resize a CFormView programmatically
-
Greetings, I am trying to change the size of a FormView application after I have resized a control and I must be missing something essential. I can get the window to resize (smaller), but then scroll bars appear that weren't there before. I suspect it is something inherent to how a FormView works as when I resize smaller manually, the scroll bars appear even though no controls are obscured. I suspect I have some setting in the FormView wrong since it doesn't behave with manual resizing. Anyway... My current approach is to call AfxGetMainWnd()->GetWindowPos(), adjust the values and then call SetWindowPos(). Then I call ResizeParentToFit() which almost does the job. Here is a code fragment. The control involved is a CListCtrl...
WINDOWPLACEMENT wpMain, wpOldList;
AfxGetMainWnd()->GetWindowPlacement(&wpMain);
m_RecordList.GetWindowPlacement(&wpOldList);... make the size and content changes to the list ...
WINDOWPLACEMENT wpNewList;
m_RecordList.GetWindowPlacement(&wpNewList);int sizeChange = wpOldList.rcNormalPosition.right - wpNewList.rcNormalPosition.right;
wpMain.rcNormalPosition.right -= sizeChange;
AfxGetMainWnd()->SetWindowPlacement(&wpMain);
ResizeParentToFit();Any hints would be greatly appreciated. Thanks!

I'm not sure to understand, so I hope I won't provide a bad answer. As I understand it, you want to force the size of your application. I would do so by resizing the MainFrame object, using CMainFrame::SetWindowPos. Then I would catch the WM_SIZE message in the Form View to handle controls size and position changes. Oh, and you can manage the way your view handles scroll bars by overring CScrollView::SetScrollSizes. HTH,

I've tried using SetWindowPos(), but it works no better. Catching the OnSize stuff would not help as the control has already been sized; there is nothing to be done. Manually (or rather programatically) adjusting the scroll bar is something I would like to avoid. For now, I am using a kludge by setting the original size of the Formview and the control that gets resized (in the visual dialog editor) to something absurdly small. Then when I load up the control and resize it, I can also resize the MainFrame and it seems to work. No annoying, unneeded scrollbars appear. But this seems like an inelegant solution. Surely there is a better way!

I suppose the code you indicated is in a method of the Form View, right? Did you try to resize the view using
/*CFormView::*/SetWindowPos()instead ofAfxGetMainWnd()->SetWindowPos()(which would resize the main frame) and then calling ResizeParentToFit which should resize the Main Frame according to the size of the view?

I'll try that when I get home. Thanks!

What I am doing now is use WindowSetPos() and SetScrollSizes. Pretty much as you suggested. I didn't understand from the documentation what SetScrollSizes did. It just sets the the threhold for window size for when the scrollbars appear. Which is what I needed. Thanks for your help.
