Question

我正在编写一个Bootstrapper应用程序，并希望使用WixStandardBootstrapperApplication为它创建UI。我想要UI，这样在第一页（安装页面）上，我看到标准的EULA和一个复选框，表示我接受，一个按钮继续下一页（选项页面），只有在我选中复选框后才能启用。在下一页，我列出了一些文本，并希望有另一个复选框，再次说我接受了，还有一个安装按钮，只有在我选中复选框后才能启用。

<Page Name="Install">
  <Text X="154" Y="12" Width="-65" Height="21" DisablePrefix="yes">#(loc.Title)</Text>
  <Image X="120" Y="20" Width="54" Height="325" ImageFile="logo.png"/>
  <Richedit Name="EulaRichedit" X="154" Y="60" Width="-21" Height="-76" TabStop="yes" FontId="0" HexStyle="0x800000" />
  <Checkbox Name="OptionsCheckbox" X="-11" Y="-41" Width="246" Height="17" TabStop="yes" FontId="3" HideWhenDisabled="yes">I accept.</Checkbox>
  <Button Name="WelcomeCancelButton" X="-11" Y="-11" Width="75" Height="23" TabStop="yes" FontId="0">#(loc.InstallCloseButton)</Button>
  <Button Name="OptionsButton" X="-91" Y="-11" Width="75" Height="23" TabStop="yes" FontId="0" Text="Proceed" HideWhenDisabled="yes">Next</Button>
</Page>
<Page Name="Options">
  <Text X="185" Y="11" Width="-11" Height="32" FontId="1">#(loc.OptionsHeader)</Text>
  <Image X="0" Y="0" Width="177" Height="325" ImageFile="logoside.png"/>
  <Text X="180" Y="61" Width="-11" Height="17" FontId="3">Some text.</Text>
  <Checkbox Name="EulaAcceptCheckbox" X="180" Y="251" Width="246" Height="17" TabStop="yes" FontId="3" HideWhenDisabled="yes">#(loc.OptionsButton)</Checkbox>
  <Button Name="InstallButton" X="-91" Y="-11" Width="75" Height="23" TabStop="yes" FontId="0" Text="Proceed">#(loc.InstallInstallButton)</Button>
  <Button Name="OptionsCancelButton" X="-11" Y="-11" Width="75" Height="23" TabStop="yes" FontId="0">#(loc.InstallCloseButton)</Button>
</Page>

第二页（选项页面）根据我的需要工作 - 禁用复选框和安装按钮，只有在选中复选框后才会启用它。但是在第一页（安装页面）上我无法使其正常工作。即使未选中该复选框，也会启用该按钮。我为Checkbox和Button Name尝试了不同的选项，但我无法使其工作。我能做些什么才能让它发挥作用？此外，如果您有任何关于不同选项的文档的链接，请分享。我找到了Thmutil模式的帮助文件，但它没有列出复选框或按钮的各种选项。

欢迎任何建议。随意询问是否有任何不清楚的地方。感谢您的帮助。

为此，您需要深入研究bootstrapperapplication的代码（WixStdBootstrapperApplication.cpp）。

幸运的是，你的基础是WixStdBootstrapperApplication，我花了很长时间才知道。

您需要做的第一件事就是将EulaAcceptCheckbox放回到页面上，并在其上放置实际的Eula。当您要控制启用/禁用UI元素时，您需要在引导程序应用程序的代码中执行此操作。 BA拥有UI。

现在我们需要更改EulaAcceptCheckbox的行为，以便启用/禁用OptionsButton。

在WndProc中，我们处理用户点击按钮或滚动或执行任何操作时生成的所有消息。在WM_COMMAND下，我们有一个基于LOWORD（wParam）的开关，它是引发消息的控件的ID。

找到“WIXSTDBA_CONTROL_EULA_ACCEPT_CHECKBOX”并看到它调用pBA-＆gt; OnClickAcceptCheckbox（）;

这是方法

void OnClickAcceptCheckbox()
{
    BOOL fAcceptedLicense = ThemeIsControlChecked(m_pTheme, WIXSTDBA_CONTROL_EULA_ACCEPT_CHECKBOX);
    ThemeControlEnable(m_pTheme, WIXSTDBA_CONTROL_INSTALL_BUTTON, fAcceptedLicense);
}

看起来超级简单吧？在这里你只需要将WIXSTDBA_CONTROL_INSTALL_BUTTON更改为WIXSTDBA_CONTROL_OPTIONS_BUTTON

