Add Tabs at Runtime

[joerg-rade]

Hi Robert,

I would like to add tabs to TabPanel at runtime. Showcase.start() and TabPanel.addTab() suggest that this is not possible right now.

SubClassing didn't work out since TabPanel.content & nav are private.
How should I proceed?

Thanks in advance
Jörg

It's definitely possible to add tabs at runtime. This code is working without any problems for me:

        val panel = tabPanel {
            addTab(tr("Blue panel"), Tag(TAG.DIV, " ", rich = true) {
                background = Background(Col.BLUE)
                height = 40.px
            })
            addTab(tr("Green panel"), Tag(TAG.DIV, " ", rich = true) {
                background = Background(Col.GREEN)
                height = 40.px
            })
        }
        var counter = 3
        button("add new tab").onClick {
            panel.addTab("Tab $counter", Tag(TAG.DIV) {
                label("Any dynamic content of tab number ${counter++}")
            })
        }

Thanks - it works.
I don't know anymore where I got lost ;-)

A sample where creating and adding the tab object to the panel are split in two steps could help newbies like me.
