Thread: Toolbar Tooltips not displaying

I created a toolbar, and now I want tooltips to display when the mouse hovers over the buttons. I thought the following code should work:

Code:

m_hTool = CreateWindowEx(0,TOOLBARCLASSNAME, 0, WS_CHILD | TBSTYLE_TOOLTIPS | TBSTYLE_FLAT,
            0,0,0,0,m_hwnd,(HMENU)IDC_MAIN_TOOL,m_hinst,0);

if(!m_hTool)
{
  MessageBox(NULL,"Failed to create toolbar!","Error!",MB_OK);
  return false;
}

SendMessage(m_hTool, TB_BUTTONSTRUCTSIZE,(WPARAM) sizeof(TBBUTTON), 0);
SendMessage(m_hTool, TB_SETMAXTEXTROWS,0,0);

TBBUTTON tbb[NUM_TOOL_BUTTONS];
ZeroMemory(tbb, sizeof(tbb));
for (int i=0;i<NUM_TOOL_BUTTONS;i++)
{
  tbb[i].iBitmap = i;
  tbb[i].fsState = TBSTATE_ENABLED;
  tbb[i].fsStyle = BTNS_BUTTON;
  tbb[i].idCommand = TOOL_BTN_ID[i];
  tbb[i].iString = SendMessage(m_hTool, TB_ADDSTRING, 0, (LPARAM) "Text");
}

TBADDBITMAP tb;
tb.hInst = m_hinst;
tb.nID = IDB_BITMAP2;

SendMessage (m_hTool, TB_ADDBITMAP, 2, (LPARAM)&tb);
SendMessage(m_hTool, TB_ADDBUTTONS, (WPARAM)2, (LPARAM) (LPTBBUTTON) &tbb);

SendMessage(m_hTool, TB_AUTOSIZE, 0, 0);
ShowWindow(m_hTool, SW_SHOWNORMAL);

The buttons/bitmaps display fine, but there's no tooltip. If I don't send TB_SETMAXTEXTROWS then the text displays in the button. Hopefullly I'm just doing something stupid again

I still haven't solved this, but I did find out that no matter what I do, the parent window never receives a TTN_GETDISPINFO message (and it should receive one shouldn't it?) It does, however receive messages (such as TBN_HOTITEMCHANGE) from the toolbar.

I finally traced my error back all the way to my windows message loop. Just one part of a line cause all my problems I had:

Code:

 while(GetMessage(&msg, m_hwnd, 0, 0) > 0)
	{
		if (!TranslateMDISysAccel(m_hwndMDIClient, &msg))
		{
			TranslateMessage(&msg);
			DispatchMessage(&msg);
		}
	}

Instead of:

Code:

 while(GetMessage(&msg, 0, 0, 0) > 0)
	{
		if (!TranslateMDISysAccel(m_hwndMDIClient, &msg))
		{
			TranslateMessage(&msg);
			DispatchMessage(&msg);
		}
	}
