Hi,

I'm still having some problems. Crying or Very Sad

I added the typedef but I still get compile errors. Here is the code:

void CounterCtrl::Inc()
{
number++;
Refresh();
}

void CounterCtrl::InitTimer(int seconds)
{
SetTimeCallback(THISBACK(CounterCtrl::Inc), -1000, 33);
}

Value CounterCtrl::GetData() const
{
return number;
}

void CounterCtrl::SetData(const Value& v)
{
number = v;
Refresh();
}

void CounterCtrl::Paint(Draw& w)
{
Size sz = GetSize();
w.DrawRect(sz, paper);
String txt = AsString(number);
sz = (sz - w.GetTextSize(txt, font)) / 2;
w.DrawText(sz.cx, sz.cy, txt, font, ink);
}

/***
void CounterCtrl::LeftDown(Point, dword)
{
number++;
Refresh();
}
***/

CounterCtrl::CounterCtrl()
{
number = 0;
ink = SBlack;
paper = SWhite;
font = StdFont();
SetFrame(BlackFrame());
}

CounterCtrl::~CounterCtrl() {}

Notice how I disabled LeftDown() callback? I wanted to replace it with the Inc() method which gets called at preset intervals by calling the InitTimer() method. When I compile this I get the ff errors:

C:\MyApps\Counter\Counter.cpp: In member function `void CounterCtrl::InitTimer(int)':
C:\MyApps\Counter\Counter.cpp:16: error: invalid conversion from `int' to `_CNULL'
C:\MyApps\Counter\Counter.cpp:16: error: initializing argument 1 of `Callback::Callback(_CNULL)'
Exitcode: 1
compiled in (0:10.53)
1 file(s) compiled in (0:10.53) 10531 msec/file

There were errors. (0:14.82)

I am thinking the typedef required a specific method signature as input? Can you point me to the right direction? Thanks.

regards
