我正在尝试使用 TCL/Tk 开发 GUI,因为那是 Pointwise 网格生成软件的“宏语言”。我发现一篇帖子讨论了一个名为的过程的使用,该过程tk_optionMenu
可在此处获得。问题是我不明白如何调用例程,也不明白如何将各种条目放入选项菜单。我想要的选项不是数字,而是不同例程的文本。此例程中的信息指出参数是“>=1”,而不是文本。例如,我想要一个选项菜单,以便用户可以选择在网格上使用哪种平滑方法。在我在 TCL 中使用网格格式设置的 GUI 中,我有几个位置要使用选项菜单。
使用格伦杰克曼的建议,我尝试了以下方法:
#!/usr/bin/wish
# the next line restarts using wish \
#exec wish "$0" "$@"
# interface generated by SpecTcl version 1.2 from /home/hh-eagle/ab/salter/bin/src/GLYPH/PrismEditor/GUI/PE_v01.ui
# root is the parent window for this user interface
package require Tk
proc PE_v01_ui {root args} {
# this treats "." as a special case
if {$root == "."} {
set base ""
} else {
set base $root
}
label $base.solver \
-text {Solver:}
set solvers {TriSmooth QuadSmooth VolSmooth K_lineSmooth}
tk_optionMenu $base.solvers activeSolver {*}$solvers
# Add contents to menus
# $base.solvers.menu add radiobutton -label TriSmooth
# $base.solvers.menu add radiobutton -label QuadSmooth
# $base.solvers.menu add radiobutton -label VolSmooth
# $base.solvers.menu add radiobutton -label K_lineSmooth
# Geometry management
grid $base.solver -in $root -row 2 -column 6
grid $base.solvers -in $root -row 2 -column 7 \
-columnspan 2
# Resize behavior management

# grid columnconfigure $root 1 -weight 0 -minsize 30 -pad 0
# grid columnconfigure $root 2 -weight 0 -minsize 30 -pad 0
# grid columnconfigure $root 3 -weight 0 -minsize 30 -pad 0
# grid columnconfigure $root 4 -weight 0 -minsize 30 -pad 0
# grid columnconfigure $root 5 -weight 0 -minsize 30 -pad 0
# grid columnconfigure $root 6 -weight 0 -minsize 30 -pad 0
# grid columnconfigure $root 7 -weight 0 -minsize 2 -pad 0
# grid columnconfigure $root 8 -weight 0 -minsize 2 -pad 0
# grid columnconfigure $root 9 -weight 0 -minsize 30 -pad 0
# grid columnconfigure $root 10 -weight 0 -minsize 30 -pad 0
# additional interface code
# end additional interface code
}
# Allow interface to be run "stand-alone" for testing
catch {
if [info exists embed_args] {
# we are running in the plugin
PE_v01_ui .
} else {
# we are running in stand-alone mode
if {$argv0 == [info script]} {
wm title . "Testing PE_v01_ui"
PE_v01_ui .
}
}
}
当我运行它时,我得到一个空白框,顶部带有图标化或关闭它的选项。取消注释或注释列和行配置信息没有区别。使用注释行填充 optionMenu 而不是{*}solvers
也没有任何区别。所以,有些东西是不正确的,我不知道是什么。