我们还需要将“选项”按钮设置为默认禁用。为此，我们进入“OnChangeState”并查找if for WIXSTDBA_PAGE_INSTALL

if (m_rgdwPageIds[WIXSTDBA_PAGE_INSTALL] == dwNewPageId) // on the "Install" page, ensure the install button is enabled/disabled correctly.
{
    LONGLONG llElevated = 0;
    if (m_Bundle.fPerMachine)
    {
        BalGetNumericVariable(WIXBUNDLE_VARIABLE_ELEVATED, &llElevated);
    }
    ThemeControlElevates(m_pTheme, WIXSTDBA_CONTROL_INSTALL_BUTTON, (m_Bundle.fPerMachine && !llElevated));

    // If the EULA control exists, show it only if a license URL is provided as well.
    if (ThemeControlExists(m_pTheme, WIXSTDBA_CONTROL_EULA_LINK))
    {
        BOOL fEulaLink = (m_sczLicenseUrl && *m_sczLicenseUrl);
        ThemeControlEnable(m_pTheme, WIXSTDBA_CONTROL_EULA_LINK, fEulaLink);
        ThemeControlEnable(m_pTheme, WIXSTDBA_CONTROL_EULA_ACCEPT_CHECKBOX, fEulaLink);
    }

    BOOL fAcceptedLicense = !ThemeControlExists(m_pTheme, WIXSTDBA_CONTROL_EULA_ACCEPT_CHECKBOX) || !ThemeControlEnabled(m_pTheme, WIXSTDBA_CONTROL_EULA_ACCEPT_CHECKBOX) || ThemeIsControlChecked(m_pTheme, WIXSTDBA_CONTROL_EULA_ACCEPT_CHECKBOX);
    ThemeControlEnable(m_pTheme, WIXSTDBA_CONTROL_INSTALL_BUTTON, fAcceptedLicense);

    // If there is an "Options" page, the "Options" button exists, and it hasn't been suppressed, then enable the button.
    BOOL fOptionsEnabled = m_rgdwPageIds[WIXSTDBA_PAGE_OPTIONS] && ThemeControlExists(m_pTheme, WIXSTDBA_CONTROL_OPTIONS_BUTTON) && !m_fSuppressOptionsUI;
    ThemeControlEnable(m_pTheme, WIXSTDBA_CONTROL_OPTIONS_BUTTON, fOptionsEnabled);

    // Show/Hide the version label if it exists.
    if (m_rgdwPageIds[WIXSTDBA_PAGE_OPTIONS] && ThemeControlExists(m_pTheme, WIXSTDBA_CONTROL_VERSION_LABEL) && !m_fShowVersion)
    {
        ThemeShowControl(m_pTheme, WIXSTDBA_CONTROL_VERSION_LABEL, SW_HIDE);
    }
}

我们需要将此块更新为

if (m_rgdwPageIds[WIXSTDBA_PAGE_INSTALL] == dwNewPageId) // on the "Install" page, ensure the install button is enabled/disabled correctly.
{                    
    // If the EULA control exists, show it only if a license URL is provided as well.
    if (ThemeControlExists(m_pTheme, WIXSTDBA_CONTROL_EULA_LINK))
    {
        BOOL fEulaLink = (m_sczLicenseUrl && *m_sczLicenseUrl);
        ThemeControlEnable(m_pTheme, WIXSTDBA_CONTROL_EULA_LINK, fEulaLink);
        ThemeControlEnable(m_pTheme, WIXSTDBA_CONTROL_EULA_ACCEPT_CHECKBOX, fEulaLink);
    }

    BOOL fAcceptedLicense = !ThemeControlExists(m_pTheme, WIXSTDBA_CONTROL_EULA_ACCEPT_CHECKBOX) || !ThemeControlEnabled(m_pTheme, WIXSTDBA_CONTROL_EULA_ACCEPT_CHECKBOX) || ThemeIsControlChecked(m_pTheme, WIXSTDBA_CONTROL_EULA_ACCEPT_CHECKBOX);

    // If there is an "Options" page, the "Options" button exists, and it hasn't been suppressed, then enable the button.
    BOOL fOptionsEnabled = m_rgdwPageIds[WIXSTDBA_PAGE_OPTIONS] && ThemeControlExists(m_pTheme, WIXSTDBA_CONTROL_OPTIONS_BUTTON) && !m_fSuppressOptionsUI;
    ThemeControlEnable(m_pTheme, WIXSTDBA_CONTROL_OPTIONS_BUTTON, fOptionsEnabled & fAcceptedLicense);

    // Show/Hide the version label if it exists.
    if (m_rgdwPageIds[WIXSTDBA_PAGE_OPTIONS] && ThemeControlExists(m_pTheme, WIXSTDBA_CONTROL_VERSION_LABEL) && !m_fShowVersion)
    {
        ThemeShowControl(m_pTheme, WIXSTDBA_CONTROL_VERSION_LABEL, SW_HIDE);
    }
}

