Fantastic !

Thank you so much for sharing. Thank you.

With your suggestion, the following statement has solved the problem:

return CXTPCommandBar::OnKeyDown(VK_RETURN);

The mistake I did was that I always returned TRUE.
I am still not sure how you got this idea.

I was having problem with removing the focus from the combo box totally. What I was not able to do.

Thanks again

Shifting Focus while Tabbing in a toolbar : For those out there, I came up...

For those out there, I came up with an ugly hack to get the tabbing towork (the cursor enters an edit box or a dropdown, regardless ofwhether it is inherited from CWnd or CXTPControl) without altering theCode Jock source code. The work-around is not pleasant, but itseems to work. If there is a better solution, I would love tohear it.

1) Because we cannot alter CXTPCommandBar and we cannot use acustom CommandBar, we need to make a new class that inherits fromCXTPToolBar. Call it CToolBarEx or something.

2) When adding the toolbar that needs the tabbing behavior inCMainFrame:: OnCreate, explicitly indicate what toolbar class to use:

CXTPToolBar* pToolbar = (CXTPToolBar*)pCommandBars->Add(�Toolbar�, xtpBarTop, RUNTIME_CLASS(CToolBarEx));

3) In the CToolBar class, override the OnKeyDown(UINTnChar). Take note this is a custom Codejock method and not thestandard OnKeyDown we all know and love.

4) The body of the OnKeyDown should be:


if( nChar == VK_TAB )
{
  int nNum = m_pControls->GetNext(m_nSelected, +1);
  CXTPControl* pCtrl = GetControl(nNum);
  DWORD tag = pCtrl->GetTag();
  if( tag == 42 )
  {
    SetSelected(nNum, TRUE);
    SetFocusedControl(pCtrl);
    return CXTPCommandBar::OnKeyDown(VK_RETURN);
  }    
}

return CXTPToolBar::OnKeyDown(nChar);

The code essentially sets the next control up for focus and calls anextra OnKeyDown, but with VK_ENTER so that all the codejock code willperform like normal.

The �if(tag == 42 )� statement is noteworthy because we want to checkto see if this control requested the tabbing-enter (You might not wantan Enter performed on a button).

5) When making the control set the Tag data to flag it wants tobe a part of the tab-enter inCMainFrame::OnCreateControl(LPCREATECONTROLSTRUCT lpCreateControl).


// ...Next to your
lpCreateControl->pControl = m_pComboUrl;
// ...put 
pCreateControl->pControl->SetTag( 42 );

6) Test it

Will this change be in a future release? If so, what did you do to move the focus?

How do you shift focus along with the selection (highlight) when tabbing through controls (like CControlComboBoxEx)?

I am having trouble getting certain notifications.

Take a look at the Custom Themes Sample. How can you make itenter focus into the "masked" combo box when the user tabs from aprevious control like the "new" box?

The user should be able to start typing without having to hit first.

Thanks.
