windows下 go安装qt绑定

原作者: [db:作者] 来自: [db:来源] 收藏 邀请

 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()
}
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

 

 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.
