    oh ok, I need to head out now 😦 but thanks for help will take another look without the paint event
  • s
    did I get drowned out by Nanjizal 😅
  • s
    I just want to open a webpage on double click, which it does, but it opens twice
  • s
    Copy code
    hx
@:bind(this, MouseEvent.DBL_CLICK)
    private function doShowSource(me:MouseEvent) {
        if (me.target != this)
            return;
        if (mod.git_path == null)
            return;
        me.bubble = false;
        switch (Sys.systemName()) {
            case "Windows": 
                Sys.command("start", ['https://github.com/${mod.git_path}']);
            case "Mac": 
                Sys.command("open", ['https://github.com/${mod.git_path}']);
            case "Linux": 
                Sys.command("xdg-open", ['https://github.com/${mod.git_path}']);
        }
    }

    doing like 
    xdg-open http://haxeui.org/explorer/
    only opens once so it's a code problem
  • b
    smells like a bug... ill check it out
  • s
    can I detect windows dark theme? I looked it up and I really don't want to have to access registry keys lol
  • s
    looks like wxWidgets users are at a loss as well 😶
  • b
    i cant repro this end, you sure you dont have other handlers on it or something? If you add a trace there it gets called twice?
  • b
    and if you do get two traces, what about throwing an exception on the 2nd invocation to see the stack?
  • s
    the item has a lot of children
  • s
    I could be clicking on the spacer
  • b
    interesting, lemme try and add a box in the box and see what that does
  • b
    yeah, as expected, i only get the double click (or click) on the box i added the listener to
  • b
    so that seems right too
  • s
    this is the xml
  • b
    yeah, that seems fine... if you add a trace in the listener does it get printed out twice?
  • b
    and if it does can you throw an exception on the second one to see the stack trace
  • s
    gets printed twice
  • b
    weird
  • s
    how would I throw on second invocation
  • b
    add a member var: 
    var temp = 0
    and then in the function:
    Copy code
    haxe
if (temp > 0) throw "foo";
temp++;
  • b
    you'll need to build the app in debug to get the stack
  • b
    what OS is this?
  • s
    wait what debug flag do I use??
  • s
    this is linux qt
  • b
    haxe something.hxml debug
    (i think)
  • b
    is double click "a thing" on your OS?
  • b
    > On the other hand, X apparently has no double click (the WM does): https://github.com/glfw/glfw/issues/462 so.. yeah. We're left with: > > 1. New event type, native but not toggleable on Windows, must be 'emulated' on Linux, also no triple or quadruple click > 2. Just provide a getDoubleclickTime function to wrap the Windows one, on Linux return some sane value > 3. 'Emulated' everywhere via a count field on all with user defined time or 'native' time on Windows if SFML user didn't set any > 4. Do nothing ;D

    > Just adding some more details on why it's non-trivial to implement on X11, for anyone who finds their way here. > > Double-click delay is saved per major version per toolkit (because these things tend to change over time), meaning GLFW would have to figure out the toolkit and version used by the desktop environment (where there is a desktop environment in the first place and it uses only a single major version of a single toolkit) and then do toolkit-, version- and possibly desktop system-specific things to read the proper double-click delay. > > The alternative would be to pick an arbitrary double-click time for X11 and have people wonder why GLFW applications ignore the user's settings there, or implement it manually on all platforms, at which point it's far less useful and might as well be implemented the application anyway.
