Examples

## Not run: 
## These cannot be run by examples() but should be OK when pasted
## into an interactive R session with the tcltk package loaded

### A tk2notebook example
tt2 <- tktoplevel()
nb <- tk2notebook(tt2, tabs = c("Test", "Button"))
tkpack(nb, fill = "both", expand = 1)
tb1 <- tk2notetab(nb, "Test")
lab <- tk2label(tb1, text = "Nothing here.")
tkpack(lab)
tb2 <- tk2notetab(nb, "Button")
but <- tk2button(tb2, text = "Click me", command = function() tkdestroy(tt2))
tkgrid(but)
tk2notetab.select(nb, "Button")
tk2notetab.text(nb) # Text of the currently selected tab

## A simple tk2panedwindow example
tt2 <- tktoplevel()
pw <- tk2panedwindow(tt2, orient = "vertical")
lpw.1 <- tk2text(pw)
lpw.2 <- tk2text(pw)
tkadd(pw, lpw.1)#, minsize = 100)
tkadd(pw, lpw.2)#, minsize = 70)
but <- tk2button(tt2, text = "OK", width = 10,
    command = function() tkdestroy(tt2))
tkpack(pw, fill = "both", expand = "yes")
tkpack(but)
# Resize the window and move the panel separator with the mouse

## A tk2combobox example
tt2 <- tktoplevel()
cb <- tk2combobox(tt2)
tkgrid(cb)
# Fill the combobox list
fruits <- c("Apple", "Orange", "Banana")
tk2list.set(cb, fruits)
tk2list.insert(cb, "end", "Scoubidou", "Pear")
tk2list.delete(cb, 3)   # 0-based index!
tk2list.size(cb)
tk2list.get(cb)   # All items
# Link current selection to a variable
Fruit <- tclVar("Pear")
tkconfigure(cb, textvariable = Fruit)
# Create a button to get the content of the combobox
but <- tk2button(tt2, text = "OK", width = 10,
    command = function() {tkdestroy(tt2); cat(tclvalue(Fruit), "\n")})
tkgrid(but)

### An example of a tk2spinbox widget
tt2 <- tktoplevel()
tspin <- tk2spinbox(tt2, from = 2, to = 20, increment = 2)
tkgrid(tspin)
## This widget is not added yet into tcltk2!
#tdial <- tk2dial(tt2, from = 0, to = 20, resolution = 0.5, width = 70,
#       tickinterval = 2)
#tkgrid(tdial)
tbut <- tk2button(tt2, text = "OK", width = 10,
    command = function() tkdestroy(tt2))
tkgrid(tbut)

## A tk2mclistbox example
tt2 <- tktoplevel()
mlb <- tk2mclistbox(tt2, width = 55, resizablecolumns = TRUE)
# Define the columns
tk2column(mlb, "add", "name", label = "First name", width = 20)
tk2column(mlb, "add", "lastname", label = "Last name", width = 20)
tk2column(mlb, "add", "org", label = "Organisation", width = 15)
tkgrid(mlb)
# Fill the multicolumn list (we can use a vector, or a matrix of character strings)
item1 <- c("Bryan", "Oackley", "ChannelPoint")
items <- matrix(c("John", "Ousterhout", "Scriptics",
    "Steve", "Miller", "TclTk inc."), ncol = 3, byrow = TRUE)
tk2insert.multi(mlb, "end", item1)
tk2insert.multi(mlb, "end", items)
#### TO DO: bind events
# Ex: .listbox label bind date <ButtonPress-1> "sortByDate 
# See the example.tcl in .\libs\mclistbox1.02 for a more complex example
# Create a button to close the dialog box
but <- tk2button(tt2, text = "OK", width = 10,
    command = function() tkdestroy(tt2))
tkgrid(but)

### A simple tk2table example (Tktable is required here!)
myRarray <- c("Animal", "\"sphinx moth\"", "oyster",
    "Type", "insect", "mollusk")
dim(myRarray) <- c(3, 2)
for (i in (0:2))
    for (j in (0:1))
        .Tcl(paste("set tclarray(", i, ",", j, ") ", myRarray[i+1, j+1], sep = ""))
tt2 <- tktoplevel()
table1 <- tk2table(tt2, variable = "tclarray", rows = "3",
    cols = "2", titlerows = "1", selectmode = "extended", colwidth = "25",
    background = "white")
tkpack(table1)
