onMouse Over for groupBox 1

[bubak]

I'm using groupBox to show an area in my prog, and I need to show the cursor position in it. I want to use sth like onMouseMove, but groupBox has just BNClicked and BNDblClicked msgs. How do I do that pls?
thx

You want to use a feature that is not by default implemented
by MFC framework

Try to add by hand a line like:
ON_MESSAGE(WM_MOUSEMOVE,OnMyMouseMove) inside your BEGIN_MESSAGE_MAP

also put a function like
void OnMyMouseMove() or
void OnMyMouseMove(WPARAM wParam, LPARAM lParam)
in your cpp

and a line like:
afxmsg void OnMyMouseMove() in the DECLARE_MESSAGE_MAP from your .h file

I am not very sure if it works, but maybe you will have a start point.

Hope this helps, s-)

I've done it this way:
I created OnMOuseMove for my app, and a dataRect structure, that is initializes in OnInit :
GetDlgItem(IDC_DATA)->GetWindowRect(dataRect);
in OnMouseMove :
POINT p;
GetCursorPos(&p);
if(PtInRect(dataRect,p))
{
SetDlgItemText(IDC_ActTime,"IN"
}else
{
SetDlgItemText(IDC_ActTime,"out"
}
Everything works ok( in and out), until I move tha window. I though, that it chcecks still the old dataRect and I've moved GetDlgItem(IDC_DATA)->GetWindowRect(dataRect); int onPaint(), but it doesn't help. It stills chceks the first position of dataRect. Why?

Because GetCursorPos() reads the coordinates relative to the screen ,not to the window.

Use a CPoint instead of POINT and offset it with the coordinates of the upperleft corner of your dlg.

To read the Rect of the dialog use

CRect rcDialog;
GetWindowRect(&rcDialog);

Hope this helps, s-)

yep, i know, but when I do GetWindoRect, I'll get upper left and bottom right point of my dialog and this will be also relative to screen, so I can do just GetCursorPos and PtInRect and it should work fine, i think. but it does not. ;-(

ANOTHER ONE BIG QUESTION ;-)
I have an groupbox IDC_DATAQ, and CRect dataRect.
When I do
GetDlgItem(IDC_DATA)->GetWindowRect(dataRect);
in OnInitDIalog, in dataRect will be values relative to dialog border, but when I do it in OnPaint(), the values in dataRect will be relative to screen. Why?

It is because probably the compiler somehow uses once the GetWindowRect from SDK(even if this takes 2 parameters as I remembewr) and another time the GetWindowRect of the CWnd class.

I didn't try what you say but to better why don't you qualify your functions with :: for the sdk and with this->for the CWnd ones and see what happens.

Also use the two API and CWnd functions
ClientToScreen and ScreenToClient.

Hopet his helps,
