Please read the description in the header comment:

Code: Select all
Dscr:         Places passed controls (like buttons) in the center of their parent window HORIZONTALLY.
            This function is useful when different sets of buttons are displayed under different conditions
            and the buttons should be placed in the middle to look nice (no matter how many buttons).
            For example, there are 4 buttons in the window - cb_ok, cb_yes, cb_no, cb_cancel:
            CommandButton   lcb_buttons[]
            if <some condition> then
               lcb_buttons[] = {cb_yes, cb_no, cb_cancel}
               lcb_buttons[] = {cb_ok, cb_cancel}
            end if
            The function also makes the displayed controls visible, so make all the controls invisible by default.
Arg:         ado_controls[] (array of DragObject)
Developer:   Michael Zuskin -  http://linkedin.com/in/zuskin | http://code.intfast.ca/
int      li_count // quantity of controlls to center
int      i
int      li_frag_len // "fragment" is the distance between the beginning of the 1st control and the end of the last one
int      li_X
window   lw_parent

constant int SPACE = 15 // between controls

li_count = UpperBound(ado_controls[])
if li_count = 0 then return

// Calculate fragment's length:
for i = 1 to li_count
   li_frag_len += ado_controls[i].Width + SPACE
li_frag_len -= SPACE

// Calculate X coordinate (on the window) of 1st control:
lw_parent = ado_controls[1].GetParent()
li_X = (lw_parent.Width - li_frag_len) / 2

// Place all controls:
for i = 1 to li_count
   ado_controls[i].Visible = true
   ado_controls[i].X = li_X
   li_X += ado_controls[i].Width + SPACE // "move" X to right, i.e. calc it for next control


For Canadians: you should name this function uf_display_in_centRE()! :lol: :lol: :lol:
