以下是我的代码示例。 每当需要选择多个选项时重新打开菜单是非常烦人的。由于每次选中复选框,菜单都会自动关闭。 我该如何预防?
#!/usr/bin/env wish
frame .top
pack .top -expand yes -fill both
wm title . TEST
menubutton .top.fillmet -text "select fill metals" -menu .top.fillmet.mtls
set m .top.fillmet.mtls
menu $m
$m add checkbutton -label "fill m2" -variable fillm2 -onvalue "fillm2" -offvalue ""
$m add checkbutton -label "fill m3" -variable fillm3 -onvalue "fillm3" -offvalue ""
$m add checkbutton -label "fill m4" -variable fillm4 -onvalue "fillm4" -offvalue ""
$m add checkbutton -label "fill m5" -variable fillm5 -onvalue "fillm5" -offvalue ""
$m add checkbutton -label "fill m6" -variable fillm6 -onvalue "fillm6" -offvalue ""
$m add checkbutton -label "fill m7" -variable fillm7 -onvalue "fillm7" -offvalue ""
$m add checkbutton -label "fill m8" -variable fillm8 -onvalue "fillm8" -offvalue ""
$m add checkbutton -label "fill m9" -variable fillm9 -onvalue "fillm9" -offvalue ""
$m add checkbutton -label "fill m10" -variable fillm10 -onvalue "fillm10" -offvalue ""
$m add checkbutton -label "fill m11" -variable fillm11 -onvalue "fillm11" -offvalue ""
$m add checkbutton -label "fill m12" -variable fillm12 -onvalue "fillm12" -offvalue ""
pack .top.fillmet

也许一种不同的方法可以更好地用于这个特定的用户界面?
这将显示一个新的顶层窗口,其中包含一个选项列表
可以选择。全局fillm
数组将填充
结果
proc doOptions { } {
global fillm
set w .optfillmet
toplevel $w
for {set i 2} {$i < 13} {incr i} {
checkbutton $w.cb$i -text "fill m$i" -variable fillm($i) \
-onvalue fillm$i -offvalue ""
pack $w.cb$i -in $w -side top -anchor w
}
button $w.b -text close -command [list destroy $w]
pack $w.b -in $w -side top -anchor e
}
frame .top
pack .top -expand yes -fill both
wm title . TEST
# .top.fillmet.mtls ; # redundant line

.top.fillmet add command -label "select fill metals" -command doOptions
. configure -menu .top.fillmet
