DLGISDLGMESSAGE, DLGISDLGMESSAGEWITHDLG
Dialog Functions: Determine whether the specified message is intended for one of the currently displayed modeless dialog boxes, or a specific dialog box. These routines are only available for Windows.
Module
USE IFLOGM
result = DLGISDLGMESSAGE (mesg)
result = DLGISDLGMESSAGEWITHDLG (mesg, dlg)
mesg |
(Input) Derived type T_MSG. Contains a Windows message. |
dlg |
(Input) Derived type dialog. Contains dialog box parameters. The components of the type dialog are defined with the PRIVATE attribute, and cannot be changed or individually accessed by the user. |
Results
The result type is LOGICAL(4). The result is .TRUE. if the message is processed by the dialog box. Otherwise, the result is .FALSE. and the message should be further processed.
DLGISDLGMESSAGE must be called in the message loop of Windows applications that display a modeless dialog box using DLGMODELESS. DLGISDGMESSAGE determines whether the message is intended for one of the currently displayed modeless dialog boxes. If it is, it passes the message to the dialog box to be processed.
DLGISDLGMESSAGEWITHDLG specifies a particular dialog box to check. Use DLGISDLGMESSAGEWITHDLG when the message loop is in a main application and the currently active modeless dialog box was created by a DLL.
Example
use IFLOGM
include 'resource.fd'
type (DIALOG) dlg
type (T_MSG) mesg
integer*4 ret
logical*4 lret
...
! Create the main dialog box and set up the controls and callbacks
lret = DlgInit(IDD_THERM_DIALOG, dlg)
lret = DlgSetSub(dlg, IDD_THERM_DIALOG, ThermSub)
...
lret = DlgModeless(dlg, nCmdShow)
...
! Read and process messsages
do while( GetMessage (mesg, NULL, 0, 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 and exit the application
call DlgUninit(dlg)
WinMain = mesg%wParam
