IconButton
/IconToggle
'ssetDisabled
wasn't really working, so I tried implementing it.After considering several approaches, I chose the implementation that does not instantiate
MDCIconButtonToggle
frommdc-icon-button
and uses the button element placed as a child node.Since I have set the style of mdc-icon-button to
display:contents;
, the wrapper has no visual effect and does not affect the layout.This change may cause a problem that style is not applied as expected when setting style for
IconButton
/IconToggle
using child combinator or sibling combinator in CSS. Someone may need to modify CSS.The most ideal approach to the problem is to extend
HTMLButtonElement
, but even the latest elm didn't support custom elements that extend the built-in element. (elm/virtual-dom#156)I think there are other implementations besides my code, but some compromise will be required anyway.
