Can I have a DropDown with image?

dropDown(tr("Dropdown with custom list"), icon = "far fa-image", style = ButtonStyle.WARNING) {
    minWidth = 250.px
    image(require("img/cat.jpg")) { height = 170.px; margin = 10.px; title = "Cat" }
    separator()
    image(require("img/dog.jpg")) { height = 170.px; margin = 10.px; title = "Dog" }
}

suggests I can have either a FontAwesome icon plus text or an image.
What I want is a custom image with text.

You mean on the button or on the list ?

[Jörg Rade]

On the list and on the button.
I would like to replace the "Three Objects" FA icon with an Image as well have text right of the coulored gif + regular menu item behaviour, i.e. elicit an event on click.

kroviz can connect to two or more different servers at the same time. Each serverApp may have its own icon etc. I want to provide the user with visual feedback, which serverApp is in the 'foreground' and allow to switch between them.

[Robert Jaros]

to use image instead of icon for the button of the DropDown component just use image property (it's there, it's just not exposed in the constructor)

[Jörg Rade]

Thanks - I'll try (thought I already did ...)

[Jörg Rade]

The following code comes pretty close:

fun insertConnection() {
    mainEntry.separator()
    val resString = io.kvision.require("img/gift_48.png")
    val menuEntry = buildMenuEntryWithImage("Connection 1", image = resString, { LoginPrompt().open() })
    mainEntry.add(menuEntry)
}

private fun buildMenuEntryWithImage(label: String, image: ResString?, action: dynamic): Link {
    val link = Link(label, image = image, className = "dropdown-item")
    link.onClick { e ->
        val at = Point(e.pageX.toInt(), e.pageY.toInt())
        UiManager.position = at
        action()
    }
    return link
}

Can I scale the image (ResString) down?

[Robert Jaros]

Only with some css I'm afraid.

[Jörg Rade]

OK - no problem (I don't fear CSS anymore ;))

[Jörg Rade]

Thanks a lot for your help!

[Robert Jaros]

you can use Style object for this with pure kotlin 😉

[Jörg Rade]

resString.style doesn't suggest anythin in IJ ...

[Jörg Rade]

I got it:

val resString = io.kvision.require("img/gift_48.png") {style}

[Jörg Rade]

Have a nice day and stay healthy!

[Robert Jaros]

I was talking about:

val myStyle = style(".dropdown-item") {
    style("img") {
        width = 20.px
        height = 20.px
    }
}

[Jörg Rade]

I arrived at:

[Jörg Rade]

val resString = require("img/gift_48.png")
resString { addCssClass("app-icon") }

[Jörg Rade]

but it doesn't work - I'll follow your suggestion, though
