18. The Menu System
18.3.5 Panel Controls
Each panel contains a couple of control elements, so-called widgets (window gadgets), that
allow the users to set the options. Here we give a complete list of widgets used in the Bernese
menu system. There are the following five standard widgets:
The lineedit is used for simple user input which may consist of comment
text, a real- or integer-valued number, or an output file name. For
filenames the extension for the specific file type appears just right of
the field.
The checkbox is used if a simple yes/no answer is expected. With the
box marked the corresponding option is activated, with the box unmarked
the option is not active.
The combobox is used if the user has to select one of several predefined
alternatives. Depending on the option the list of defined values
is complete or additional values may be input.
The spinbox is used if an integer value in a given range is expected.
The radiobuttons are used if the user has to select one of several alternatives.
Some other control elements may depend on the setting of the
radiobuttons.
Apart from the standard control elements, three widgets were prepared especially for the
Bernese menu:
The uniline is used to generate input tables of variable length. It consists
of editable fields and two buttons. The +-button repeats the line
(the new line can then be edited), the--button deletes the line (the last
remaining line cannot be deleted). In some cases the unilines appear
without + and --buttons. In this case only the activated input fields
accept user input.
The selwin is typically used for selecting input files. This widget consists
of a lineedit and a selection button just right to it labeled with
the extension of the expected file type. Pressing the button, a standard
file-selection dialog appears allowing the user to select the desired input
file(s). Before pressing the selection button the user may restrict
the selection using wildcards * and ?. For example, if you specify I* in
the editable field and presses the selection button CRD you may select
from files ${P}/MYCAMP/STA/I*.CRD.
Depending on the specific input field, more than one input file may
be selected. In that case the string SELECTED appears in the field.
Pushing the selection button allows to check the names of the selected
files. The selwin file selection dialogue offers the possibility to browse
ASCII files. In some cases the widget is also used to select other items
than filenames, e.g., a subset of station names from a list.
The comment looks like normal text in the panel but it displays a
variable text (e.g., the name of the file currently edited in the panel).
It does not accept user input.
