Using a Modeless Dialog Box

When an application displays a modeless dialog box, the application does not halt, waiting for user input, but continues executing. The user can freely switch between the modeless dialog box and the other windows in the application.

To display a modeless dialog box, call the DLGMODELESS function. A modeless dialog box remains displayed until the DLGEXIT routine is called, either explicitly or by a default button callback. The application must provide a message loop to process Windows messages and must call the DLGISDLGMESSAGE function at the beginning of the message loop.

The variable of type DIALOG passed to DLGMODELESS must remain in memory for the duration of the dialog box (from the DLGINIT call through the DLGUNINIT call). The variable can be declared as global data in a Fortran module, as a variable with the STATIC attribute (or statement), or in a calling procedure that is active for the duration on the dialog box. For more information, see the Syntax for DLGMODELESS.

Modeless dialog boxes are typically used in a Fortran Windows project. A modeless dialog box can be used in a Fortran Console, Fortran DLL, or Fortran Static Library application as long as the requirements for using a modeless dialog box (discussed in the previous paragraphs) are met.

As an example of using a modeless dialog box, the following code is the WinMain function of an application that displays a modeless dialog box as its main window: 

    INTEGER(DWORD) function WinMain (hInstance, hPrevInstance, &
& lpszCmdLine, nCmdShow)
    !DEC$ ATTRIBUTES STDCALL, DECORATE, ALIAS:”WinMain”  :: WinMain
    use IFWIN
    use IFLOGM
    INTEGER(HANDLE), INTENT(IN) :: hInstance, hPrevInstance
    INTEGER(LPVOID), INTENT(IN) :: lpszCmdLine
    INTEGER(DWORD), INTENT(IN) :: nCmdShow
    ! Include the constants provided by the Resource Editor
    include 'resource.fd'
    ! A dialog box callback
    external ThermometerSub
    ! Variables
    type (dialog) dlg
    type (T_MSG)  mesg
    integer ret
    logical lret
    ! Create the thermometer dialog box and set up the controls and callbacks
    lret = DlgInit(IDD_THERMOMETER, dlg_thermometer)
    lret = DlgSetSub(dlg_thermometer, IDD_THERMOMETER, ThermometerSub)
    lret = DlgSet(dlg_thermometer, IDC_PROGRESS1, 32, DLG_RANGEMIN)
    lret = DlgSet(dlg_thermometer, IDC_PROGRESS1, 212, DLG_RANGEMAX)
    lret = DlgSet(dlg_thermometer, IDC_PROGRESS1, 32)
    lret = DlgModeless(dlg_thermometer, nCmdShow)
 
    ! Read and process messages until GetMessage returns 0 because
    ! PostQuitMessage has been called
    do while( GetMessage (mesg, NULL, 0, 0) )
       ! Note that DlgIsDlgMessage must be called in order to give
       ! the dialog box first chance at the message.
       if ( DlgIsDlgMessage(mesg) .EQV. .FALSE. ) then
           lret = TranslateMessage( mesg )
           ret  = DispatchMessage( mesg )
       end if
    end do
    ! Cleanup dialog box memory
    call DlgUninit(dlg)
    ! The return value is the wParam of the Quit message
    WinMain = mesg.wParam
    return
  end function
