Control path to pinned application to taskbar with Qt - c++

Question

How control path to pinned application to taskbar with Qt

Answer 1

Since I myself have been searching with a lot of effort for a way to customize the program path to an application pinned to the taskbar, I wanted to post here my solution related to Qt.
Problem was, that I link the starter in a set of programs (starter/updater, main) when pinning the main program.
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;
}
};
in main.cpp simply add
QApplication app(argc, argv);
app.installNativeEventFilter(new EventFilterPinnable());
....
app.exec();
