I am trying to draw a gray rectangle on a bw display.
I thing I have to use the WinSetPattern and WinFillRectangle
functions.
At first I get the current pattern, then set mine, fill the rectangle,
and finally set the original.
But when I am trying to build the program, GCC sends me the
warning message:
warning: passing arg 1 of 'WinSetPattern' from incompatible pointer
type
What is the problem? Can anybody help me? It is just a warning
message, the rectangle is ok, but the warning message is always
coming...
Thanks,
Emil
Here is something like my code:
// declaration of pattern variables:
CustomPatternType OriginalPattern;
CustomPatternType MyPattern = { 0x55, 0xAA, 0x55, 0xAA,
0x55, 0xAA, 0x55, 0xAA };
...
WinPushDrawState();
...
// setting the rectangle r's values
WinGetPattern ( &OriginalPattern );
WinSetPattern ( &MyPattern );
WinFillRectangle ( &r, 0 );
WinSetPattern ( &OriginalPattern );
