Re: Simple drawing application fails
I have a simple application where I draw som lines and circles in two
funtions called by the OnPaint(). However it fails. One function draws an
'X' and the other 'O' in the ClientDc. The problem is that I only get som '/'
instead of an 'X' when drawing an 'X'?
Does this has something to do with which device context I use? In the
turorial I have the onPaint handler uses the CPaintDc dc and passes the dc as
a pointer to the functions meanwhile in my code I use the CClientDC locally
in the function?
This is my pseudo code:
CClientDC dc (this);
CRect rect = aRect[cellNbr];
pOldPen = dc.SelectObject(&pen);
The way you are doing it is a disaster. It causes an endless loop of
OnPaint _must_ use CPaintDC. This is elementary lesson 1 in painting
