I am making changes to recent clone, trying to add mask support...

I added some new options to support unmodified pcb2gcode backend...
Backtrack, invert-gerbers, path-finding-limit and some crude solder mask generation.
I know that the mask generated also mills above the tracks, but tinning these tracks would fix this.
( limitation of the backend?)

These cloned options are handled by the mask creation button
without manually messing with milling --zwork, --invert-gerbers, and --extra-passes options.

The problem i am having is in mainwindow.cpp

Added line 159:
connect(ui->maskstartPushButton, SIGNAL(clicked()), this, SLOT(maskstartPcb2gcode()));

at around line 577 i added:
`void MainWindow::maskstartPcb2gcode()
{
QStringList arguments;

args[ MILLARGS ].insert("zwork", ui->maskzworkDoubleSpinBox);
args[ MILLARGS ].insert("invert-gerbers", = true; // <-- how to fix this so it is true without checkbox?
args[ MILLARGS ].insert("extra-passes", ui->maskextrapassesSpinBox);

MainWindow::startPcb2gcode();

}
`
I thought that these args would not get used until the mask start button would get clicked?
but these values override the --zwork --invert-gerbers and --extra-passes from normal milling when starting the program.
( I looked at 'show command line arguments' as well, and it looks like these get clobbered as well )
I am not a wiz when it comes to C++ / QT, but have some small 8051 C experience on some embedded from many years ago.
Can someone here give me pointers on what is going on here?

@Efudd-byte

did you mean:

`void MainWindow::maskstartPcb2gcode()

or:

void MainWindow::maskstartPcb2gcode()

Also seems like you have mis mached brackets in your line 159 )
