    functional test

    I'll figure out how to center the cards in the hbox later
  • b
    Thank you for all the help. I'm going to sleep on it from here, deal with my day job, and come back to this tomorrow.
  • b
    np - good luck - let me / us know of progress when you have something perdy 🙂
  • c
    i ideally want a backend-agnostic way of doing it, but for now, just an improvement for doing it in hxWidgets is better than nothing
  • c
    eventually i would love it if haxeui had an interface for it (if i could help trying to implement it, i would be happy to), but for now, the code only works with hxWidgets anyway
  • b
    can you paste some test code for the RGBA image, then i can fix hxwidgets (the .imageData part)
  • b
    i dont really have time to create a project etc, so a test app would be useful 🙂

    thanks

    OK, so latest git version of hxWidgets has some helpers now, namely 
    Image::hasAlpha
    , 
    Image::addAlphaChannel
    , 
    Image::ImageData::copyRGB
    , 
    Image::ImageData::copyRGBA
    , 
    Image::ImageData::copyARGB
    . To use it in your app, you have to jump through quite alot of hoops (its the nature of wx) and you are basically sidestepping haxeui at this point:
    Copy code
    haxe
    public override function onReady() { // make sure to use in onReady since the native wxWindow might not have been created in constructor
        super.onReady();
        final argbdata = convertARGB(haxe.Resource.getBytes("data")); 
        var image = new hx.widgets.Image(200, 56, true); // last param creates alpha channel (false by default) - image.addAlphaChannel() would also work
        image.imageData.copyARGB(argbdata); // copy raw bytes in wx bytes buffer
        thumb.width = 200; // must set size now, since we are subverting haxeui so it has no concept of the size
        thumb.height = 56;
        var thumbWindow = cast(thumb.window, hx.widgets.StaticBitmap); // grab the static bitmap window (what wx uses to display bitmaps)
        thumbWindow.bitmap = new hx.widgets.Bitmap(image); // use the created wxImage to set the wxStaticBitmaps bitmap property
    }

    i might add a 
    ToolkitAssets.instance.imageFromRaw(someBytes, Format.RGBA, ...)
    - that would wrap up alot of that, but its pretty low priority at the moment
  • b
    oh, actually, you can simplify that a little (and not side step haxeui so much), i forgot that 
    typedef ImageData = hx.widgets.Bitmap;
    , so with that in mind:
    Copy code
    haxe
    public override function onReady() { // make sure to use in onReady since the native wxWindow might not have been created in constructor
        super.onReady();
        final argbdata = convertARGB(haxe.Resource.getBytes("data")); 
        var image = new hx.widgets.Image(200, 56, true); // last param creates alpha channel (false by default) - image.addAlphaChannel() would also work
        image.imageData.copyARGB(argbdata); // copy raw bytes in wx bytes buffer
        thumb.resource = new hx.widgets.Bitmap(image);
    }
  • b
    (you can also have that in the constructor now - rather than onReady - if you want since you arent accessing the 
    .window
    directly, so haxeui can control things like that correctly)
  • c
    ooh, very nice
  • c
    ToolkitAssets.instance.imageFromRaw would be very handy to wrap it up nicely - can i perhaps try helping implement it? is there anything i can do for other platforms?
  • c
    as you might guess, i have (some) experience working with raw image data, so i might be able to help
  • b
    its mainly about seeing how the other backends work with raw rgba data, although to be fair, the way the backend calls system works, you dont really have to implement anything you dont want to: 
    ToolkitAssets (core) extends AssetsImpl (backend) extends AssetsBase (core)
    - so i could just add an empty / stub imageFromRaw in the base, then override it the impl that exists in haxeui-hxwidgets and simply ignore it in other backends (for now) and then take them on a case by case basis
  • b
    ill have a think about it and will maybe do that over the weekend
  • c
    ok
  • c
    i would imagine that most backends will have a way to work with raw rgba data directly
  • c
    with the possible exception of pdcurses
  • b
    yeah, i would have thought so... width, height, bytes and format i would have expected has pretty much every backend covered
  • b
    Okay, new question, given this example, how would I make the label wordwrap to a new line if it exceeds the width of the card? http://haxeui.org/builder/?qgqljx
  • b
    label.percentWidth = 100
  • b
    well that's simple
  • b
    🙂

    I'm still very new to haxe. Primarily a Python programmer here, so the lack of comprehensive autofill and deep analysis is hitting hard
  • c
    i find it's a bit intimidating for newbies
  • c
    the documentation is unfortunately a little lacking
