New Dialog Styles in Windows 95

• Microsoft Win32 Application Programming Interface (API) included with:

      - Microsoft Windows 95 version 4.0
  

SUMMARY

Windows 95 provides a few new dialog styles -- all listed in this article. All Windows version 3.1 dialog styles are still usable in Windows 95. However, DS_LOCALEDIT cannot be used in Win32-based applications because it does not apply. Although not documented, DS_ABSALIGN and DS_SETFONT exist in Windows version 3.1. They are documented in Windows 95.

MORE INFORMATION

Here is a list of the new dialog styles:

DS_3DLOOK          Gives the dialog box a nonbold font and draws
                   three-dimensional borders around control windows
                   in the dialog box.

DS_CENTER          Centers the dialog box in the working area -- the
                   area not obscured by the tray.

DS_CENTERMOUSE     Centers the mouse cursor in the dialog box.

DS_CONTEXTHELP     Includes a question mark in the title bar of the
                   dialog box. When the user clicks the question mark,
                   the cursor changes to a question mark with a
                   pointer. If the user then clicks a control in the
                   dialog box, the control receives a WM_HELP message.
                   The control should pass the message to the dialog
                   procedure, which should call the WinHelp function
                   using the HELP_WM_HELP command. The Help
                   application displays a pop-up window that
                   typically contains help for the control. Note that
                   DS_CONTEXTHELP is just a placeholder. When the dialog
                   box is created, the system checks for DS_CONTEXTHELP
                   and, if it is there, adds WS_EX_CONTEXTHELP to the
                   extended style of the dialog box.

DS_CONTROL         Creates a dialog box that works well as a child
                   window of another dialog box, much like a page in
                   a property sheet. This style allows the user to
                   tab among the control windows of a child dialog
                   box, use its accelerator keys, and so on.

DS_FIXEDSYS        Uses SYSTEM_FIXED_FONT instead of SYSTEM_FONT.

DS_NOFAILCREATE    Creates the dialog even if errors occur -- for
                   example, if a child window cannot be created
                   or if the system cannot create a special data
                   segment for an edit control.

DS_SETFOREGROUND   Brings the dialog box to the foreground.
                   Internally, Windows calls the SetForegroundWindow
                   function for the dialog box.
