Swap Button Positions

[Max Payne]

Hi Guys,

I have here a simple problem that I could not figure how to do it. I have two buttons, lets say button 1 and 2, I need to swap these button to each others position. This means That button 1 will take button 2 position in the dialog and button 2 will take button 1 position.

For the time being, I changing the text on the button and it looks like its swapping but its just changing the text.

void CPLAYDlg::OnButton(UINT uID) 
{
    // TODO: Add your control notification handler code here
    SetDlgItemText(uID,"0");
    CString str;
    str.Format ("%d",uID-1000);
    SetDlgItemText(IDC_BUTTON0,str);    
} 

in the above code, I changed the text of button 0 with the button with uID as ID. Any one can help me on this????
Thank You.

Do you need to do this permanently (i.e. from start-up) or are you saying that you want to the buttons to be swapping positions while the program is actually running?

Tha buttons is supposed to swap when one of the buttons is clicked. And it should not be permanent as as I may add more buttons and add the same functionality to swap between each other.Is that possible??

Max - I've heard of some great ways to confuse your users but that one deserves a prize...!

Try something like this for each of the buttons (I haven't tested the code but it should work)

GetDlgItem(IDC_BUTTONx)->MoveWindow(newXPos, newYPos, newWidth, newHeight);
GetDlgitem(IDC_BUTTONx)->ShowWindow(SW_HIDE);
GetDlgitem(IDC_BUTTONx)->ShowWindow(SW_SHOWNA);

You might have to experiment with 'SW_SHOWNA'. If it doesn't work, try SW_SHOW or SW_SHOWNORMAL

Good luck!

void FOO_DIALOG::SwapButtons(CButton& button1, CButton& button2)
{
	CRect rect1, rect2;
	button1.GetWindowRect(&rect1);
	button2.GetWindowRect(&rect2);
	ScreenToClient(&rect1);
	ScreenToClient(&rect2);
	Button1.MoveWindow(&rect2);
	Button2.MoveWindow(&rect1);
}

Didn't test it

That just what I wanted. Thanks both of you.

Pleasure - incidentally, I've sometimes found that changing a window's style or position - e.g. MoveWindow(), SetWindowPos(), ModifyStyle() etc - can't be relied upon to work immediately in all flavours of Windows. Sometimes the window isn't moved or re-styled until it next gets re-drawn - therefore it's a good idea to force a re-draw by hiding the window and re-showing it again.

You could also use SetDlgCtrlID() and swap the control id's. Combine this with swapping the button text, it might be easier that moving everything around. Plus, this method should preserve the tab ordering or the buttons.
