Add a splitter popup button that doesn't disappear
If you have created a splitter popup button as shown below, it will disappear when the ‘Reset Toolbar’ button is clicked.
pStandardBar->GetControls()->Add(xtpControlSplitButtonPopup, ID_BUTTON_POPUP);
If you use Customizable toolbars you must avoid dynamic creation of controls. You must use the ‘Xtreme Control Sub classing’ technique. To add a splitter button do the following:
1. Add the button to your toolbar resource using the Visual Studio resource editor like so:
2. Using the resource editor, create a Popup menu with same command id as the toolbar button you just added.
3. Add the command handler ON_XTP_CREATECONTROL() to your CMainFrame message map.
BEGIN_MESSAGE_MAP(CMainFrame, CFrameWnd)
//{{AFX_MSG_MAP(CMainFrame)
...
//}}AFX_MSG_MAP
ON_XTP_CREATECONTROL()
END_MESSAGE_MAP()
int CMainFrame::OnCreateControl(LPCREATECONTROLSTRUCT lpCreateControl)
{
if (lpCreateControl->bToolBar)
{
if (lpCreateControl->nID == ID_BUTTON_POPUP)
{
lpCreateControl->controlType = xtpControlSplitButtonPopup;
return TRUE;
}
}
return FALSE;
}
4. Add the following line to your header file for CMainFrame:
afx_msg int OnCreateControl(LPCREATECONTROLSTRUCT lpCreateControl);
