    i was thrown off by the fact that the font is different than the first listview
  • b
    thats because that is a native qt list
  • b
    which im guessing hooks into the winapi
  • b
    i guess that uses win32 listctrl
  • b
    yeah
  • b
    yeah, i defo remember when i was PoC'ing it going "right, this is the 'the one'", then i started getting crashes, not all the time, but with things like: having slots assigned for keypresses in a textfield, and then pressing lots of keys

    ... and this happend in hxQt (not haxeui-qt) so it indicates my externs and wrappers were badly written
  • b
    i feel like ive learned alot more about hxcpp since then (maybe not), so maybe ill have another stab at "non seg fault externs" at some point... maybe even just fresh eyes would help
  • b
    either way, it would be super nice... and it should be achievable

    1. I take it it's not acceptable to have multiple component with the same ID? And 2. If not, how best to assign unique IDs when creating multiples of the same component at runtime?
  • r
    (eg, I have a tab view which I'm adding and removing tabs to and from. The contents of each tab is an instance of the same component, but getting its data from a different source)
  • r
    Ah... maybe that's not the issue? Is there a problem with removing a tab from a tabview when that tab isn't currently selected?
  • r
    The tab with the box's text element stays there and I get 
    WARNING: trying to remove a child that is not a child of this component
  • r
    Is that possibly because it's trying to remove what's inside the tab when it's not being rendered? (I should maybe switch to the tab forcibly then remove it?)
  • r
    (haxeui-heaps, git, if it helps)
  • b
    that tabs one sounds like a bug, do you have a minimal repro?
  • b
    As for the unique ids, it might be better to make custom views out of the pages
  • b
    then the variables will be at the class level and therefore "safe" (i think)
  • b
    eg:
    Copy code
    xml
<tabview>
    <my-special-page source="foo" />
    <my-special-page source="bar" />
</tabview>
  • b
    ok, i get that warning, but the page is removed... how are you removing the page? 
    TabView.removePage(...)
    ?
  • b
    right, warning should be fixed now in git haxeui-core
  • b
    but it was "fine" in the sense it was doing what it was supposed to, ie, removing the tab, etc... the warning was also technically valid since it was trying to remove the page from the tabview content and, as you mentioned, it hadnt been added yet - so it wasnt technically a child
  • b
    hello, where should i look for documentation about theme handling ?
  • b
    in what sense? About how to write themes? Or how to set them up?
  • b
    themes are just css files, so you can setup them here: https://github.com/haxeui/haxeui-guides/blob/master/modules.md#themes
  • b
    ie, using a module.xml
  • b
    as for writing themes, you are better off just looking at the default themes
  • b
  • b
  • b
    but you can do quite alot more than the default theme does ofc
