From 113bdf6ae1819022d8c0d640b78a37c7d6b52723 Mon Sep 17 00:00:00 2001 From: Mathieu Othacehe Date: Fri, 23 Nov 2018 23:23:45 +0900 Subject: installer: Rewrite welcome page. The welcome page is the only page using absolute positioning for the newt components, so that the page occupies all the screen space. This is becoming too hard to manage, so switch to grid management like elsewhere, even if the result is less appealing. Also add an info text to the page with a mention on how to switch back to the original installer. * gnu/installer/newt/welcome.scm (run-menu-page): Use a vertically stacked grid instead of hard window placement. --- gnu/installer/newt/welcome.scm | 58 ++++++++++++++++++++---------------------- 1 file changed, 27 insertions(+), 31 deletions(-) diff --git a/gnu/installer/newt/welcome.scm b/gnu/installer/newt/welcome.scm index 8ed9f68918..3a0e45e198 100644 --- a/gnu/installer/newt/welcome.scm +++ b/gnu/installer/newt/welcome.scm @@ -26,20 +26,14 @@ (define-module (gnu installer newt welcome) #:use-module (newt) #:export (run-welcome-page)) -;; Margin between screen border and newt root window. -(define margin-left (make-parameter 3)) -(define margin-top (make-parameter 3)) - ;; Expected width and height for the logo. -(define logo-width (make-parameter 50)) -(define logo-height (make-parameter 23)) +(define logo-width (make-parameter 43)) +(define logo-height (make-parameter 19)) -(define (nearest-exact-integer x) - "Given a real number X, return the nearest exact integer, with ties going to -the nearest exact even integer." - (inexact->exact (round x))) +(define info-textbox-width (make-parameter 70)) +(define options-listbox-height (make-parameter 5)) -(define* (run-menu-page title logo +(define* (run-menu-page title info-text logo #:key listbox-items listbox-item->text) @@ -55,30 +49,27 @@ (define (fill-listbox listbox items) (cons key item))) items)) - (let* ((windows - (make-window (margin-left) - (margin-top) - (- (screen-columns) (* 2 (margin-left))) - (- (screen-rows) (* 2 (margin-top))) - title)) - (logo-textbox - (make-textbox (nearest-exact-integer - (- (/ (screen-columns) 2) - (+ (/ (logo-width) 2) (margin-left)))) - (margin-top) (logo-width) (logo-height) 0)) - (text (set-textbox-text logo-textbox - (read-all logo))) + (let* ((logo-textbox + (make-textbox -1 -1 (logo-width) (logo-height) 0)) + (info-textbox + (make-reflowed-textbox -1 -1 + info-text + (info-textbox-width))) (options-listbox - (make-listbox (margin-left) - (+ (logo-height) (margin-top)) - (- (screen-rows) (+ (logo-height) - (* (margin-top) 4))) + (make-listbox -1 -1 + (options-listbox-height) (logior FLAG-BORDER FLAG-RETURNEXIT))) (keys (fill-listbox options-listbox listbox-items)) + (grid (vertically-stacked-grid + GRID-ELEMENT-COMPONENT logo-textbox + GRID-ELEMENT-COMPONENT info-textbox + GRID-ELEMENT-COMPONENT options-listbox)) (form (make-form))) - (set-listbox-width options-listbox (- (screen-columns) - (* (margin-left) 4))) - (add-components-to-form form logo-textbox options-listbox) + + (set-textbox-text logo-textbox (read-all logo)) + + (add-form-to-grid grid form #t) + (make-wrapped-grid-window grid title) (receive (exit-reason argument) (run-form form) @@ -102,6 +93,11 @@ (define (run-welcome-page logo) installation and reboot."
