windows下 go安装qt绑定

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.\mingw53_32\bin
C:\Qt\Qt5.11.1\Tools\mingw530_32\opt\bin

windows下 go安装qt绑定

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:

windows下 go安装qt绑定

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, )
// 设置窗口最小尺寸
window.SetMinimumSize2(, )
// 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, )
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, , )
mainLayout.AddWidget(iconLabel, , )
window.Layout().AddWidget(btn) // 显示窗口
window.Show()
// 进入消息循环
app.Exec()
}

main.go

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

windows下 go安装qt绑定

 解决方法:

点击 Help > Edit Custom Properties

windows下 go安装qt绑定

#添加如下内容
idea.max.intellisense.filesize=

windows下 go安装qt绑定

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

windows下 go安装qt绑定

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=
-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.