这里我们删除了提升的东西，因为它出现在安装按钮上，而是启用/禁用选项按钮，具体取决于它是否在主题中定义以及是否选中了accept复选框。

接下来，您需要添加一种方法来找到新的OptionsPage复选框。

你的cpp文件中应该有一个枚举

enum WIXSTDBA_CONTROL

应将其订购到页面上的控件中。在这里，您需要为新的选项复选框控件添加一个新条目，可能是WIXSTDBA_CONTROL_OPTIONS_CHECKBOX

在这个枚举下面你将有一个二维数组

static THEME_ASSIGN_CONTROL_ID vrgInitControls[] =

您需要在此处添加一个新条目，该条目插入您插入枚举的同一位置。插入的数组项应该如下所示

{ WIXSTDBA_CONTROL_OPTIONS_CEHCKBOX, L"OptionsCheckbox" },  //The string should match the Name of the checkbox in the theme xml.

现在我们需要一种方法来处理来自此Control的消息。返回WndProc并在WM_COMMAND下向交换机添加一个新案例，它应该是

case WIXSTDBA_CONTROL_OPTIONS_CHECKBOX:
    pBA->OnClickOptionsCheckbox();
    return 0;

现在将OnClickOptionsCheckbox方法添加到您的引导程序应用程序中，就像OnClickAcceptCheckbox（）

一样

void OnClickOptionsCheckbox()
{
    BOOL fAccepted = ThemeIsControlChecked(m_pTheme, WIXSTDBA_CONTROL_OPTIONS_CHECKBOX);
    ThemeControlEnable(m_pTheme, WIXSTDBA_CONTROL_INSTALL_BUTTON, fAccepted);
}

最后，我们需要将从OnChangeState WIXSTDBA_PAGE_INSTALL案例中删除的llElevated内容添加到WIXSTDBA_PAGE_OPTIONS，并设置Install按钮的默认状态

else if (m_rgdwPageIds[WIXSTDBA_PAGE_OPTIONS] == dwNewPageId)
{
    HRESULT hr = BalGetStringVariable(WIXSTDBA_VARIABLE_INSTALL_FOLDER, &sczUnformattedText);
    if (SUCCEEDED(hr))
    {
        // If the wix developer is showing a hidden variable in the UI, then obviously they don't care about keeping it safe
        // so don't go down the rabbit hole of making sure that this is securely freed.
        BalFormatString(sczUnformattedText, &sczText);
        ThemeSetTextControl(m_pTheme, WIXSTDBA_CONTROL_FOLDER_EDITBOX, sczText);
    }
}

将改为

else if (m_rgdwPageIds[WIXSTDBA_PAGE_OPTIONS] == dwNewPageId)
{
    LONGLONG llElevated = 0;
    if (m_Bundle.fPerMachine)
    {
        BalGetNumericVariable(WIXBUNDLE_VARIABLE_ELEVATED, &llElevated);
    }
    ThemeControlElevates(m_pTheme, WIXSTDBA_CONTROL_INSTALL_BUTTON, (m_Bundle.fPerMachine && !llElevated));       

    BOOL fAccepted = !ThemeControlExists(m_pTheme, WIXSTDBA_CONTROL_OPTIONS_CHECKBOX) || !ThemeControlEnabled(m_pTheme, WIXSTDBA_CONTROL_OPTIONS_CHECKBOX) || ThemeIsControlChecked(m_pTheme, WIXSTDBA_CONTROL_OPTIONS_CHECKBOX);
    ThemeControlEnable(m_pTheme, WIXSTDBA_CONTROL_INSTALL_BUTTON, fAccepted);

    HRESULT hr = BalGetStringVariable(WIXSTDBA_VARIABLE_INSTALL_FOLDER, &sczUnformattedText);
    if (SUCCEEDED(hr))
    {
        // If the wix developer is showing a hidden variable in the UI, then obviously they don't care about keeping it safe
        // so don't go down the rabbit hole of making sure that this is securely freed.
        BalFormatString(sczUnformattedText, &sczText);
        ThemeSetTextControl(m_pTheme, WIXSTDBA_CONTROL_FOLDER_EDITBOX, sczText);
    }
}

有一些事情我仍然会改变这个实现，但我强烈建议尝试介绍bootstrapper应用程序的功能及其工作原理。

如果您想在安装过程中更改UI的行为，则需要在此处熟悉代码。您可以添加新页面，添加控件，设置变量以及其他一些内容。

如果这看起来像是很多工作（我自己肯定会搞清楚这一点），请考虑一下真的是否需要这种类型的行为超过默认wixstdba主题之一的默认行为。
