Putting control bars in a dialog

There's some discussion of this in Microsoft Knowledge Base Article Q141751.

Putting control bars in a dialog

This is initially quite simple:

class CCustomDrawDlg : public CDialog
{
    // See Q141751
    CDialogToolBar m_wndToolBar;
    CStatusBar m_wndStatusBar;
    // ...

int CCustomDrawDlg::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
    if (CDialog::OnCreate(lpCreateStruct) == -1)
	return -1;

    if (!m_wndToolBar.CreateEx(this) ||
	!m_wndToolBar.LoadToolBar(IDR_MAINFRAME))
    {
	TRACE0("Failed to create toolbar\n");
	return -1;      // fail to create
    }

    if (!m_wndStatusBar.Create(this))
    {
	TRACE0("Failed to create statusbar\n");
	return -1;
    }

    return 0;
}

Using RepositionBars

void CCustomDrawDlg::OnSize(UINT nType, int cx, int cy)
{
    RecalcLayout();

    CDialog::OnSize(nType, cx, cy);
}

void CCustomDrawDlg::RecalcLayout()
{
    CRect client;
    GetClientRect(&client);

    CRect remaining;
    RepositionBars(0, 0xffff, AFX_IDW_PANE_FIRST, CWnd::reposQuery, &remaining, &client);
    RepositionBars(0, 0xffff, AFX_IDW_PANE_FIRST, CWnd::reposDefault, NULL, &client);

    // TODO: reposition the other controls, using remaining
}

Using a status bar to provide sizing

It's magic -- it just works. If you put a status bar in your dialog, and position it correctly, the user can resize your window using the size box on its corner.
