destroying one view from another view - beginner

ns10-Jul-02 2:38

10-Jul-02 2:38

I see hoew to get the oh-so useful document pointer a lot, but if I want to destroy view2 from view1, how do I do that? If I had launched a dialog from my view, then I'd have the name like:

CMyDialog cDlg;

etc

cDlg.DestroyWindow.

But I didnt spawn view2 from view1, so how to I get its name or pointer to call DestroyWindow on it?

Thanks,
ns

You still need to go via that magic document. The document keeps pointers to all its views, which you can get access to via CDocument::GetFirstViewPosition() and CDocument::GetNextView() (which uses MFC's less than intuitive POSITION based iteration method - look the two methods up in the MSDN Library for details).

You can either call those methods from one view (using the view's pointer to its document) to destroy the other view, or you can define a method in your document which you call from one view to close the other. I prefer the second method, because it means the views don't have to know too much about the views they coexist with.

I´d try this :

// Win32 API:
HICON hLargeIcon = LoadIcon ( hinstYourModuleInstance, 
                              MAKEINTRESOURCE(IDI_NEW_ICON) );
HICON hSmallIcon = (HICON) LoadImage ( hinstYourModuleInstance, 
                                       MAKEINTRESOURCE(IDI_NEW_ICON),
                                       IMAGE_ICON, 16, 16, LR_DEFAULTCOLOR );
 
  SendMessage ( hwndYourWindow, WM_SETICON, ICON_BIG, hLargeIcon );
  SendMessage ( hwndYourWindow, WM_SETICON, ICON_SMALL, hSmallIcon );

During the initialization of your app's main window, you can load an icon from your resources like so:

<br />
WNDCLASS  wc;<br />
	<br />
wc.lpfnWndProc		= (WNDPROC)MainWndProc; <br />
wc.lpszClassName	= _T("MyAppClass");<br />
...<br />
wc.hIcon		= LoadIcon( hInstance, IDI_APPICON );<br />
...<br />
<br />
// Register the main windows class settings.<br />
if ( ! RegisterClass( &wc ) )<br />
   return FALSE;<br />

Add a resouce file (*.rc) to your project. Insert an icon (the one you want to use). Compile your application. If you import more than one icon, the compiler will arrange the icon resource ID's in alphabetical order. The first icon will then be associated with the EXE.

updateAllViews() - quick question

ns10-Jul-02 2:15

10-Jul-02 2:15

Hello,

If I want all views to update, its UpdateAllViews(NULL);

All other views but the sender -- UpdateAllViews(this);

What do I do if I want to update only my current view and none of the others?

Thank you very much,
ns

Re: updateAllViews() not in class wizard??

ns10-Jul-02 2:26

10-Jul-02 2:26

I was expecting to see the function UpdateAllViews in the classwizard entries for my doc class. There are functions like: setPathName, setTitle, GetNextView etc but not UpdateAllViews. Since its a CDocument object I can look in the MSDN for members, but why doesnt the class wizard have a list of all member functions, not just some? Why are the ones that are there, there?

Thanks,
ns

call OnUpdate directly

Richard Stevens has published the 'bible' on socket programming. Get TCP/IP Illustrated Volume 1 (I've got all 3 volumes). Easy to understand and a great book to learn TCP/IP network coding.

I agree. His books are outstanding. Another one that has been very helpful to me is Network Programming for Windows by Anthony Jones and Jim Ohlund.

list control with checkboxes - newbie

ns10-Jul-02 1:37

10-Jul-02 1:37

By default, clicking on the item text in a listcontrol with extended style checkboxes, does not set the check in the checkbox. How do I make it so that when I click on the name, the check is set and the app responds as if to an actual direct check in the checkbox?
Thank you.
ns

Re: list control with checkboxes - newbie

Mike Upton10-Jul-02 4:08

You can't make the list control do that automatically (there's no style bit or extended style bit to do it) so you'll have to add some code.

You need a notify handler for NM_CLICK. If the user left clicks on the icon or the first column label, the NMITEMACTIVATE.iItem member will contain the index of the item clicked on, so you can then set the check state of the item.

In MFC, your code will look something like this, assuming you're handling the notification in the parent window of the list control:

//In the message map of the parent window
ON_NOTIFY(NM_CLICK, ID_YOUR_LIST_CONTROL, OnClickYourListControl)

...

//Handler function
void OnClickYourListControl(NMHDR* pNMHDR, LRESULT* pResult)
{
  NMITEMACTIVATE* pItem = (NMITEMACTIVATE*)pNMHDR;

  //If the user clicked on the icon or the first column, iItem is valid
  if (pItem->iItem > -1)
  {
    //You'll probably have a pointer to the list control, but if not...
    CListCtrl* pList = (CListCtrl*)CWnd::FromHandle( (pItem->hdr).hwndFrom );
    ASSERT(pList!=NULL);

    //Toggle the check state
    pList->SetCheck( pItem->iItem, !pList->GetCheck(pItem->iItem) );
  }

  //Doesn't matter what you do with pResult
  *pResult=0;
}

If you're handling the notification in the list control itself, you'll need to use the reflected message instead, via the ON_NOTIFY_REFLECT macro.

Re: list control with checkboxes Thanks!!!

Thanks so much for the direction. I am trying it out. For the checkboxes I have:

m_list3.SetExtendedStyle(LVS_EX_CHECKBOXES);

where m_list3 is a listcontrol.

Have you already tried something with SetWindowPos() (Throw an eye in the MSDN for further infos) ?

~RaGE();

Re: Children in back?

Dov Sherman10-Jul-02 12:00

Dov Sherman

10-Jul-02 12:00

Yes, I looked into SetWindowPos(). The problem is that when SetWindowPos() changes the Z-order of a window, it automatically changes the Z-order of any windows owned by that window. So if I tell it to put my main window in front of a child, it does it and then puts the child in front of the main window again.
