Not a signal or slot declaration: ??

[Anonymous_Banned275]

What am I doing wrong ( this time ) ?

Here is the complaint

/mnt/sde5/QT_PROGRAMS_FULL/MDI_BT/MDI_BT/SUB_FT857/mainwindow_sub_ft857.h:130: Error: Not a signal or slot declaration

and here is the source of the error

public slots:
void static SCANStarted(void);

Hope it is not the "static" keyword messing things up.
Requested by compiler for yet unknown reason - hopefully not the source of he error and to be investigated lalter.
Cheers

,,,just the facts ma'am..

a slot can not be static.

@Christian-Ehrlicher said in Not a signal or slot declaration: ??:

a slot can not be static.

hence how do I fix this ?

Use e.g. a lambda - already told and shown you multiple times.

@AnneRanch
Depends what class this is and what class the SCANStarted slot is in.

Maybe @Christian-Ehrlicher already knows those, I don't.

Your connect statement should be (add the class to the slot):

connect(watcher, &QFutureWatcher<int>::started, this, &MainWindow_SUB_FT857::SCANStarted);
