Drawing on layers ... or not

With the following code:

function DrawStuff(string gname, string layer, variable isChecked)
    if(isChecked)
        SetDrawLayer/W=$gname $layer
        DrawText 0.2,0.2,"stuff drawn!"
    else
        SetDrawLayer/W=$gname/K $layer
    endif
end

I can do:

•display
•DrawStuff("Graph0", "ProgBack", 1)
•DrawStuff("Graph0", "ProgBack", 0)

Text will first appear on Graph0, and the last line will take it off. So far so good.

Then I use

function doPanel(string win)
    NewPanel/N=ctrlPanel/W=(0,0,100,100) /EXT=0/HOST=$win
    CheckBox checkGrid, win=ctrlPanel, pos={15,25},size={61.00,16.00},proc=myCheckProc
    CheckBox checkGrid,win=ctrlPanel,title="draw stuff",value=0
end

Function myCheckProc(cba) : CheckBoxControl
    STRUCT WMCheckboxAction &cba
   
    string HostName, cmd
    string layer = "ProgBack"
   
    switch( cba.eventCode )
        case 2: // mouse up
            HostName = StringFromList(0,cba.win,"#")
            sprintf cmd "DrawStuff(\"%s\", \"%s\", %g)", HostName, layer, cba.checked
            print cmd
            drawStuff(HostName, layer, cba.Checked)
            break
        case -1: // control being killed
            break
    endswitch

    return 0
End

and add a sub-window to "Graph0":

doPanel("Graph0")

Now clicking the "draw stuff" checkbox should cause the same as the commands above, but nothing is drawn, at least not on my system, which is:

print IgorInfo(3)
  OS:macOS;OSVERSION:10.15.7;LOCALE:US;IGORFILEVERSION:9.01B01;

I might be missing something but I just don't seen it. Maybe sub-window syntax?

Solved!

I forgot to add /W=$gname to DrawText in the top function.

D'Oh!

 

EDIT:

Why is that? One looks since more than a day for the error and as soon it has been posted it jumps right into the face!

Well, either way, the forum proofs to be extraordinary useful!

Probably better that way than being caught by colleagues speaking to a duck!

Perhaps in the debugger there should be a little rubber duck picture with the caption "Talk to me"
