如何在"gframe"中添加上下文菜单? [英] How to add a context menu to a `gframe`?
问题描述
如何在gWidgets2
中的gframe
中添加上下文菜单?我尝试了以下构造,但似乎无法将addPopupMenu
附加到gframe
:
How can I add a context menu to a gframe
in gWidgets2
? I tried the following construct, but it seems that I cannot attach a addPopupMenu
to a gframe
:
require(gWidgets2)
w <- gwindow("gformlayout", visible=T)
f <- gframe("frame", horizontal=FALSE, container=w)
l <- glabel("Lorem ipsum dolor sit amet, \nconsectetur adipiscing elit.", container=f)
b <- gbutton("change name", container=f, handler=function(h,...) {
names(f) <- "new name"
})
lst <- list(gaction('world', handler=function(h,...) svalue(world) <- "world"),
gaction('continent', handler=function(h,...) svalue(world) <- "continent"),
gaction('country', handler=function(h,...) svalue(world) <- "country"),
gaction('state', handler=function(h,...) svalue(world) <- "state"))
add3rdmousePopupMenu(f, lst)
#addPopupMenu(f, lst)
add3rdmousePopupMenu(b, lst)
上下文菜单可以很好地附加到按钮上,但不能附加到gframe
上.那么,如何添加右键单击gframe
标签时会弹出的上下文菜单?
The context-menu is attached fine to the button, but NOT to the gframe
. So how can I add a context menu that would pop-up when right-clicking the gframe
label?
更新
根据答案,我尝试了以下代码:
UPDATE
As per the answers, I tried the code below:
require(gWidgets2)
f <- gframe("", cont=gwindow())
l <- glabel("label") # no cont argument
add3rdmousePopupMenu(l, list(a=gaction("Hi")))
f$block$setLabelWidget(l$block) # the voodoo
但是当我在label
上按right-click
时,我仅获得用于选择文本的标准Gtk上下文菜单:
But when I right-click
on the label
, I only get the standard Gtk context menu for selecting text:

推荐答案
@landroni我没有检查,但是如果可以将弹出菜单直接添加到gframe标签中会感到惊讶.但是使用Gtk可以解决问题.这是将弹出菜单放置在标签位置的方法:
@landroni I didn't check, but would be surprised if popup menus could be added to gframe labels directly. But with Gtk things can be worked around. Here is how you can put a popup menu in the label position:
f <- gframe("", cont=gwindow())
l <- glabel("label") # no cont argument
add3rdmousePopupMenu(l, list(a=gaction("Hi")))
f$block$setLabelWidget(l$block) # the voodoo
l$widget$setSelectable(FALSE) # may not be needed
对于用户是否直观,我让您决定....
