Hi,
I am using CTooltipCtrl class to set tooltips to my controls in a dialog.
The problem is that if a control is disabled, then the tooltip is not shown.

note: I tried to use TTS_ALWAYSTIP when I create the CTooltipCtrl, but it
didn't help.

Yoav.

I have managed to overcome this *sometimes* by using the AddTool() method to
add rectangle of the parent dialogue which coincides with the location of
the control. Having both this and the actual control, gives the tool tip
both when the control is enabled and when it is disabled.

But on some disabled controls it just doesn't seem to work and I haven't yet
worked out why. Any guesses on this would be welcome!

Hi,
I don't see this in my implementation. But I'm using this method:
<http://msdn2.microsoft.com/en-us/library/100e2es9(VS.80).aspx>

ON_NOTIFY_EX( TTN_NEEDTEXT, 0, OnToolTip )
And OnToolTip is always called even if the window is not enabled.

Best, Dan.

I use that method for tool tips in my CView-derived window.

For controls dialogue boxes

I derive a class CTTDialog from CDialog and derive my dialogues from that.

CTTDialog has (i.a.) a protected data member

CToolTipCtrl m_ToolTip;

and a member function

CString ToolTipText( int nID ) const;

which it uses to get the tool tip text for the control with nID via a
virtual mechanism from the derived class.

In CTTDialog::OnInitDialog() I essentially do:

//====

if( m_ToolTip.Create( this, TTS_ALWAYSTIP ) )
{
m_ToolTip.SetMaxTipWidth( SHRT_MAX );
m_ToolTip.SetDelayTime( TTDT_AUTOPOP, SHRT_MAX );
m_ToolTip.SetDelayTime( TTDT_INITIAL, 500 );
m_ToolTip.SetDelayTime( TTDT_RESHOW, 500 );
m_ToolTip.Activate( m_bShowToolTips );
// Now add the controls as tools:
CString strToolTip;
CWnd *pWndChild = GetWindow(GW_CHILD);

while( pWndChild )
{
int nID = pWndChild->GetDlgCtrlID();
strToolTip = ToolTipText( nID );
CRect rect;
pWndChild->GetWindowRect( &rect );
ScreenToClient( &rect );

// Add a tool which is the actual control AND a pseudo-tool
// which is the area it occupies on the actual dialogue. The
// latter is important when the control is disabled, and gives
// the full functionality for static controls - even ones
// with id=IDC_STATIC.

if( !strToolTip.IsEmpty() )
{
m_ToolTip.AddTool( pWndChild, (LPCTSTR)strToolTip );
m_ToolTip.AddTool( this, (LPCTSTR)strToolTip, &rect, nID );
}

pWndChild = pWndChild->GetWindow(GW_HWNDNEXT);
}
}
//===========

As I say it works most of the time.

Hi David,
For kicks, I pasted your code into a dialog and just used a "this is a
test" for the tip. I get TRUE returned for both AddTool calls for all
the controls. For some reason I don't get any tips?!

What I've done is add a class to dialogs that I want extended tips in.

CTipData tipData;

Then it is just a two liner:
In init:
tipData.Open( _T("RptDirectiveData") );

And:
BOOL CReportSectionDirective::OnToolTip(
UINT id, NMHDR * pNMHDR, LRESULT * pResult )
{
return tipData.DisplayTipText( pNMHDR );
}

Best, Dan.
