Hi Offray,

In Glamour a presentation does not know about it's parent so what you want to do might not be possible. Now, it's not very clear for me what you are trying to do. Is the code available somewhere?

Cheers, Andrei

Hi,

Any help with this from anybody? I would like to work on this for a workshop tomorrow on data visualization with Pharo.

Thanks,

Hi,

I'm creating a menu for loading, storing files from my outliner and updating the software. The interface is something like:

============================ buildBrowser "Main method for building the interface for trees. Is getting long. Needs refactoring"

browser := GLMTabulator new title: 'Grafoscopio'.

browser column: #tree span: 2; column: [ :c | c row: #nodeBody span: 2; row: #nodeHeader ] span: 4. browser updateOn: GLMItemAdded from: #yourself; updateOn: GLMItemRemoved from: #yourself.

(browser transmit) to: #tree; andShow: [:a | self treeOn: a]. "Creating a self updatable body pane" (browser transmit) to: #nodeBody; from: #tree; andShow: [ :a | self bodyOn: a]. (browser transmit ) from: #tree port: #selection; from: #nodeBody port: #text; when: [:node :text | text notNil]; to: #nodeBody port: #neverland; transformed: [:node :text | node body: text asString]. (browser transmit) from: #tree; to: #nodeHeader; andShow: [ :h | self headerOn: h ]. (browser transmit ) from: #tree port: #selection; from: #nodeHeader port: #text; when: [:node :text | text notNil]; to: #nodeHeader port: #neverland1; transformed: [:node :text | node header: text asString] ============================

The "treeOn:" code for the menu is something like:

============================ treeOn: constructor "Shows the correspondent tree of a node"

 (constructor tree)

"Snipped code"

     act: [ UbakyeBrowser new openFromFile] entitled: 'Open/Load ...';
     act: [:x | x inspect] entitled: 'Save as ...';
     act: [:x | x inspect] entitled: 'Update Grafoscopio';
     act: [:x | x printString inspect] entitled: 'About ...'.

============================

Of course, the [:x | x inspect] is just a place holder for the real code. In the case of a new browser, it has been replaced for [ UbakyeBrowser new openFromFile]. Now I would like to access to the message "saveToFile" which is defined on the UbakyeBrowser-UI, but this is different from the "Open/Load" option menu, because I'm not creating a new browser with an existing file name as parameter, but saving the current tree in the browser, so this doesn't seems a message to be send to the current GLMTreePresentation tree, but to the current browser which contains that tree (the one that was defined with "buildBrowser" above) and that object doesn't understand the saveToFile message, because it was defined for the UbakyeBrowser class.

So, there is any way to send messages from the a Glamorous tree to the current instance of the UbakyeBrowser which is being displayed on the interface and contains that tree?

As usual, I don't know if I made myself clear, but if there is any way to make better questions, please let me know also about it.

Cheers,

Offray

Wow... I have been having so much learning/pleasure working with Glamour.... but this is a stopper... I don't know to circumvent this issue.

No worries. It's not so dramatic :) Until now I really did bot get into a situation where this was a show stopper.

Now, it's not very clear for me what you are trying to do. Is the code

available somewhere?

I'm trying to create and environment to write (interactive) documents using a tree like metaphor so there are some kind of deep nodes which are invisible to the exported file. Here is an screen shot of the original tree in Pharo and the exported file from that tree side by side here:

http://mutabit.com/deltas/repos.fossil/grafoscopio/doc/ tip/Figuras/intro-lado-lado.jpg

The pdf file of a still draft paper which was wrote completely using this prototype here (in Spanish):

http://mutabit.com/deltas/repos.fossil/grafoscopio/doc/ tip/bootstrapping-objeto-investigacion.pdf

The original format of this file is a STON file with all the "metadata" and deep nodes:

http://mutabit.com/deltas/repos.fossil/grafoscopio/doc/ tip/bootstrapping-objeto-investigacion.ston

I have added functionality to export to markdown from STON to produce the pdf (using pandoc). This is the output:

http://mutabit.com/deltas/repos.fossil/grafoscopio/doc/ tip/bootstrapping-objeto-investigacion.markdown

(it can be render from the web site but is better to download it).

The code is hosted here:

http://smalltalkhub.com/#!/~Offray/Ubakye/

And can be installed following this instructions:

http://wiki.hackbo.co/doku.php/herramientas:grafoscopio:instalacion

The script for loading STON is missing the package which causes an error.

Is my first project on Smalltalk (except from some Bots Inc, Etoys and Scratch approaches) so is rookie code with a lot of errors.

Cool project. It looks already impressive.

Anyway if you can take a look of it and see in there is any way to "save trees" to files or give any clue on how to solve the issue I really appreciate it. I will make some test to see if I get some ideas.

Replacing 'browser saveToFile' with 'self saveToFile' should solve the problem if I'm not missing anything. UbakyeBrowser is the main browser so it's save to call method on it using self. I still get some error when saving as there seem to be some hardcoded path to the file (/ 'home' / 'offray' / 'Documentos' / 'U' / 'Libertadores' / 'Grafoscopio' / 'bootstrapping-objeto-investigacion.ston')

Let me know if this helps or if you have any other questions.

Cheers, Andrei

Thanks again,

Offray
