1.下载安装QT
离线版QT地址: https://download.qt.io/official_releases/qt/5.11/5.11.1/qt-opensource-windows-x86-5.11.1.exe
注意：
最好全部安装，否则在后续的安装过程中会提示相应的文件找不到
2. 在环境变量中指定QT_DIR
默认的QT_DIR为C:\Qt
如果不指定QT_DIR，在后续安装过程中会出现如下错误
3. 将g++所在路径加入环境变量PATH中
C:\Qt\Qt5.11.1\Tools\mingw530_32\bin C:\Qt\Qt5.11.1\5.11.1\mingw53_32\bin C:\Qt\Qt5.11.1\Tools\mingw530_32\opt\bin
C:\Qt\Qt5.11.1\Tools\mingw530_32\bin 目录下包含了gcc、g++等编译链接工具
C:\Qt\Qt5.11.1\5.11.1\mingw53_32\bin 目录下包含了qmake.exe以及程序运行过程中需要的动态链接库(.dll)文件
4. 安装go
下载地址: https://golang.org/dl/
5. 下载安装therecipe/qt
# 下载 go get -v github.com/therecipe/qt/cmd/... # 安装 %GOPATH%\bin\qtsetup.exe
安装过程中出现的硬链接失败可以忽略
生成的静态库所在路径为: %GOPATH%\pkg\windows_386\github.com\therecipe\qt
总共预计安装39个静态库文件(后缀名为.a)。其中安装成功38个，安装失败1个（winextras）。
安装记录如下:

运行的测试代码所在目录源码目录(therecipe\qt)下的的internal\examples目录下。
6. 简单的程序
目录结构：
代码:
package main import ( "os" "github.com/therecipe/qt/widgets" "github.com/therecipe/qt/gui" "github.com/therecipe/qt/core" ) func main() { // 创建应用程序 app := widgets.NewQApplication(len(os.Args), os.Args) // 创建主窗口 window := widgets.NewQWidget(nil, 0) // 设置窗口最小尺寸 window.SetMinimumSize2(400, 200) // 设置标题 window.SetWindowTitle("hello QT, hello GO") mainLayout := widgets.NewQVBoxLayout() // 创建垂直布局 window.SetLayout(mainLayout) lineEidt := widgets.NewQLineEdit(nil) //创建一个label，用于存放go logo icon := gui.NewQPixmap5("go.jpg", "", core.Qt__AutoColor) iconLabel := widgets.NewQLabel(nil, 0) iconLabel.SetPixmap(icon) btn := widgets.NewQPushButton2("点我", nil) btn.ConnectClicked(func(bool) { widgets.QMessageBox_Information(nil, "我是对话框", "hello go，hello qt", widgets.QMessageBox__Ok, widgets.QMessageBox__Ok) }) // !!!! 注意是AddWidget 不是AddChildWidget mainLayout.AddWidget(lineEidt, 0, 0) mainLayout.AddWidget(iconLabel, 0, 0) window.Layout().AddWidget(btn) // 显示窗口 window.Show() // 进入消息循环 app.Exec() }
生成目标exe文件
F:\Workspace\go\src\gui\qt>qtdeploy build desktop hello
需要将go.jpg拷贝至hello\deploy\windows\目录下(与hello.exe处于一个目录下)方可正常运行。
运行效果：
遇到的问题:
1) "xxx/src/github.com/therecipe/qt/gui" has no buildable Go source files
解决方法:
点击 Help > Edit Custom Properties
#添加如下内容 idea.max.intellisense.filesize=99999
由于静态库gui.a很大，因此需要提高goland智能补全所允许的 单个文件大小上限
2) 运行时内存不足
解决方法:
点击Goland 的开始菜单 Help > Edit Custom VM Options
根据配置 修改-Xmx选项，例如:
-Xms512m -Xmx4096m -XX:ReservedCodeCacheSize=480m -XX:+UseConcMarkSweepGC -XX:SoftRefLRUPolicyMSPerMB=50 -ea -Dsun.io.useCanonCaches=false -Djava.net.preferIPv4Stack=true -XX:+HeapDumpOnOutOfMemoryError -XX:-OmitStackTraceInFastThrow
-Xmx value limits the maximum heap memory size that the JVM can allocate.
