rebol [ Title: "Progress Bar With Read-thru" Date: 17-May-2006 Name: 'progress-bar-with-read-thru Version: 0.1.0 File: %progress-bar-with-read-thru.r Author: "R.v.d.Zee" Owner: "R.v.d.Zee" Rights: {Copyright (C) R.v.d.Zee 2006} Tabs: 4 Purpose: { "Progress Bar With Read-thru" was written to provide a simple progress bar script to the REBOL library. When using REBOL's internal read-thru function, only 5 lines are required to update a progress bar - see note 2. "Read-thru" is used to download a file to the disk cache - and to provide the data to move the progress bar. The method used to retrieve the downloaded file from the disk cache is also illustrated. } Notes: { 1. Missing Faces. Without "face/para/scroll: 0x0", the button faces scroll out of sight when the slider dragger was moved. (may not always be needed) 2. Monitor Download. These 5 lines show how to update the progress bar. 3. Recover Download. How to retrieve the downloaded file from the disk cache. 4. Refrence/Credit http://www.Codeconscious.com - recovery of the downloaded file from the disk cache Jipe, CoDeuR.OrG "Progress-bar qui fait pro" - updating the progress bar } library: [ level: 'beginner platform: 'all type: [tutorial how-to reference] domain: [user-interface] tested-under: 'linux support: none license: none see-also: none ] ] fiveLines: { stop: false read-thru/progress/update theUrl func [total bytes][ download-monitor/data: (bytes / total) show download-monitor not stop ] } theUrl: http://antwrp.gsfc.nasa.gov/apod/image/0605/iss2_sts114.jpg progressBars: layout [ size 540x430 backcolor maroon across space 0 seeImage: image 480x310 top left font-size 14 font-color gold seeImage-slider: slider 16x310 maroon olive [ scroll-para seeImage seeImage-slider ;------------------------------------------------------------------------------ foreach face progressBars/pane [ if face/style = 'buttons [face/para/scroll: 0x0] ; Note 1 ] ;------------------------------------------------------------------------------ ] return below credit: h3 300 silver space 3 downLoad-monitor: progress maroon olive across space 0 style buttons button 67 maroon buttons "Download" [ either connected?
