unreal engine 给游戏创建托盘图标，右键菜单
plugin
https://github.com/ue4plugins/WindowsMessageHandlerExample
关闭editor，解压后新建一个Plugins文件夹，放到 /Plugins 文件夹
然后打开***.sln，build
右键uproject，generate project fils
再打开editor，Enable plugin ,可以在Output看到已经在运行了;
重新打开vs，可以看到plugin的代码，WindowsMessageHandlerExampleModule.cpp
修改plugin代码
创建一个托盘
class FExampleHandler
icon在package之后的主目录
#if PLATFORM_WINDOWS
#include "Windows/MinWindows.h"
#include
#include
#endif
NOTIFYICONDATA m_nfData;
#define NOTIFY_SHOW WM_USER+2500
#define IDR_MAINFRAME WM_USER +2501
bool CreateIco()
{
HWND hWnd = GetActiveWindow();
m_nfData.hWnd = hWnd;
// 图标路径是package之后的目录，打包完把图标放到启动程序同一个文件夹
const FString pathLaunch = FPaths::LaunchDir() + "icon.ico";
UE_LOG(LogTemp, Warning, TEXT(">>> FPATHS : %s"), *pathLaunch);
HINSTANCE hInst = NULL;
HICON hIcon = (HICON)LoadImage(hInst, *(pathLaunch), IMAGE_ICON, 32, 32, LR_DEFAULTCOLOR | LR_CREATEDIBSECTION | LR_LOADFROMFILE);
const uint32 Error = GetLastError();
GLog->Logf(TEXT("%d"), Error);
m_nfData.cbSize = sizeof(NOTIFYICONDATA);
m_nfData.uID = IDR_MAINFRAME;
m_nfData.hIcon = hIcon;
m_nfData.hWnd = hWnd;
m_nfData.uCallbackMessage = NOTIFY_SHOW;
m_nfData.uVersion = NOTIFYICON_VERSION;
m_nfData.uFlags = NIF_MESSAGE | NIF_ICON | NIF_TIP | NIF_INFO;
lstrcpy(m_nfData.szTip, L"托盘"); //szAppClassName
UE_LOG(LogTemp, Warning, TEXT(">>> Shell_NotifyIcon : "));
return Shell_NotifyIcon(NIM_ADD, &m_nfData);
}
移除托盘
class FExampleHandler
bool DeleteIco()
{
return Shell_NotifyIcon(NIM_DELETE, &m_nfData);
}
给托盘加菜单
// 添加菜单
void AddTrayMenu(HWND Hwnd)
{
POINT pt;
GetCursorPos(&pt);
HMENU menu = CreatePopupMenu();
// quit
AppendMenu(menu, MF_STRING, WM_DESTROY, L"quit");
::SetForegroundWindow(Hwnd);
int32 MenuID = TrackPopupMenu(menu, TPM_RETURNCMD | TPM_LEFTALIGN | TPM_LEFTBUTTON, pt.x, pt.y, NULL, Hwnd, NULL);
GLog->Logf(TEXT("%d"), MenuID);
if (MenuID == WM_DESTROY)
{
UE_LOG(LogTemp, Warning, TEXT(">>> WM_DESTROY : "));
// 退出
RequestEngineExit("exit");
}
DestroyMenu(menu);
}
处理Message
virtual bool ProcessMessage(HWND Hwnd, uint32 Message, WPARAM WParam, LPARAM LParam, int32& OutResult) override
{
// log out some details for the received message
GLog->Logf(TEXT("WindowsMessageHandlerExampleModule: hwnd = %i, msg = %s, wParam = %i, lParam = %i"), Hwnd, *GetMessageName(Message), WParam, LParam);
switch (Message)
{
case NOTIFY_SHOW:
{
switch (LParam)
{
// 右键弹出菜单
case WM_RBUTTONUP:
AddTrayMenu(Hwnd);
break;
}
}
return false;
}
};
package
打包完，把图标放到启动程序目录
