使用installerbuilder创建一个自定义安装页面 ，包含一个控件 用来输入机构名称 请举例说明

好的，下面是一个使用installerbuilder创建一个自定义安装页面的示例，包含一个控件用来输入机构名称的步骤：

1. 创建一个Qt Widgets应用程序，并将以下代码添加到main.cpp文件中：

#include "mainwindow.h"
#include <QApplication>
#include <QtPlugin>

Q_IMPORT_PLUGIN(QWindowsIntegrationPlugin)

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    MainWindow w;
    w.show();
    return a.exec();
}

2. 创建一个MainWindow类，并在构造函数中添加以下代码：

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QLineEdit>
#include <QVBoxLayout>
#include <QLabel>
#include <QHBoxLayout>
#include <QSpacerItem>
#include <QSizePolicy>

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    QLabel* label = new QLabel("Enter organization name:");
    QLineEdit* lineEdit = new QLineEdit;
    QHBoxLayout* hLayout = new QHBoxLayout;
    hLayout->addWidget(label);
    hLayout->addWidget(lineEdit);
    hLayout->addSpacerItem(new QSpacerItem(40, 20, QSizePolicy::Expanding, QSizePolicy::Minimum));

    QVBoxLayout* vLayout = new QVBoxLayout;
    vLayout->addLayout(hLayout);

    QWidget* widget = new QWidget;
    widget->setLayout(vLayout);
    setCentralWidget(widget);
}

MainWindow::~MainWindow()
{
    delete ui;
}

3. 打开Qt Creator，创建一个新的Qt Installer Framework项目，并将项目文件installer.xml中的以下内容替换为下面的代码：

<?xml version="1.0" encoding="UTF-8"?>
<Installer>
    <Name>MyInstaller</Name>
    <Version>1.0.0</Version>
    <Title>My Installer</Title>
    <Publisher>My Company</Publisher>
    <StartMenuDir>My Company</StartMenuDir>
    <TargetDir>@RootDir@</TargetDir>

    <ResourceFile>resources.qrc</ResourceFile>
    <ControlScript>installscript.qs</ControlScript>

    <WizardDialog>
        <Title>My Installer</Title>
        <SubTitle>Installation</SubTitle>
        <TopImage>:/images/qt_installer_background.png</TopImage>
        <BottomImage>:/images/qt_installer_background.png</BottomImage>
        <AllowBackward>true</AllowBackward>
        <AllowCancel>true</AllowCancel>
        <AllowSkip>true</AllowSkip>
        <Default>true</Default>
        <IntroPage>
            <Title>Welcome</Title>
            <SubTitle>Install My Application</SubTitle>
            <Text>Welcome to the installation of My Application.</Text>
        </IntroPage>
        <ComponentPage>
            <Title>Components</Title>
            <SubTitle>Select the components to install.</SubTitle>
            <Text>Select the components you want to install.</Text>
            <Component>
                <Name>Default</Name>
                <DisplayName>Default</DisplayName>
                <Description>The default components.</Description>
                <Checkable>true</Checkable>
                <Checked>true</Checked>
            </Component>
        </ComponentPage>
        <LicenseAgreementPage>
            <Title>License Agreement</Title>
            <SubTitle>Read the following license agreement.</SubTitle>
            <Text>Please read the following license agreement before installing My Application.</Text>
            <LicenseFile>license.txt</LicenseFile>
            <CheckBoxText>I accept the terms of the license agreement.</CheckBoxText>
        </LicenseAgreementPage>
        <TargetDirectoryPage>
            <Title>Installation Folder</Title>
            <SubTitle>Choose the folder to install My Application.</SubTitle>
            <Text>Please choose the folder where you want to install My Application.</Text>
            <TargetDirectory>@RootDir@/MyApplication</TargetDirectory>
            <AllowNonEmptyDirectory>false</AllowNonEmptyDirectory>
        </TargetDirectoryPage>
        <InstallationPage>
            <Title>Installation</Title>
            <SubTitle>Installing My Application</SubTitle>
            <Text>Installing My Application...</Text>
            <ProgressMinimum>0</ProgressMinimum>
            <ProgressMaximum>0</ProgressMaximum>
            <ProgressBarText>Installing...</ProgressBarText>
        </InstallationPage>
        <FinishedPage>
            <Title>Installation Complete</Title>
            <SubTitle>My Application has been successfully installed.</SubTitle>
            <Text>My Application has been successfully installed.</Text>
            <RunProgram>MyApplication.exe</RunProgram>
            <RunProgramArguments>-style fusion</RunProgramArguments>
            <AllowCancel>false</AllowCancel>
            <LaunchProgram>false</LaunchProgram>
        </FinishedPage>
    </WizardDialog>
    
    <InstallerWindow>
        <Width>500</Width>
        <Height>400</Height>
        <Title>My Installer</Title>
        <Watermark>:/images/qt_installer_background.png</Watermark>
        <Logo>:/images/qt_installer_logo.png</Logo>
        <Text>My Installer</Text>
    </InstallerWindow>
    
    <Page>
        <Name>MyCustomPage</Name>
        <Title>My Custom Page</Title>
        <SubTitle>Enter organization name</SubTitle>
        <Widget>
            <Name>MyCustomWidget</Name>
            <Type>QWidget</Type>
            <StyleSheet>background-color: white;</StyleSheet>
            <Layout>
                <Spacing>6</Spacing>
                <Margin>11, 11, 11, 11</Margin>
                <Item>
                    <Widget>
                        <Name>MyCustomLineEdit</Name>
                        <Type>QLineEdit</Type>
                        <StyleSheet></StyleSheet>
                        <SizePolicy>
                            <VerticalPolicy>Fixed</VerticalPolicy>
                            <HorizontalPolicy>Expanding</HorizontalPolicy>
                        </SizePolicy>
                    </Widget>
                </Item>
            </Layout>
        </Widget>
    </Page>
</Installer>

4. 创建一个新的Qt Widgets应用程序，将MainWindow类的代码复制到新应用程序的MainWindow类中。

5. 打开installscript.qs文件，将以下代码添加到文件末尾：

function MyCustomPage()
{
    var widget = gui.currentPageWidget();
    widget.MyCustomLineEdit.text = "";
    widget.MyCustomLineEdit.textChanged.connect(function() {
        installer.setValue("OrganizationName", widget.MyCustomLineEdit.text);
    });
}

function Controller()
{
    installer.installationFinished.connect(function() {
        var organizationName = installer.value("OrganizationName");
        if (organizationName != "") {
            var settingsFile = installer.value("TargetDir") + "/MyApplication/settings.ini";
            var settings = new QSettings(settingsFile, QSettings.IniFormat);
            settings.setValue("OrganizationName", organizationName);
        }
    });
}

6. 在Qt Creator中打开resources.qrc文件，添加以下代码：

<RCC>
    <qresource prefix="/">
        <file>qt_installer_background.png</file>
        <file>qt_installer_logo.png</file>
    </qresource>
</RCC>

7. 在Qt Creator中打开项目文件installer.xml，单击右键，选择“构建”以构建安装程序。

8. 运行安装程序并检查自定义页面是否包含一个控件以输入机构名称。在安装完成后，该机构名称将被保存在安装目录下的settings.ini文件中。
