SetWindowPos has not effect on tooltip
- by YoungPony
Hello,
I am trying to give my ComboBox an in place tooltip for long strings. However when I call SetWindowPos on the tooltip, the position is never changed. Called when TTN_SHOW is received:
::SetWindowPos(textTooltip, NULL, TipRect.left, TipRect.top, 0, 0, SWP_NOSIZE | SWP_NOACTIVATE | SWP_NOZORDER);
If I remove the SWP_NOSIZE flag and pop in some values into the width/height, then the combo box changes size to these values but the position remains the same. SetWindowPos always returns TRUE.
The tip is initialised like so:
textTooltip = CreateWindowEx(WS_EX_TRANSPARENT, TOOLTIPS_CLASS, NULL, TTS_NOPREFIX, 0, 0, 0, 0, this->GetSafeHwnd(), NULL, NULL, NULL);
if(!textTooltip)
return;
ZeroMemory(&ToolInfo, sizeof(TOOLINFO));
ToolInfo.cbSize = sizeof(TOOLINFO);
ToolInfo.uFlags = TTF_TRANSPARENT | TTF_SUBCLASS;
ToolInfo.hwnd = this->GetSafeHwnd();
ToolInfo.lpszText = "place holder"; //set in OnSelectChangeOk
ToolInfo.uId = 0;
ToolInfo.rect = TipRect; //rect is re-set in OnSelectChangeOk
::SendMessage(textTooltip, TTM_ADDTOOL, 0, (LPARAM)&ToolInfo);
Am I missing something?
