Introduction

This control works like the 'Rollout panel' in 3dsmax. When you click on a checkbox, some additional controls are shown. Another click on a checkbox will hide controls. Notice that other controls in a dialog are also moved and the dialog itself is resized. I tried to find something like this on the CodeProject, but the only articles I found were about expanding dialogs, which has limited functionality in comparison with this. So I decided to write my own class for this control.

How to integrate it into existing code

1. Create a dialog and place controls on it.
2. Encircle controls you want to be dynamically shown or hidden with static box and set it's text to empty string, also place checkbox in the corner of it, as it is shown in the picture
3. Set the proper IDs for checkbox and static (do not use IDC_STATIC because it will not work!). Let's say you have used IDs IDC_CHTYPE (for checkbox) and IDC_STTYPE (for static box)
4. Associate variables with these two controls using Class Wizard. The should be of type CButton
5. Copy ExpandingCheck.h and ExpandingCheck.cpp files into your source files directory
6. In your dialog's .h file write:

#include"ExpandingCheck.h" 

7. Also in your dialog's .h file you have to find the variables created in Step 4 and make the Checkbox variable of type CExpandingCheck

//{{AFX_DATA(CExpCheckTestDlg)
enum { IDD = IDD_EXPCHECKTEST_DIALOG };
CExpandingCheck m_chType; //I have changed this line
CButton m_stType;
//}}AFX_DATA

8. In the constructor of your dialog, write:

   m_chType.SetFrame(&m_stType); 

9. That's all!
