STM_SETIMAGE

[曾经的猎狐]

STM_SETIMAGE
An application sends an STM_SETIMAGE message to associate a new image (icon or bitmap) with a static control.

STM_SETIMAGE

wParam = (WPARAM) fImageType; // image-type flag

lParam = (LPARAM) (HANDLE) hImage; // handle of the image


Parameters
fImageType
Value of wParam. Specifies the type of image to associate with the static control. This parameter can be one of the following values:
IMAGE_BITMAP
IMAGE_CURSOR
IMAGE_ENHMETAFILE
IMAGE_ICON


hImage
Value of lParam. Identifies the image to associate with the static control.
Return Values
The return value is the handle of the image previously associated with the static control, if any; otherwise, it is NULL

Using Static Controls

--------------------------------------------------------------------------------

The following example uses a timer and the STM_SETIMAGE message to animate an icon in a dialog box. The icon handles and the icon identifier (IDI_ICON) are defined in a global header file.

Hide Example

LRESULT CALLBACK StaticProc(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam)
{
UINT idTimer = 1;
static UINT i;

static HICON aIcons[11];

switch (message)
{
case WM_INITDIALOG:
i = 0;

// Load icons("hinst" is defined globally).

hiconOne = LoadIcon(hinst, "OneIco");
aIcons[i] = hiconOne;
hiconTwo = LoadIcon(hinst, "TwoIco");
aIcons[++i] = hiconTwo;

// Continue with the remaining icons.
// ...

i = 0;

// Use STM_SETIMAGE to associate an icon with the
// IDI_ICON identifier.

SendDlgItemMessage(hDlg, // dialog box window handle
IDI_ICON, // icon identifier
STM_SETIMAGE, // message to send
(WPARAM) IMAGE_ICON, // image type
(LPARAM) aIcons[i++]); // icon handle

// Set a timer for 50-millisecond intervals.

SetTimer(hDlg, idTimer, 50, (TIMERPROC) NULL);
return TRUE;

case WM_TIMER:

// Use STM_SETIMAGE to associate a new icon with
// the IDI_ICON identifier whenever a WM_TIMER
// message is received.
SendDlgItemMessage(hDlg, // dialog box window handle
IDI_ICON, // icon identifier
STM_SETIMAGE, // message to send
(WPARAM) IMAGE_ICON, // image type
(LPARAM) aIcons[i++]); // new icon handle
if (i == 10)
i = 0;

break;

case WM_COMMAND:
if (wParam == IDOK
|| wParam == IDCANCEL)
{
EndDialog(hDlg, TRUE);
return TRUE;
}
return 0;

case WM_DESTROY: // clean up
KillTimer(hDlg, idTimer);
// Note that DestroyIcon is not correct here.
// LoadIcon obtains a shared icon, which is valid as long
// as the module from which it was loaded is in memory.

return 0;
}
return FALSE;
UNREFERENCED_PARAMETER(lParam);
}
