Tried on a slow mobile line now again as well without any problem. I get the same impression that we talk about something else that slows it down. As one can also see in the first minutes of my video: spotter opens right away: https://www.youtube.com/watch?v=j-dTp6i_P3s This was also done on a machine with a slow connection. The catalog stuff just appears "deferred" when the info was retrieved but the spotter tool opens right away and classes and others could be used as usual. Still it would not make sense to retrieve it anytime you open spotter - thats why I think a cache would be suitable so we do it just one time per image session. Thanks T.

On the other side of the world (where network is faster) one can just open spotter, enter a name or name fragment of a project/framework like "Roassal" hit enter and load it without much hazzle. I now added an option/setting so you can disable the spotter integration if required. See attachement. Will be in with the next iteration of catalog browser. Thanks T.

Fwd: Putting a RTBitmap image in the center of a RTPieChart and composite forms.

Sorry. Send from the wrong address. Here comes again. Cheers, Offray -------- Forwarded Message -------- Subject: Putting a RTBitmap image in the center of a RTPieChart and composite forms. Date: Wed, 11 Nov 2015 18:18:57 -0500 From: Offray Vladimir Luna CÃ¡rdenas <offray.luna(a)mutabit.com> To: Any question about pharo is welcome <pharo-users(a)lists.pharo.org> Hi, I'm just improving some demos for the Smalltalks2015 Argentina that I will be giving tomorrow so if anyone has some kind of quick answer I will be really useful. By the way the event has been really energizing, the are a lot of nice and good people here and the city is beautiful. Hopefully it will become some kind of yearly peregrination for me. So on the last minute improvements front, I have two questions: 1. I'm trying to put a RTBitmap image in the center of an RTPieChart... but I'm having problems to find size or center methods on it or its parent classes. 2. I would like to make a composite graph, but seems that I'm missing something with the associated subcomponents. Consider this: g works fine, but If I try to put it on a composite one I get this: So just axis without any data. So I'm using the wrong abstractions to embed a graph inside another or I need somehow to put the data explicitly on the composed graph. Any help will be welcomed, as always. Cheers, Offray

Re: [Pharo-users] How to find the cursor position relative to its text for TextMorph or RubTextFieldArea
by Dimitris Chloupis Nov. 11, 2015

Nov. 11, 2015

because its simpler to understand and because I made it work the way I wanted faster than the Rubric alternatives. For example finding the cursor position for a RubScrolledTextMorph is even worse and is located at textArea selectionInterval which I did not even find by myself because the name would never have me guessed that selection had anything to do with cursor position. But I was told so by another smalltalker at slack chat. And even though my code formating worked great with TextMorph via keyStroke message when I tried to port my code to the Rubric keyStroke alternative it stopped working and I did not manage to find out why before I finally managed to find how to get the cursor position from a TextMorph. Generally speaking Morphic is my first choice for the simple fact that when it comes to Rubric, Glamour, Spec or whatever else Morphic still remains the basis. So if I am going to learn Morphic anyway then I might as well make it my first choice and when it cant do what I want the easy way then I will look into the alternatives. Frankly I really like Morphic. Still new to it, but its generally design makes more sense to me than other pharo GUI APIs.

How to find the cursor position relative to its text for TextMorph or RubTextFieldArea
by Dimitris Chloupis Nov. 11, 2015

Nov. 11, 2015

At first I thought that TextMorph>>cursor would return me the position of the cursor relative to its text so if I have a text like "hello" and cursor (that blinking thing) was at "o" it would return 6 but no, whatever position I try it returns always 1 . With rubric I found no way to do this either. Anyone has a clue, or to I need some kind of pharo dark magic ? Is this a bug , a feature or something in between ?

Hi, currently to open a Playground via shortcut one has to type <cmd>+o+w, that's because it used to open Workspace. However since it now opens Playground the shortcut is no longer appropriate. So can we change it to <cmd>+o+p? (This shortcut is currently occupied by Monticello Browser, but that can be movd to <cmd>+o+m which is free.) You could argue that people are used to this shortcut, however that will not be true for newcommers, who will just see it as random naming (which it currently is). Peter

Roassal and custom morphs
by Dimitris Chloupis Nov. 11, 2015

Am I correct to assume that I can easily embed Roassal visualizations inside morphs ? Also where is the official documentation ? is this still it ? http://agilevisualization.com/#book

How to make an input field with some formating abilities
by Dimitris Chloupis Nov. 11, 2015

Nov. 11, 2015

What I want is to create a morph that has the ability to input text from the user that formats it automatically and allows for a limited amount of characters. This input field will be in the format of HH:MM:SS , (H)our (M)inute (S)econd. The : seperators will be entered automagically by the input field and of course the input field should accept numbers and preferably sensible ones , so seconds and minutes will have a maximum of 60, hours 24. Is this possible with the existing Morphs or is this something I must implement myself ? I have been looking to the textmorph and all its subclasses but I have not made a lot of sense out of it, it looks very messy code.

I have played with the code, and started writing some code which manipulates the Google services. It is really powerful. Also, Richard has developed a slick way of dealing with OAuth when running a client app. This is great!

Fast Table: How to solve dependency on FTTreeDataSource
by Offray Vladimir Luna CÃ¡rdenas Nov. 8, 2015

Nov. 8, 2015

Hi, I'm making some data storage in SQLite, because of its self-contained nature and because it let me focus on visualization by delegating some query and storage matters to the little database. But for some moments I have the data in an ordered collection, which starts to lag for 10.000 items. I would like to explore fast table as a way to storage my temporal objects before putting them in the database, but when I'm trying to install Glamour-FastTable there is a warning message about a dependency on FTTreeDataSource. I tried running the following code: ===== Gofer it smalltalkhubUser: 'estebanlm' project: 'FastTable'; package: 'FTTreeDataSource'; load. ===== but is not working. How can I solve that dependency? Thanks, Offray Ps: See some of you soon in Smalltalks Argentina. I'm already on Buenos Aires. Is a really beautiful city and having the opportunity to reconnect face to face with smalltalkers will be great after my last Squeak Fest talk in 2007.
