Shifting Focus while Tabbing in a toolbar

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.

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

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
