CResizableSheet(Ex) and CResizablePage(Ex)

These four classes handle resizable property sheets, and are now fully based on my ResizableLib class library.

The user will have the ability to resize the dialog, with consequent rearrangement of child windows. You can control the minimum and maximum size allowed, as well as the maximized size and position of the dialog. The size grip is displayed by default, but you may turn it off. Automatic Save/Restore the dialog's size and position, along with the active page, is also supported.

The Sample Applications

This is a view of the sample dialog at minimum size as a property sheet and in wizard mode:

Note that the minimum width is not the default. You may see how to do this in the next section.

This is a screenshot of the resizable version of Wizard2000 sample project coming with Visual C++.

How to use?

Add the ResizableLib to your project's workspace, as explained in the relative.

Create a property sheet or wizard dialog and do the relative associations with MFC classes, for example using the Property Sheet component, or take one you have already made which you want to be resizable. You don't need to change any window style to have the dialog resizing.

Include 'ResizableSheet.h' in the property sheet associated header file.

Search and replace all CPropertySheet occurences with CResizableSheet in both your .cpp and .h files, just as if your property sheet class was derived from CResizableSheet instead of CPropertySheet.

Include 'ResizablePage.h' in the property pages associated header file.

Search and replace all CPropertyPage occurences with CResizablePage in both your .cpp and .h files, just as if your property page classes were derived from CResizablePage instead of CPropertyPage.

The same applies for wizard dialogs, of course.

Your property sheet header file should appear like this:

// MyPropertySheet.h : header file
//

#include "MyPropertyPages.h"

/////////////////////////////////////////////////////////////////////////////
// CMyPropertySheet

#include "ResizableSheet.h"

class CMyPropertySheet : public CResizableSheet
{
    DECLARE_DYNAMIC(CMyPropertySheet)

// Construction
public:
    CMyPropertySheet(CWnd* pWndParent = NULL);

// ( other stuff )
// ...
}

In your OnInitDialog override you may change the initial settings of your property sheet, such as the minimum size and automatic save/restore, that can optionally set also the active page.

BOOL CMyPropertySheet::OnInitDialog() 
{
    CResizableSheet::OnInitDialog();
    
    // set minimal size
    CRect rc;
    GetWindowRect(&rc);

    SetMinTrackSize(CSize(GetMinWidth(), rc.Height()));

    // enable save/restore, with active page
    EnableSaveRestore(_T("Properties"), TRUE, TRUE);

    return TRUE;
}

Your property pages header file should appear like this:

// MyPropertyPages.h : header file
//

/////////////////////////////////////////////////////////////////////////////
// CMyPropertyPage1 dialog

#include "ResizablePage.h"

class CMyPropertyPage1 : public CResizablePage
{
    DECLARE_DYNCREATE(CMyPropertyPage1)
// ...
}

// and so on for the other pages ...

In each page's OnInitDialog override you only have to set a layout for your controls. You specify where to attach the top-left and bottom-right corners by horizontal/vertical percentage or using predefined constants.

BOOL CMyPropertyPage2::OnInitDialog() 
{
    CResizablePage::OnInitDialog();
    
    // preset layout
    AddAnchor(IDC_LIST1, TOP_LEFT, CSize(50,70));
    AddAnchor(IDC_PICTURE1, CSize(50,0), CSize(100,70));
    AddAnchor(IDC_GROUP1, CSize(0,70), BOTTOM_RIGHT);
    AddAnchor(IDC_CHECK1, CSize(0,85));
    AddAnchor(IDC_RADIO1, CSize(100,85));
    AddAnchor(IDC_COMBO1, CSize(100,70));
    AddAnchor(IDC_BUTTON1, BOTTOM_RIGHT);

    m_ctlEdit1.AddString(_T("Just a single item to test the "
        "listbox behavior with very long lines..."));
    m_ctlEdit1.SetHorizontalExtent(300);

    return TRUE;
}

You are ready to rebuild your project and you will have a resizable property sheet or a wizard dialog just as you wanted.
