Resizing dialog

[Peter Lameijn]

Is there an easy way to resize a DDT dialog window? I want to add a button
to the dialog to change the dialog size. I need to show some additional
controls then. (The button must 'flip' between 2 dialog sizes, say 400x300
and 400x400). Or would it be easier to create 2 dialog windows?

This piece resizes the status bar, use a control send w/WM_SIZE and the appropriate size and you can do it...
This window I am using is NOT a DDT, therefore I just used the sendmessage..

    Case %WM_SIZE
        Local Xsize           As Long
        Local Ysize           As Long
        GetClientRect g_hWndMain, WndRect
        Xsize = WndRect.nRight - WndRect.nLeft
        Ysize = WndRect.nBottom - WndRect.nTop
        If IsWindowVisible(g_hStatus) Then
            SendMessage g_hStatus, %WM_SIZE, wParam, lParam
            ShowWindow g_hStatus, %SW_NORMAL
            If IsWindowVisible(g_hListView) Then SetWindowPos g_hListView, 0, 0, 0, XSize, YSize-20, %SWP_NOMOVE Or %SWP_NOZORDER Or %SWP_DRAWFRAME
        Else
            If IsWindowVisible(g_hListView) Then SetWindowPos g_hListView, 0, 0, 0, XSize, YSize, %SWP_NOMOVE Or %SWP_NOZORDER Or %SWP_DRAWFRAME
        End If
        Function = 0
        Exit Function

You can use DIALOG SET SIZE for this, like:

'¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤

' Create dialog and controls, etc
'¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤¤
FUNCTION PBMAIN () AS LONG
  LOCAL hDlg AS LONG
  DIALOG NEW 0, "Resize sample",,, 195, 50, %WS_CAPTION OR %WS_SYSMENU TO hDlg
  CONTROL ADD BUTTON, hDlg, 10, "&Increase hight",  4,  4, 60, 14
  CONTROL ADD BUTTON, hDlg, 11, "&Reset size",     64,  4, 60, 14
  CONTROL ADD BUTTON, hDlg, 12, "E&xit",          130,  4, 60, 14

END FUNCTION

CALLBACK FUNCTION DlgProc() AS LONG
  IF CBMSG = %WM_INITDIALOG THEN

        DIALOG SET SIZE CBHNDL, W, H + 50 'original size + 50
     ELSEIF CBCTL = 11 THEN
        DIALOG SET SIZE CBHNDL, W, H      'original size
     ELSEIF CBCTL = 12 THEN
       DIALOG END CBHNDL
     END IF
  END IF
END FUNCTION
