有人可以告诉我如何给'tcltk'消息框顶级焦点在R?
我的MWE低于。如果您运行代码并拖动消息框,您将看到它总是落后于基本窗口(代表我的应用程序的主窗口)。
library(tcltk)
base = tcltk::tktoplevel()
tcltk::tcl("wm", "attributes", base, topmost = TRUE)
loadYN <- tcltk::tkmessageBox(title = "",
message = "I really wish I appeared at the top
level :(",
icon = "question", type = "yesno", default =
"no")
提前感谢您的帮助!
编辑:我找到了解决方法(虽然我仍然想象有更好的方法)。我只是操纵topmost
函数中包含的tcl
参数来实现我的需要:
library(tcltk)
base = tcltk::tktoplevel()
tcltk::tcl("wm", "attributes", base, topmost = TRUE)
# Changing focus of base frame
tcltk::tcl("wm", "attributes", base, topmost = FALSE)
loadYN <- tcltk::tkmessageBox(title = "",
message = "I really wish I appeared at the top
level :(",
icon = "question", type = "yesno", default =
"no")
# Changing focus of base frame
tcltk::tcl("wm", "attributes", base, topmost = TRUE)
这是一种解决方法,可以实现我的需要,但不会回答我原来的问题,所以仍在寻找答案:)
