雙R tctltk進度欄

Question

我的問題不是如何創建單個進度條，而是如何創建跟蹤和更新兩個不同過程的進度條。 例如，在同一個窗口中，我希望有一個欄跟蹤當前的模擬索引，而另一個欄跟蹤另一個數字序列...我當前的代碼是：

library(tcltk2)

pb1 <- tkProgressBar(title = "Simulation Progress...", min = 1, max = 10, width = 300)
pb2 <- tkProgressBar(title = "Simulation Progress...", min = 2000, max = 2020, width = 300)

for (index in 1:10){

setTkProgressBar(pb1, index, label = paste("Index",index))

for (year in 2000:2020){

setTkProgressBar(pb2, year, label = paste("Year",year))

}

}

我想將兩個酒吧放在一起，不要分開...任何幫助表示贊賞！

使用tkProgressBar ，您必須深入tcltk的深度，如下所示：

library(tcltk2)

root <- tktoplevel()

l1 <- tk2label(root,"Simulation Progress...")
pb1 <- tk2progress(root, length = 300)
tkconfigure(pb1, value=0, maximum=9)

l2 <- tk2label(root, "Simulation Progress...")
pb2 <- tk2progress(root, length = 300)
tkconfigure(pb2, value=0, maximum=20, maximum = 20)

tkpack(l1)
tkpack(pb1)
tkpack(l2)
tkpack(pb2)

tcl("update")

for (index in 1:10){

    tkconfigure(l1, text = paste("Index", index))
    tkconfigure(pb1, value = index - 1)

    for (year in 2000:2020){
        tkconfigure(l2, text = paste("Year",year))
        tkconfigure(pb2, value = year - 2000)


    tcl("update")
    }       

}
