如何使用 Qt 控制将应用程序固定到任务栏的路径

Answer 1

由于我自己一直在努力寻找一种方法来自定义固定到任务栏的应用程序的程序路径，因此我想在这里发布我与 Qt 相关的解决方案。

问题是，我在固定主程序时将启动程序链接到一组程序（启动程序/更新程序、主程序）中。

EventFilterPinnable.h

#pragma once

#include <QAbstractNativeEventFilter>

#include <windows.h>
#include <windowsx.h>
#include <shellapi.h>
#include <propsys.h>
#include <propkey.h>
#include <propvarutil.h>

HRESULT PropertyStoreSetStringValue(IPropertyStore* propertyStore, REFPROPERTYKEY pkey, PCWSTR value)
{
    PROPVARIANT propVariant;
    HRESULT hr = InitPropVariantFromString(value, &propVariant);
    if(SUCCEEDED(hr))
    {
        hr = propertyStore->SetValue(pkey, propVariant);
        PropVariantClear(&propVariant);
    }
    return hr;
}

HRESULT MakeWindowPinnable(HWND hwnd, PCWSTR userModelId, PCWSTR relaunchCommand, PCWSTR relaunchDisplayName, PCWSTR relaunchIcon = NULL)
{
    IPropertyStore* propertyStore;
    HRESULT hr = SHGetPropertyStoreForWindow(hwnd, IID_PPV_ARGS(&propertyStore));
    if(SUCCEEDED(hr))
    {
        PropertyStoreSetStringValue(propertyStore, PKEY_AppUserModel_ID, userModelId);
        PropertyStoreSetStringValue(propertyStore, PKEY_AppUserModel_RelaunchCommand, relaunchCommand);
        PropertyStoreSetStringValue(propertyStore, PKEY_AppUserModel_RelaunchDisplayNameResource, relaunchDisplayName);

        if(relaunchIcon != NULL)
        {
            PropertyStoreSetStringValue(propertyStore, PKEY_AppUserModel_RelaunchIconResource, relaunchIcon);
        }

        propertyStore->Release();
    }
    return hr;
}

void OnCreate(HWND hwnd)
{
    std::wstring sAppId = L"unique.app.id";
    std::wstring sAppRelaunchCommand = L"\"C:\\Program Files\\Path with spaces\\Starter.exe\" -a argument1";
    std::wstring sAppRelaunchDisplayName = L"Name of progam";
    std::wstring sAppRelaunchIcon = L"\"C:\\Program Files\\Path with spaces\\Icon.ico\"";

    MakeWindowPinnable(hwnd, sAppId.c_str(), sAppRelaunchCommand.c_str(), sAppRelaunchDisplayName.c_str(), sAppRelaunchIcon.c_str());
}


class EventFilterPinnable : public QAbstractNativeEventFilter
{
public:
    EventFilterPinnable() {}

    bool nativeEventFilter(const QByteArray& eventType, void* message, long* /*res*/) override
    {
        if(eventType == "windows_generic_MSG") {
            MSG* msg = static_cast<MSG*>(message);
            HWND hwnd = msg->hwnd;

            if (msg->message==WM_CREATE)
            {
                OnCreate(hwnd);
            }
        }
        return false;
    }
};

在 main.cpp 中简单地添加

QApplication app(argc, argv);    
app.installNativeEventFilter(new EventFilterPinnable());
....
app.exec();
