Lazarus to design the GUI. recommend):
package main import ( // Do not reference this package if you use custom syso files _ "github.com/ying32/govcl/pkgs/winappres" "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) vcl.Application.CreateForm(&aboutForm) vcl.Application.Run() } // -- TMainForm func (f *TMainForm) OnFormCreate(sender vcl.IObject) { } func (f *TMainForm) OnBtn1Click(sender vcl.IObject) { aboutForm.Show() } // -- TAboutForm func (f *TAboutForm) OnFormCreate(sender vcl.IObject) { } func (f *TAboutForm) OnBtn1Click(sender vcl.IObject) { vcl.ShowMessage("Hello!") }
Method 1 needs to be used in conjunction with the res2go tool.
- Method 2(Pure code, imitating the way of FreePascal class):
package main import ( // Do not reference this package if you use custom syso files _ "github.com/ying32/govcl/pkgs/winappres" "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.RunApp(&mainForm, &aboutForm) } // -- TMainForm func (f *TMainForm) OnFormCreate(sender vcl.IObject) { f.SetCaption("MainForm") f.Btn1 = vcl.NewButton(f) f.Btn1.SetParent(f) f.Btn1.SetBounds(10, 10, 88, 28) f.Btn1.SetCaption("Button1") f.Btn1.SetOnClick(f.OnBtn1Click) } func (f *TMainForm) OnBtn1Click(sender vcl.IObject) { aboutForm.Show() } // -- TAboutForm func (f *TAboutForm) OnFormCreate(sender vcl.IObject) { f.SetCaption("About") f.Btn1 = vcl.NewButton(f) //f.Btn1.SetName("Btn1") f.Btn1.SetParent(f) f.Btn1.SetBounds(10, 10, 88, 28) f.Btn1.SetCaption("Button1") f.Btn1.SetOnClick(f.OnBtn1Click) } func (f *TAboutForm) OnBtn1Click(sender vcl.IObject) { vcl.ShowMessage("Hello!") }
Step 3: Copy the corresponding binary
-
Windows: Depending on whether the compiled binary is 32 or 64 bits, copy the corresponding
liblcl.dll
to the current executable file directory or system environment path.- Go environment variable:
GOARCH = amd64 386
GOOS = windows
CGO_ENABLED=0
- Go environment variable:
-
Linux: Copy
liblcl.so
under the current executable file directory (you can also copyliblcl.so
to/usr/lib/
(32bit liblcl) or/usr/lib/x86_64-linux-gnu/
(64bit liblcl) directory , Used as a public library).- Go environment variable:
GOARCH = amd64
GOOS = linux
CGO_ENABLED=1
- Go environment variable:
-
MacOS: Copy
liblcl.dylib
to the current executable file directory (note under MacOS: you need to create info.plist file yourself), or refer to: App packaging on MacOS- Go environment variable:
GOARCH = amd64
GOOS = darwin
CGO_ENABLED=1
- Go environment variable:
Note: The "current executable file directory" here refers to the location of the executable file generated by your currently compiled project.
Special Note: All UI components are non-threaded/non-coroutine safe. When used in goroutine, use vcl.ThreadSync to synchronize updates to the UI.
Special Note 2: If you use go>=1.15 to compile Windows executable files, you must use the -buildmode=exe
compilation option, otherwise there will be errors.
Q: Why is there no English WIKI?
A: My English is bad. You can try using Google Translate Chinese WIKI.
