position panels evenly across window

[prettitoni]

Hi there.

I've been struggling with this for a bit now and it might just be a quick algorithm and I'm missing something. I'm using VC++ 2005. I have 5 panels (all the same size) on a windows form and I want them positioned across the width of the form. I want one panel on the leftmost side, one panel on the rightmost side and the remaining 3 panels evenly distributed in between. The number of panels may change so I want to do this in a flexible way. Can someone please help me with the algorithm?

Thanks.

Unfortunately I do not have .Net installed at the moment so here's some MFC code you can modify to work.

UINT ids[] ={IDC_EDIT1,IDC_EDIT2,IDC_EDIT3,IDC_EDIT4,IDC_EDIT5};
int numItems = 5;
	
RECT crec,itemRect;
CWnd* base = GetDlgItem(ids[0]);
if(base)
{
    base->GetWindowRect(&itemRect);
    ScreenToClient(&itemRect);

    GetClientRect(&crec);
    int clientWidth = (crec.right - crec.left);
    CWnd** lplpWnd = new CWnd*[numItems];
    for (int i = 0; i < numItems; i++)
    {
	lplpWnd[i] = GetDlgItem(ids[i]);
    }

    int totalItemWidth = ((itemRect.right - itemRect.left) * numItems);
    int Gap = ((clientWidth - totalItemWidth)/(numItems - 1));
    if(Gap > 0)
    {
	for(int n = 0; n < numItems; n++)
	{
	    lplpWnd[n]->MoveWindow((n*((itemRect.right - itemRect.left)+Gap)),
            itemRect.top,
	    (itemRect.right - itemRect.left),
	    (itemRect.bottom - itemRect.top));
	}
    }
    delete [] lplpWnd;
}

for example replace

movewindow

with

panels[n].Location = New Point(n*((itemRect.right - itemRect.left)+Gap)),panels[n].Top);

and

GetClientRect

with

panel1.ClientRectangle

I will post a windows forms version soon as I install VC++ .Net

Heres the same thing in windows forms.

int numItems = 5;

System::Windows::Forms::Panel* pannels[] = new System::Windows::Forms::Panel* [numItems];

pannels[0] = panel1;
pannels[1] = panel2;
pannels[2] = panel3;
pannels[3] = panel4;
pannels[4] = panel5;

int totalItemWidth = (pannels[0]->Width * numItems);
int Gap = ((ClientRectangle.Width - totalItemWidth)/(numItems - 1));
if(Gap > 0)
{
    for(int n = 0; n < numItems; n++)
    {
        pannels[n]->Location = Point((n*(pannels[0]->Width+Gap)),pannels[0]->Top);
    }
}
