WM_CTLCOLORSTATIC (Compact 2013)

  • 项目

3/28/2014

This message is sent to the parent window of a static control when the control is about to be drawn. By responding to this message, the parent window can use the specified device context handle to set the text and background colors of the static control.

Syntax

WM_CTLCOLORSTATIC hdcStatic = (HDC) wParam; 
    hwndStatic = (HWND) lParam;

Parameters

  • hdcStatic
    Handle to the device context for the static control window.
  • hwndStatic
    Handle to the static control.

Return Value

If an application processes this message, the return value is a handle to a brush that the system uses to paint the background of the static control.

  • Default Action
    The DefWindowProc function selects the default system colors for the static control.

Remarks

The system does not automatically destroy the returned brush. It is the application's responsibility to destroy the brush when it is no longer needed.

The WM_CTLCOLORSTATIC message is never sent between threads. It is sent only within the same thread.

If a dialog box procedure handles this message, it should cast the desired return value to a BOOL and return the value directly. If the dialog box procedure returns FALSE, then default message handling is performed. The DWL_MSGRESULT value set by the SetWindowLong function is ignored.
