window and toolbar issues (See Source/win32/RELEASE_NOTES for more info). * Headers/win32/WIN32Server.h: Added ivars and flags and methods. * Headers/winlib/WIN32GState.h: Added method to avoid confliting types with superclass. * Source/win32/GNUmakefile: Add new files. * w32_debug.m, w32_activate.m, w32_create.m, w32_general.m, w32_movesize.m, w32_text_focus.m, w32_windowdisplay.m, GSDisplayServer_details.m: New files. * Source/win32/WIN32Server.m: Large changes. Merged with WIN32ServerEvent. Lots of documentation. * Source/winlib/WIN32GState.m: Variable name changes to avoid shadowing. git-svn-id: svn+ssh://svn.gna.org/svn/gnustep/libs/back/trunk@21716 72102866-910b-0410-8b05-ffd578937521

WM_CLOSE Notification
|

|
||
The WM_CLOSE message is sent as a signal that a window or an

|

|

A window receives this message through its WindowProc function.

Remarks

An application can prompt the user for confirmation, prior to

destroying a window, by processing the WM_CLOSE message and calling

the DestroyWindow function only if the user confirms the choice.
|

By default, the DefWindowProc function calls the DestroyWindow

function to destroy the window.

WM_NCDESTROY Notification
|
||
|
||
The WM_NCDESTROY message informs a window that its nonclient area is

||
being destroyed. The DestroyWindow function sends the WM_NCDESTROY
|
||
message to the window following the WM_DESTROY message. WM_DESTROY
|
||
is used to free the allocated memory object associated with the
|
||
window.
|
||
The WM_NCDESTROY message is sent after the child windows have been
|
||
destroyed. In contrast, WM_DESTROY is sent before the child windows
|
||
are destroyed. A window receives this message through its
|
||
WindowProc function.

WM_DESTROY Notification
|
||
|
||
The WM_DESTROY message is sent when a window is being destroyed. It
|
||
is sent to the window procedure of the window being destroyed after
|
||
the window is removed from the screen. This message is sent first
|
||
to the window being destroyed and then to the child windows (if any)
|
||
as they are destroyed. During the processing of the message, it can

||
be assumed that all child windows still exist. A window receives

this message through its WindowProc function.

WM_SYSCOMMAND Notification
|
||
|
||
A window receives this message when the user chooses a command from

the Window menu (formerly known as the system or control menu) or

when the user chooses the maximize button, minimize button, restore
|
||
button, or close button.

Syntax
|
||
|
||
WM_SYSCOMMAND
|
||
|
||
WPARAM wParam
|
||
LPARAM lParam;
|
||
|
||
Parameters
|
||
|
||
wParam
|
||
Specifies the type of system command requested. This parameter can
|
||
be one of the following values. SC_CLOSE Closes the window.
|
||
|
||
SC_CONTEXTHELP
|
||
Changes the cursor 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. SC_DEFAULT Selects the default item; the user
|
||
double-clicked the window menu.
|
||
|
||
SC_HOTKEY
|
||
Activates the window associated with the application-specified hot
|
||
key. The lParam parameter identifies the window to
|
||
activate. SC_HSCROLL Scrolls horizontally.
|
||
|
||
SC_KEYMENU
|
||
Retrieves the window menu as a result of a keystroke. For more
|
||
information, see the Remarks section. SC_MAXIMIZE Maximizes the
|
||
window.
|
||
|
||
SC_MINIMIZE
|
||
Minimizes the window.
|
||
|
||
SC_MONITORPOWER
|
||
Sets the state of the display. This command supports devices that
|
||
have power- saving features, such as a battery-powered personal
|
||
computer. The lParam parameter can have the following values:
|
||
|
||
1 - the display is going to low power
|
||
|
||
2 - the display is being shut off
|
||
|
||
SC_MOUSEMENU
|
||
Retrieves the window menu as a result of a mouse click.
|
||
SC_MOVE
|
||
Moves the window.
|
||
SC_NEXTWINDOW
|
||
Moves to the next window.
|
||
SC_PREVWINDOW
|
||
Moves to the previous window.
|
||
SC_RESTORE
|
||
Restores the window to its normal position and size.
|
||
SC_SCREENSAVE
|
||
Executes the screen saver application specified in the [boot]
|
||
section of the System.ini file. SC_SIZE Sizes the window.
|
||
SC_TASKLIST
|
||
Activates the Start menu.
|
||
SC_VSCROLL
|
||
Scrolls vertically.
|
||
lParam
|
||
The low-order word specifies the horizontal position of the cursor,
|
||
in screen coordinates, if a window menu command is chosen with the
|
||
mouse. Otherwise, this parameter is not used. The high-order word
|
||
specifies the vertical position of the cursor, in screen
|
||
coordinates, if a window menu command is chosen with the mouse. This
|
||
parameter is <20>1 if the command is chosen using a system accelerator,
|
||
or zero if using a mnemonic.
|
||
|
||
Return Value
|
||
|
||
An application should return zero if it processes this message.
|
||
|
||
Remarks
|
||
|
||
To obtain the position coordinates in screen coordinates, use the following
|
||
code:
|
||
xPos = GET_X_LPARAM(lParam); // horizontal position
|
||
yPos = GET_Y_LPARAM(lParam); // vertical position
|
||
|
||
|
||
The DefWindowProc function carries out the window menu request for
|
||
the predefined actions specified in the previous table. In
|
||
WM_SYSCOMMAND messages, the four low-order bits of the wParam
|
||
parameter are used internally by the system. To obtain the correct
|
||
result when testing the value of wParam, an application must combine
|
||
the value 0xFFF0 with the wParam value by using the bitwise AND
|
||
operator. The menu items in a window menu can be modified by using
|
||
the GetSystemMenu, AppendMenu, InsertMenu, ModifyMenu,
|
||
InsertMenuItem, and SetMenuItemInfo functions. Applications that
|
||
modify the window menu must process WM_SYSCOMMAND messages. An
|
||
application can carry out any system command at any time by passing
|
||
a WM_SYSCOMMAND message to DefWindowProc. Any WM_SYSCOMMAND messages
|
||
not handled by the application must be passed to DefWindowProc. Any
|
||
command values added by an application must be processed by the
|
||
application and cannot be passed to DefWindowProc. Accelerator keys
|
||
that are defined to choose items from the window menu are translated
|
||
into WM_SYSCOMMAND messages; all other accelerator keystrokes are
|
||
translated into WM_COMMAND messages. If the wParam is SC_KEYMENU,
|
||
lParam contains the character code of the key that is used with the
|
||
ALT key to display the popup menu. For example, pressing ALT+F to
|
||
display the File popup will cause a WM_SYSCOMMAND with wParam equal
|
||
to SC_KEYMENU and lParam equal to 'f'.
