DIALOG(2)DIALOG(2)NAME
dialog: prompt, getstring - basic dialog boxes
SYNOPSIS
include "dialog.m";
dialog := load Dialog Dialog->PATH;
init: fn();
prompt: fn(ctxt: ref Draw->Context, p: ref Draw->Image,
icon, title, msg: string,
dflt: int, labs: list of string): int;
getstring: fn(ctxt: ref Draw->Context, p: ref Draw->Image,
s: string): string;
DESCRIPTION
Dialog module provides two simple dialog boxes for use by wm(1) appli‐
cations. Init should be called once to initialise its internal state.
Prompt uses the graphics context ctxt to pop up a dialog box to prompt
the user to choose from a set of alternatives, or to acknowledge a mes‐
sage. The box is created near the northwest corner of the parent win‐
dow p, represented by the window's image. (If the parent window is a
Tk Toplevel t, for instance, the appropriate value is t.image.) If p
is nil, the box is centred on the screen. The box has the given title
and an optional icon. It displays the given msg and a number of but‐
tons, labelled with the strings in labs. The dialog box waits for the
user to push a button, and then returns the index of the button pushed
(the first element of labs is index 0). If the user types a newline,
the dflt value is returned. The button with the dflt index is spe‐
cially outlined in the dialog box.
Getstring pops up a dialog box near the parent window p. The box con‐
tains the msg and an entry widget. It waits for the user to type a
string and a newline, and then returns the typed string, without the
newline.
