error "please insert disk" (windows vm)

by Nicolai Hess

we have the following bug report 16928 <https://pharo.fogbugz.com/f/cases/16928/no-disk-in-the-drive-reply-to-World…> "no disk in the drive" reply to World | Save As (and other places) "On a clean Pharo4.0 #40618 image, on Windows 7 World Menu | Save As brings up a modal alert window, "There is no disk in the drive. Please insert a disk into drive <etc>" On my system, it does this 4 times. I'm assuming that each instance refers to one of the card-reader drives which are attached, but without a card inserted. This is a pain to deal with every single time a File Browser or World | Save As dialog is opened. Could the alerts either be - only raised when that specific drive is requested by a user action or, less preferably - given by a non-modal window, and fading away after a period" I was able to reproduce this error on squeaks and pharos window vm. (insert a usb card reader, with card, wait some time , remove only the card, every access on this drive, for example open a FileList and scroll to the drive letter). The solution I found is to call SetErrorMode( *SEM_FAILCRITICALERRORS)* I would like to propose the following change to sqwin32directory.c wrap the call to FindFirstFileW/FindNextFileW with UINT prevMode = SetErrorMode(SEM_FAILCRITICALERRORS); call FindFirstFileW/FindNextFileW SetErrorMode(prevMode); ... and call this functions in at least dir_lookup() (the other file/directory methods are save). Alternative solution, we could call the SetErrorMode function once at program start but I don't know if there are other "useful" errors message that we don't want to disable. I tested both solution, both seems to work fine. What do you think?

How to declare a script variable to hold attribute value in jQuery seaside

by Jayalakshmi Lade

Hi, I am new to jQuery in seaside and trying to convert the below jQuery script to seaside jQuery for activating tabs and to render the related data but on another tab click getting *val* as 'undefined'. *jQuery script:* $(document).ready(function(){ $('ul.tabs li').click(function(){ var tab_id = $(this).attr('data-tab'); $('ul.tabs li').removeClass('current'); $('.tab-content').removeClass('current'); $(this).addClass('current'); $("#"+tab_id).addClass('current'); }) }) *My Converted jQuery code in seaside:* html document addLoadScript: ((html jQuery: 'ul.tabs li') onClick: (html jQuery ajax callback: [ :val | self tabId: val ] value: (html jQuery this attributeAt: 'data-tab')), ((html jQuery: 'ul.tabs li') removeClass: 'current'), ((html jQuery: '.tab-content') removeClass: 'current'), (html jQuery this addClass: 'current'), ((html jQuery id: self tabId) addClass: 'current')). Please give me your valuable suggestions on this. Thank you and looking forward for your reply. *Regards,* *Jaya L*

Those are all possible ways of loading a project with Metacello (a project that does have a Metacello configuration defined). Load Configuration just loads the Metacello configuration class for that project. Nothing else. Loading a particular version (like stable or bleeding edge or a fixed number version) does load the code, packages and dependencies of that project. BTW note that if a project isn't in the ConfigurationBrowser it does not mean it doesn't exist nor it won't work in that Pharo. It could mean that noone did the effort of publishing the ConfigurationOf class in the correct repository and a couple of other tasks required by the Configuration Browser. > > I guess I could use a primer on the new modern way of managing code > packages. > > I have a project to do that will involve a raspberry pi 2, a data feed > from an arduino managing sensors, mapping/navigation, and a touch screen. > > In my googling I have spotted some articles on running Pharo on raspberry > pi, and open street map with roassal2.

Wow things have changed.

by Eagle Offshore

Looking at Pharo 4.0 First, I'm a little confused by the Configuration Browser - did this replace Monticello?. I'm not clear on the difference between a package and configuration and also the "Load Stable" vs "Load Configuration". Is Load Configuration the bleeding edge or something? I guess I could use a primer on the new modern way of managing code packages. I have a project to do that will involve a raspberry pi 2, a data feed from an arduino managing sensors, mapping/navigation, and a touch screen. In my googling I have spotted some articles on running Pharo on raspberry pi, and open street map with roassal2. I'm basically building an appliance here but would love to develop on my mac and deploy to the raspberry pi 2 as full screen. I looked at the release notes for raspbian OS and it seems a package 'squeak-vm' was updated in 2013 for it. Not sure about cairo for roassal2? Any pointers? I think this could be a really cool use case for Pharo. Thanks -Todd Blanchard

Nautilus with fasttable and transparenticons

by Nicolai Hess

Since we use FastTable in Nautilus, if you drag a Nautilus window, some icons become transparent. (protocol icons for "private" and "initialization"). This is because fast table scales all icons to size 16@16 and this will convert 8bit forms to 16 bit forms and this may lose transparency information. you can simulate this with f:= Form extent: 100@ 100 depth:32. fill := (GradientFillStyle colors: (Color wheel: 10)) origin: 50@50 ; direction: 0@50;radial:true. f getCanvas fillRectangle: (10@10 extent: 80@80) fillStyle: fill. f getCanvas frameRectangle: f boundingBox width:2 color:Color blue. (f asFormOfDepth:16) asMorph openInHand. drawing this imagemorph works on the display screen but if you drag the morph it becomes invisble (what you see is only the shadow). the same behavior if you start with a form of depth 8. converting a form of depth 32 to 8 or 8 to 32 works. 8 to 16 or 32 to 16 does not work. There were some discussions on pharo/squeak ML (search for "fixalpha") But I don't know where this is fixed in squeak, but it works in squeak. I don't know exaclty what's the problem, converting the form or displaying it? any ideas?
