[R-gui] Post hoc tweeking of ggenericwidget?

[christiaan pauw]

Thanks John

I have tried another approach after reading your advice. I followed
the example in the traitr vignette and included ggenericwidget inside
a traitr dialog together with a gvarbrowser object. Now you can drop
objects from the wordkspace browser (because in practice I always
froget or misspel something). All that is needed to implement this for
another function is varying the second last line.

regards
Christiaan

require(traitr)
options("guiToolkit"="RGtk2")

tt=stats:::t.test.default

d.dlg <- aDialog(items=list(),
title="generic dialog",
help_string="You're on your own here. Good night and good luck",
buttons=NULL
)

g=aGroup(attr=list(size=c(500,500)))
g2=aGroup()

g.view <- aGroup(
aContainer(
aFrame(aContainer(g2),label="Write var name or drop var for x")
),
aFrame(aContainer(g),label="Workspace Browser")
,horizontal=TRUE)
	
d.dlg$make_gui(gui_layout=g.view,visible=FALSE)

varbrowser <- gvarbrowser(cont=g$container)
tt.w <- ggenericwidget(tt,cont=g2$container)

d.dlg$visible(TRUE)
