First:
Bitmap point of the style on the button property page Cbitmap bitmap;
Bitmap. loadbitmap (idb_bitmap1 );
Hbitmap = (hbitmap) bitmap. Detach ();
Cbutton * pbutton = (cbutton *) getdlgitem (idcancel );
Pbutton-> setbitmap (hbitmap ); It seems that the effect is not very good. Because the image is not automatically stretched. Second:
You can use the cbuttonst control, which is more useful than those of MFC.
Assume that the button ID is idc_button1
1. Add member variables
Cbuttonst m_btn;
2. Add a bitmap resource with the ID set to idb_bitmap1.
3. In the oninitdialog function, initialize the button m_btn.subclassdlgitem (idc_button1, this );
M_btn.setbitmaps (idb_bitmap1, RGB (0, 0 ));
M_btn.offsetcolor (cbuttonst: btnst_color_bk_in, 30 );
Note: The above setbitmaps function sets the point with the color value RGB (, 0) in the image to transparent. Third:
Set the button property to ower draw.
Then map the ondrawitem message
You can draw it yourself in the ondraw function.
Void cui6dlg: ondrawitem (INT nidctl, lpdrawitemstruct)
{
If (nidctl = idc_hello_cfan)
{
// Draw the button Frame
Uint ustyle = dfcs_buttonpush;
// Do you want to press it?
If (lpdrawitemstruct-> itemstate & ods_selected)
Ustyle | = dfcs_pushed;
Cdc dc;
DC. Attach (lpdrawitemstruct-> HDC );
DC. drawframecontrol (& lpdrawitemstruct-> rcitem, dfc_button, ustyle );
// Output text
DC. SelectObject (& m_font );
DC. settextcolor (RGB (0, 0,255 ));
DC. setbkmode (transparent );
Cstring stext;
M_hellocfan.getwindowtext (stext );
DC. textout (lpdrawitemstruct-> rcitem. Left + 20, lpdrawitemstruct-> rcitem. Top + 20, stext );
// Whether the focus is obtained
If (lpdrawitemstruct-> itemstate & ods_focus)
{
// Draw a dotted box
Crect rtfocus = lpdrawitemstruct-> rcitem;
Rtfocus. deflaterect (3, 3 );
DC. drawfocusrect (& rtfocus );
}
Return;
}
Cdialog: ondrawitem (nidctl, lpdrawitemstruct );
} Fourth: 1. Select the button attribute onwer Drew. The button ID is idc_button1.
2. Define the private variable:
Cbitmapbutton m_button;
3. During Initialization
M_button.loadbitmaps (_ T ("idb_bitmap3"), _ T ("idb_bitmap4"), _ T ("idb_bitmap3"), _ T ("idb_bitmap5 ")); M_button.subclassdlgitem (idc_button1, this );
M_button.sizetocontent (); This method also works. |
