strip.type

Do we strip the type from the names in results?

...

Pass further arguments to methods.

gui

The 'gui' object concerned by this dialog box.

Value

The modified 'gui' object is returned invisibly. Use its gui$res component to get the list of returned fields.

Details

The form content is defined by a named list. Items are default values, or a list of possible items, e.g., for the combobox. Names are labels displayed in front of each field in the form. Follow them by a code that represents the type of entry you want to use:

:TXT for simple (default) textual box,
:H for hidden text (password),
:RO for read-only text,
:NUM for null of positive integers with up/down arrows,
:CHK for checkbox: TRUE or FALSE,
:CB for read-only combobox,
:CBE for editable combobox,
:FL to select one existing file,
:MFL to select multiple existing files,
:SFL to select or create one file,
:DIR to select a directory,
:CDIR to select or create a directory,
:FN to select font and font size,
:DT to enter a date,
:CLR` to enter a RGB color,
:BTN` to create a button that execute some code,
:LBL to add a label.

For the moment, the form dialog box is only supported on Linux. You have to install yad to get access to it. On Ubuntu, you do so by sudo apt-get install yad. For other system, look at the documentation.
