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 it enter focus into the "masked" combo box when the user tabs from a previous control like the "new" box?

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

Thanks.

Thank you for this good suggestion. We changed this behaviour.

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

It is added for 9.70 release. Key handled in CXTPCommandBar::OnKeyDown.

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

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

2) When adding the toolbar that needs the tabbing behavior in CMainFrame:: 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(UINT nChar). Take note this is a custom Codejock method and not the standard 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 an extra OnKeyDown, but with VK_ENTER so that all the codejock code will perform like normal.

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

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



// ...Next to your

lpCreateControl->pControl = m_pComboUrl;

// ...put 

pCreateControl->pControl->SetTag( 42 );

6) Test it

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
