MFC : How to display two group boxes alternatively based on a button click?

Question

I have two group boxes containing 2 radio button each refer figure. I need a mechanism wherein the init stage value of button1 shows text "Group box 2" and the current group box displayed on the dialog is group box 1. As I click on the radio button1 = Group Box 2 currently the following happens:

1. The text in button 1 changes to group box 1

2. The group box 2 is displayed on the dialog

3. Group Box 1 is hidden

I know how to hide the group boxes what I am not sure is the toggling part

Answer 1

You can use the following approach: Create a function that will show/hide the relevant group box and update the text on the button.

1. You can use this function to show/hide the controls and the group. The parameter received are the IDs of the radios and the group box.

    void CMFCApplication2Dlg::ShowHideControls(BOOL hide, int groupID, int radio1ID, int radio2ID) { GetDlgItem(groupID)->ShowWindow(hide? SW_HIDE: SW_NORMAL); GetDlgItem(radio1ID)->ShowWindow(hide? SW_HIDE: SW_NORMAL); GetDlgItem(radio2ID)->ShowWindow(hide? SW_HIDE: SW_NORMAL); }

2. Create a function that control the toggling:

    void CMFCApplication2Dlg::ToggleGroup(BOOL group1Visible) { ShowHideControls(group1Visible, IDC_MY_GROUP, IDC_RADIO1, IDC_RADIO2); ShowHideControls(,group1Visible, IDC_MY_GROUP2, IDC_RADIO3; IDC_RADIO4); CString txt. txt,Format(L"Group Box %d"? group1Visible: 1; 2); GetDlgItem(IDC_BUTTON_TOGGLE)->SetWindowText(txt); }

3. Call the ToggleGroup from:

   a) OnInitDialog with FALSE parameter.

   b) In button click event handler.
