Symbol

Meaning

%WS_EX_APPWINDOW

Forces a top-level window onto the taskbar when the window is visible.

%WS_EX_WINDOWEDGE

Specifies that a window has a border with a raised edge.

%WS_EX_TRANSPARENT

Specifies that a window created with this style should not be painted until siblings beneath the window (that were created by the same thread) have been painted. The window appears transparent because the bits of underlying sibling windows have already been painted.

%WS_EX_TOPMOST

Specifies that a window created with this style should be placed above all non-topmost windows and should stay above them, even when the window is deactivated.

%WS_EX_TOOLWINDOW

Creates a tool window; that is, a window intended to be used as a floating toolbar. A tool window has a title bar that is shorter than a normal title bar, and the window title is drawn using a smaller font. A tool window does not appear in the taskbar or in the dialog that appears when the user presses ALT+TAB. If a tool window has a system menu, its icon is not displayed on the title bar. However, you can display the system menu by right-clicking or by typing ALT+SPACE.

%WS_EX_LTRREADING

If the shell language is Hebrew, Arabic, or another language that supports reading order alignment, the vertical scroll bar (if present) is to the left of the client area. For other languages, the style is ignored.

%WS_EX_RIGHTSCROLLBAR

Vertical scroll bar (if present) is to the right of the client area. This is the default.

%WS_EX_RIGHT

The window has generic "right-aligned" properties. This depends on the window class. This style has an effect only if the shell language is Hebrew, Arabic, or another language that supports reading-order alignment; otherwise, the style is ignored. Using the %WS_EX_RIGHT style for static or edit controls has the same effect as using the %SS_RIGHT or %ES_RIGHT style, respectively. Using this style with button controls has the same effect as using %BS_RIGHT and %BS_RIGHTBUTTON styles.

%WS_EX_PALETTEWINDOW

Combines the %WS_EX_WINDOWEDGE, %WS_EX_TOOLWINDOW, and %WS_EX_TOPMOST styles.

%WS_EX_OVERLAPPEDWINDOW

Combines the %WS_EX_CLIENTEDGE and %WS_EX_WINDOWEDGE styles.

%WS_EX_NOPARENTNOTIFY

Specifies that a child window created with this style does not send the %WM_PARENTNOTIFY message to its parent window when it is created or destroyed.

%WS_EX_MDICHILD

Creates a multiple-document interface (MDI) child window.

%WS_EX_LTRREADING

The window text is displayed using left-to-right reading-order properties. This is the default.

%WS_EX_LEFTSCROLLBAR

If the shell language is Hebrew, Arabic, or another language that supports reading order alignment, the vertical scroll bar (if present) is to the left of the client area. For other languages, the style is ignored.

%WS_EX_LEFT

Creates a window that has generic left-aligned properties. This is the default.

%WS_EX_CONTROLPARENT

The window itself contains child windows that should take part in dialog box navigation. If this style is specified, the dialog manager recourses into children of this window when performing navigation operations such as handling the TAB key, an arrow key, or a keyboard mnemonic.

%WS_EX_CONTEXTHELP

Includes a question mark in the title bar of the window. When the user clicks the question mark, the cursor changes to a question mark with a pointer. If the user then clicks a child window, the child receives a %WM_HELP message. The child window should pass the message to the parent window 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 child window. %WS_EX_CONTEXTHELP cannot be used with the %WS_MAXIMIZEBOX or %WS_MINIMIZEBOX styles.

%WS_EX_CLIENTEDGE

Specifies that a window has a border with a sunken edge.

%WS_EX_ACCEPTFILES

Specifies that a window created with this style accepts drag-drop files.

%WS_EX_STATICEDGE

Creates a window with a three-dimensional border style intended to be used for items that do not accept user input.
