Thread: [win32] - how use the button face?

when i ownerdraw a button, can i get the button faces?
(for then add the image and text)

The BS_OWNERDRAW style requires that you draw everything, including the button itself.
The buttons are handled as menu items rather than buttons, but allow you to completely
design the button yourself. However, this also means that you will have to also draw
the "button pushed" state yourself when the button is clicked on.

All drawing should be done in response to a WM_DRAWITEM message:

WM_DRAWITEM message (Windows)

The lParam with this message contains a pointer to a DRAWITEMSTRUCT structure:

DRAWITEMSTRUCT structure (Windows)

The rcItem member of this structure is a rectangle for the "surface" of the button.

You have to be careful to not draw outside of the button rectangle. The drawing is not clipped
as it is with other drawing procedures like drawing in the client area.

sorry.. but i continue with the problem: i know draw rectangles and text and bitmaps\icons, my problem is: how can i draw the windows 200(for exemple) button face(with normal states)?
(my objective is showing the button and then draw the image and text)

I'm not sure I understand the question -

Are you now using a BS_OWNERDRAW style?
Are you trying to draw on the control and nothing is happenning?

yes.. i'm using the BS_OWNERDRAW style and i can draw things.
my problem is: can i draw the windows 2000 button visual style?(for not recreate the button)

that you can specify to get a "classic" style OWNERDRAW button, if that is what you you are asking.

The "classic" button frame uses two different color lines along the left and top edges, and two different
color lines along the right and bottom edges. (the frame is two pixels thick). So you would have to draw
these lines yourself.

now i can share the code:

Code:

#include <windows.h>

#include <Uxtheme.h> //for use the theme functions
#include <Vsstyle.h> //for use the BP_PUSHBUTTON or others const's
#include "Untitled2.h" //is for resource file

    }
    return DefWindowProc (hwnd, iMsg, wParam, lParam) ;

i only see 1 problem: is showed the button face with windows xp visual style, instead windows 2000 visual style
what you can tell me?
(you can test my code, just delete the '#include "Untitled2.h"'(5 line) and change these 'wndclass.hIcon = LoadIcon (NULL, "IDI_ICON");'(24 line))

I tried running your code, but my compiler (Pelles) does not like two of the functions:

OpenThemeData
DrawThemeBackground

Are you using XP with the theme set to XP?
If so, that is why you are getting XP button style frames, I believe.
I don't see anything in your code that explicitly specifies a classic style.
You can confirm that by changing the desktop theme to classic and running the program again.

and how i can convert to the classic them?(i'm totaly new with these code)
another important thing: if i use the ownerdraw style, why i lose(isn't activated when i click on button) the WM_COMMAND message?

You can right click on the desktop to get the display properties dialog. Then you can change the theme
there in the "Themes" section. Or you can select "Display" in the control panel to get the same dialog.
This changes the theme for all windows.

You need an ID value for the window. For example,

#define ID_MYBUTTON 1

//create the button
hButton=CreateWindowEx (0,"button", "H&ello \nmy mother",
WS_CHILD | WS_VISIBLE | BS_OWNERDRAW | BS_NOTIFY,
100, 100,100, 50,hwnd, (HMENU) ID_MYBUTTON, hInstance, 0) ;

Then check for ID_MYBUTTON in the wParam for the WM_COMMAND message.
