argument or method to assign icons and tooltips to tabs

[landroni]

As per http://stackoverflow.com/questions/24706434/how-to-assign-icons-to-gnotebook-tabs/24741832#24741832 , I was wondering if there should be gnotebook() argument or method to assign icons to tabs.

The following function can do this:

add_stock_icon <- function(nb, nm, page, left=TRUE){
    child <- nb$widget$getNthPage(page-1)
    box <- nb$widget$getTabLabel(child)
    icon <- gimage(stock.id=nm)
    box$packStart(icon$widget$parent)
    if(left) box$reorderChild(icon$widget$parent, 0)
}

Should there be something similar included in gWidgets2?

I'd like this, but I'm not sure I can make it multiplatform and am pretty sure I can't get it to accept an event, which would make things like a close button possible. I can add it as a private method for gWidgets2RGtk2 though (so that nb$add_tab_icon(page, nm, left) could be called.)

[landroni]

Until this can be made multiplatform, I think a private method for gWidgets2RGtk2 would be nice.

I just checked something in to gWidgets2RGtk2 (add_tab_icon). Let me know if it doesn't work.

Perfect!

I also added a tooltip argument here.

Works great. My only concern is: what if you want to add a tooltip, but no icon. Perhaps a separate add_tab_tooltip would be more intuitive?

[jverzani]

Okay, good point. Just added add_tab_tooltip to gWidgets2RGtk2. Thanks.

There is an issue: "Error in ntbk$add_tab_tooltip(1, "Filter data frame and display subset") : object 'evb' not found"

I suspect the missing bit is evb <- icon$widget$parent, or similar.

[jverzani]

Sorry, fixed now. If you add the icon after the tooltip, only the label will get the tooltip.
