Taskbar icon and popup menu coordinates
My App added icon to the TaskBar by Shell_NotifyIcon and receiving notifycations about mouse events...Now I want to bring up popup menu after right button click. But how should I know proper coordinates for the menu ? How I can obtain coordinates of icon or coordinates of mouse pointer during this event ?
Thanks in advance.
Thanks in advance.
Trof, this is not so trivial as you may think. Due to a bug on certain builds of Win95, you have do something like the following:
LRESULT CALLBACK WindowProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
switch (msg)
{
// Tray icon notification message
case MYWM_NOTIFYICON:
// Button event is single click?
if (lParam == WM_LBUTTONDOWN || lParam == WM_RBUTTONDOWN)
{
POINT pos;
// Show and process menu
// SetForegroundWindow() and PostMessage() used to circumvent a Win95 bug
GetCursorPos(&pos);
SetForegroundWindow(hwnd);
TrackPopupMenuEx(GetSubMen u(GetMenu( hwnd), 0), TPM_HORIZONTAL, pos.x, pos.y, hwnd, NULL);
PostMessage(hwnd, WM_NULL, 0, 0);
}
break;
// Other cases...
default:
return DefWindowProc(hwnd, msg, wParam, lParam);
}
return 0;
}
If you think this constitutes an answer, please say so. Otherwise, ignore me.
LRESULT CALLBACK WindowProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
switch (msg)

{
POINT pos;
// Show and process menu
// SetForegroundWindow() and PostMessage() used to circumvent a Win95 bug
GetCursorPos(&pos);
SetForegroundWindow(hwnd);
TrackPopupMenuEx(GetSubMen
PostMessage(hwnd, WM_NULL, 0, 0);
}
break;

return DefWindowProc(hwnd, msg, wParam, lParam);
}
return 0;
}

Alexo, What kind of bug? Looking to your code I see normal behaviour - nothing that looks like a workaround
What alexo refers to is the following KB article.

They say this "behavior is by design". From now on, that's what I'm going to tell my customers about my bugs.
I'm talking about the two lines surrounding the TrackPopupMenuEx() :
---> SetForegroundWindow(hwnd);
---> PostMessage(hwnd, WM_NULL, 0, 0);
See the KB article (at the URL chensu provided) for details.

Because I found GetCursorPos by myself, but answer from BudVVeezer was here before I posted comment "Sorry for bothering "...
