wd commands to create common dialog boxes begin with wd 'mb ...'.

mb iconspec button-list title message ; General-purpose dialog box for giving the user information and waiting for a response

iconspec is info, warn, critical, or query. It signifies the importance of the message. It also controls the result: the result will be empty for all iconspecs except query; for query the result will be the selected button-spec, in lowercase, without the leading mb_.

button-list is a list of button-specs. Each button-spec creates one button in the dialog box. The button-specs must be chosen from: mb_ok mb_open mb_save mb_cancel mb_close mb_discard mb_apply mb_reset mb_restoredefaults mb_help mb_saveall mb_yes mb_yestoall mb_no mb_notoall mb_abort mb_retry mb_ignore. Put = before the default button (the first will be the default if you omit =)

title is the title of the dialog box

message is the message text.

Example: wd 'mb query mb_yes =mb_no mb_cancel "Model Run" "OK to continue?"'

The utility wdinfo, with arguments of title;text, executes wd 'mb info mb_ok title text. For example:

 wdinfo 'my title';'some text'
