How to re-arrange child window tab order

Posted on 1998-12-02

A window or dialog that contains child controls allow you jump between the child controls by using the <Tab> key.

As I understand it, the order in which the child controls are visited is determined by the creation order of the child controls.

My question is, how can I at runtime (i.e. after the child windows are created) change the tab order of the controls?

Thanks in advance,

The controls tab order in a dialog box is similar to the windows z-order. The control that is the first in tab order will have the higher z-order.
So you can use SetWindowPos to change controls tab order.

For example, if you call :
SetWindowPos(GetDlgItem(hDlg,IDOK),GetDlgItem(hDlg,IDCANCEL),SWP_NOMOVE|SWP_NOSIZE)) ;

this will cause the IDOK button to be placed after the IDCANCEL button in tab order.

To set all controls tab order, use :
SetWindowPos(GetDlgItem(hDlg,ID_xx1),HWND_BOTTOM,SWP_NOMOVE|SWP_NOSIZE)) ;
SetWindowPos(GetDlgItem(hDlg,ID_xx2),HWND_BOTTOM,SWP_NOMOVE|SWP_NOSIZE)) ;
SetWindowPos(GetDlgItem(hDlg,ID_xx3),HWND_BOTTOM,SWP_NOMOVE|SWP_NOSIZE)) ;
.

for each control in the order you want the controls to be tab ordered.

Hope this helps.

Thanks stsanz - that did indeed do the trick. I was aware of the SetWindowPos function and Z-order, but I thought it only applied to the visual appearance of the windows, not the tab order.
