CFormView control sizing

[xrg_soft 163 com]

The window size is never specified when you first call pGridCtrl->GetWindowRect(grid_rect); in the OnInitialUpdate. Please write some codelike below in your CMembersView::OnSize

CWnd *pGridCtrl = this->GetDlgItem(IDC_MEMBERSGRID);
ASSERT(pGridCtrl); // Must exist
if ( ::IsWindow(pGridCtrl->GetSafeHwnd()) )
{
pGridCtrl->MoveWindow(..

IIRC GetXXXRect take pointers as parameters. Have you tried with

pGridCtrl->GetWindowRect(**&**grid_rect);

Same comment for the GetClientRect call a few line above.

This is working fine :-

void CMainView::OnInitialUpdate() // CMainView is my application's default view
{
CFormView::OnInitialUpdate();

initialized = TRUE;
CWnd \*pGridCtrl = GetDlgItem(IDC\_SALEPURCHASEGRIDCTRL);
CRect rect,grid\_rect;

CWnd \*pWnd = this->GetOwner();
pWnd->GetClientRect(rect);


pGridCtrl->GetWindowRect(grid\_rect);     // works fine here
grid\_rect = rect;
grid\_rect.left += 16;
grid\_rect.top += 150;
grid\_rect.bottom -= 300;
grid\_rect.right -= 16;

pGridCtrl->MoveWindow(grid\_rect);        // GridCtrl is resized properly

.
.
.

This is not working properly:-

void CMembersView::OnInitialUpdate()
{

CFormView::OnInitialUpdate();

initialized = TRUE;
CWnd \*pGridCtrl = this->GetDlgItem(IDC\_MEMBERSGRID);
ASSERT(pGridCtrl);		// Must exist

CRect rect,grid\_rect;

CWnd \*pWnd = this->GetOwner();
pWnd->GetClientRect(rect);                // Also tried with &rect

pGridCtrl->GetWindowRect(grid\_rect); // problem is here. no grid\_rect coordinates.   Also tried with &grid\_rect
grid\_rect = rect;
grid\_rect.left += 16;
grid\_rect.top += 150;
grid\_rect.bottom -= 300;
grid\_rect.right -= 16;

pGridCtrl->MoveWindow(&grid\_rect);

Doesn't help much.

Are the coordinate that should be returned by GetWindowRect really null ? What does the debugger says (if you look into the pGridCtrl structure) ? Have tried GetLastError ?

[Manmohan29]

In CMainView :- grid_rect {top=-0 bottom=912 left=0 right=1819} CRect In CMembersView :- grid_rect {top=-32639 bottom=-32483 left=-32709 right=-31884} CRect

Actually, you are overwriting grid_rect in the next part of the code with the content of rect, making the GetWindowRect call unnecessary. What if you comment out this line pGridCtrl->GetWindowRect(grid_rect); ? ( just to test if the MoveWindow is accepted).

[Manmohan29]

I use it to just test whether grid_rect fetches some values or not. Ok. I comment it out. But still it doesn't help.

Then I guess the OP was right and the structure/window is not initialized properly at this point of time. So either this is the standard behaviour, and you will have to initialize it in another event, or something goes wrong when creating the GridCtrl.

I guess you do not catch all my meaning. If you just set the grid position in OnInitialUpdate, then even it works. There still some problem after you resize your application. To make sure it works in all case, you must do it inside OnSize

CMembersView::OnSize:
CWnd *pGridCtrl = this->GetDlgItem(IDC_MEMBERSGRID);
ASSERT(pGridCtrl); // Must exist
if ( ::IsWindow(pGridCtrl->GetSafeHwnd()) )
{
// assume you need to move the grid to the left half of CMembersView
CRect rctClient;
this->GetClientRect(&rctClient);
pGridCtrl->MoveWindow(0, 0, rctClient.Width()/2, rctClient.Height());
}
