WM_SETFONT
An application sends a WM_SETFONT message to specify the font that a control
is to use when drawing text.
WM_SETFONT
wParam = (WPARAM) hfont; // handle of font
lParam = MAKELPARAM(fRedraw, 0); // redraw flag
Parameters
hfont
Value of wParam. Identifies the font. If this parameter is NULL, the control uses the default
system font to draw text.
fRedraw
Value of lParam. Specifies whether the control should be redrawn immediately upon setting the
font. Setting the fRedraw parameter to TRUE causes the control to redraw itself.
Return Values
This message does not return a value.
Remarks
The WM_SETFONT message applies to all controls, not just those in dialog
boxes.
The best time for the owner of a dialog box control to set the font of the
control is when it receives the WM_INITDIALOG message. The application should call the DeleteObject function to delete the font when it is no longer needed; for example, after
it destroys the control.
The size of the control does not change as a result of receiving this message.
To avoid clipping text that does not fit within the boundaries of the control,
the application should correct the size of the control window before it sets
the font.
When a dialog box uses the DS_SETFONT style to set the text in its controls,
Windows sends the WM_SETFONT message to the dialog box procedure before it
creates the controls. An application can create a dialog box that contains the
DS_SETFONT style by calling any of the following functions:
- CreateDialogIndirect
- CreateDialogIndirectParam
- DialogBoxIndirect
- DialogBoxIndirectParam

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
