简介
- gotk3 项目为 GTK 3 和依赖项目提供 Go 绑定。每个组件都有自己的子目录，用作包的导入路径。目前已实现对以下库的部分绑定支持：
- GTK 3（3.12 及更高版本）
- GDK 3（3.12 及更高版本）
- GLib 2（2.36 及更高版本）
环境变量
vim ~/.bash_profile
# 添加 PKG_CONFIG_PATH
export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig/:`brew --prefix gtk+3`/lib/pkgconfig go get -u -v github.com/gotk3/gotk3/gdk:$PKG_CONFIG_PATH"
source ~/.bash_profile
官方示例
git clone https://github.com/gotk3/gotk3-examples.git
# 没有go.mod文件则需要初始化
go mod init example.com/glade
go mod tidy
# gotk3依赖
# go get github.com/gotk3/gotk3/gtk
go run glade.go
demo.glade
