Problem customising a CMFCToolBar

Hi all,

I've followed all the instructions I can find online on how to customise a toolbar by calling CMFCToolBar::ReplaceButton(), and have got it to display a CMFCToolBarComboBoxButton.

I have subclassed CMFCToolBarComboBoxButton in order to override CreateCombo(), but if I call CMFCToolBar::ReplaceButton() with this derived class, my derived CreateCombo() is never being called.

Any ideas what I am doing wrong?

TIA.

PS - This project was converted from VS2005 to VS2010, if that makes any difference.

Where (what method) do you call Replace Button.

It should be done in the handler of AFX_WM_RESETTOOLBAR in the main frame.

this is what I do:
...
ON_REGISTERED_MESSAGE(AFX_WM_RESETTOOLBAR, OnToolbarReset)
...

C++

LRESULT CMainFrame::OnToolbarReset(WPARAM wp,LPARAM)
{
 UINT uiToolBarId = (UINT) wp;
 TRACE( "CMainFrame::OnToolbarReset : %i\n", uiToolBarId );

 switch (uiToolBarId)
 {
  case YOUR_TOOLBAR_ID:
    CMFCToolBarComboBoxButton deviceCombo(IDC_DEVICE_TOOLBAR_COMBO, GetCmdMgr()->GetCmdImage(IDC_DEVICE_TOOLBAR_COMBO, FALSE), CBS_DROPDOWNLIST);
    m_DeviceToolBar.ReplaceButton ( IDC_DEVICE_TOOLBAR_COMBO, deviceCombo   );

  break;
 }
}

NOTE: the framework will save/load the state of the buttons of the toolbars in the registry, if you make changes to the code, the application will still use those values. so remove your application entry in the registry when (re)coding toolbars. This is quite aggravating.

Good luck.

That's what I do, but with a derived button, as described here. If I get a pointer to this replaced button via CMFCToolBar::GetCommandButtons(), I get a pointer to a CMFCToolBarComboBoxButton, not to my derived class. I deleted the Registry entries so that they were regenerated with the new class.

I am working on this same thing. How does one locate the registry entry?

Have you tried deleting the corresponding Registry data for your program? Sometimes changes to the UI don't show up if you change something without deleting the Registry data, as Maximilien said above.

// I get a pointer to a CMFCToolBarComboBoxButton, not to my derived class

Just place DECLARE_DYNCREATE(CYourButton) into its declaration :)

That's got it! Thanks Eugen! :D

Yes. forgot about that.

just a brain freeze question, is it IMPLEMENT/DECLARE_DYNCREATE or IMPLEMENT/DECLARE_SERIAL ?
the doc on MSDN says to use IMPLEMENT_SERIAL : http://msdn.microsoft.com/en-us/library/bb983718.aspx

Hi Maximilien ! Yes, you will need IMPLEMENT_SERIAL instead, if your button has own persistent members and must be serialized dynamically by the framework, of course ! :)
