Table 18.2: List of metacommands defining the behavior of the widgets.
Metacommand Description Widgets default
cards List of items that can be selected in a combobox combobox
editable Combobox is editable (true) or not editable combobox not editable
emptyallowed User input may remain empty (true) or selwin false
an input is required (false) lineedit true
ext File extension (EXT xxx from MENU EXT.INP) lineedit, selwin no extension
group Groups of radiobuttons radiobutton
maxfiles Maximum number of selectable files (integer) selwin unlimited
multilineallowed Multiple values for a lineedit are allowed (true) lineedit false
path Absolute path (PTH xxx) or campaign directory
(DIR xxx) from MENU EXT.INP
lineedit, selwin no path
pointer Points to another keyword, e.g., selwin selects
from the list defined by this keyword
initmenu, selwin
radiokeys List of keywords that are activated by the
radiobutton
radiobutton
range Range and step for spinbox (integer for start,
end, step)
spinbox
activeif Keyword is active under the specified condition all widgets
check max Maximum value of a user input
check min
check strlen
Minimum value of a user input
Maximum length of strings (integer)
lineedit, uniline
check type Expected user input (integer, real, date, or
time)
menuaux Keyword value is prepared by the auxiliary (MENUAUX in all cases)
Fortran program (MENUAUX)
action Action performed by program MENUAUX
menuauxkeys List of keywords. The current values of these
keywords will be passed to program MENUAUX lineedit, selwin, uniline
updateifchanged The value of the keyword is updated only if a
keyword in this list changes
updateifsave Update the content of the keyword using the
MENUAUX-mechanism if the panel is saved
Required metacommands are combobox: cards
radiobutton: group
selwin: either path/ext or pointer
spinbox: range
menuaux: action
these multicolumn keywords are used to generate titles in input file tables generated by
the Fortran programs.
A number of metacommands are available to check the correctness of user input. The
command check type = integer, e.g., checks whether an input is an integer value. If the
user enters a value with an unexpected type the menu asks the user to correct the entry
when the user leaves the panel (by navigating to a different panel or by saving the panel
file). The user may go back to the panel to correct the value or insist on his input.
A metacommandactiveif allows to define conditions under which an input field is active or
not. If the specified condition on the values of other keywords is not fulfilled the field remains
inactive and does not accept user input. The metacommand activeif = COORD / is,
e.g., used to make an input field active if a coordinate file is specified in field COORD. Several
conditions may be combined by AND or OR . They are analyzed from left to right.
