autohotkeys expression not evaluating -

-

i have simple autohotkeys macro test if window active. if it's active, want stop until window becomes inactive , re-activated again.

the problem test whether window inactive not working. here code:

^w:: ;hotkey fires   done = false  settimer, checkpopups, 10000    ; check every 10 seconds annoying popup  checkpopups:   if ( winactive("volume spike - down") )   { ;specific lines when active window true msgbox (%done%) if (!done) {   msgbox hello   done := true   } }  ifwinnotactive volume spike - down { done = false msgbox not }  return

when runs, first message box indicating state of done (which false @ beginning). (!done) not evaluate true , second message box (hello) not fired. idea wrong here?

autohotkey conceives true / false-boolean expressions 1 / 0. if you, wouldn't use former keywords @ all.

but still, can, have change initialisation to

done := false

(store expression). done = false same done := "false" (string assignment). afaik, change to

done = %false%

i know it's possible change color of rubber band rectangle way: qrubberband rubberband = new qrubberband(qrubberband::rectangle, this); qpalette pal; pal.setbrush(qpalette::highlight, qbrush(qt::white)); rubberband->setpalette(pal); but here way achieve rubber band, rendered qgraphicsview when rubberbanddrag mode active? or in "global scope"? i'm sorry wrote question, i've looked solution long time, , nothing. few minutes after asking, found solution setting stylesheet. i'm sharing it. just go designer of qt creator, click on canvas (qgraphicsview). in "qwidget" part find "stylesheet", edit it, , put like: selection-background-color: rgba(255, 255, 255, 128); that's :-). thanks.
