Colored Text staying

[SteveCRM]

in WM_COLORBTN I am using this code


if(bmatrix[fx][fy]=="green")
{
SetTextColor((HDC)wParam, RGB(0, 255, 0));
SetBkMode((HDC)wParam, TRANSPARENT);
GetClientRect((HWND)lParam, &rt);
DrawText((HDC)wParam, TEXT("hello"), -1, &rt, DT_SINGLELINE | DT_VCENTER | DT_CENTER);
return (long)hBrush2;
}
(sorry about the alignment)

it works ok, but whenever I push other buttons on my screen, it goes away, and doesn't come back, is there any way to make the text permanent? :confused:

you need to use the WM_CTLCOLORBTN


case WM_CTLCOLORBTN:
// Change the Button control background color
// Ref.
// wParam - handle to static control DC (HDC)
// lParam - handle to static control handle (HWND)

// Set the return value
return (long)hBrush;

Im sorry i typed wrong, I am using WM_CTLCOLORBTN

Im using it in a game of memory, and I must make it using colors (matching "Yellow" to a yellow button) if you need a better understand of what i'm trying to accomplish.

here is my full segment of code
bmatrix holds all the information for a memroy game
board is the actual matrix of buttons used in the game
I'm using apstring (don't kill me)

case WM_CTLCOLORBTN:
// Change the Button control background color
// Ref.
// wParam - handle to static control DC (HDC)
// lParam - handle to static control handle (HWND)
for(fy=0; fy<2; fy++)
{
for(fx=0; fx<5; fx++)
{
if ((HWND)lParam == board[fx][fy])
{
if(bmatrix[fx][fy]=="green")
{
SetBkColor((HDC)wParam, RGB(0,255,0));
GetClientRect((HWND)lParam, &rt);
DrawText((HDC)wParam, TEXT(" "), -1, &rt, DT_SINGLELINE | DT_VCENTER | DT_CENTER);
return (long)hBrush2;
}
if(bmatrix[fx][fy]=="red")
{
SetBkColor((HDC)wParam, RGB(255,0,0));
GetClientRect((HWND)lParam, &rt);
DrawText((HDC)wParam, TEXT(" "), -1, &rt, DT_SINGLELINE | DT_VCENTER | DT_CENTER);
return (long)hBrush2;
}
if(bmatrix[fx][fy]=="blue")
{
SetBkColor((HDC)wParam, RGB(0,0,255));
GetClientRect((HWND)lParam, &rt);
DrawText((HDC)wParam, TEXT(" "), -1, &rt, DT_SINGLELINE | DT_VCENTER | DT_CENTER);
return (long)hBrush2;
}
if(bmatrix[fx][fy]=="yellow")
{
SetBkColor((HDC)wParam, RGB(255,255,0));
GetClientRect((HWND)lParam, &rt);
DrawText((HDC)wParam, TEXT(" "), -1, &rt, DT_SINGLELINE | DT_VCENTER | DT_CENTER);
return (long)hBrush2;
}
if(bmatrix[fx][fy]=="cyan")
{
SetBkColor((HDC)wParam, RGB(0,255,255));
GetClientRect((HWND)lParam, &rt);
DrawText((HDC)wParam, TEXT(" "), -1, &rt, DT_SINGLELINE | DT_VCENTER | DT_CENTER);
return (long)hBrush2;
}
}
}
}
return 0;



again im sorry about alignment

it shows up briefly, and stays if I hold the mouse button down...but won't stay :confused:

I fear you'll have to subclass the buttons and catch the WM_PAINT message. Don't forget to let the button draw first (by calling CallWndProc), and only then you draw what you want.

[SteveCRM]

err...sorry but i really have no idea how to do that...:( no other way? im guessing there isn't really a way of putting that in a loop until another button is pushed. I don't really care if its crap code or anything, but as long as color comes up on a button :) Do you think i'm going about it with a wrong method? or would this definately be easiest?

[CornedBee]

I think it's the only way. You see, a button doesn't want anyone to draw on it's surface.

You could use ownerdraw buttons. But then you loose the typical button look.

[Chris]

but you still can have 2 bitmap which act as a base image for you owner draw button and this image will having the typical button look.

Although this seen a lot of work, but it still archieve your goal :)
