i build function to remove in the class

class HWld : public WithmeuL<TopWindow> {
private:
void fxRemove();
int keyId;
public:
typedef HWld CLASSNAME;
.......................
void HWld::fxRemove(){
int i = grid.GetCursor();
String s;
s << i;
PromptOK( s );
grid.Remove( i );

}
....................... below in constructor compilation error occurs
main.cpp (86): error: 'this' cannot be implicitly captured in this context

HWld::HWld()

{

CtrlLayout(*this, "Titulo da janela");
keyId = Ctrl::RegisterSystemHotKey(K_CTRL_DELETE, []{ fxRemove(); } );

I had done a simple test before with:

int id = Ctrl::RegisterSystemHotKey(K_CTRL_DELETE, [] { PromptOK("Ctrl delete ok"); });

it didn't generate an error, I thought I could put a function in place of the promptOK
so how should i write the code?

there is probably another alternative using a WhenAction but I don't know how to write this option.

Thanks

i found a solution that worked, replacing the lambda function
and it was like this:
keyId = Ctrl :: RegisterSystemHotKey (K_CTRL_DELETE, THISBACK (fxRemove));

but I haven't figured out how to do it using WhenAction.
